According to the latest data from the National Highway Traffic Safety Administration (NHTSA), an estimated 36,750 people died in motor vehicle crashes in 2018, a slight decrease of roughly 1.0 percent from the reported fatalities that occurred in 2017. While this decrease is an improvement, there is still much work to be done for ensuring safety on our roadways, especially for vulnerable road users like pedestrians and bicyclists. NHTSA estimates an increase of up to four percent and 10 percent, respectively, for pedestrian and bicycle fatalities in 2018.
Accessing crash data plays an important role in assessing the safety needs and concerns for people walking and biking in our communities. Explore the tools and links below for accessing California crash data and statistics.
Transportation Injury Mapping System (TIMS)
The Transportation Injury Mapping System (TIMS) has been developed by UC Berkeley 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:
- SWITRS Query & Map
- SWITRS GIS Map
- California Safety PM Target Setting
- Collision Diagram
- SRTS Map Viewer
- ATP Maps & Summary Data
- Motorcycle Collision Map
|SWITRS Query & Map
A basic tool for accessing fatal or injury collisions from the California Statewide Integrated Traffic Records System (SWITRS).
|SWITRS GIS Map
The SWITRS Geographic Information Systems (GIS) Map tool offers an interactive map with the capability of multiple tasks including Rank by Intersection, Collision Diagram, etc.
California Safety PM Target Setting Supporting Tool
The California Safety Performance Management (Safety PM) Target Setting Support Tool is based on FARS, SWITRS, and HPMS data.
The Collision Diagram tool allows users to generate an interactive collision diagram. The Collision Diagram is accessible through SWITRS GIS Map.
|Safe Routes to School (SRTS) Map Viewer
The Safe Routes to School (SRTS) Map Viewer provides a pedestrian and bicycle collision map within a half mile radius of public schools in California.
ATP Maps & Summary Data
The ATP Maps & Summary Data tool utilizes multiple collision maps to find pedestrian and bicycle collision hot spots and generates data summaries within specified project and/or community limits.
Motorcycle Collision Map
The Motorcycle Collision Map provides a simple means to explore motorcycle collisions in California by selected county and/or city.

California Office of Traffic Safety (OTS)
OTS Collision Rankings
The California Office of Traffic Safety (OTS) Collision 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.
