How does a traffic light work?

Traffic lights work on a timer, but if you look closely on the road when your stopped at the traffic lights, you should see a rectangle like shape under the car it is called a sensor And when you drive on it, a signal is sent, so the timer knows a car is waiting, if no other cars are going the other way, the timer will change and the light will go green so you can go. I hope this answer helps.


What is inside of the traffic light?

Inside a traffic light are control circuits, LED or incandescent lights, and a timer mechanism. The control circuits manage the sequencing of the lights, while the lights themselves are responsible for displaying red, yellow, and green signals. The timer mechanism ensures that the lights change at appropriate intervals.


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.
