Crosswalk Rapid Flash Beacon

 

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.

 

 

 

 

 

Key Benefits of RRFBs: 

1. RRFBs are a lower cost alternative to traffic signals and hybrid signals.

2. RRFBs at pedestrian crosswalks are dramatically more effective at increasing driver yielding rates to pedestrians than traditional overhead beacons.(see study mentioned above)

3. RRFBs  stutter flash may elicit a greater response from drivers than traditional methods.
