Crash Data for Local Agencies

Cities, counties, tribes, and other organizations often use crash data to identify, evaluate and prioritize safety enhancements at potential crash sites, in projects and when applying for grants. In Washington, a law enforcement officer investigates a crash occurring on a public roadway where there is more than $1,000 damage to property or a person is injured, a Police Traffic Collision Report (PTCR) is required. These reports are sent to the Washington State Patrol Collision Record Section that is embedded within WSDOT’s Transportation Data, GIS & Modeling Office. Raw data from the PTCR submitted to WSP’s Law Enforcement Database. WSDOT’s Crash Data and Reporting Branch analyzes all PTCR’s and adds additional safety and engineering information to the crash record which is stored in their statewide crash data repository. This data is available for every county and incorporated city within the state.
