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.
Crash Contributing Factors
The Contributing Factor Analysis is done each year for serious injury and fatality crashes and includes Primary, Secondary, and Tertiary Contributing Factors on limited access facilities in NCTCOG's 12-county MPA.
