Development of a Guardrail Location and Prioritization Program

Grants and Contracts Details


The procedure used by the KYTC to identify and prioritize locations in need of guardrail was originally developed by KTC and documented as part of Report KTC-89-39 titled "Warrants and Guidelines for Installation of Guardrail". Additional work was perfonned by KTC in 2001-2002 to create a database to document sites in need of guardrail based on the Roadside Design Guide and KYTC field data. The Guardrail Rating System Database presently contains approximately 2,000 sites. There is a need to update the existing database and incorporate improved reporting capabilities. Another research study by KTC developed a scheme for calculating the benefit-cost ratio for each safety improvement alternative and selected the optimum combination of alternatives based on a specified budget (UKTRP-83-l2, titled "User's Manual for Dynamic Programming for Highway Safety Improvement Program"). This prioritization process should be reviewed and updated to include recent benefit and cost factors. In addition, enhancements to the overall process could be achieved with improved linkage and interconnectivity with the existing roadway characteristics database (IDS) and the crash database (CRASH).
