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:

  • NEW! SWITRS Summary
  • Weekly Crash Trends
  • SWITRS Query & Map
  • California Safety PM Target Setting
  • Crash Diagram
  • SRTS Map Viewer
  • 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.

Weekly Crash Trends

This dashboard features provisional weekly police-reported injury crashes on state highways in California. Data on the page is updated daily and can be used to monitor the frequency and type of crashes that occur in the weeks prior, during, and after California’s stay home order, which went into effect on March 19, 2020 in response to the COVID-19 pandemic.
