2023

With an aging state population, it is crucial to understand the factors that contribute to road safety among adults aged 65 and older and identify at-risk neighborhoods for targeted interventions. In this context, this report analyzes fatal and serious injury (FSI) trends and patterns among aging road users, including older pedestrians and bicyclists, with a focus on identifying neighborhoods at risk for crashes based on senior FSI rates. 2178 census tracts (32.7%) were deemed as being potential at-risk neighborhoods, as they all exceeded the state average senior FSI rate of 120 per 100,...

Submitted by Lisa Peterson

UC Berkeley SafeTREC is inviting 12 California Tribes to apply for the next round of Tribal Transportation Safety Assessments (TTSAs), to be completed by September 30, 2023. TTSA studies will be based on the tribal communities' input about their transportation choices, challenges and opportunities, and can help tribal staff and leadership plan and prioritize safety improvements for all travel modes (walking, bicycling, transit, driving) on tribal roads and pathways, and on roads accessing tribal lands. Tribal staff can also use the TTSA reports in support of their funding applications....

Transportation Injury Mapping System (TIMS)

The Transportation Injury Mapping System (TIMS) has been developed by SafeTREC's GIS Program team to provide quick, easy and free access to California crash data that has been geo-coded to make it easy to map out crashes and even view the locations in Google Street View.

The following tools are currently available on TIMS:
