Step-by-step explanation:
Pedestrian Activated Crosswalk Signals and Safety:
When a crosswalk is equipped with a pedestrian-activated signal that flashes, it signifies that drivers should be prepared to stop if pedestrians are present. This means that upon seeing the flashing lights, drivers should slow down and be ready to come to a full stop to allow pedestrians to cross safely. The installation of traffic signals at intersections intends to reduce the risk of accidents, particularly in areas with high pedestrian traffic such as near a school campus. It ensures that pedestrians can cross at appropriate times without having to dodge traffic, and it compels vehicles to adhere to the posted speed limits, therefore enhancing overall safety at the crosswalk.
