Study Title: WRRSP: Wyoming Rural Road Safety Program

Abstract: SAFETEA-LU contains language indicating that State Department of Transportations (DOTs) will be required to address safety on local and rural roads. The Wyoming Local Technical Assistant Program (LTAP) coordinated an effort in cooperation with the Wyoming Department of Transportation (WYDOT) as well as Wyoming counties and cities to identify low cost safety improvements on high risk rural roads in Wyoming. In this project, safety techniques and methodologies were developed to identify and then rank high risk locations on these rural roads. This project is unique because of the high percentages of gravel roads at the local level in Wyoming. The evaluation procedure developed is based on historical crash records and field evaluations. Three Wyoming counties were included in the pilot study. The statewide implementation has begun in 2009. This report describes the findings and recommendations of this research study which is not only beneficial to Wyoming but also to those states interested in implementing a High Risk Rural Road (HRRR) Program.
