foot traffic signal
Signals displaying or broadcasting changing commands to pedestrians, commonly at road intersections.
Foot traffic signals are lights, mechanical flags, audio speakers, or other forms of signage which display or broadcast dynamically changing commands to pedestrian traffic. The most common form is a pair of lights signaling pedestrians to walk or to stop at a road intersection.
The command is addressed to people traveling on foot. Audible indications are possible alongside or instead of visible lights.
A vehicle traffic signal addresses drivers. A fixed directional sign gives route guidance without the changing movement command of a pedestrian signal.
