Abstract:The lack of pavement friction causes vehicles to skid and run off the road (ROR). In 2016, single-vehicle ROR crashes resulted in 1,293 deaths on Texas highways. The Texas Department of Transportation (TxDOT) Highway Safety Improvement Program evaluated the cost of one roadway fatality or one incapacitating injury at approximately $3.3 million. If building better skid-resistant pavement surfaces could reduce fatalities by 1 percent, the potential annual reduction in societal cost, given the number of ROR fatalities in 2016, would be significant.
