Case Study – Safety Opportunities in High Friction Surfacing

This “Safety Opportunities in High Friction Surfacing” publication states that roughly half of all fatal crashes occur at intersections or on horizontal curves. In horizontal curve crashes, it is often the case that the vehicle speed and curve geometry create a “friction demand” higher than what can be achieved with standard pavement surfaces. Intersection crashes often occur when driver error creates an unexpected need for increased friction demand to serve as a “speed countermeasure.” One low cost approach that has been shown to be effective in addressing high “friction demand” locations is the installation of a High Friction Surface Treatment (HFST).
