Traffic lighting is the traffic control system responsible for the smooth movement of pedestrians and vehicles, aiming to ensure balanced service for all directions, increase traffic flow, and signal various points in private or public areas that require special attention from drivers.

Typical applications of traffic lighting include urban and interurban intersections, pedestrian crossings, railway crossings, toll stations, tunnels, parking areas, and more.

Traffic lighting consists of traffic lights equipped with incandescent, halogen, or LED lamps, traffic controllers, and various supplementary devices such as pedestrian push buttons, pedestrian and vehicle movement detectors, acoustic warning devices, and more.
