Crash Mapping Analysis Tool (CMAT)

    Crash Mapping Analysis Tool (CMAT) is an easy to use software program which provides convenient access to Iowa crash data through a simple GIS (map) interface. CMAT and half-day training are availabe for free to cities, counties, state employess, consultants, researchers, and anyone else who wants to use crash data to make the roadways safer for the future. CMAT was developed by the Center for Transportation Research and Education at Iowa State University under the direction of the Office of Traffic & Safety at the Iowa Department of Transportation.

CMAT Version

    CMAT Version 3.6.0 (released November 2006) is the current software version. CMAT Version 3.7.0 has also been released to address a software conflict for law enforcement agencies who also use Location Tool or IMAT.
