San Mateo City Council
April 15, 2024
Question for Council

• Speed Management
• Leading Pedestrian Intervals
• Signal Visibility Enhancements
• No Right on Red treatment
• Centerline Hardening Treatment
2 Agenda
1. What is a Local Roadway Safety Plan?
2. LRSP vs Other Plans
3. Plan Development
4. Implementation and Monitoring
5. Next Steps
3 Framework for Safety
Improvements
Focus on all components and players
in roadway system
Understand mistakes will happen
and design a forgiving environment
Industry best practice approach for
roadway safety
Adopted by Caltrans and USDOT
4 What is a Local Roadway Safety Plan?
Analyzes historical crash patterns and trends
Prioritizes safety improvements based on crash data and stakeholder engagement
Identifies proven engineering and non-engineering strategies Meets federal safety plan guidance and Caltrans LRSP
requirements
5 LRSP vs Other Plans
6 Circulation Element
7 Goal C-1
Design and implement a multimodal transportation network Prioritizes walking, bicycling, and transit
Sustainable, safe, and accessible for all users
Connects the community using all modes of transportation Reduces vehicle miles traveled (VMT) per capita

LRSP vs Vision Zero Action Plan
Local Roadway Safety Plan
• Focuses on infrastructure improvements
• Works toward reducing fatal and severe injury
collisions
• Generally overseen by PW with input from
Safety Partners and community
Vision Zero Action Plan
• Reduce fatal and severe injury collisions by
a specific date
• Plan Development:
• CMO, Fire, PD, PW, and regional partners develop
actions to meet the goal
• Includes LRSP and Complete Streets Plan
recommendations
• Includes demographic-specific actions and
recommendations
• The Committee meets regularly following
adoption to identify actions that may be
needed to work toward the goal

36 Funding
Two site-specific projects already in the CIP:
Humboldt/Poplar Signal Modifications
Norfolk/Fashion Island Blvd Signal Modifications
Several other projects already completed or included in other planning efforts:
Peninsula Ave Bike Facilities
Hillsdale Blvd Improvements (Caltrans)
LPI installed ~10 years ago in Downtown
Site-Specific Projects and Systemic Treatments qualify for safety-related grant funds: SS4A and HSIP
37 Monitoring & Updating the Plan
Review crash data to track progress annually.
Revisit safety plan for broader updates every
three to five years.
Additional updates as determined with safety
partners due to new trends, technologies, or
strategies.
38 Next Steps
39 Adopt LRSP in
Spring/Summer
2024
1 Continue work on
projects already in
CIP
2 Seek grant funding
for identified projects
Request additional
CIP funding based on
identified priorities
