Vision Zero Task Force

Collision Landscape Analysis

February 28, 2017

Welcome!

What happened since our last Task Force meeting:

• City Council adopted the Vision Zero Resolution

• Applied for an OTS grant for a

Vision Zero Safety and Outreach Campaign

• Data analysis

Updated Schedule

October 2016: Introduction and Purpose (done)

November 2016: Guiding Principles (done)

February 2017: Data Analysis

March-April 2017: Collision Profiles

June 2017: Draft Actions, Engineering

June 2017: Draft Actions, Non-Engineering

August 2017: Draft Action Plan

Today’s Agenda

1. Review data analysisa. Trends

b. Location

c. Vulnerable populations

d. Behavior

2. Breakout discussion

3. Next steps

About the Data

Transportation Injury Mapping System (TIMS)

• Injury collisions only (not property damage)

• 2009 – 2013 (2014 and 2015 data is provisional)

• Does not include state highway facilities

• Only includes collisions within the City of Sacramento

Key Terms

• “KSI” = killed or severely injured

• “vehicle” includes motorcycle and truck, unless otherwise

stated

TRENDS

Disadvantaged communities account for ¼ of street

Disadvantaged Communities

CalEnviroScreen 2.0 Disadvantaged Communities are defined under Senate Bill 535 as the top 25% census tracts within the State of California with the highest CalEnviroScreen 2.0

score. The score takes into account indicators related to environmental exposure and effects, sensitive populations, and socioeconomic factors.

Breakout Discussion

• What was unexpected?

• Which findings do you think the community will find

most compelling?

• Which findings make you want to learn more?

• What follow-up questions do you have?
