Flashing Beacons


There are multiple types of flashing beacons for use in different scenarios. Flashing beacons are used to warn drivers of speed limits, school crossings, sharp curves, and other situations where such cautions are warranted. Rectangular Rapid Flashing Beacons (RRFBs) or Pedestrian Hybrid Beacons (PHBs) can be used to enhance pedestrian crossings (especially at high visibility crosswalks) with high demand or vulnerable users.


    Effective in alerting drivers to stop.

    Enhanced cyclist and pedestrian safety.

    RRFBs can reduce pedestrian crashes by up to 47% and have yielding rates up to 98%.

    PHBs can reduce pedestrian crashes by up to 55% and have a 29% reduction in total crashes. Yielding rates are 96% and better


    Less effective if flashing 24/7.

    May give non-auto users a false sense of safety.

    Increased implementation and maintenance costs.

    Can lose enhanced effectiveness if used too often.

    Pedestrians may choose to not push the button and cross as they deem appropriate, conflicting with driver expectations.


    Midblock locations with high traffic volumes.

    School zones.

    Crossings with high bike and pedestrian usage.
