                Application of High-Friction Surface Treatment in Winter Road Conditions
**Publication Year:** 
            2019
    
        High Friction Surface Treatment (HFST) has been used widely across the US to treat road departure crashes at horizontal curves with wet road conditions as a contributing factor. However, South Dakota has five times more roadway departure crashes involving winter road conditions than wet road conditions, and discovered that HFST had not been tested as a treatment for this crash type. Moreover, one third of roadway departure crashes occur on horizontal curves, even though horizontal curves account for less than 10 percent of the system.
