Safety Evaluation of Multiple Strategies at Stop-Controlled Intersections (Full and TECHBRIEF)

Category:

Description

This study evaluated multiple low-cost safety improvements at stop-controlled intersections that included basic signing and pavement markings. This strategy is intended to reduce the frequency and severity of crashes at stop-controlled intersections by alerting drivers approaching a stop-controlled intersection. The results indicate reductions for all crash types (i.e., total, fatal and injury, rear-end, right-angle, and nighttime crashes). The economic analysis results suggest that the multiple low-cost treatments at stop-controlled intersections, even with conservative assumptions on cost, service life, and the value of a statistical life, can be cost effective.
