Abstract:

According to the National Highway Traffic Safety Administration (NHTSA), a total of 32,675 people died in motor vehicle crashes on the U.S. highway system in the year 2014. In order to address this issue, transportation professionals have continued to investigate countermeasures to improve roadway safety. High friction surface treatments (HFSTs) have the potential to be a sustainable and cost-effective means of doing so. This pavement overlay system maximizes the existing infrastructure, and provides exceptional skid resistance where friction demand is critical, such as intersection approaches or horizontal curves. This research seeks to review the performance of HFSTs from a safety and economic perspective through an analysis of HFST installation projects in the state of Pennsylvania. Using data provided by the Pennsylvania Department of Transportation (PennDOT), it analyzes the extent of their effectiveness in reducing crash rates and crash severity through a before-after and benefit-cost study of over 70 sites. The results of these two investigations indicate that Pennsylvania received the greatest reduction in crash number and severity as well as the greatest return on investment for intersections on horizontal curves that are located in an urban environment. The results, along with further statistical analysis, will be used to develop crash modification factors and a safety performance function to quantify the expected crash reduction and the average number of crashes per year. The goal of this study is to enable DOTs to maximize return on investment and to better anticipate the safety benefits of HFSTs prior to implementing new projects.
