The Transportation Injury Mapping System (TIMS) is available to anyone with Internet access. It contains California collisions reported in the Statewide Integrated Traffic Records System (SWITRS)—all crashes reported by the California Highway Patrol. TIMS allows users to select characteristics of crashes from dozens of options, including pedestrian and bicycle crashes, and view maps and Google streetview images of crash locations.

Office of Traffic Safety Collision Rankings

The OTS Rankings were developed so that individual cities could compare their city’s traffic safety statistics to those of other cities with similar-sized populations. Cities could use these comparisons to see what areas they may have problems in and which they were doing well in. The results helped both cities and OTS identify emerging or on-going traffic safety problem areas in order to help plan how to combat the problems and help with the possibility of facilitating grants. In recent years, media, researchers and the public have taken an interest in the OTS Rankings. It should be noted that OTS rankings are only indicators of potential problems; there are many factors that may either understate or overstate a city/county ranking that must be evaluated based on local circumstances.
