Regional Crash Data

Analyzing Crashes in Our Region

The NCTCOG Safety Program annually calculates county level crash rates on limited access facilities for the NCTCOG 12-County Metropolitan Planning Area (MPA). County Level Crash Rate Maps display crash rates by county in comparison to the regional crash rate for that year. Counties that have a higher crash rate than the regional rate are shown in red, while counties with a rate below the regional crash rate are shown in green.
