Crash Data Resources

The WisTransPortal contains a complete database of Wisconsin MV4000 Traffic Accident Extract data from 1994 through the current year. This database contains information on all reported 1 crashes in Wisconsin, including the location of each crash, vehicles involved, and general crash attributes. Personal data has been removed. A local repository of MV4000 crash report image files from 2000 to the current year is also available. The TOPS Lab maintains the crash database and image file repository for research purposes and as a service to the Wisconsin Department of Transportation (WisDOT).

1 A reportable crash is defined as a crash resulting in injury or death of any person, any damage to government-owned non-vehicle property to an apparent extent of $200 or more, or total damage to property owned by any one person to an apparent extent of $1000 or more. (This definition went into effect 1/1/96). It is important to note, however, that not all reportable crashes are reported. In order for a crash to be in the database, an MV4000 crash report must have been completed by a police officer.
