Traffic lights are primarily used to control the flow of vehicle and pedestrian traffic at intersections, ensuring safety and reducing the likelihood of accidents. They regulate the timing of vehicle movements, allowing for orderly transitions between red, yellow, and green signals. Additionally, traffic lights can help manage congestion and improve traffic efficiency by coordinating the movement of vehicles and pedestrians. In some cases, they also provide specific signals for cyclists and public transport vehicles.

What is the energy transformation of a traffic light?

Its most customary meaning is 'signal light' or 'traffic light' such as those typically found at the corner of busy intersections in cities. However, it can also mean a flashing light communications system, or a communications system that uses flags.
How do traffic light sensors work?
Traffic light sensors work by using various detection technologies such as inductive loops, video cameras, or radar sensors to monitor traffic flow at an intersection. These sensors can detect the presence of vehicles waiting at the intersection and communicate this information to the traffic signal controller. The controller then uses this data to optimize the timing of the traffic lights and improve traffic flow.
What is the opposite of heavy traffic?

What happnes if the traffic light system brakes down?
If a traffic light breaks most cities will assign a traffic cop to regulate traffic until the light can be fixed.
