ABSTRACT
SAFETEA-LU states that Departments of Transportation (DOTs) agencies will be required to address safety on local and rural roads. It is important for state, county, and city officials to cooperate in producing prehensive safety plan to improve safety statewide. This legislation provides an opportunity to implement a more coordinated approach to local road safety in Wyoming. 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 all rural roadways in Wyoming. What makes this project unique is the high percentage of gravel roads, over 90%, at the local level in Wyoming. The evaluation procedure developed is based on historical crash record and field evaluations. The main objective of this research was to develop and evaluate transportation safety techniques that can help Wyoming agencies in reducing crashes and fatalities on rural roads state wide. Three Wyoming counties were included in the pilot study. Statewide implementation is expected at the beginning of 2009. This paper describes the findings and mendations of this research study which would be very beneficial to those states interested in implementing a High
