• Abstract:
  Traffic barriers are installed on roadsides and medians to shield motorists from hazardous o vehicles. Due to the important role played by traffic barriers in promoting safety, it is importa continuously assess their condition and performance. This study prioritized and ranked traff Wyoming’s highways for safety improvement by enhancing the height of barriers below reco thresholds. This was achieved by conducting a benefit-cost analysis to estimate the reductio would be gained by adjusting barrier heights. The analysis indicated that substantial benefits accrued if barrier heights are optimized. Traffic barriers on Wyoming’s highways were then r the estimated benefits. As part of the study, a safety evaluation was carried out to identify th factors of traffic barriers that impact crash severity. Finally, a condition assessment procedu the Barrier Condition Index (BCI) was used to demonstrate a new approach in the condition rating, and prioritization of traffic barriers.
