42 <br /> <br />Pedestrian Hybrid Beacon (PHB) <br />Pedestrian hybrid beacons (PHBs), including the High-intensity Activated Crosswalk <br />Beacon (HAWK), are a type of hybrid signal intended to allow pedestrians and bicyclists to <br />stop traffic to cross high-volume arterial streets. This type of signal may be considered at <br />locations where MUTCD traffic signal warrants are not met or as an alternative to a full <br />traffic signal where MUTCD traffic signal warrants are met. <br /> <br /> <br />Guidance <br />• This type of device should be considered for all arterial crossings if other <br />engineering measures are found inadequate to create safe crossings. <br />• The MUTCD recommends minimum volumes of 20 pedestrians or bicyclists an hour <br />for major street crossings (volumes exceeding 2,000 vehicles/hour). <br />• PHBs may also be used at locations which do not meet traffic signal warrants but <br />where assistance is needed for pedestrians or bicyclists to cross a high-volume <br />street. <br />Considerations <br />While this type of device is intended for pedestrians, it would be beneficial to retrofit it for <br />bicyclists as the City of Portland, Oregon has, using bicycle detection and bicycle signal <br />heads on major cycling networks. Depending upon the detection design, the agency <br />implementing these devices may have the option to provide different clearance intervals <br />for bicyclists and pedestrians. The provision of bicycle signal heads would require <br />permission to experiment from FHWA.
