Minnesota Crash Mapping Analysis Tool (MnCMAT2)

The (MnCMAT2) software enables the user to analyze crashes based on a large number of crash attributes, including: county, city, township, measure, intersection, and date ranges. The tool also enables the user to produce charts or maps to graphically view crash data and crash locations. Charts can be created by various crash attributes, including: crashes by county, month, day of the week, crash severity, manner of collision, surface conditions, and type of roadway. The software can produce a color map with plotted crashes and a series of charts or reports based on selected crash attributes.

MnCMAT2 contains a rolling 10 year dataset plus current year crash data as reported to Department of Public Safety.

Current data from 1/1/2011-6/30/2021. Crash data last updated on 7/9/2021

The tool is to be used by traffic safety professionals only.

Data issue resolved: There was a data error for crashes prior to 2016 in the following counties: Mahnomen, Marshall, Martin and McLeod. This error is corrected. Please contact Loren Hill with any questions at loren.hill@state.mn.us
