Legend:
Green = action on track to be completed or completed
Gold = action underway but less than 50% completed
Gray = action not started
•The 2024 staff work plan focuses on the
following actions:
•Action 1 – signal timing practices
update; right turn slip lane
signing/marking; green conflict markings
on HRN
•Actions 4 & 8 – traffic signal upgrades
•Action 6 – pedestrian crossing treatment
installation guidelines update
•Action 7 – speed limit setting
SS4A Grant
•Demonstration Grant Award
o $3,200,000
•Implementation Grant Award
o $19,832,000
•Total Grant Award
o $23,032,000
•The grant will significantly accelerate
implementation of key actions to eliminate
severe crashes.
VZAP/HRN & CAN
•Locations with 5 or 6 Risk Factors as
identified through Systemic Safety analysis
o 7% of city streets; 35% of arterials
o 48% of fatal and serious injury crashes
o 56% of bicycle crashes
o 57% of pedestrian crashes
•Nearly all of CAN overlaps with the HRN,
including each of the three priority CAN
corridors (Baseline Rd, Iris Ave, Folsom St).
•CAN projects transform arterial streets with
enhanced multimodal infrastructure and
proven safety countermeasures.
Photo Enforcement Expansion Update
•Council adopted Resolution 1342 on
December 7, 2023.
•Automated speed enforcement at the
intersection of Broadway/Pine St was
activated on March 15, 2024.
•Red light running cameras were activated at
Canyon Blvd/15th St and 28th St/Jay Rd
earlier this month.
•Staff are in the process of prioritizing
additional corridors for deployment.
Next Steps
Vision Zero Action Plan
•Continue implementation 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.
•Prepare for SS4A grant-funded efforts that can begin
once IGA is executed.
Questions for TAB
1.What feedback does TAB have regarding progress on Vision Zero Action Plan
implementation?
2.Does TAB have any questions on the near-term VZAP activities for 2024?
