From 2016 through 2018, there were more than 19,200 vehicles in the United States involved in opposite direction crashes that resulted in a fatality. Approximately 68 percent of these crashes occurred on two-lane roadways.
The TRB National Cooperative Highway Research Program's NCHRP Research Report 995: Guidelines for Treatments to Mitigate Opposite Direction Crashes provides state departments of transportation (DOTs) practitioners and other transportation professionals with comprehensive guidelines for the selection of cost effective countermeasures to address opposite direction crashes.
Supplemental to the report is a guidance document for selecting countermeasures.
