High Friction Surface Treatment Decision-Making Criteria

Between the years of 2019 and 2023, there were 203,662 run-off-road (ROR) crashes in Missouri resulting in 1,983 fatalities and 9,428 severe injuries. One safety countermeasure used by state departments of transportation (DOT) to address ROR crashes is called a high friction surface treatment (HFST). The goal of this research project is to provide the Missouri Department of Transportation (MoDOT) with criteria to help proactively identify locations for potential friction treatment applications. An ideal situation would be to calculate the minimum friction at a given curve location and have a list of friction treatment options (e.g., HFST, superelevation adjustments, curve realignment, and others). These criteria would be incorporated into MoDOT’s Engineering Policy Guide (EPG).
