Glossary
Backplate (retroreflective) – shields a
traffic signal from background obstructions.
Retroreflective backplates introduce
contrast and reflect light at nighttime.
Benefit-cost ratio (BCR) – the outcome of a
benefit-cost analysis, which is a systematic
process for identifying, quantifying, and comparing
expected benefits and costs of an investment.
Big Data – large, datasets, often collected perpetually
from mobile or other connected devices.
CAN – Boulder’s Core Arterial Network, a
proposed connected system of protected bike
lanes, intersection enhancements, pedestrian
facilities, and transit facility upgrades.
CDOT – the Colorado Department of Transportation.
Contextual factor – a factor possibly related to
crashes, such as roadway data (e.g., number of
lanes), intersection data (e.g., presence of a traffic
signal), land use data (e.g., commercial areas),
operations data (e.g., traffic volumes), or Big Data
(e.g., operating speeds from connected vehicles).
Countermeasure – an engineering solution that
can be implemented to correct a crash problem
or mitigate the likelihood of a crash occurring.
Crash modification factor (CMF) – used to compute
the expected number of crashes after implementing a
countermeasure on a street or at an intersection.
Cycle length – the time required for a complete
sequence of traffic signal phases. Cycle lengths
typically range between 80 and 150 seconds.
DRCOG – the Denver Regional
Council of Governments.
Fatal crash – a crash where one or more
people is killed.
High Injury Network (HIN) – defined by DRCOG,
the Regional High Injury Network identifies the
roadways with the highest number of fatal and
severe injury crashes (also known as killed and
severely injured crashes, or “KSI” crashes).
High Risk Network (HRN) – defined by the City
of Boulder, the network of Boulder streets that
features the most contextual factors associated
with fatal and serious injury crashes.
Highway Safety Improvement Program (HSIP)
– a federal grant program with the purpose to
achieve a significant reduction in traffic fatalities
and serious injuries on all public roads.
KSI crash - a crash resulting in a
fatality (killed) or serious injury.
Leading Pedestrian Interval – a three to
seven second head start for pedestrians when
entering an intersection with a corresponding
green signal in the same direction of travel.
Level of Service of Safety – a qualitative measure
that reflects how a roadway segment or intersection
is performing compared to other similar segments
or intersections in terms of crash frequency and
severity.
03Boulder Vision Zero Action Plan
Major intersection – an intersection where the
major street has multiple lanes in each direction.
Protected bike lane - an exclusive facility for
bicyclists that is located within or directly adjacent
to the roadway and that is physically separated
from motor vehicle traffic with a vertical element
Protected intersection – an at-grade intersection
in which bicyclists and pedestrians are separated
from cars. Vehicles turning right are separated from
crossing bicyclists and pedestrians by a buffer,
providing increased reaction times and visibility.
Protected left-turn (or right-turn) – consists of
providing a separate phase for left-turning (or right-
turning) traffic and allowing left-turns (or right-turns)
to be made only on a green left arrow (or right arrow)
signal indication, with no pedestrian movement
or vehicular traffic conflicting with the turn.
Rectangular Rapid Flashing Beacon (RRFB) –
rectangular-shaped yellow lights with light-emitting
diode (LED) arrays that flash a rapid sequence
when activated by a pedestrian; RRFBs are not
able to be integrated into nearby traffic signals.
Regional Transportation District (RTD) – the
regional agency operating public transit services
in the Boulder area.
Right-turn slip lane – at signalized intersections,
right turn lanes that bypass the traffic signal with a
triangular shaped island.
Risk Factor – a contextual factor shown through
statistical and spatial analysis to relate to crashes.
Safe Streets and Roads for All (SSRA) – a
federal, discretionary grant program providing
$5 billion in grants from 2022 through 2026 to
prevent roadway deaths and serious injuries.
Serious injury crash – a crash that results
in an incapacitating (life altering) injury.
Severe crash – a general term encompassing
both fatal and serious injury crashes.
Signal head – the portion of a traffic signal
containing the red, yellow, and green lights.
Systemic Safety – an approach to safety
involving widely implementing improvements
based on high-risk roadway features correlated
with specific severe crash types.
Traffic signal – also known as a
traffic light or stop light.
Transportation Improvement Program
(TIP) – the DRCOG program that identifies
all current federal- and state-funded
transportation projects to be completed in
the Denver region over a four-year period.
Vertical separation (bikeway) - a bikeway
type defined by the Low-Stress Walk and
Bike Network Plan as either a protected
bike lane or a multi-use path.

Executive Summary
Vision Zero is Boulder’s goal to eliminate all severe
crashes resulting in a serious injury or fatality.
The project team completed technical analysis to define a High Risk
Network that informs the Vision Zero Action Plan’s priority actions.
A summary of the findings regarding the High Risk Network (HRN) is:
The City of Boulder is developing an updated action plan to address areas of concern
identified in the city’s Vision Zero Boulder: Safe Streets Report, 4th Edition, 2022.
For this update, staff are creating a five-year 2023-27 Vision Zero Action Plan. The updated plan
incorporates community engagement, improves on the prior 2019-21 Vision Zero Action Plan,
develops a five-year list of implementation strategies and projects, and identifies opportunities
for federal, state, regional, and local funding.
The city completed two rounds of community engagement: the first in summer 2022 to better
understand community members’ attitudes and concerns regarding traffic safety in Boulder, and
another in winter 2023 to receive initial feedback on the 2023-27 Vision Zero Action Plan proposals.
The Vision Zero Action Plan is oriented towards the implementation of improvements across Boulder’s
transportation system, starting with the HRN and expanding to other streets, that will reduce the seven
common crash types, as well as address other location-specific safety issues. The Vision Zero Action Plan
includes four categories of actions to achieve Vision Zero through 20 specific actions.
Red light running crashes
Left-turn crashes
Right-turn slip-lane crashes
Right-turn on red crashes
Right-turn crashes

The Vision Zero Goal
Vision Zero is Boulder’s
goal to reduce the number
of traffic-related fatalities
and serious injuries to zero.
13Boulder Vision Zero Action Plan
Boulder first adopted Vision Zero in 2014, aiming
to eliminate fatal and serious injury crashes
by 2030. Boulder defines severe crashes as
those that result in a fatality or serious injury.
While the primary focus of Vision Zero is to
eliminate severe crashes, it also aims to reduce
minor injury or property damage only crashes.
Vision Zero is a priority of the Transportation
Master Plan (TMP) and informs the city’s other
transportation plans, projects, and programs.
Boulder’s Vision Zero Action Plan contains a series
of actions that the City of Boulder will take over
the next five years in pursuit of its Vision Zero goal.
Boulder’s first Vision Zero Action Plan contained
actions for the years from 2019-2021. This Vision
Zero Action Plan contains actions for the years
from 2023-27, building on the successes and lessons
learned from the previous plan, technical analysis of
crash and other data, and community engagement.

Status ofVision Zero
A summary of the 2022 Vision Zero: Safe Streets Report is:
Total crashes per year in Boulder have been trending down since
2001; however, severe crashes per year have remained steady.
The City of Boulder regularly prepares a Safe Streets
Report that reports on the progress of crash reduction
efforts, summarizes analysis of crash data, and
identifies crash trends and other areas of concern.
The crash data reported in this document comes from the City of Boulder’s Transportation & Mobility
Department database, which is derived from the Police Department’s Record Management System.
The information contained in these databases is updated periodically and may change over time
Areas of concern include:

17Boulder Vision Zero Action Plan
NINE PEOPLE WERE KILLED
Whereas the Safe Streets Report summarizes the
most recent three years of crash data (2018 through
2020), this Vision Zero Action Plan used five years
of crash data, from 2016 through 2020, to more
broadly inform crash patterns and the application of
location-specific engineering solutions.
Figure 1 shows the locations of all crashes, Figure
2 shows the locations of fatal and serious injury
crashes, Figure 3 shows the locations of pedestrian
crashes, Figure 4 shows the locations of fatal and
serious injury pedestrian crashes, Figure 5 shows the
locations of bicyclist crashes, and Figure 6 shows the
locations of fatal and serious injury bicyclist crashes
between 2016 and 2020.
Note: not all crashes were displayed on the maps due
to insufficient location data.

How We Developedthe Action Plan
Staff were successful in implementing many elements of the 2019-21 Action Plan (see Appendix A), including:
Made changes at 49 intersections to add:
Advanced Vision Zero improvements like bike lane and/or green pavement marking enhancements
with the pavement management mobility enhancements program, including on:
• Table Mesa Drive
• Lehigh Street
• Pine Street
• Folsom Street
• 17th Street
This Vision Zero Action Plan represents a significant shift
from the 2019-21 Action Plan. This Vision Zero Action
Plan outlines a prioritized set of fundable and actionable
projects and programs that can be implemented over the
next five years in areas that have the greatest potential to
reduce the number and severity of crashes.

• Pedestrian crossings
• 47th Street sidewalks
• New traffic signals
• Speed limit setting and signing

Community Engagement
The project team completed two phases of
community engagement to develop the Vision
Zero Action Plan: in the first phase, the public
was consulted to understand their transportation
safety concerns, and in the second phase
we informed the public of the draft plan.
The 2023-27 Vision Zero Action Plan was developed
using community engagement, Systemic Safety
analysis , and corridor analysis on the High Risk
Network. The Systemic Safety analysis reflects
both crash history as well as contextual factors
to proactively mitigate risk and to reduce crashes
before they occur, by pairing solutions to the
crash types most associated with the risk factors.
The resulting project list provides more specific
actions that can be undertaken to address
transportation safety and achieve Vision Zero.

PHASE 1 COMMUNITY
ENGAGEMENT
From summer to fall 2022, the community was
asked to share their traffic safety concerns when
travelling in Boulder. The City of Boulder hosted
a virtual open house for community members,
facilitated stakeholder meetings with Community
Cycles and the Center for People with Disabilities,
a hosted a survey and web map hosted through
the city’s engagement platform, Be Heard Boulder,
and hosted an in-person event at the San Lazaro
Mobile Home Park. Community members shared
over 700 comments on specific locations where
they felt unsafe traveling by foot, bike, and/or
vehicle. Appendix B includes a summary of Phase
1 engagement activities. This is what the city
learned through the online survey and web map:
• 37% of survey respondents have had personal
experience with a severe traffic crash, either
being seriously injured themselves or knowing
someone who had been seriously injured or killed
• The top four traffic safety concerns
of survey respondents were:
1. Distracted driving
2. Drivers not yielding to pedestrians or bicyclists
3. Speeding
4. Drivers and bicyclists sharing the road
• 66% of survey respondents choose whether
to walk, bike, or drive based on traffic
safety concerns for their trip route
• The top four traffic safety corridors are:
1. Broadway/South Broadway in the vicinity
of Iris Avenue, intersections adjacent to
the University of Colorado, Baseline Road,
Rayleigh Road, Dartmouth Avenue, and Table
Mesa Drive
2. Table Mesa Drive/South Boulder Road
from Hartford Drive to Foothills Parkway
3. Arapahoe Avenue between 28th
Street and 55th Street
4. 28th Street, primarily from Colorado
Avenue to Mapleton Avenue
PHASE 2 COMMUNITY
ENGAGEMENT
In winter 2023, the city hosted a virtual open
house, office hours with community members
for more detailed discussions, stakeholder
meetings with Community Cycles and the Center
for People with Disabilities, and a questionnaire
hosted through Be Heard Boulder. People were
generally supportive of the direction of the plan
and identified specific areas for enhancement
prior to finalization. Appendix C includes a
summary of Phase 2 engagement activities.

Systemic Safety Analysis
This plan uses a national best practice1 Systemic Safety analysis to
evaluate risk across the city’s entire roadway system. This approach
can identify patterns that may not be reflected in standard crash
data sources by pairing the data with contextual factors, such
as the number of travel lanes and roadway speeds, the type of
on-street bicycle facility, the types and timing of signals at an
intersection, if there are schools, businesses, parks, and other land
uses along the road, and Big Data2 from connected vehicles on
speeds and braking . Appendix D includes a technical memorandum
summarizing the Systemic Safety Analysis. From the 61 contextual
factors used for the analysis, six Risk Factors were found to account
for the most frequent and most severe crashes (Table 1):
• Multi-use path present
• Daily vehicle traffic between 5,000-10,000 vehicles per travel lane
• Signalized intersections
• A major intersection with no traffic signal
• Businesses and a mix of land uses present
• 85% of vehicle speeds at 30 miles per hour or faster

Figure 8 shows Boulder's street segments with one to six of the Risk Factors that were found to account for
the most frequent and most severe crashes.
The six Risk Factors are correlated with past
locations of frequent and severe crashes.
The cause of crashes is not always directly
related to a Risk Factor. For example, multi-
use paths and business or mixed use zoning
are correlated with crashes, but do not cause
crashes themselves. Crash analysis presented
later in this plan identifies the causes of crashes
at locations with a high number of Risk Factors.

High Risk Network
Boulder’s High Risk Network (HRN) consists of locations with five
or six Risk Factors.
Figure 9 shows the High Risk Network, Figure 10 shows the
High Risk Network where it overlaps with Boulder’s Core Arterial
Network (CAN). The Core Arterial Network is a connected
system of corridors in Boulder where the city is elevating work to
meet Boulder’s transportation goals. These corridors will feature
protected bike lanes, intersection enhancements, pedestrian
facilities, and transit facility upgrades. In addition to reducing the
potential for severe injury crashes, another purpose of this work is
to make travel by all modes more comfortable and convenient.
Figure 11 shows the High Risk Network where it overlaps with the High
Injury Network (HIN) and Critical Corridors from DRCOG ’s Taking Action
on Regional Vision Zero. DRCOG developed this High Injury Network
based on crash history and uses it to inform regional funding priorities.
The High Risk Network
accounts for just 7%
(26 centerline miles)
of City of Boulder
streets. Nearly all of
the High Risk Network
occurs on principal or
minor arterial streets;
however, the High Risk
Network includes only
35% of Boulder’s arterial
streets. Measured by
crashes per vehicle
miles traveled, the
High Risk Network has
roughly five times more
risk than all Boulder
arterial streets.
Managing risk and
mitigating crashes on
this small percentage
of streets can have
an outsized impact
on reducing fatal and
serious injury crashes.
Between 2016 and 2020,
• 48% of severe
crashes
• 56% of bike crashes
• 57% of pedestrian
crashes
occurred on the High
Risk Network.
Beyond these streets,
severe crashes are
much more dispersed.

Corridor Analysis
Each of the High Risk Network corridors was evaluated to identify proven safety treatments, or
countermeasures, that can reduce the common crashes identified by the Systemic Safety analysis. At locations
that had a high number of crashes , the team completed two additional analyses: 1) a review of five years of crash
data (2016-2020) to identify contributing patterns , and 2) Highway Safety Manual analysis to identify a location’s
Level of Service of Safety, which quantifies a location’s potential for crash reduction. Appendix E includes a
summary of the crash data review and Appendices F and G include summaries of the Highway Safety Manual
analysis. Figure 12 shows the locations where the project team completed Highway Safety Manual analysis.

typical solutions.
»Running red lights
»Left-turn crashes
»Right-turn slip lanes
»Right-turn on red crashes
»Right-turn crashes
»Multi-use path crossings
»Pedestrian crashes while crossing the street
Developed using the Safe Streets Report, an
engineer’s review of crash data, and Highway Safety
Manual analysis across the High Risk Network.
Prioritize locations with the most risk.
Implement solutions across the system where possible, and at specific
locations where systemic implementation is not feasible.
Generally, first the High Risk Network, then other
streets.
Developed by analyzing contextual factors and
crash data so we can manage all locations where
risk exists, not just locations where crashes have
occurred.

Common Crash Types
& Potential Solutions
Analysis of the High Risk Network revealed some common
crash types: running red lights, left-turns, right-turn slip lanes,
right-turn on red, right-hooks, multi-use path crossings, marked
crosswalks, unmarked and midblock pedestrian crossings,
and pedestrians in crosswalks against the signal.

RED LIGHT RUNNING CRASHES
CRASH TYPE DESCRIPTION
There are three common factors associated
with vehicles running red lights:
Signal size, the number of
signal heads per lane, and
missing signal backplates can
contribute to these crashes
Some High Risk Network
corridors coordinate traffic
signal timing; however,
some signals may be out of
sync which can contribute
to these crashes
Traffic congestion can create
driver frustration which can
contribute to these crashes
POOR SIGNAL VISIBILITY1.SIGNAL TIMING OUT OF SYNC2.CONGESTION3.
Upgrading traffic signals with
retroreflective backplates,
additional signal heads, or
signal heads in more visible
locations can provide lower-
cost, high impact crash
reduction benefits. However,
sometimes additional signal
equipment can exceed the
structural capacity of signal
poles and mast arms. In
these cases, the costs of
these solutions are higher.
Where signal coordination is out
of sync along a corridor, timing
adjustments can be made.
Where running red lights is
a result of congestion and
associated driver frustration,
increased enforcement during
peak travel periods, including
with red light cameras, is
an appropriate solution.

LEFT-TURN CRASHES
CRASH TYPE DESCRIPTION
There are three common types
of left-turn crashes:
A driver turns left and does
not yield to an oncoming
through vehicle
A driver turns left and does not
yield to a pedestrian or bicyclist
traveling in the crosswalk
A driver turns left and does
not yield to an oncoming

All Types
Continued implementation of the city’s Left-Turn Phase Operation Practice, which guides changes to
left-turn operation at signalized intersections. And updating the guidance with consideration of:
• Lower pedestrian and bicyclist (in crosswalk) volume thresholds
• A threshold for oncoming bicyclists in bike lane volume
• A threshold for people with disabilities (in crosswalk)
• Providing protected left-turn signal phasing when a pedestrian
or bicyclist pushes the pedestrian push button

RIGHT-TURN SLIP LANE CRASHES
A driver turns right and does
not yield to a pedestrian or
bicyclist in the crosswalk
or a driver is stopped in the
crosswalk creating collision
potential with a bicyclist; the
free movement of vehicles at
slip lanes is also difficult to
navigate for people who are
visually impaired
A driver turns right and stops to
wait to enter the intersecting
street and a second right-turning
vehicle driver does not stop;
inconsistency in design of right-
turn slip lanes can contribute
to this crash type by creating
confusion and hard braking
VEHICLE-PEDESTRIAN/
BICYCLIST
1.VEHICLE-VEHICLE REAR-END 2.
All Types
Consistent signing and markings are a low-cost solution that can clarify
expected behaviors and reduce the potential for crashes. For example,
adding “STATE LAW YIELD,” “2-WAY CROSSING” warning, “LOOK,” and/or
“YIELD” signage and painting high-visibility crosswalk markings.
At locations where there are many pedestrians and/or bicyclists, right-
turn traffic signals should be added or the right-turn slip lane should be
removed, when supported by delay and queuing analysis to ensure that
other safety issues are not created.
Where it is necessary to retain a right-turn slip lane, the slip lane itself
can be modified in a number of ways. The slip lane can be changed to
lower speeds with tighter angles at corners. Adequate storage can be
provided at the crosswalk for drivers waiting to merge. And, increased
or consistent yield signage can be provided at the crosswalk and at the
merge point.
Potential Solutions
Right-turn slip lanes exist at many signalized intersections in Boulder,
with most including raised crosswalks for people walking or biking to
more safely navigate to a pedestrian crossing island near the intersection.
A right-turn slip lane allows right-turning traffic to “slip past” an intersection
and avoid a red light which can reduce intersection delay.

RIGHT-TURN ON RED CRASHES
CRASH TYPE DESCRIPTION
Turning right on a red light is legal in Boulder unless
a sign prohibits the movement or if the movement is
controlled by a red arrow.
Vehicle drivers fail to yield
and enter the crosswalk
where a pedestrian or
bicyclist is present while
looking in the opposite
direction of the pedestrian or
bicyclist for oncoming traffic
Vehicle drivers turn across an
intersecting bike lane where
a bicyclist is present

BICYCLIST

All Types
Prohibiting right-turn on red, either with signs or traffic signals, can reduce this crash type. Greater
compliance can be achieved by prohibiting right-turns at priority locations, such as intersections with
high volumes of people walking or biking, while also considering impacts to delay, which can cause driver
frustration and non-compliance. Targeted enforcement and red light cameras can also increase compliance.

RIGHT-TURN CRASHES
CRASH TYPE DESCRIPTION
There are two common types
of right-turn crashes:
A driver turns right in front of
a bicyclist traveling parallel
to the vehicle in the on-street
bike lane; this is commonly
known as a right-hook crash
A driver turns right when a
pedestrian or bicyclist is in
the crosswalk
VEHICLE-BICYCLIST 1.VEHICLE-PEDESTRIAN/BICYCLIST

2.
Vehicle-Bicyclist or Vehicle-Pedestrian/Bicyclist (in the Crosswalk)
Providing a dedicated right-turn lane with adequate queue storage and protected right-turns with a red arrow
traffic signal phase, where the number of right-turning vehicles reaches a threshold, can mitigate these
crashes . Protected intersection elements can also mitigate these crashes. Implementation of these solutions
on Low-Stress Walk and Bike Network Plan vertical separation corridors should be prioritized.
Vehicle-Pedestrian/Bicyclist (in the Crosswalk)
Leading Pedestrian Intervals give pedestrians or bicyclists in the crosswalk a three to seven second head start
when entering an intersection with a corresponding green signal in the same direction.

MULTI-USE PATH CROSSING CRASHES
CRASH TYPE DESCRIPTION
There are two types of multi-use
path crossing crashes:
A driver on a minor street or
at a driveway crosses a multi-
use path to make a right-
turn onto the major street
collides with a pedestrian
or bicyclist traveling from
the opposite direction
than a driver is looking.
OUTBOUND RIGHT-TURN
VEHICLE-PEDESTRIAN/
BICYCLIST
1.
Outbound right-turn vehicle-pedestrian/bicyclist
Creating setbacks at multi-use path crossings at minor streets and driveways to provide storage for one
vehicle past the crosswalk can reduce this crash type by separating drivers’ turning from the multi-use path
crossing. Raised crosswalks can also help reduce this crash type. This solution is particularly challenging
to implement because of the number of multi-use path crossing locations and the amount of right-of-way
needed to create the setback, so this solution should be implemented at select locations, in particular with
corridor reconstruction projects.
Inbound vehicle pedestrian/bicyclist
Access management to restrict inbound left-turns will eliminate the conflict for inbound, left-turning vehicles.
Where access remains, and where inbound right-turning vehicles cross a multi-use path, these crashes can be
mitigated with appropriate sight distance and high-visibility markings or signage.
Potential Solutions
A driver on the major street
makes a right-turn or left-
turn across the multi-use

PEDESTRIAN CRASHES WHILE
CROSSING THE STREET
CRASH TYPE DESCRIPTION
There are three types of crashes that involve pedestrians
(or bicyclists in the crosswalk) crossing the street:
Potential Solutions
Vehicle-Pedestrian/Bicyclist at a Marked Crosswalk
At locations where the city’s Pedestrian Crossing Treatment Installation Guidelines guide staff to install a
marked crosswalk, installing pedestrian signals or Rectangular Rapid Flashing Beacons (RRFBs) at locations
with a lower number of vehicles and lower speed limit streets can reduce this crash type. This would require
an update to the city’s Pedestrian Crossing Treatment Installation Guidelines, and specifically the criteria for
crossing treatments in Table 1, Figure 2a, and Figure 2b. The update to the Pedestrian Crossing Treatment
Installation Guidelines should also address raised crosswalks. Subsequent to updating the Guidelines, existing
pedestrian crossings should also be updated incrementally over time as funding and staff resources allow.
Vehicle-Pedestrian Outside of a Marked Crosswalk
The city can implement new pedestrian crossings at unmarked or midblock locations consistent with
Boulder’s Pedestrian Crossing Treatment Installation Guidelines.
A driver on the major
street does not yield
at a marked crosswalk
(with no pedestrian
signal) when a pedestrian
or bicyclist is present
despite the crossing
featuring markings, signs,
or flashing beacons.
This crash occurs when a
pedestrian is struck by a
vehicle outside of a marked
crosswalk. In some cases,
these locations are legal,
unmarked crosswalks;
however, the rights and
duties of pedestrians
and drivers are not well-
understood by most people
in these settings.
This crash most commonly occurs at a
signalized intersection between a vehicle
and a pedestrian or a bicyclist in the
crosswalk. For these crashes the crash
reports and crash data indicate that the
pedestrian or bicyclist was unlawfully
in the crosswalk, usually because the
pedestrian signal had a “Don’t Walk”
signal. A pedestrian or bicyclist may enter
a crosswalk unlawfully for a variety of
reasons. In some cases, this behavior may
be encouraged by high pedestrian delay;
however, further evaluation is needed to
better understand the role that delay plays
in this behavior in Boulder.

The project team used three criteria to prioritize
engineering solutions at specific locations, or
projects, that emerged from the Systemic Safety
and corridor analysis. This prioritization method
applied to higher cost projects and stand-alone,
low-cost projects and not the improvements that
will apply to broad portions of the street system as
described in the previous section:
• Benefit-cost ratio (BCR) – for each project, the
team produced an order of magnitude cost
estimate. The team estimated the project’s
benefit according to the crash history at the
intersection, relevant Crash Modification Factors
(CMFs) for all intersection crashes, and cost
data from the National Safety Council’s (NSC)
Estimating the Costs of Unintentional Injuries,
2013 per CDOT’s procedures for Highway Safety
Improvement Program funding. The project
team prioritized projects where the estimated
benefits exceeded the estimated costs.
• Boulder’s Racial Equity Index – Boulder’s Draft
Racial Equity Index evaluates city census block
groups for level of need using five variables:
1. Proportion of the population
that are people of color
2. Proportion of the population
that is Hispanic/Latino
3. Household median income
4. Proportion of households living
below the Federal poverty line
5. The proportion of residents that are Housing
and Human Services aid recipients
Figure 13 shows Boulder’s Racial Equity Index.
The team prioritized projects in or adjacent to
Equity Index Numbers 4 or 5.
• Community engagement feedback – During
Phase 1 of community engagement for the
Vision Zero Action Plan’s development, the city
hosted a web map for community members
to identify specific locations of concern. The
team prioritized projects that had high levels of
BeHeardBoulder feedback. Figure 7 shows a heat
map of BeHeardBoulder Web map pin drops.

Overall Costs & Funding
The updated action plan represents a more focused set of actions
than what was included in the 2019-21 plan, and it is anticipated that
it will more effectively reduce fatal and serious injury crashes due
to the robust methodology and analyses supporting the actions.
Although the original intent was to develop a fiscally constrained
plan, the cost of countermeasures, especially higher cost projects,
exceeds the amount of city funds available toward Vision Zero
over the next five years. While an action of the plan focuses on the
pursuit of competitive external grant funds, the reality is that, due
to the nature of competitive grants and limitations on when funds
are available, it is possible that some of the recommended projects
would ultimately require local funds to be completed in the next
five years. For this reason, the plan prioritizes actions so that they
can be completed incrementally as resources become available,
recognizing that Vision Zero remains a top department priority.

Boulder Vision Zero
Phase 1 Outreach Summary
Stakeholder Meeting Notes
Meeting with Community Cycles on 8/1/2022
Notes:
•Community Cycles askes if we are going to publish results of the current Vision Zero
action plan.
o Deaths or serious injuries caused by young drivers was an example they cited.
o They asked if we are going to tie metrics to the current actions and whether we
will scrap certain actions in this update.
o We concluded that it would be helpful for our team to craft at least one sentence
describing the status of each Vision Zero Action Plan action.
•Community Cycles described the need to integrate Vision Zero across departments, in
addition to producing an action plan and set of projects.
o We discussed, philosophically, whether Vision Zero was “about the journey or
about the goal.”
o We discussed that this current update would be a five-year plan, with an
expectation to update it five years from now.
o Integration across departments and cultural shift came up again later in the
conversation in regards to the proposed CU hotel/conference center.
•Community Cycles asked what we will do on the CAN. We described how some safety
recommendations from this plan will apply to the CAN and can be incorporated into
future CAN plans.
•Community Cycles mentioned concerns over the proposed CU hotel/conference center,
safety analysis as a part of development review, and an interest in better integrating
safety into development review. City staff committed to discussing the idea with others
leading updates to the Design & Construction Standards.

Boulder Vision Zero
Phase 1 Outreach Summary
Meeting with Center for People with Disabilities on 7/22/2022
Notes:
•We discussed how we get crash data (police reports and counter reports); Craig
mentioned a concern that we need data regarding near misses and close calls.
•Craig mentioned concerns regarding how inadequate infrastructure
o This includes missing curb ramps and sidewalks, can lead to safety concerns
whereby people are required to walk or wheel in the street.
o This also includes routine maintenance issues (keeping sidewalks clear) and in a
good state of rehabilitation maintenance.
o We discussed how safety comments could differ in summer versus winter
depending on the issues people are confronting at a particular time.
•Craig mentioned concerns regarding crossing times, in that some people require
additional time to cross the street (a crossing of Arapahoe Avenue was mentioned as
missing curb ramps and requiring extra time to cross).
•Michael and Craig voiced concerns about Be Heard Boulder’s lack of accessibility for
blind people and people lacking internet access.
•Michael mentioned near misses he has experienced walking with a cane; he has difficulty
submitting comments about these concerns online without an e-reader.
•We discussed differences between comments received through the ADA self-evaluation
and accessibility audit versus comments on near misses from the Web map.
•We agreed to filter through Web map feedback to see if there were any quick action
items that demand attention.

Public Meeting PowerPoint
Welcome to the
Boulder Vision Zero Action Plan
public meeting. We will begin shortly.
Boulder Vision Zero Action Plan
Public Meeting # 1
June 29, 2022
What is Vision Zero?
•Vision Zero is Boulder’s goal to reduce
the number of traffic-related fatalities and
serious injuries to zero.
•Vision Zero operates under the principal
that fatal and serious injury crashes are
preventable and unacceptable and all
should be able to get around safely on
our streets.
What are Vision Zero’s Objectives?
1.Eliminate crashes resulting in fatalities
and serious injuries.
2.Reduce other types of crashes.
3.Improve travel comfort and security.
4.Enhance awareness of and community
engagement with Vision Zero.
5.Improve data and be transparent.
Vision Zero in Boulder
•Adopted in 2014.
•Most recently released 2022 Safe Streets
Report.
•Several Vision Zero projects implemented.
•Kicking-off development of Boulder Vision
Zero Action Plan.
Safe Streets Report
•First report in 2012 and three other
updates.
•Understand where and how crashes
are occurring in Boulder.
•Understand who the crashes
involve.
•Highlight areas of concern.
•Evaluate prior safety projects.

94% of severe left turn crashes occurred on arterial roadways
77% of severe pedestrian crashes occurred on arterial roadways
55% of severe bicycle crashes occurred on arterial roadways
Boulder Vision Zero Action Plan
•Companion to the Safe
Streets Report.
•Identify additional
strategies the city can use
to reduce fatal and serious
injury crashes.
Goals of the Vision Zero Action Plan
•Serve as playbook to achieving Vision
Zero.
•Seamlessly integrate into departmental
work plans.
•Allow for direct and candid dialogue with
TAB and City Council (regarding project
prioritization and funding opportunities).
•Assure accountability and bold thinking.
Systemic Safety Analysis
Evaluate risks across the entire transportation system, rather than
only managing risk at specific locations.
Compare historical crash
data against transportation
system risk factors such as:
•Vehicle speeds
•Traffic volumes
•Land uses
•Demographics
•Other factors
•Identify locations that may
not have experienced a high
number of fatal and serious
injury crashes to date but
have a higher potential to in
the future because they are
locations where many risk
factors overlap.

The left turn from Colorado to 28th is FAR
too short.
1200 28th Street 40.00802396 -105.2585989 I feel unsafe driving

This intersection feels very unsafe to me.
The one ways and the strange left turns
make it very confusing and hard to
navigate, also the steep incline on
Colorado makes it hard to see cars coming
when trying to make a left turn
1345 28th Street 40.01159249 -105.2601868 Other traffic safety

There's another disused, broken water
fountain here. Please repair all the water
fountains.

Hairpin turn for bicyclists with a narrow
bridge
1400 28th Street 40.0109841 -105.2588886 I feel unsafe bicycling

Unhoused people congregate in this area
and set up large encampments. I've had
multiple close calls with this group of
people intentionally trying to impede my
path as I'm riding downhill on 28th, like it's
some kind of game.
1400 28th Street 40.01081179 -105.2589583 I feel unsafe bicycling
here
This has become a permanent
encampment area with people and trash. I
don’t like biking through here, and I would
feel unsafe walking through this area now.
1601 28th Street 40.01483903 -105.2585006 I feel unsafe bicycling
here
You have to bike on the sidewalk here.
The sidewalk is uneven, it annoys the
pedestrians, and no cars look for you when
they make turns.
1678 28th Street 40.01623247 -105.2581502 I feel unsafe bicycling
here
drivers continually pull out into the multi-
use path, looking only left at oncoming
traffic. Crossing needs to be raised.
28th Street
1700 28th Street 40.02005136 -105.257864 I feel unsafe bicycling
here
There is no safe way to navigate this
parking lot. The lanes are narrow and
spots give poor visibility.
1728 28th Street 40.01809284 -105.2581719 I feel unsafe bicycling
here
The bike path that follows 28th can be
dangerous if you are riding your bike
against traffic on the path, since cars can
only turn right, they will not be looking for
you.
1728 28th Street 40.01789488 -105.2581429 I feel unsafe bicycling
here
Too many cars turn into the roads along
the 28th St mall without noticing bikes.
1770 28th Street 40.01833023 -105.2581636 I feel unsafe bicycling

1800 28th Street 40.01927158 -105.2581869 I feel unsafe bicycling

There needs to be better ways to
PHYSICALLY slowing cars down before
creeping over the intersection here. I've
nearly been hit multiple times. A stop sign
does not solve the problem.
1800 28th Street 40.01939439 -105.2581912 I feel unsafe bicycling
here
Bike traveling north on the multiuse path
are impossible to see from the exit of the
McDonald's drive thru (and car's leaving
the drive thru are impossible to see from
the bike path)
28th Street
1800 28th Street 40.01969018 -105.2582181 I feel unsafe bicycling
here
Drivers turning onto northbound 29th only
look to the left, i.e. to the south. They don't
see cyclists approaching from the north.
We often must wait for them, or unsafely
ride around them. This is the inherent
problem of "multi-use paths" as opposed
to protected bike lanes.
1800 28th Street 40.01942274 -105.2581859 I feel unsafe bicycling
here
In case you're wondering, the problem is
the McDonald's drive through exit lane,
which has poor visibility to northbound
bicyclists because of the architecture of
the store. This location is also a magnet
for panhandlers, who block the sidewalk.
1800 28th Street 40.01944369 -105.258191 I feel unsafe bicycling
here
drivers continually pull out into the multi-
use path, looking only left at oncoming

1800 28th Street 40.01918077 -105.2581322 I feel unsafe driving
here
Cars speeding and running lights, multiple
signs and lights, crosswalks, turns, etc. It’s
a chaotic intersection
1945 28th Street 40.02042555 -105.2585667 I feel unsafe bicycling
here
The pavement at this intersection is
horrible and has huge dips that are jarring
to bicyclists.
1964 28th Street 40.02161691 -105.2581751 I feel unsafe bicycling
here
People in cars coming out of target only
look left, rarely right. Lots of near misses
for me here and once was actually hit (no
injury or damage though, thankfully. Did
not report it.). People in the cars need to
pull into multiuse path to see oncoming
traffic, unfortunately.
28th Street
2121 28th Street 40.02337473 -105.2580786 I feel unsafe walking
here
No good pedestrian access to this area
after crossing 28th at the crosswalk. Either
cut thru bushes or walk along narrow
parking lot with no real place for
pedestrians to be.
2121 28th Street 40.02335863 -105.2581644 I feel unsafe bicycling
here
No good way to avoid cars poking out into
the multiuse path. Most people don't look
right when entering the multiuse path
because they are too busy looking at
oncoming traffic on their left. Then they
block the multiuse path and there's no way
to bike around them.
2555 28th Street 40.02673526 -105.2596825 I feel unsafe bicycling
here
It looks so simple on this map! But when
you are leaving the bike path here, you
need to meander a bunch to get to where
the curb cut is to cut thru the parking lot to
28th St.
2625 28th Street 40.02651361 -105.2582502 I feel unsafe bicycling
here
Random threats from the homeless here
over the years while biking by. It's not the
nice ones that I worry about, it's the violent
mentally ill people who are on a drinking
binge or having some kind of mental crisis.
Sometimes the encampment takes up
nearly the whole path and it's difficult to
navigate through.
2625 28th Street 40.02646579 -105.2588403 I feel unsafe bicycling
here
visibility is poor and the houseless
population take up a chunk of the path on
a regular basis
28th Street
3040 28th Street 40.02990585 -105.2581912 I feel unsafe bicycling
here
Is this supposed to be the sidewalk? It's
very dangerous to ride on the sidewalk
between Valmont and Iris on the east side
of 28th. Lots of sharp turns, parking lot
entrance/exits, and poorly maintained
concrete
3185 28th Street 40.03270782 -105.2583951 I feel unsafe bicycling
here
28th street needs bike lanes. Cyclists end
up using the sidewalks to stay safe.
3300 28th Street 40.03445756 -105.2582127 I feel unsafe walking
here
The sidewalk gets so narrow and is in poor
condition right here
3390 28th Street 40.03611274 -105.2575368 I feel unsafe bicycling
here
This parking lot is really degraded and full
of potholes. There is a huge weird paved
hill right here that is a road hazard. A
camp has dropoff and pickup by the
Walgreens and so this area gets a lot of
traffic by car and bike.
770 28th Street 40.00073438 -105.2586848 I feel unsafe driving
here
Very short merge here and cars on 36
have already accelerated out of Boulder
and do not make space for merging.
910 28th Street 40.00399507 -105.258556 I feel unsafe driving
here
The rapid deceleration here always makes
me feel on edge

985 30th Street 40.00480867 -105.2531219 I feel unsafe bicycling

I feel unsafe trying to merge with traffic in
the construction zone when on my bike.
Drivers do not like giving space to bicycles
trying to get through the construction zone.
In addition, drivers speed into and out of
the zone in their haste and impatience.
Vehicles with illegal mufflers also create
huge noise problems that are never
addressed. I would like to see police
stopping and ticketing unsafe,
disrespectful drivers here more regularly.
996 30th Street 40.00517027 -105.2531165 I feel unsafe driving
here
Drivers making left turns into and out of
Euclid on the west side (Adams Circle) are
frequent causes of near misses, squealing
tires, fender benders, and general bad
behavior. This is a dangerous intersection
made worse with the construction zone.
Too many impatient, aggressive drivers
trying to get into and out of the apartments
west of 30th.
1121 30th Street 40.00716431 -105.253389 I feel unsafe bicycling

The buses and cars that travel on 30th

project will improve this.

30th is far too narrow to safely
accommodate all the bikes and cars. In
particular, I hope the construction fixes the
intersection at 30th and Colorado.
1480 30th Street 40.01085246 -105.2541143 I feel unsafe bicycling

1520 30th Street 40.01100242 -105.2534502 I feel unsafe bicycling

This part of the creek path is sometimes
flooded and the underpass closed. There's
no way to safely cross 30th if the
underpass is closed and you have to make
a really long detour (or run for your life).
1585 30th Street 40.0137618 -105.2538836 I feel unsafe driving

I had an accident around here. I was hit.

1585 30th Street 40.01438219 -105.253948 I feel unsafe walking

Even though this is an area fairly heavily

people driving cars are not generally
paying attention. I have known many
people who've gotten hit walking or biking
here.

1585 30th Street 40.01425482 -105.2539587 I feel unsafe walking

There need to be turn arrow lights here.
Eastbound cars on Canyon turning North
onto 30th seem to be in danger from
Wesbtound cars coming from the road
between Concentra Urgent care and Best
buy, who accelerate to get around cars in
the turn lane to head South on 30th
2500 30th Street 40.02680322 -105.2535696 I feel unsafe bicycling

Very hard to access businesses and
neighborhoods on the other side of the
street when biking. Narrow bike lanes, lots
of round utility clean-out holes drilled but
not refilled, heavy traffic, debris in lanes,
no pedestrian crossings.
2828 30th Street 40.02797181 -105.2537227 I feel unsafe bicycling

I wish this stretch of road along 30th could
continue the wide sidewalk here (between
valmont and mapleton). Its hard to cross
the street to be in the bikelane going the
correct direction and the sidewalk here is
the standard 4 ft, while from mapleton to
arapahoe is the wide bikelane sidewalk.
30th Street
2995 30th Street 40.02910552 -105.253728 I feel unsafe bicycling
here
The bike lane on 30th (southbound) is
uneven and narrow. I feel unsafe biking
too close to the curb on a slanted surface,
and the pavement meets concrete in
almost the exact middle of the bike lane
which is uneven and causes me to crowd
toward the car lane. Cars go above the
speed limit on 30th and I typically try to
avoid it because it feels unsafe, but that is
not always possible.
3065 30th Street 40.030498 -105.2533901 I feel unsafe bicycling

Wouldn't it be sweet to have a bike line
along the farmer's ditch that connects from
Howard Hueston, under 30th to the off-
street lane along Valmont?
3121 30th Street 40.03364743 -105.2536639 I feel unsafe bicycling

There needs to be a safe crossing of 30th
for cyclists and pedestrians here. Lots of E-
W demand to get to Naropa, Diagonal
Plaza shops, apartments, Howard Heuston
Park, etc.
3121 30th Street 40.03259692 -105.2536368 I feel unsafe bicycling

Feels very uncomfortable to bike here.
Narrow, sloping bike lanes, fast traffic due
to excessively wide street. Needs a road
diet to 3 lanes with protected bike lanes
and multiple pedestrian crossings. High
density neighborhood with many lower-
income residents, including many of color.
3350 30th Street 40.03585791 -105.25361 I feel unsafe driving

People unexpectedly play frogger to walk
across here to their homes (I would guess
they are going home). Maybe they need a

Cars build up a decent amount of speed
on this straight stretch of 47th, and the
crosswalk is very subtle. It's common for
cars not to stop for me, both when I'm
walking and bicycling.
-People noted a general concern with travel speeds on 47th Street
-Multiple people walking noted that there are no walkways across the train tracks
-People walking generally noted the lack of continuous walkways and lack of comfortable crossing locations

This intersection feels unsafe for all modes
(and I've personally witnessed a crash).

This is an extremely sketchy place to turn
right from Diagonal/Iris on to 47th street.
Cars merge with cycle lane at excessive
speed and often do not stop for the turn,
regardless of signal status.

As part of the "quiet crossing" project at
this railway, we were told there would be a
sidewalk put in. The project is now
"complete" but there's no sidewalk either
side of the road and pedestrians have to
either walk on the bike lane, or in the
gravel along the verge. Additionally, the
property owner of the office building to the
north of this location has allowed the
shrubs to completely block the sidewalk,
so anyone walking needs to go into the
road where there's an island forcing cars
towards the shoulder. Where's our damn
sidewalk we were promised?!

Just where are we supposed to walk?
There's no sidewalk, the bushes stick way
out into the road, and this spot is a choke
point for both cars and bicycles because of
the traffic divider. I walk here every day
and it's extremely dangerous. I end up
walking in rocks and mud next to the
railway most of the time because it's too
sketchy to walk in the bike lane into

Cars usually zoom through this right turn

scary in winter when there is ice on the

just skid right into the island.

Wanted to get out of the sudden rain/hail

Arapahoe is treacherous for bicyclists from

The left turn cycle from Arapahoe EB to
29th NB is way too short, and since the
flashing yellow was eliminated, you have a
race from 28th to this intersection, with
most people in the wrong/left lane who
aren't turning, and then left turners sit at
an empty intersection for a full light cycle
before having to rush to get through before
the light inevitably changes before
everyone has made it through. At least
bring back the flashing yellow so that
people are sitting idling for an empty road
when it's safest to turn.

I've had friends who were crossing

cars turning from northbound Foothills
onto eastbound Arapahoe. There is no

coming and they travel very fast.
4410 Arapahoe Avenue 40.01490329 -105.2405745 I feel unsafe driving

Drivers often fail to yield when they take
this turn lane from westbound Arapahoe
onto northbound Foothills. They
sometimes come to a complete stop in the
traffic lanes on Foothills when they realize
how hard it is to merge, and sometimes
when I am waiting for a gap, cars behind
me will aggressively honk or get
antagonistic simply because I'm waiting for
my turn to go from behind the raised
crosswalk. This would be better served by
having the turn ramp have a stripe painted
where cars should stop for the yield, by
getting its own lane for more than ~50 feet,
and there should be those flashing lights
embedded in the crosswalk to alert cars
when peds/bikes are trying to use it

There are two safety concerns when biking
southbound through the Arapahoe
underpass: Bikes go downhill into the
underpass in an S-curve. At the bottom of
the curve one cannot see what is ahead.
Two things are often ahead: 1. Homeless
people sleeping in the underpass. 2. A
huge patch of ice. There are warning signs
about the ice but maybe the drainage
problem could be solved?

This is a sketchy left turn to make (turning

eastbound traffic on Arapahoe, east of
Cherryvale, drivers often speed and
aggressively cut one another off as they
approach the merge where it becomes one
lane for cars. There's often a long line of
stopped traffic between here and 63rd
street, and drivers unfamiliar with the area
and its unusual merge may end up waiting
a long time because they don't realize until
it's too late they need to merge left

Even though there are signs letting drivers

The situation where right turns from

There's no indication of the turn-only lane
markings until right when you get up to
them, so people often have to merge at
the last second, which creates a traffic
jam. Put some signage for drivers further
back east along Baseline so it's clear
which lane is going straight vs turn only
well in advance, and clearly marked lanes

The bike path along this stretch feels
dangerously close to traffic traveling at a

that drive off the road, over the bike path

Traffic speeds on Broadway make it a
stressful experience outside a car,
especially when crossing the street. The
roadway is too wide and it encourages
drivers to go fast, which feels dangerous
as a pedestrian. Some of the sidewalks
are also insufficiently wide and separated
from speeding traffic, as seen at the
intersection with North St.

I was on Cedar crossing Bwy (eastbound)
on my bike, and was almost run over by a
car. I came closer to being killed by a car
than ever before in my life! The car
(traveling northbound) trying to avoid me,
ran up on the sidewalk. I reported it to
police but they did NOTHING. They said
an officer would contact me, but never did.
I assume that since I wasn’t injured,
although came within an inch of being
killed, they didn’t bother investigating the
incident. Crossing Bwy on Cedar is a total
nightmare. I am 75 years old and I
typically bike around town when running
errands - which is most days.

Light at Iris & Broadway has issues with
the giving the "Walk" signal to cross
Broadway. If the push the button it often
makes you wait several cycles until giving
the walk (if it's green for Broadway when
you push, it'll then go green for Iris with
NO walk, then back to green for
Broadway, then again the green for Iris
when it'll finally give you the walk to cross).
See a lot of elementary kids from Foothill
who get frustrated and end up not waiting
that long time.

The right turn red arrow from Iris onto
Broadway doesn't seem to work properly.
It should light when there's peds walking or

Light at Linden goes to flashing yellow in

flying down the hill and there's no way to

time to slow after steep hill)

When the light changes to flashing yellow
on snowy days, peds cannot cross the
street at all. The ped crossing signal is
deliberately disabled. We cannot get to the
bus when the ped signal is disabled. The
argument that cars going downhill might
not be able to stop is bogus. Instead, they
must drive more slowly. City should set a
temporary 10mph speed limit for the
downhill between Norwood and Linden.

Hands down one of the most dangerous
sidewalks in the City. This sidewalk is
heavily used for school kids, gets bus and
car splashed with snow, water spray, mud,
and is within inches of cars traveling 40-50
mph. I'd love to see this sidewalk
physically protected with a jersey barrier
style stub wall or better yet, a broadway
ped crossing with lights installed at Ash.
Ash is where most of the neighborhood
crosses broadway, especially with bikes
that can't fit up the ramp to the north by
NOAA. Would really be nice to slow the
speed of Broadway down from 40
mph...coming north and down the hill cars
are coasting at speeds of +50
mph...again...within inches of Creekside
elementary school kids.
250 South Broadway 39.99269559 -105.2583821 I feel unsafe bicycling

Ash is the most-used bike and pedestrian
access to the west of Broadway bike path.
Cars are going 40-50 mph at this location
and would be nice to change this to a
flashing ped crossing like so many other
locations in the City. Crossing broadway at
a light near Darley is a dangerous
alternative as the sidewalk is inches from
traffic buses, cars, snow plows and
routinely splashes the sidewalk users
(myself included) with nowhere for the
pedestrian to hide.

The stretch from Pine to Arapahoe needs
protected bike lanes. North/South through
traffic should move to 28th. The bike
"lanes" are very narrow (basically gutters)
and cars are going very fast. It's great that
north Folsom has protected lanes but then
it just dumps you into the gutters here.
Bicyclists need a safe north/south corridor.

1855 Folsom Street 40.01896316 -105.2631372 I feel unsafe bicycling

The bike lanes on Folsom between Spruce
and Arapahoe are narrow and dangerous.
Debris often collects in them since they are
right up against the curb, and cars pass at
high speeds with no protection for adjacent
cyclists. This is one of the scariest places
to ride a bike in the city given the traffic
levels, speeds, and lack of adequate
space, and it's a stark contrast from the
curb-protected lanes farther north on
Folsom. These bike lanes should be
upgraded to match that standard.

The length of the light E/W bound is

increased to match the time for cars.

This entire area is a disaster. There is a
mixture of high speed highways, merging
zones, stop lights, and pedestrian and
cycling crossings that take up acres of
prime real estate and endanger everyone.
The whole thing should be demolished and
replaced with a simple interchange like at
Valmont, but with underpasses for cyclists
and pedestrians. Diagonal highway has
many existing stoplights, not sure why
there's a whole spaghetti interchange here
at all taking up so much space and
hindering pedestrians and cyclists
movement (and safety). The diagonal
project from 5 years ago just made this
corridor faster and was a huge waste of
resources.

BNSF installed a chain-link gate in their

Terrible merge here. Traffic coming off of
Foothills has the right of way, but traffic
waiting at the yield merge try to turn it into
a zipper merge. It is super hard to be
watching for someone there to start driving
while they’re supposed to be waiting and
to also pay attention to the traffic in the
other two lanes. They only have to watch
for space to merge, yet 90% of the time
they go when they shouldn’t. I drove this
route every day for six years while taking
my kids to school and it was a miracle I
never got in a wreck.

The street is too wide for the intended
speed limit. Despite the crosswalk and
signs, cars frequently ignore pedestrians.
I've played chicken with many self-
important drivers here. I would recommend
the sidewalk be raised to sidewalk height
to slow cars approaching downtown to the
posted speed limit (probably another will
be necessary at 21st) and making use of
the road width to add a chicane along this
stretch while narrowing the lane.

very low angle turn at high speeds. Car

While it doesn't happen often, city vehicles
traverse the bike path while driving

It would be nice to have underpass here

nice, but it dead ends here and just a few
blocks west behind Google. Connections
here and behind Google would make it

The two signaled interchanges on Pearl at
Foothills force bikes on the Foothills MUP
to wait an unnecessarily long time at
unsafe locations.
Currently, left turns from Pearl onto
Foothills get a long signal phase in the
afternoon at both signaled interchanges on
the east and west sides of the highway.
The problem is that this same phase also
includes a green for traffic continuing
straight east or west, even though east-
west traffic is blocked by the upstream
signal on the opposite side of the highway.
Engineers should eliminate the east-west
greens from this signal phase to allow for a
walk signal across Pearl with the left turn.
Alternatively, the city could make the pork-
chop island at the south-east corner as
large as those at the other four corners, so
people could feel safer waiting here.
4740 Pearl Parkway 40.02277537 -105.2458155 I feel unsafe walking

The light to cross Pearl on the Foothills
path has a very long wait cycle, especially
during rush hour. People often run the red
light during gaps in traffic which is now
legal, but still not very safe. See Gabe's
suggestion for combining the left turn
arrows with a longer walk cycle.

The red light at the bike/pedestrian
crossing is way too long. After a very long
wait, when the westbound traffic on Pearl
finally stops for the left turn signal from the
eastbound traffic onto Foothills,
bikes/pedestrians often start crossing on
red but don't realize that the eastbound
light is still green on Pearl. I have seen
many near hits because the vision of the
eastbound traffic is blocked by the left
turners. The red phase needs to be
shortened significantly and the left turn
green from Pearl onto foothills should be
moved to the beginning of the green cycle
on Pearl.

This is a major unsafe intersection for
walking, biking and accessing buses for
crossing Table Mesa via Yale Road. The
car traffic is heavy and fast. The school
crossing light only covers the east bound
lanes. The west bound lane (plus the bike
lane) which makes crossing two lanes of
traffic are not covered by the crossing
signal because the city doesn't recognize
the danger to pedestrians who have to
cross the bike lane first and stand in it
while trying to find a break to cross the
west bound traffic lane. They claim that
the westbound lane is only one lane and
thus doesn't need a signal. I watch all our
young kids trying to bicycle across that
intersection to go to the middle schools
and Fairview High and it is dangerous.
Please reexamine this decision and make
the school crossing signal work for both
west and eastbound traffic. Let's be
inventive here for safety!

I feel unsafe letting my children cross this

Traffic is too heavy and fast on Table
Mesa Drive. If we truly want
pedestrian/bike safety and 15 minutes
neighborhoods, we need to make the
areas adjacent to the shopping centers
and transit centers safe for peds and
bikes. There are few ped crosswalks on
Table Mesa drive and on Gillespie. Cars
coming down the hill move too fast.
Transportation Dept: Please examine
traffic flow in South Boulder. Note it is
channeled to Gillespie then Table Mesa to
access Broadway. For wildfire evacuation,
for reducing traffic load on Gillespie/Table
Mesa/shopping center and transit center,
please consider putting signaled
intersections at Darley and Broadway and
Grinnell and Broadway to funnel traffic
from south Boulder to Broadway as rapidly
as possible.

I'd like to add to the calls for safe
bike/pedestrian infrastructure here. This is
a natural crossing point from the shopping
center to the Broadway underpass. The
sidewalks across the intersection have
curb cuts, but we need striping and yield
signs here so people can safely cross all
four lanes of Table Mesa Dr. to get to
Harvard and the multi-use path. Drivers
zoom through this area to make the green

The bike gutter here is not sufficient. This
is a stressful ride. A lane should be taken
to create protected bike infrastructure in
both directions and a center turn lane
created. But volume is high enough here
that a roundabout would then be needed at

Left turns onto Martin are very stressful.
Without a turn lane, one is always
concerned about being rear ended while
waiting for an opportunity to turn. That fear
is compounded by the realization that,
when stopped to await a chance to turn,
cars approach from behind often change
to the right lane at the last second, leaving
the driver behind them with little time to
realize and react to the fact that there is a

The southbound approach to this
underpass from the north is very steep and
needs a convex mirror at the tunnel so
cyclists can see oncoming others. My kid
had a head-on collision with an electric
scooter rider here, which gave them a
concussion and totally wrecked their bike.
During winter months, water dripping from
the roadway freezes into sheets of ice and
creates a dangerously slick surface to be
going so fast on. The lights in the tunnel
are frequently broken or burned out.
There's a drainage ditch along one side
that kids can fall into. This tunnel is the
worst in Boulder.

Riding north across Valmont, a car
stopped right on the raised crosswalk as I
was about to enter it. To avoid hitting the
car I slammed on the brakes and slid on
loose gravel left over from ice/snow control

As a pedestrian, I was struck in the
crosswalk with a walk signal by a SB car
on 15th street who was turning right onto
WB Canyon Blvd. The driver was at a red
light and looking left for an opening in
vehicle traffic, and did not see me enter
the crosswalk (I was traveling EB through
crosswalk).
I believe that a contributing factor is that
the pedestrian traffic along Canyon Blvd is
set back further from the street than the
other sidewalks, so a driver may not notice
approaching pedestrians until they are
already to the corner.

1900 15th Street 40.01771001 -105.2757221 Other traffic safety

Throughout central Boulder, bicyclists
ignore red light signals and stop signs,
significantly increasing the chance of being
hit by a car or hitting a pedestrian. I see
this happen every day when I am in
downtown Boulder. Boulder needs a high
visibility education campaign to change
behaviors and help everyone understand
our responsibility to follow the rules to
keep everyone safe. Perhaps a bicycle
licensing program that requires safety
training would help. Bicycle safety required
every year in school including videos and
photos of injuries and interviews with
people whose lives have changed from
injuries would help as well. Increased
enforcement might help as well. Note this
problem is not just a few wild teenagers.
I’ve seen parents do this while riding with
their kids.

There's a median in the center of the road

Due to the high speeds of traffic and four

I was hit by a car while on my bike at this

I've also been intimidated by motorists

I've seen that happen to another

headed south, probably to make the green

4th is a popular route for walkers, runner,

a Broadway bypass and it gets dangerous,

!!! This is probably not City, but what is up

This path, if it connects to the Creek path,

Eventually, habitual drivers and cyclists will
be aware of this crosswalk in the middle of

The signal at this intersection frequently
fails to switch when someone presses the

east-west direction and about to change. It
will flash red in the E-W direction then go
back to green E-W and the light doesn't
cycle. This is right by the bike park and
families with kids ride here all the time.
The light cycle is hostile to the needs of
cyclists or pedestrians, advantaging cars
on Valmont over everything else. When I
called traffic engineering about this, they
told me it's because the signals are timed.
I don't care about the minor inconvenience
to cars. I care about the number of kids I
see riding across the red every single day,
dangerously crossing Valmont because
the signal never seems to change for
them.

I appreciate the Vision Zero focus on this

frequently vehicles don't actually slow

These connections to Dartmouth need to
be wider and less angular so that bikes
and peds are not in conflict and so that
bikes can navigate the turns. This is an
important connection for both bikes and
peds, so it should be designed to serve
both. Lots of kids access Creekside by
bike through this connection over the
footbridge to the south.

I use this stretch along Broadway between

Trim to two lanes and add noise reduction

INSANE speeds on cars zipping through
here. During rush hour, three lanes are
mostly empty, even at a rush hour stop
light, no more than 2-3 cars each lane
usually piles up. The wide, uncrowded 3

race up to 60+mph. and motorcyclists well
over 80mph. Living a block away from the

South Boulder Speedway?
This stretch of broad ways is louder than

Broadway is 6 lanes here, there is no need
for that. It just encourages cars to go even
faster. Speed limit is 40 I believe, but
everyone does 60, some go 75mph+. It's
louder than living next to a highway, and if
you close your eyes, it sounds like living
next to a racetrack, even from 2 blocks
back from the road. This section should be
trimmed to 4 lanes, plant trees and bushes
on the borders to dampen sound for the
neighborhoods and speed limit should be
30. It's obnoxious and it's disgusting this is
allowed in a residential area that has no
need for 6 lanes and high speeds. It has
never once been congested in years, and
the traffic is sparse enough for 4 lanes to
be plenty.

Turning onto EB Baseline from SB Inca
Pkwy is rarely easy due to the vehicle
volume and high speed of vehicle traffic on
Baseline. There is also high foot and
bicycle traffic in this area, and Inca Pkwy
slopes up to Baseline, so you must choose
your moment carefully and accelerate
rapidly.

Our house backs to Jay Rd. We frequently

The automated flashing lights are much
worse than nothing at all. When walking,
they often flash when I'm not ready to
cross or don't flash at all, forcing
interactions with drivers I'd rather avoid.
When driving, they're so often flashing
when there's nobody in sight or not
flashing when someone is crossing that I'm
trained to ignore them. I've almost hit a
child on a bike who didn't slow down or
look when entering the intersection,
presumably because he expected the
lights to keep him safe, when I didn't have
time to anticipate him crossing because he
approached the intersection so quickly. I
was able to stop in time, but the traffic
controls should aim to avoid this type of
interaction. In this case, they encourage it.

1390 Lehigh Street 39.97521268 -105.2601385 I feel unsafe walking

The reconfigured Lehigh included no traffic
calming features, so with the smooth
repaved road cars speed through here
even faster than before and often do not
stop for pedestrians at this and other
crossings. Central islands with xeriscape
or raised crosswalks (like on 55th) at
Darley and Emerson would have been
better for traffic calming. Perhaps the
raised crosswalks could still be added?
These are not as jarring as speed bumps,
but serve the same purpose as well as
making the crossing more noticeable and
therefore safer for pedestrians including
children headed to the nearby schools.
390 Linden Avenue 40.04078662 -105.2912951 I feel unsafe walking

Please help us! We have 12 children
Chase Court that use this intersection and
they lives are at risk. Coming off the bike
path (southbound) onto Moorhead is a
death waiting to happen. There are cars
parked along the road obscuring the view
of the bikes and pedestrians trying to cross
in the crosswalk. The "no parking" zone is
so small, the cars that are legally parked
still obscure the view for both drivers and
pedestrians trying to look for cars. You
literally have to get into the bike lane on
Moorhead in order to see a car coming
and for them to see you. No cars can see
my children or wheelchair bound people
because of this. And no one stops for us
hardly ever. This intersection needs more
flash to alert drivers (many of whom are

parking zone for drivers ability to see
pedestrians entry onto the Moorhead/bear
creek path crosswalk. We have instructed

Northbound cars on 19th cannot
adequately see the Norwood intersection

have a stop sign and I'm sure the city
thinks they should not have stop sign
because of the steepness. But that puts
cyclists and pedestrians crossing on
Norwood in jeopardy. Much like Linden

convenience of drivers over the safety of
vulnerable users. I don't buy the argument
that the cars might slip downward on
snowy days. This is supposed to be a safe-
routes-to-school zone. Peds first!
2801 Palo Parkway 40.04366552 -105.2585077 I feel unsafe driving
here
We need a left turn arrow (solid green, not
blinking yellow) on the signal for
northbound cars turning into Winding Trail
Village. It is a very dangerous turn when
southbound traffic on Hwy 36 is heavy
and/or moving fast, often running the light.
This leaves residents waiting in the turn
pocket vulnerable and at risk when trying
to get home.
Pawnee Drive 39.9963057 -105.2364492 I feel unsafe walking
here
This intersection has a lot of people driving
quickly through. It makes it difficult to
cross to get to the park.
Boulder Creek Park 40.01965742 -105.235945 I feel unsafe bicycling
here
There's a steep hill leading to a blind curve
on the approach to this tunnel, and the
landscaping sprinklers have turned it into a
perpetually flooded mess in warm months,
and a frozen sheet of ice in cold months.
Other Streets
Boulder Creek Path 40.0195049 -105.2359557 I feel unsafe walking
here
This is a narrow, blind curve on a path
that's always, always filled with puddles
and slick moss because it's always wet
from sprinklers. As you can see people
can't see oncoming bikes well and cross
the line to avoid the slippery puddles.
Many near misses between bikes and
peds here.
Boulder Creek Path 40.01976195 -105.2367336 I feel unsafe walking
here
The map shows a path here but there is no
legal crossing for the railway right of way
here. People do walk through the bushes
and across the tracks but there's no road
as shown in the map.
Boulder Creek Path 40.01987875 -105.2359289 Other traffic safety
concern
Property owners of the businesses north of
this tunnel overwater their lawn and create
flooding conditions and a mosquito
nuisance throughout the non-freezing
months. The water problem is exacerbated
by the growth of slippery mold inside the
tunnel where water pools, creating hazards
for peds and bikes. A lot of peds use this
tunnel, especially staff from BCH, who
walk here in groups. This has been an
ongoing problem for at least 15 years and
no amount of reporting to the city or
complaining to the property owners has
had any effect.
Other Streets
4810 Pennsylvania Avenue 40.00715081 -105.2347273 I feel unsafe bicycling
here
I fear for the safety of bicyclists and this
busy intersection between the bike path
and the road. Visibility of the bike path
from the road is obstructed in both
directions by foliage. Even when drivers
slow down significantly, it is difficult to see
bicyclists especially when they are
traveling at high speeds.
5262 Pennsylvania Avenue 40.00636425 -105.2308574 I feel unsafe walking
here
Not officially part of the city so residents
don't shovel snow on this street. It's
plowed for the school buses, so peds and
kids on bikes have to use the street not the
sidewalk.
2642 Pine Street 40.02401598 -105.2607125 I feel unsafe walking
here
Excessive car speeds and no markings or
infrastructure for crossing Pine St safely
between Folsom and 28th.
437 Pine Street 40.01847826 -105.2904904 Other traffic safety
concern
Concerned with cars speeding here. This
block has a number of children under 12
who are constantly playing in the yards.
We observe cars going above 30 here
pretty regularly as there are no stop signs
between 4th and 9th.
Speed bumps on spruce and on 4th very
nearby are effective at slowing cars down
on similar stretches with no stop signs. I’d
love to see one go in on Pine as well
Other Streets
1600 Quince Avenue 40.04789534 -105.277015 I feel unsafe driving
here
Barriers create single lane. Along with
many parked cars and service vehicles
frequently found on the highly used cross
street; Passing cars get too close to each
other; Also witness vehicles speeding up
to 'beat' the car approaching in the
opposite direction.
4176 Saint Croix Street 40.05097845 -105.2509169 I feel unsafe bicycling
here Jay is insanely dangerous
4446 Saint John's Avenue 40.04745229 -105.246202 I feel unsafe walking
here
Speed limit is 20, but cars are driving 45 in
this neighborhood. Pretty unsafe for folks
walking and especially kids biking.
295 Seminole Drive 39.99313374 -105.2308381 I feel unsafe walking
here
non ADA compliant overpass. should
move this to Foothills and Baseline with
possible underpass and fix the flood issues
to all the downstream neighborhoods at
same time
295 Seminole Drive 39.99320772 -105.2309883 I feel unsafe bicycling
here
Very steep overpass, no visibility to what's
ahead, hard to see if there are vehicles
approaching
2879 Shadow Creek Drive 40.01090218 -105.2562332 I feel unsafe bicycling
here
Very dark at night, with short visibility
under the best of circumstances.
Other Streets
5660 Sioux Drive 39.99301045 -105.2242666 I feel unsafe bicycling
here
This curve needs a curb cut and short
concrete path connector so that cyclists
traveling between the Rec center and
points East can meet up with the bike path
in a convenient and safe manner.
Currently you have to either turn in to the
rec center parking lot and get up on the
narrower pedestrian sidewalk, ride over
the curb and grass, or go out of your way
up to Omaha Place and back down
another narrow sidewalk. There is no safe
bike path connection and bikes should not
have to ride on the sidewalks to get to the
great path that lies just to the west of here.
4950 Sioux Drive 39.99322062 -105.2326947 I feel unsafe bicycling
here
This bridge is extraordinarily Steep and
dangerous in any kind of wet or cold
weather. It is not obvious to cars and they
often do not see cyclists.
5190 South Boulder Road 39.98585901 -105.2290571 I feel unsafe walking
here
Need better road crossing, rampant
jaywalking here for hotel + condo residents
and guests to get to PDQ and liquor store
5180 South Boulder Road 39.98636046 -105.2303025 I feel unsafe bicycling
here
Cars that are taking a left sometimes need
to immediately merge to the right here
making it dangerous for biking
5180 South Boulder Road 39.98631936 -105.2301943 I feel unsafe bicycling
here
Very dangerous stretch with many cars
missing the entrance to foothills from 36
and thus making a left and then a right
immediately.
Other Streets
5691 South Boulder Road 39.98598234 -105.2206832 I feel unsafe driving
here
It is very dark on this road - at night, the
only illumination are oncoming headlights
from the other side of the road. Could
really use a bit of street lighting from here
west
2357 Spotswood Place 40.05226863 -105.2665275 I feel unsafe bicycling
here
Path connection is very narrow for bikes
and pedestrians to share. Curb ramps are
also not build to ADA standards
2437 Spruce Street 40.02222644 -105.2637442 Other traffic safety
concern
Cars turning from Folsom Westbound onto
Spruce Street often speed, which is
hazardous for pedestrian traffic around the
park and for residents pulling out of their
driveways. I wish there was a speed bump
on Spruce across from Greenleaf Park.
2495 Spruce Street 40.02244405 -105.263316 I feel unsafe driving
here
Just a cluster here. Between the ped
crossing and merging to one lane folks just
don't pay enough attention. I support the
separated bike lane but the merge and the
ped crossing need to be separated
geographically. Move the merge south of
Pearl and make the right lane a turn-only
lane.
2307 Spruce Street 40.02190858 -105.2658033 I feel unsafe bicycling
here
Despite the posted 20 mph limit, vehicles
constantly speed through this section. The
pavement is also quite rough in the bike
lanes on this section of Spruce. It would be
helpful to have a more comfortable
east/west route downtown that connects to
Folsom.
Other Streets
1802 Spruce Street 40.02052825 -105.2724606 I feel unsafe bicycling
here
"Roundabouts" are improperly used by
motorists much of the time, with vehicles
on the east/west route not yielding and
blasting through. The diameter is too small
to slow traffic sufficiently.
2653 Spruce Street 40.02309148 -105.2602136 I feel unsafe walking
here
No sidewalks on North side of road and
this street gets traffic. Several blocks
around this area have no safe place for a
pedestrian to walk.
2052 Spruce Street 40.02134166 -105.2685392 I feel unsafe bicycling
here
The pinch point for pedestrian crossings is
painted to prioritize vehicle traffic, while the
bike lanes in both directions just end right
into the curb/parked cars, forcing cyclists
to merge into the primary lane. I've
frequently been passed by cars right as I'm
trying to move over. Since this is a vision
zero street and a school zone, we should
have the bike lane painted to have priority
for the merge zone, or some other
configuration that doesn't result in the bike
lane just disappearing.
Chautauqua Park 40.00028852 -105.2634484 I feel unsafe bicycling
here
Drivers merging from Baseline onto
Broadway don’t slow down or yield for
bikes and pedestrians in the crosswalk
here.
2805 Sundown Lane 40.01075786 -105.2579069 I feel unsafe walking
here
There are often encampments of
homeless in this area. Tents parked right
on the public seating areas and bicycle
chop shops.
Other Streets
2525 Taft Drive 40.01054883 -105.2619731 I feel unsafe walking

A lot of speeding cars between Folsom
and Taft year round. Carillon is assisted
living and the speeding (as a cut through
to 36) is definitely an issue.
2510 Taft Drive 40.01088986 -105.2630192 Other traffic safety
concern
Parking around this bend narrows the
street quite a bit and prevents East bound
cars from seeing oncoming traffic. This
one parking spot also has the potential to
cause damage to the car parked there due
to how it sticks out into traffic.

should be enforced there.
1505 University Avenue 40.0104373 -105.2735656 I feel unsafe bicycling

From Arapahoe to Iris, there are no great
options for crossing 28th, either as a
pedestrian or cyclist.
Even with the walk signal, it feels as
though you're dodging cars and distracted
drivers.
1101 Walnut Street 40.016588 -105.2809203 I feel unsafe walking
here
The entire "downtown loop" makes me
nervous every time I cross it because it
seems to prioritize fast through car traffic
in a busy pedestrian zone. The
intersection of Walnut and 11th is a
particular problem because pedestrian
traffic is high, visibility is poor, and drivers
coming southbound on 11th are given a
big, swooping turn that they can speed
through, potentially hitting someone
crossing the street.
2900 Walnut Street 40.0203516 -105.2544415 I feel unsafe bicycling

marking the bike lane is so worn away it's
basically invisible.
3000 Walnut Street 40.02011845 -105.253492 I feel unsafe driving

The right turn arrow is too short, and
there's no turn on a red arrow, so there's
only a very short window to turn right from
Walnut onto northbound 30th and a
looooong wait. As a result, people cut
through the Walnut Gardens parking lot
instead.

Boulder Vision Zero
Phase 2 Outreach Summary
Phase 2 Methods
City staff implemented a second phase of public outreach in February 2023. This second phase of
outreach consisted of:
• A virtual public meeting on February 7, 2023 (Spanish interpretation was offered)
See attached public meeting slides
• Preparation and posting (on bouldercolorado.gov/projects/vision-zero-action-plan) of a one-
page plan summary in English and Spanish
See attached one-page plan summary
• Preparation and posting (on bouldercolorado.gov/projects/vision-zero-action-plan) of short,
approximately five-minute, plan summary videos in English and Spanish
• A short, online questionnaire (in English and Spanish) with the following questions:
o What do you think about the Vision Zero Action Plan?
o What do you like best about the proposed actions and recommendations?
o What recommendations should staff prioritize for implementation?
• Office hours with city staff
• Lastly, staff presented the draft plan to the Transportation Advisory Board, Community Cycles,
and the Center for People with Disabilities to solicit their feedback
Office Hours & Online Questionnaire Responses
The public provided feedback on the draft plan by attending city staff office hours or by completing a
project questionnaire hosted on the city’s BeHeard Boulder engagement platform (open from January
20 through March 13). Feedback received focused on respondent’s feelings about the plan, what they
liked best about the plan and what they wanted staff to prioritize as the plan was implemented.
Many respondents to the questionnaire had mixed feelings about the plan (46% of respondents), while
others liked (31%) or didn’t like (23%) the plan. Respondents wanted to lower vehicles speeds; provide
safer travel through more protection for those walking, biking, and driving; increase enforcement; and
have more action taken sooner to achieve Vision Zero. Respondents also pointed to the importance of
routine maintenance of sidewalks and roadways, elimination of right-turn slip lanes, traffic signal timing
that supports more vehicular flow and reduced visual clutter to achieving Vision Zero.

We developed the Vision Zero Action Plan by
incorporating:
Phase 1 Community Engagement
700 surveys and Web map comments provided through BeHeardBoulder
37%of respondents had either been or knew someone who had been
seriously injured or killed in a traffic crash
The top 4 traffic safety concerns among respondents:
distracted driving, drivers not yielding to pedestrians or bicyclists, speeding,
and drivers and bicyclists not sharing the road
66%of respondents stated that traffic safety affects whether they walk,
bike, take transit, or drive
The top corridors that respondents were
concerned about: Broadway/South Broadway, Table Mesa
Drive/South Boulder Road, Arapahoe Avenue, and 28th Street
How We Developed the 2023-2027 Plan
New analysis to identify locations
with the most risk for crashes, the High
Risk Network, and proactive ways of
eliminating crashes
We developed the Vision Zero Action Plan by
incorporating:
Systemic Safety Analysis
•Analyzing historic crash data alone
leads to managing risk only at certain
locations
•Systemic Safety evaluates risk
across the entire roadway system
•This approach shifts from reactive to
proactive crash reduction strategies
Top 6 Risk Factors
•Business and mixed-use
zoning districts
•Higher traffic volume streets
•Signalized intersections
•Busier intersections without a
traffic light
•Streets with a multi-use path
•Higher speed streets
Core Arterial Network Corridors
Elevating work on a connected
system of corridors to meet
Boulder’s transportation goals:
•Protected bike lanes, intersection
enhancements, pedestrian
facilities, transit facility upgrades
•Reduce potential for severe
crashes
•Make travel more comfortable
and convenient
Project Identification
Along each of the High Risk
Network corridors, we identified
possible solutions based on:
•Engineer’s review of crash
data (5 years)
•Highway Safety Manual
analysis
•BeHeardBoulder feedback
How We Developed the 2023-2027 Plan
Racial Equity Index
•% of the population that are people of
color
•% of the population that are
Hispanic/Latino
•Median income
•% of the population below the poverty line
•% of the population enrolled in Housing &
Human Services financial aid programs

One-Page Plan Summary
How We Developed the
Vision Zero Action Plan
The city developed the 2023-2027 Vision Zero Action Plan by
incorporating:
• Successes and lessons learned from the prior plan to make the
new Vision Zero Action Plan more specific and actionable
•The city's 2022 Safe Streets Report, which analyzed crash data and
trends
• Community engagement in summer and fall 2022, including a
virtual open house, online survey and web map that received over
700 unique responses
• New analysis to proactively identify locations with the most risk
for crashes
• Prioritization of a project list that accounts for project safety
benefit, racial equity, and community engagement feedback
What is the Vision Zero Action Plan?
The Vision Zero Action Plan identifies a prioritized list of actions
that the City of Boulder will take between 2023 and 2027 to reduce
severe crashes. The Plan builds on the successes of the last Vision
Zero Action Plan (2019-2021), which include:
•Changes at 46 intersections including traffic signal timing that
prioritizes pedestrians, left-turn arrows, and signing/markings
• Implemented “20 Is Plenty” speed limits on all residential streets
• Advanced a program to incorporate improvements like protected
bicycle lanes with annual pavement work
• Won almost $5 million in grant funding from state and
federal agencies that resulted in Safe Routes to School
improvements, pedestrian crossings, sidewalks, new traffic signals,
speed limit setting, and other street design upgrades
•Increased enforcement by installing red light cameras at three
intersections to address drivers running red lights

Vision Zero Action Plan
Recommendations
The city will implement Vision Zero in
four ways over the next five years:
1.Changing how a street is built or how it
operates (traffic lights, vehicle speeds, etc.)
• Focusing improvements on the 18 Boulder
corridors with the most risk
for crashes, the High Risk Network (map)
• Make changes to intersections and other
locations where the most common crash
types occur: red light running, left-turn
crashes, crashes at right-turn slip lanes,
right-turn on red crashes, other right-turn
crashes, and crashes at pedestrian
crossings
• Coordinating Vision Zero projects with
Boulder’s Core Arterial Network program,
which improves connectivity and safety on
key high-traffic routes
• Pursuing regional, state
and federal funding
• Updating design practices, guidelines and
policies
2.Pairing changes to streets with
education and enforcement
• Regular collaboration with the Boulder
Police Department regarding enforcement
of behaviors of concern (speeding,
traveling under the influence of alcohol or
drugs, and distracted driving)
• Deploying the photo radar van,
and supporting legislation to
enable its expanded use
• Expanding the use of red light cameras
• Implementing campaigns focusing on
behaviors of concern
3.Improving the city’s internal
Vision Zero practices
• Ensuring Vision Zero strategies are
included in all capital projects
• Participating in the national Vision Zero
Cities Network and other regional Vision
Zero collaboration
4.Improving Vision Zero data
and transparency
• Maintaining and updating
the crash dashboard
• Refining and improving the accuracy and
utility of crash documentation

From: Fehr & Peers
Subject: Draft Systemic Safety Analysis for Boulder Vision Zero Action Plan
DN18-0589.04
The purpose of this technical memorandum is to document the process used to complete a
Systemic Safety analysis of five years of crash data provided by the City of Boulder and to identify
trends and potential risk factors. With a set of risk factors, we will map overlapping risk factors
citywide to identify area of focus for more detailed crash analysis and countermeasure
identification.
Attachment A contains the Systemic Safety analysis matrices. The matrices summarize crash data
as provided by the City of Boulder from 2016 through 2020. The matrices are:
• All crashes
• KSI crashes (fatal or incapacitating injury)
• Bike crashes
• Bike KSI crashes
• Pedestrian crashes
• Pedestrian KSI crashes

High-level Findings
The purpose of developing the Systemic Safety matrices is to identify crash profiles of significance
and risk factors across the transportation system. In doing so, we generally look within individual
crash field (rows) and contextual variable (column) categories, looking for datapoints that
represent either a high overall number or high percentage of crashes.
Based on our review of the Systemic Safety analysis, we have the following high-level findings:
• Crash profiles of significance, according to the Systemic Safety matrices, generally align
with the findings of the Safe Streets Report, including bicycle and pedestrian crashes,
crashes involving people ages 15-29 and 65+, and left-turn crashes.
• Other profiles that standout but are more nuanced include bicyclist-involved crashes
where the bicyclist is riding against traffic or the driver is making a right-turn at signals or
at multi-use paths.
• In looking at all crashes, 9 PM through 3 AM is a time period to focus on. However, in just
looking bicycle and pedestrian crashes, daytime hours are the area of focus (6 AM to 6
PM for bicycle crashes, 9 AM to 9 PM for pedestrian crashes).
• The contextual data identifies some clear differences and informs potential risk factors.
Some of these potential risk factors likely overlap, so in mapping risk factors to identify
locations for further analysis, we may aim to select different categories of risk factors that
do not overlap significantly to provide differentiation.
o Near a signalized intersection, especially those with a maximum cycle length
great than 100 seconds (this also includes crosswalks at a traffic signal),
recognizing that longer cycle lengths correlate to larger intersections with higher
entering volumes.
o Near a major, unsignalized intersection (any unsignalized intersection where one
approach has multiple lanes approaching); minor unsignalized intersections are
also notable for pedestrian crashes.
o Both of the above overlap with principal arterials and minor arterials, though it
should be said there are a fair number of KSI crashes (including bicycle or
pedestrian KSI crashes) on smaller streets (three lanes or less, residential, etc.),
which is likely representative of the number of roadway miles that these streets
comprise.
o Locations with on-street bike lanes or no bike facility/shared lane.
o Crosswalk locations with signing/marking only or unmarked (in addition to
crosswalks at a traffic signal, as described above), which involve both pedestrians
and bicyclists.
o Locations where streetlights are not present.
o Near parks, bus stops, or alcohol serving establishments.
o Locations adjacent to business or mixed-use zone districts.
Devin Joslin September 9, 2022 Page 5 of 5
o Locations with higher speeds and more quick acceleration, according to Wejo
data.
o Locations where the daily traffic per lane is <5,000 vehicles per day per lane.
Based on these high level findings, Fehr & Peers recommends detailed review of the following risk
factors for determination of the final risk factors that will comprise the High Risk Network:
• Be Heard Boulder high-concern segments
• Wejo hard braking – high
• Wejo quick acceleration – high
• Wejo 85th percentile operating speeds >30 mph
• Daily traffic per lane 5,000-10,000 vehicles per lane per day
• Business and mixed-use zoning districts
• Nearby uses (parks, bus stops, alcohol serving establishments)
• Streetlight not present
• Unmarked and uncontrolled crossings
• Bicycle facility presence: on-street bike lane and no bike facility/shared lane
• Multi-use path present
• Signals with cycle length greater than 100 seconds
• Major unsignalized intersections
• Signalized intersections
• Principal and minor arterials
• Roadway type: 6+ lanes, 35 mph+ posted speeds
Fehr & Peers created a web-based GIS tool to facilitate the review of these risk factors:

Boulder Vision Zero Action Plan Intersection Crash Analysis Report

I. I NTRODUCTION
Vision Zero describes the City of Boulder’s goal to eliminate traffic-related fatalities and serious injuries.
At its core, this goal is inspired by the belief that traffic collisions are preventable, and even one fatality
is too many. To help achieve Vision Zero, Boulder has developed several iterations of Vision Zero
Action Plans. The updated Boulder Vision Zero Action Plan seeks to identify and prioritize tangible
safety improvements to the transportation network in the City of Boulder and provide a clear
methodology for implementing improvements throughout the city.
Purpose and Need
Safety improvement recommendations for the updated Boulder Vision Zero Action Plan are based on
analyses of the existing roadway network. First, systemic safety analysis was conducted throughout the
city to identify risk factors related to fatal and serious injury crashes and locations where those risk
factors are most prominent. Recommendations developed from the systemic analysis are often
applicable to several locations based on site characteristics. Systemic recommendations can be seen as
proactive or forward-looking since they do not rely on recent crash history to be warranted.
Second, intersection crash analyses were conducted at key locations within the city to assess the
magnitude and nature of the safety problem within the project limits. Additionally, intersection crash
analyses relate crash causality to several factors such as roadway geometrics, roadside features, traffic
control devices, traffic operations, driver behavior, and vehicle type. Review of crash history may
identify patterns that are not functions of risk factors present at the intersections. Recommendations
developed from the crash analysis are typically site specific but can have applications outside of the study
intersections.
This Intersection Crash Analysis Report summarizes the results of intersection crash analyses for the
Boulder Vision Zero Action Plan.
Study Area
Through consultation with City of Boulders staff, 29 signalized intersections were chosen for crash
analysis. Selected intersections often included at least one cross street on the Core Arterial Network
(CAN), and typically had several risk factors from the systemic safety analysis. Figure 1 displays the
location of all 29 study intersections.
Table 1 lists all 29 study intersections, including the major street, minor street, and average annual daily
traffic volume (AADT). Traffic volumes shown in the table are from 2017-2019.

II. M ETHODOLOGY
The goal of this crash analysis process is to determine the magnitude of and nature of existing
intersection safety problems using data-driven techniques and statistical analyses. Safety Performance
Functions were used to evaluate the magnitude of safety problems. Pattern Recognition and Diagnostic
techniques were used to assess the nature of safety problems.
Safety Performance Functions & Level of Service of Safety
The magnitude of existing intersection safety problems on highway segments was assessed using Safety
Performance Functions (SPFs). The SPF reflects the relationship between traffic exposure, measured in
average annual daily traffic (AADT), and crash frequency measured in crashes per year. The SPF models
provide an estimate of the expected crash frequency and severity for a range of AADT among similar
intersection types. Two kinds of SPFs were used: the first addresses the total crash frequency while the
second only considers the frequency of crashes involving an injury or fatality (severe crashes). These
SPFs aid in assessing the magnitude of existing intersection safety problems from the frequency and
severity standpoint.
Development of SPFs leads to the conceptual formulation of the Level of Service of Safety (LOSS). The
concept of level of service uses qualitative measures that characterize safety of a roadway segment in
reference to its expected performance. If the level of safety predicted by the SPF represents an
expectation of crash frequency at a specific level of AADT, selected percentiles within the frequency
distribution can be stratified to represent specific levels of safety relative to the expectation of the SPF.
LOSS I – Below 20th Percentile
• Indicates a low potential for crash reduction.
LOSS II – 20th Percentile to Mean
• Indicates a low to moderate potential for crash reduction.
LOSS III – Mean to 80th Percentile
• Indicates a moderate to high potential for crash reduction.
LOSS IV – Above 80th Percentile
• Indicates a high potential for crash reductions.
LOSS boundaries are calibrated by computing the 20th and the 80th percentiles using the Gamma
Distribution Probability Density Function. Gradual change in the degree of deviation of the LOSS
boundary line from the fitted model mean reflects the observed increase of variability in crash frequency
as AADT increases. This increase is consistent with a Gamma Distribution error structure.
LOSS reflects how the intersection is performing with respect to its expected crash frequency and
severity at a specific level of AADT. It only provides a crash frequency and severity comparison with the
expected norm. It does not provide any information related to the nature of the safety problem itself. If
the safety problem is present, LOSS will only describe its magnitude from the frequency and severity
standpoint.
Correcting for Regression to the Mean Bias
The average of several years of crash history of an intersection provides an estimate of what is likely to
be observed in the future. The precision of this estimate, however, can be improved by correcting for
the Regression to the Mean (RTM) bias. RTM phenomenon reflects the tendency for random event
occurrences, such as crashes, to move toward the average during an experiment or over time. For
instance, if an intersection exhibits unusually high or unusually low crash frequency in a particular year,
Boulder Vision Zero Action Plan Intersection Crash Analysis Report
Page 5
RTM bias recognizes that over the long run the true average is closer to the mean representing safety
performance of similar intersections.
The existence of the RTM bias has been long recognized and is now effectively addressed by using the
Empirical Bayes (EB) method. The EB method is based on combining the information contained in the
known crash history with information regarding the safety of similar intersection types using the
expected mean value and over-dispersion parameter associated with the SPF. EB corrected values of
frequency and severity of crashes are used in the SPF analysis to assess the magnitude of the existing
safety problems.
Direct Diagnostics
The crash history of study intersections was evaluated to identify patterns related to crash type,
severity, direction of travel, road conditions, time of day and behavioral attributes. The distribution of
crash types and causal factors from the crash history was compared to the distributions of data that was
used in the formation of SPFs for similar intersection types. Using the binomial distribution, each crash
type and factor was evaluated to determine if the frequency of occurrence at a study intersection was
significantly greater than the average frequency observed at similar intersections. Any crash type or
factor with at least five occurrences and exceeding the 95 percent confidence level of the binomial
distribution is considered a diagnostic pattern.
Data Collection
Crash History
Crash history data was collected from the City of Boulder for all crashes at or related to the study
intersections (generally all crashes within 250 feet of an intersection were included). At several study
locations, crashes occurred at driveways to businesses or parking lots located near the primary
intersection. Generally, these crashes were included in the intersection crash history if the occurred
upstream of the intersection (involved traffic units approaching the intersection versus departing from
the intersection).
Traffic Counts
Traffic counts from 2017-2019 were collected from the City of Boulder and were used to establish the
expected crash frequency for SPFs. Turning movement counts and K-Factors were used to convert
traffic counts from design hourly volume to AADT.
SPFs and Diagnostic Norms
The Vision Zero Suite software from DiExSys was used to develop SPF models and baseline values for
diagnostic pattern analyses. This software collects crash history from several agencies in Colorado to
develop a comprehensive database that can be used to calibrate SPF models and diagnostic norms for
several different intersection types based on geometric configuration, geographic setting, and traffic
control.
