Traffic Safety Evaluation of Pedestrians and Bicyclists at Rectangular Rapid Flashing Beacons and Pedestrian Hybrid Beacons in Minnesota

Status:  Complete
Report Date:  04/23/2024

Summary:

To improve the visibility and safety of pedestrian and bicyclist crossings, traffic-safety professionals across Minnesota have installed the Rectangular Rapid Flashing Beacon (RRFB) and Pedestrian Hybrid Beacon (PHB) at numerous locations around the state. The purpose of this evaluation was to determine the safety benefits, if any, for pedestrians and bicyclists after installation of an RRFB or PHB. This report included a before-after analysis as well as a cross-sectional analysis for each type of beacon with a corresponding group of comparison sites. The before-after analysis found that installation of an RRFB resulted in a 67% decrease in fatal crashes and a 62% decrease in bicyclist crashes. Installation of a PHB resulted in a 53% decrease in suspected minor injury crashes, a 67% decrease in pedestrians crashes, and a 50% decrease in bicyclist crashes. The results of the cross-sectional analysis did not indicate that these reductions were statistically significant compared to similar reductions in the control group. Still, the decreases in severe crashes and crashes involving non-motorists at RRFBs and PHBs indicated that both types of beacons could be effective safety treatments.
