Collision-Related Maps and Injury Data

Transportation Injury Mapping System (TIMS)

TIMS is a web-based data query and download application developed to display pin maps in Google Maps, using the California Statewide Integrated Traffic Records System (SWITRS) collision data. A second application was designed and applied 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), which is all available to the public.
