Pedestrian Safety Guide and Countermeasure Selection System
The progression of a PHB.
Pedestrian Hybrid Beacons (PHBs) can warn and control traffic at unsignalized locations and assist pedestrians in crossing a street or highway at a marked crosswalk. A PHB should be installed in conjunction with the following:
Unlike a traffic signal, the PHB rests in dark until a pedestrian activates it via pushbutton or other form of detection. When activated, the beacon displays a sequence of flashing and solid lights that indicate the pedestrian walk interval and when it is safe for drivers to proceed. A solid red light requires drivers to stop while pedestrians have the right-of-way to cross the street. The overhead beacon flashes red when the pedestrian signals display a flashing DONT WALK indication. Drivers may proceed if the crosswalk is clear.
The PHB is often considered for installation at locations where pedestrians need to cross and vehicle speeds or volumes are high, but traffic signal warrants are not met. These devices have been successfully used at school crossings, parks, senior centers, and other pedestrian crossings on multilane streets. PHBs are typically installed at the side of the road or on mast arms over midblock pedestrian crossings.
Pedestrian Hybrid Beacons are less expensive than a full traffic signal installation. The costs range from $21,000 to $128,000, with an average per unit cost of $57,680.
