Informing the Selection of Countermeasures by Evaluating, Analyzing, and Diagnosing Contributing Factors that Lead to Crashes (BTS-14)

NOTE: This project is NCHRP 22-45. BTSCRP provided some funding since human behavior is a known factor contributing to many crashes. 

The objective of this research was to assess best practices in crash diagnosis across crash types in modal diverse contexts, recognizing that vehicle and mode mix matters in the success of investment strategies. The research team developed additional diagnostic tools that leverage the availability of crash, roadway, traffic volume, human factors, and behavioral, socioeconomic, and demographic data to advance the art of the practice in crash diagnostics that consider both modal priority and facility context.
