An efficient mobilization of people & transportation of goods material is very important for overall development of any country .It is achieved through airways, waterways & roadways. Traffic controlling signals are very important part of the transportation system.
Traffic signals are of two types-
1. pre timed signal system
2. Actuated signal system
In pre timed signaling controls the controller sets the timing based on predetermined rates.
In case of actuated signaling system the signal timing is adjusted depending on the actuation of vehicles that is if the number of vehicles are more than the controller adjust such that the green time is more.
