Traffic lights, which may also be known as stoplights, traffic lamps, traffic signals, signal lights, robots or semaphores,are signalling devices positioned at road intersections, pedestrian crossings and other locations to control competing flows of traffic. Traffic lights were first installed in 1868 in London, England,[3] and are today used in almost every city of the world. Traffic lights alternate the right of way accorded to road users by displaying lights of a standard color (red, yellow/amber, and green) following a universal color code (and a precise sequence to enable comprehension by those who are color blind).
In the typical sequence of color phases:
- Illumination of the green light allows traffic to proceed in the direction denoted, if it is safe to do so
- Illumination of the orange/amber/yellow light denoting to prepare to stop short of the intersection (or keep going if not enough room to stop), if it is safe to do so
- Illumination of the red signal prohibits any and all traffic from proceeding
Usually, the red light contains some orange in its hue, and the green light contains some blue, for the benefit of people with red-green color blindness.
