How High-Friction Surfacing Treatments Combined with Other Safety Hardware Installations Save Lives Globally

Safety innovations have been one of the leading factors in the decline of casualty rates in both the United Kingdom and the United States. It has been estimated that 53% of all fatal accidents are due to roadway departures. There are several reasons for roadway departures to occur. The four major reasons are roadway conditions, collision avoidance, vehicle failure, and driver error. At least three of these may be impacted by safety improvements within the road surface that can increase the coefficient of friction. By increasing this friction coefficient there is a reduced likelihood that a vehicle will leave the roadway. One proven safety method is the use high-friction surface treatments (HFST). The Kentucky Transportation Cabinet (KYTC) has implemented a 3-year statewide safety improvement program using HFST at selected high-incident horizontal curve locations to improve pavement friction and reduce roadway departure crashes. The first round of results from the KYTC HFST has concluded a total crash reduction of 69% from an annual rate of 6.18 to 1.92.
