AGENDA TITLE:
Vision Zero Action Plan Update
PRESENTER(S):
Natalie Stiffler, Director of Transportation and Mobility
Valerie Watson, Deputy Director of Transportation and Mobility
Devin Joslin, Principal Traffic Engineer
EXECUTIVE SUMMARY
Vision Zero is Boulder’s goal to eliminate all severe crashes resulting in a fatality or serious injury.
Vision Zero is a priority of the Transportation Master Plan (TMP), and it also informs the city’s other
transportation plans and standards. The Citywide Strategic Plan includes Priority Actions in support of
achieving Vision Zero within the Sustainability, Equity, and Resiliency (SER) Framework goal area of
Safe.
This memorandum provides an update on implementation of the Boulder Vision Zero Action Plan, May
2023, which includes a five-year list of actions for the period 2023-2027. The Vision Zero Action Plan
is oriented towards the implementation of improvements across Boulder’s transportation system that will
reduce the seven common crash types, as well as address other location-specific safety issues. The most
recent update to the Action Plan is innovative in that it takes a Safe Systems Approach to transportation
safety, which is a proactive and human centered approach rather than the historical reactive approach
based solely on crash data. The plan prioritizes implementation along the High Risk Network (HRN)
then expands to other streets. The Vision Zero Action Plan includes four categories of actions to achieve
Vision Zero through 20 specific actions (and numerous sub actions) as outlined in the plan document.
This memo also specifically details current progress on expanding photo enforcement, which is one of
the key actions in the Vision Zero Action Plan.
This memorandum also provides the Transportation Advisory Board (TAB) with an update on citywide
crashes that occurred in 2023, including a summary of severe crashes, now that data for the year in full
is available since TAB was last updated in October 2023. Staff will discuss the severe crash trends in
more detail during the meeting.
VISION ZERO ACTION PLAN IMPLEMENTATION UPDATE
The Vision Zero Action Plan and other community engagement materials associated with its
development can be reviewed on the project webpage, available at this link: Vision Zero Action Plan.
As previously mentioned, the Vision Zero Action Plan contains 20 specific actions (and numerous sub
actions) divided into four categories. The four categories include:
04.08.24 TAB Agenda 7 - VZ Action Plan Update
Page 1 of 14
• Implement and improve engineering solutions to reduce fatal and serious injury crashes (9
actions)
• Pair engineering solutions with education and enforcement (6 actions)
• Improve the city’s internal Vision Zero practices (2 actions)
• Improve Vision Zero data and transparency (3 actions)
Through a comprehensive crash data analysis, seven common crash types that account for 62% of fatal
and serious injury crashes on the HRN were identified. Focusing on the HRN will have an outsized
impact on reducing fatal and serious injury crashes. For this reason, the actions within the Vision Zero
Action Plan rely on a systemic safety approach that aims to: focus on common crash types and effective
solutions; prioritize locations with the most risk; and proactively implement solutions across the
transportation system.
The 2024 staff work plan includes focusing on the following key actions (found in the Action Plan
document starting on Page 64):
• Speed limit setting and signing framework (Action 7)
• Pedestrian Crossing Treatment Installation Guidelines Update (Action 6)
• Signal Timing Practices Update (Actions 1.A.ii, 1.A.iii, 1.B.ii, 1.C.i, 5)
• Photo Enforcement Expansion (Actions 11, 12, 13)
• Right Turn Slip Lane Signing/Marking Changes (Actions 1.E.i, 1.E.ii)
• Green Conflict Markings along the High Risk Network (Action 1.D.i)
• Traffic Signal Upgrades (Actions 4, 8)
In December 2023, the United States Department of Transportation awarded the city with a monumental
$23 million Safe Streets and Roads for All (SS4A) grant. The city received an approximately $3.2
million Demonstration grant and an approximately $19.8 million Implementation grant. These funds will
significantly accelerate implementation of key actions to eliminate severe crashes. Projects will be in
design over 2024-2025 with implementation and construction phases occurring between 2026-2028. The
projects funded with the SS4A grant include the following and are shown in Figure 1:

PHOTO ENFORCEMENT EXPANSION UPDATE
The City of Boulder has had a photo enforcement program for 25 years. In that time, the program has
grown to include over 180 neighborhood photo radar van deployment locations, five full-time and two
part-time photo enforcement officers, two photo radar vans, and 11 red light running cameras.
Information about the city’s photo enforcement program can be found here: Photo Radar and Red Light
Camera Citations.
On December 7, 2023, City Council adopted Resolution 1342 to designate certain streets within the city
as automated vehicle identification corridors. This action was required to comply with state law.
Materials submitted to Council in support of the resolution, which designates both the city-owned and
state-owned corridors, can be found here:
• City Council Memo: Photo Enforcement Expansion Memo
04.08.24 TAB Agenda 7 - VZ Action Plan Update
Page 5 of 14
This press release contains information about the recent expansion of photo enforcement. On March 15,
2024, automated speed enforcement at the intersection of Broadway/Pine Street was activated. The
automated speed enforcement is being conducted for the northbound direction of Broadway using
functionality enabled within the existing red light running camera at this intersection. In accordance with
state law, there was a 30-day public notice period prior to activation on March 15, which began a 30-day
warning period. Citations will begin being issued on April 15, 2024.
In addition, two new red light running cameras are currently in the process of being installed at 28th
Street/Jay Road (southbound approach) and Canyon Boulevard/15th Street (westbound approach). The
new cameras are expected to be activated on April 1, 2024. Once activated, there will be a 30-day
warning period prior to citations being issued.
Staff are currently in the process of evaluating designated city-owned corridors to determine priority
locations for expanded deployment of the photo radar van. The Boulder Police Department recently
hired an additional photo enforcement officer and is currently in the process of acquiring an additional
photo radar van. In addition, the 2024 Police Department budget included funding for six new concrete
pads to facilitate deployment of the photo radar van along arterial corridors where there is no shoulder
available on which to park the van. The prioritized list of locations staff are currently developing will
determine where to install the concrete pads this year.
Staff are also evaluating and prioritizing designated state-owned corridors. For state-owned corridors,
staff are required to submit a request to conduct automated enforcement to the Colorado Department of
Transportation (CDOT). Automated enforcement activities cannot be conducted on a state highway until
CDOT has granted the city approval to do so, in accordance with Colorado Revised Statutes 42-4-110.5,
which was amended last year under SB 23-200. CDOT is expected to publish the implementation
guidelines related to automated enforcement on state highways in mid-April. At that time, staff can
begin to submit requests for priority state-owned corridors to CDOT for review. While the turnaround
time for CDOT review and approval is currently unknown, the city is taking steps to be prepared for
swift installation after approval is granted.
2023 SEVERE CRASH SUMMARY 1
In 2023, there were 1,698 total crashes and 58 severe crashes (3 fatal and 55 serious injury) citywide, as
shown on Attachment A. Compared to 2022, the total number of crashes in 2023 was down 80, the
number of serious injury crashes was up 7, and the number of fatal crashes was up 2. Most severe
crashes in 2023 occurred on either Principal Arterial (53%) or Minor Arterial (26%) roadways. Of the
58 severe crashes, the crash modes are summarized below:
• Vehicle involved with bicyclist = 16 severe crashes
• Vehicle involved with vehicle = 14 severe crashes
• Vehicle involved with pedestrian = 10 severe crashes
• Vehicle involved with motorcycle or scooter = 7 severe crashes
1 The crash data reported in this memorandum and its attachments comes from the City of Boulder’s Transportation and
Mobility 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.
04.08.24 TAB Agenda 7 - VZ Action Plan Update
Page 6 of 14
•Bicyclist involved 2 = 7 severe crashes (4 involved a solo bicyclist and 3 involved a bicyclist
involved with either a pedestrian, bicyclist, or e-scooter rider)
•Standup scooter 3 involved = 3 severe crashes
•Motorcyclist involved = 1 severe crash
The most common severe crash types in 2023 include pedestrian, bicycle, fixed object, right angle, and
approach turn. The most common locations where severe crashes occurred in 2023 were at signalized
intersections (40%) or along roadway or multi-use path segments (29%). The age of the at-fault
driver/roadway user varies, but most range from 20-29 (37%) or 65+ (23%).
Comparing the 2023 severe crash trends to the findings of the Safe Streets Report, 4th Edition 2022,
which analyzed crash data from 2018-2020 reveals the following:
•The areas of concern noted in the Safe Streets Report were crashes involving people walking,
bicycling, making left turns, speeding and older adults (65+). These generally align with the
most common severe crash types in 2023.
•The percentage of severe crashes occurring on Principal Arterial or Minor Arterial roadways in
2023 was up 12% compared to 2018-2020.
•The percentage of severe crashes involving:
o People walking decreased by 1% in 2023.
o People bicycling increased by 4% in 2023.
o People traveling under the influence of alcohol or drugs decreased 9% in 2023.
o People speeding decreased by 20% in 2023.
o People making left turns decreased by 1% in 2023.
o People ages 65 and older decreased by 5% in 2023.
o People ages 15-19 decreased by 9% in 2023.
o People ages 20-29 decreased by 13% in 2023.
o Distracted road users increased by 2% in 2023.
o People riding a motorcycle increased by 3% in 2023.
Within the Safe Streets Report, trends that increased or decreased by more than 5% were noted as being
significant. The above comparison illustrates the importance of Vision Zero Action Plan actions geared
toward addressing the High Risk Network first, then focusing on other streets. In addition, the
comparison shows that a significant decrease (5% or greater) was experienced in five compared
categories, while none of the compared categories experienced a significant increase.
Table 2 illustrates the annual total and severe crash rates per million vehicle miles traveled (VMT) from
2018-2022, which is the most recent year for which VMT data is available.
2 None of the severe crashes with either a vehicle involved with bicyclist or bicyclist involved BCycle shared e-bikes.
3 Two of the three crashes involved Lime shared e-scooters.

2022 1,778 49 1,047 1.6982 0.0468
The total crash rate per million VMT decreased approximately 30% in 2022 compared to 2018. The
severe crash rate per million VMT decreased approximately 12% in 2022 compared to 2018. These rates
indicate that despite the number of severe crashes remaining relatively steady, the rate at which they
occur relative to million VMT is decreasing.
One other way to calculate and compare crash rates is to consider the number of total and severe crashes
that occur compared to the population. Table 3 shows how Boulder compares to other cities along the
Front Range with populations over 100,000 people. Note that the rates are calculated based on 2022
crash data reported to the Department of Revenue and 2021 population data. Note that the total number
of crashes cited for Boulder in 2022 in Table 2 varies from Table 3. This is because Table 2 includes all
police reported crashes, which includes crashes police respond to on private property, as well as crashes
police respond to involving only bicycles or pedestrians. These crashes are not reported to the
Department of Revenue.

As can be seen in Table 3, Boulder has the second lowest crash rate per 100,000 population among the
10 Front Range cities that were compared. Among cities compared, Boulder had the fewest fatal crashes.
This indicates that while zero fatal and serious injury crashes remain the goal, Boulder is closer to

achieving zero than many other Front Range cities.
NEXT STEPS
Staff will continue to implement the Vision Zero Action Plan and keep TAB informed, as necessary, on
key actions and projects.
Staff will present an overview of Vision Zero activities to City Council on April 11, 2024.

Safe Streets and Roads for All
(SS4A) Grants
Rural
Safe Streets for Boulder: Systemic Safety Countermeasure
Implementation
Applicant: City of Boulder
Boulder, Colorado
SS4A Award: $23,032,000
Project Description
The City of Boulder, Colorado, is
awarded funds to address intersection
and corridor safety issues for pedestrians
and bicyclists. The project focuses on
three key problems: pedestrian safety at
marked, non-signalized crosswalks,
crashes affecting vulnerable road users
on priority arterial segments, and severe-
injury crashes at 6 key intersections.
To address these issues, the project will
implement safety best practices at 22
intersections in the City, including
installing leading pedestrian intervals,
rectangular rapid-flashing beacons, and
protected intersections. Project
components also include adding traffic
signals and retroreflective backplates,
constructing protected bike lanes and
bus lanes, completing missing segments
of an existing multi-use path, increasing
all-red clearance intervals, and
prohibiting right turns on red at key intersections. The project includes a demonstration activity
to study and address right-turn slip lanes across Boulder.
