liiklusfooride

Liiklusfoorid, known in English as traffic lights, are signaling devices positioned at road intersections, pedestrian crossings, and other locations to control competing flows of traffic. They are essential for managing the movement of vehicles, cyclists, and pedestrians, enhancing safety, and improving traffic flow.

The primary function of a traffic light is to assign right-of-way to different streams of traffic at different times. This is typically achieved through a sequence of colored lights. The most common sequence includes red, yellow (or amber), and green. A red light indicates that traffic must stop before the intersection or crossing. A green light signifies that traffic facing the signal may proceed, provided it is safe to do so. A yellow light serves as a warning that the signal is about to change to red, and drivers should prepare to stop if it is safe, or clear the intersection if they have already entered it.

Traffic lights can vary in complexity, with some featuring additional signals such as arrows to indicate permitted turning movements, pedestrian signals (often depicting walking figures and standing figures), or even countdown timers. The timing of these signals is often controlled by sophisticated systems that can adapt to real-time traffic conditions, aiming to minimize delays and congestion. The development and implementation of traffic lights have significantly contributed to reducing the number and severity of road accidents caused by conflicting traffic movements.
