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:

  • SWITRS Summary
  • DUI Crash Summary and Map
  • Weekly Crash Trends
  • SWITRS Query & Map
  • California Safety Performance Measure Target Setting
  • Crash Diagram
  • Safe Routes to School Map 
  • ATP Maps & Summary Data
  • Motorcycle Crash Map 



SWITRS Summary

The SWITRS Statewide Summary is a tool for accessing and mapping statewide crash and injury data from the California Statewide Integrated Traffic Records System (SWITRS). The following data can be queried and viewed in tables:

  • Fatal and injury crashes (overall);
  • Fatalities and injuries (overall);
  • Fatalities and injuries to pedestrians, bicyclists, motorcyclists, older adults and unrestrained vehicle passengers; and
  • Fatalities and injuries related to alcohol, drugs, distracted driving, and speeding.

Users may query cities or counties, and may view 3 or 5 years of the most recent data available. Data is updated quarterly.

Explore alcohol- and drug-related crash and injury trends, both statewide and in a county or city area.

Weekly Crash Trends

This tool can be used to visualize weekly fatal and injury crashes on state highways in California. The tool can be used to monitor the frequency and type of crashes that occur on a weekly basis for recent years.
