| Summary: | The Kentucky Transportation Cabinet (KYTC) Highway Safety Improvement Program (HSIP) has been utilizing a data-driven high friction surface treatment (HFST) program as a proven safety countermeasure for wet weather and roadway departure crashes. This report will walk through the origins of the study and the process to identify candidate locations for HFST and development of a pavement friction program. The project has constructed over forty sites in 2023, including a mixture of rural corridor curves, signalized intersection approaches, and limited access freeway ramps. The project utilized a mixture of pavement friction data, pavement resurfacing lists, and specific crash data. The sites are being reviewed to show the benefits through a before and after crash analysis and pavement condition over time based on traffic volumes, weather, and other factors.
