This report documents findings from analysis of traffic collision data from sites that display high collision rates only under wet pavement conditions. These sites were selected using Caltrans safety engineers’ field reports, Wet Table C “investigation required” locations, and a new approach called Continuous Risk Profile (CRP). The geometric features at the sites were studied via field visits and review of as-built plans. Rapid spatial changes (i.e., vertical and horizontal curve in short distance), narrower lane width, lack of median, and wider total freeway width were some of the...

California's Strategic Highway Safety Plan (SHSP) Crash Data Dashboard now provides access to tribal crash data
UC Berkeley SafeTREC's geocoding team recently worked in collaboration with the Native American Advisory Committee (NAAC) and the California Department of Transportation (Caltrans) to provide access to tribal crash data on the Strategic Highway Safety Plan (SHSP) Crash Data Dashboard. The tabs of the SHSP Crash Data Dashboard now allow all data to be filtered by whether a fatal or serious injury crash was within 5 miles of a tribal boundary.
