Abstract

The Utah Local Technical Assistant Program (Utah LTAP) with assistance from the Utah Department of Transportation conducted over 18 Road Safety Audit (RSA’s) projects on existing roadways. The projects ranged from roads on minor rural collectors to major urban collectors as well as intersections and unpaved roads. Part of this research shows the lessons learned and the common recommendations for each type of facility.

After all the RSA projects were conducted a tool was developed to help quantify the risk for drivers and pedestrians on the roadway. The tool is able to analyze the risk before and after recommended safety improvements are made which helps show the benefit of each safety recommendation. When the tool is used on multiple roads in a network, decision makers can find the highest risk roads and concentrate their safety improvements on those roads.
