Abstract:HFST is a safety countermeasure intended to restore and maintain pavement friction in wet and dry conditions to reduce crashes. This treatment is especially effective where there is a history of wet-pavement crashes. In Pennsylvania, over 50% of the fatal and serious injury crashes involve a lane departure, and intersection crashes account for 21% of the annual fatalities and 30% of serious injuries with slippery and wet roads conditions often contribute to many of the fatal and serious injury crashes. This noteworthy practice highlight PennDOT's effort in reducing wet-pavement crashes at curves and intersections throughout the Commonwealth by installing high friction surface treatments (HFSTs) at strategic locations.
