Abstract:This evaluation assesses how the Federal Highway Administration's (FHWA's) investment in research on high friction surface treatments (HFSTs) and related activities impact the availability and quality of such research; awareness, knowledge, and attitudes toward HFSTs in the United States; adoption of HFSTs as a safety measure; and safety performance of HFSTs on the U.S. transportation system. Although measuring the effect of specific FHWA activities is difficult, this evaluation found evidence that FHWA improved awareness, knowledge, and attitudes toward HFSTs and expanded the breadth of HFST research and performance data available to States considering technology deployment. The findings suggest FHWA played a key role in accelerating the consideration of HFSTs as a topic of interest, facilitated the exchange of knowledge between States at differing levels of adoption, and helped influence States' deployment of HFSTs. Many States saw a decrease in roadway-departure crashes. While FHWA cannot claim direct responsibility for this reduction, their continued research and promotion of HFSTs have enhanced roadway safety in the United States.
