Crash Data

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.

  • TIMS also has maps generated for selected each city in the state as well as each county's unincorporated areas, which were developed in partnership with Safe and Active Communities (SAC) Branch within the California Department of Public Health. Maps provide a visual depiction of schools, including school closures and school district boundaries, street-level pedestrian and bicycle crashes, school free and reduced price meal eligibility, and past state and federal Safe Routes to School grant awards. These can be used for Safe Routes to Schools applications and other purposes.
  • TIMS also has maps derived from the National Highway Traffic Safety Administration(NHTSA) Fatality Analysis Reporting System (FARS). TIMS is funded by a grant from the California Office of Traffic Safety (OTS) through the National Highway Traffic Safety Administration (NHTSA).

The following tools are currently available on TIMS:

  • SWITRS Query & Map
  • California Safety PM Target Setting
  • Collision Diagram
  • SRTS Map Viewer
  • ATP Maps & Summary Data
  • Motorcycle Collision Map

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.
