TRAFFIC SIGNALS Meaning and
Definition
-
Traffic signals are devices used to control the movement of vehicles and pedestrians at intersections or other locations where roadways intersect. Also known as traffic lights or stoplights, these are typically composed of three colored lights; red, yellow, and green, arranged vertically or horizontally. Each light color conveys a specific message and guides traffic accordingly.
The red light is used to indicate that vehicles and pedestrians must come to a complete stop. It signals an immediate halt and is associated with opposing traffic lights being green or yellow. The yellow light serves as a warning prior to the change from green to red, signaling drivers to clear the intersection or prepare to stop safely. The green light gives the go-ahead for traffic to proceed, indicating the right of way and allowing vehicles and pedestrians to pass safely.
These lights are controlled by a centralized traffic control system or are timed based on traffic demand. Sometimes, sensors embedded in the road detect vehicle presence or cameras monitor traffic flow, allowing for adaptive signal timing. Additionally, pedestrian crossing signals are often integrated into the traffic signal system, featuring illuminated symbols or text indicating when they should walk or wait.
Traffic signals serve a crucial role in effectively managing the flow of vehicular and pedestrian traffic, ensuring safety and minimizing congestion. Their presence helps regulate traffic movements, reducing the risk of collisions and ensuring a smooth and orderly transit experience for all road users.

Etymology of TRAFFIC SIGNALS
The word "signal" derives from the Latin word "signum", meaning "mark" or "indication". It entered the English language in the late 16th century. The word "traffic" originated from the Middle French word "trafique", meaning "trade" or "commerce", which was derived from the Italian word "traffico". Over time, "traffic" expanded its meaning to encompass the movement of vehicles and pedestrians. Therefore, "traffic signals" refer to the devices that provide indications or marks for the regulation of vehicular and pedestrian movements.
