Installation of pedestrian hybrid beacons (PHB) and rectangular rapid flashing beacons (RRFB) are becoming more common across Montana. While PHB and RRFB aren't new to national transportation systems, MDT understands they may be new or unfamiliar to Montana's motorized and nonmotorized travelers. These traffic safety technologies make crossing roadways safer for pedestrians and a quicker process for motorists. They are two of the many possible tools used by MDT to achieve multimodal safety and mobility.
How to Use:
A PHB functions as a traffic light for pedestrians and bicyclists, with the purpose of increasing motorists' awareness of pedestrian crossings at uncontrolled marked crosswalk locations. They are distinct from traffic signals and constant flash warning beacons because they are only activated by pedestrians when needed.
A RRFB is intended to improve visibility at uncontrolled, marked crosswalks. They are placed under the pedestrian crossing sign on both sides of a crosswalk. If a pedestrian wishes to cross, they press a button and the RRFB flashes. As they cross, a motorist can easily see the flashing lights and yield to the pedestrian. RRFBs are being installed more and more around the state - particularly in urban areas. According to the Federal Highway Administration (FHWA), RRFBs can reduce crashes up to 47% and increase motorist yield rates up to 98% when installed appropriately and correctly.
