SafeTREC began assessing the usage of the California Statewide Integrated Traffic Records System (SWITRS) by state and local agencies in 2003 on a project funded by the California Office of Traffic Safety (OTS). Specifically, the project looked at the needs of agencies to geocode and map the collisions in an efficient and simple manner. The lack of expertise or capabilities at many agencies did not allow any geographic analysis of traffic collisions and resulted in exorbitant consulting expenses, redundancy of various efforts, technical difficulties, inaccuracy, and other problems. Further grants from OTS allowed SafeTREC to develop a geocoding methodology and apply it to SWITRS data statewide. In order to distribute the geocoded SWITRS data, a web-based data query and download application was developed with the ability to display pin maps in Google Maps. A second application was designed to provide a more map-centric experience with other types of data layers and spatial analysis capabilities typically seen in a Geographic Information System (GIS). The TIMS concept was subsequently formed to give these applications a common foundation and provide a framework for continued development in the future.

The data on the site is provided AS IS. Modifications of the data and coordinates for SWITRS collision locations may be updated at any time. Although we strive for the most accurate geocoded locations, we do not guarantee all coordinates are correct and you should always review your data based on your own needs. Also, this site will only provide access to SWITRS data available within the last 11 years.
