Vision Zero Task Force February 28, 2017 Collision Landscape Analysis
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
1. Review data analysis a. Trends b. Location c. Vulnerable populations d. Behavior 2. Breakout discussion 3. Next steps Today s Agenda
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
All Collisions 519 collisions with victims killed or severely injured (KSI) between 2009 and 2013 non-ksi KSI
All Collisions 2,400 2,000 1,600 1,200 800 400 2009 2010 2011 2012 2013 truck motorcycle pedestrian bicycle auto
Over the same period of time, the number of collisions with victims killed or severely injured increased by 7%
KSI Collisions 120 100 80 60 40 20 2009 2010 2011 2012 2013 truck motorcycle pedestrian bicycle auto
KSI Collisions Auto Collisions Down 14% Bike Collisions Up 40% Pedestrian Collisions Up 57%
Pedestrian collisions account for 10% of all collisions, but 43% of fatal collisions
Fatal Collisions 35 30 25 20 15 10 5 2009 2010 2011 2012 2013 truck motorcycle pedestrian bicycle auto

The score takes into account indicators related to environmental exposure and effects, sensitive populations, and socioeconomic factors.
HIN in Disadvantaged Communities 38% of the HIN falls within disadvantaged communities

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?
