The Rectangular Rapid Flash Beacon (RRFB) is a device using LED flashing beacons in combination with pedestrian warning signs, to provide a high-visibility strobe-like warning to drivers when pedestrians use a crosswalk. In general, RRFBs are a visual cue that pedestrians may begin crossing the roadway at any time. They are always accompanied by crosswalk markings and signs. According to a recent study by the National Highway Traffic Safety Administration, RRFBs were found to increase the effectiveness in causing drivers to yield to pedestrians from 0-26% to 72-96%. In summary, this was a two year study that focused on replacing traditional LED flashing beacons with the RRFBs in order to decrease the number of pedestrian fatalities caused by non-yielding drivers. The flashing pattern can be activated with pushbuttons or automated (e.g., video or infrared) pedestrian detection.
