Pedestrian countdown timers are devices installed at crosswalks that display the remaining time for pedestrians to safely cross the street. These timers typically show a countdown in seconds, helping people gauge how much time they have left before the traffic signal changes. This feature is especially useful for those who may have difficulty judging the timing of traffic lights. The primary goal of pedestrian countdown timers is to enhance safety for walkers. By providing clear visual cues, they encourage pedestrians to make informed decisions about when to cross, reducing the risk of accidents and improving overall traffic flow in urban areas.
