Community Maps - Wisconsin County TSC Crash Mapping

New Version Notification

Community Maps was upgraded to a new version on January 2, 2018. This version is automatically populated with crash data from the Wisconsin DT4000 police crash report database, a newly available source of accurate and timely crash locations. These crash locations are utilized at your county Traffic Safety Commission (TSC) meetings each quarter to review local crash trends and implement preventative countermeasures. They are also utilized at the state level for grant and resource allocation.

Enter Community Maps

Community Maps provides Wisconsin's local law enforcement and county Traffic Safety Commissions with an online interface for mapping crash data. Fatal crash locations are mapped from 2001 to the present. Severe injury crashes are mapped from 2012. Crashes are mapped through a combination of manual and automated processing. Community Maps uses the Google Maps API, which provides a familiar, high quality map interface.

Community Maps is hosted at the University of Wisconsin-Madison by the Wisconsin Traffic Operations and Safety (TOPS) Laboratory in collaboration with the Wisconsin Department of Transportation (WisDOT) Bureau of Transportation Safety (BOTS).
