• Crash Modification Factors / Crash Reduction Factors

    ​NCDOT maintains a list of the crash reduction factors that are to be used for all safety project submittals statewide. The list is updated regularly and reflects information from the FHWA Crash Modifications Factors Clearinghouse as well as the results of safety evaluations that have been conducted by NCDOT staff.

  • Crash Proportions

    ​NCDOT has tables that provide a breakdown of crashes by severity and crash type for each major road facility type. These can be used in conjunction with the predictive spreadsheets.
