The goal of this research was to evaluate and estimate the effectiveness of flashing beacons at stop-controlled intersections as one of the strategies in the Evaluation of Low-Cost Safety Improvements Pooled Fund Study (ELCSI-PFS), Phase I.

This research provides Crash Reduction Factor (CRF) and economic analysis for the effectiveness of flashing beacons at stop controlled intersections strategy. The estimate of effectiveness for flashing beacons at stop-controlled intersections strategy was determined by conducting scientifically rigorous before-after evaluations at sites where this strategy was implemented in the United States.
