Which statement about Pedestrian Hybrid Beacons is true?

The correct statement indicates that a pedestrian signal head is installed at each end of the marked crosswalk. This is an essential feature of Pedestrian Hybrid Beacons (PHBs), as it ensures visibility and communicates clear and understandable signals to pedestrians intending to cross the roadway. By having a signal head at each end, pedestrians can know when it is safe to cross regardless of their position relative to the beacon.

The inclusion of signal heads at both ends maximizes safety for pedestrians, as it provides clear guidance and enhances awareness among drivers. It also aligns with the purpose of PHBs, which is to improve pedestrian safety at crossings, especially in areas where traditional traffic signals may not be warranted.

This functionality emphasizes the importance of pedestrian visibility and communication in traffic operations, showcasing how engineering designs can effectively manage the interaction between vehicles and pedestrians.
