Pedestrian Detection

An intersection treatment that relies on sensors to detect when a pedestrian is waiting at a crosswalk and automatically triggers the pedestrian “ WALK ” phase . Reduces crossings at inappropriate times while providing sufficient time for pedestrians to cross the roadway .

Pedestrian Hybrid Beacon

A pedestrian-hybrid beacon ( PHB ) is used at unsignalized intersections or mid-block crosswalks to notify oncoming motorists to stop with a series of red and yellow lights . Unlike a traffic signal , the PHB rests in dark until a pedestrian activates it via pushbutton or other form of detection .
