How Traffic Crash Data is Collected

The Michigan State Police Criminal Justice Information Center (CJIC) and the Office of Highway Safety Planning, in conjunction with the University of Michigan Transportation Research Institute (UMTRI), compiles and publishes the annual Michigan Traffic Crash Facts.

Fatal records are maintained on both the state system and the federal Fatality Analysis Reporting System (FARS), which is supported by the National Highway Traffic Safety Administration (NHTSA). Traffic Crash Report data is also supplied to the Michigan Department of Transportation for analysis of high crash locations and to bill for damage to state property. The Michigan Department of Community Health receives data to bill the appropriate no-fault carrier for reimbursement of expenses under the Medicaid program, and the Michigan Department of Natural Resources receives data for analysis of snowmobile and car/deer crashes.
