• Abstract:
  When typical low-cost safety improvements, such as signing and delineation, do not reduce crashes, the Kentucky Transportation Cabinet’s (KYTC) options are limited. Narrow, winding roads are prevalent in Kentucky and lane widths less than 9 feet are not uncommon. In many instances roads have very little right-of-way, making more substantial treatments like shoulder installation very costly. While striping is a viable solution in some circumstances, the Manual on Uniform Traffic Control Devices (MUTCD) does not recommend installing center or edge line pavement markings for pavement widths under 20 feet. These challenges directed KYTC to look for alternative countermeasures to keep vehicles on the road coupled with an ability to be installed within a constrained right-of-way. High friction surface treatments (HFST) emerged as a potential alternative to address Kentucky’s issues.
