liiklusvalgus

Liiklusvalgus, also known as traffic lights, are signaling devices used to control the flow of traffic at intersections. They are typically composed of three colored lights: red, yellow, and green. The red light indicates that drivers must stop, the yellow light warns drivers to prepare to stop, and the green light allows drivers to proceed. Traffic lights are designed to improve traffic flow, reduce congestion, and enhance safety by regulating the movement of vehicles.

The operation of traffic lights is governed by a traffic signal controller, which can be programmed to adjust the timing of the lights based on various factors such as traffic volume, time of day, and weather conditions. Some advanced traffic light systems also incorporate sensors and cameras to detect the presence of vehicles and pedestrians, allowing for more dynamic and responsive control.

Traffic lights are commonly used in urban areas and on major roads to manage the flow of traffic and prevent accidents. They are an essential component of modern transportation infrastructure, helping to ensure the smooth and efficient movement of vehicles and pedestrians.
