The normal function of traffic lights requires sophisticated contraband coordination to ensure that traffic moves as smoothly and safely as possible and that pedestrians are protected when they cross the roads.
A variety of different control systems are used to accomplish this, ranging from simple clockwork mechanisms to sophisticated computerized control and coordination systems that self-adjust to minimize delay to people using the road.
Traffic congestion has become problem not only in town but also in housing area and sub urban. This problem is due to rapid increase in number of vehicles.
The objective of this project is to develop a traffic light system based on a real traffic light. This system is designed to control or make sure the smoothness of traffic during the peak hours
Traffic light controller
This model using plc as a controller.
The dc power supply is responsible to give input signal to plc.
The presence of vehicle during traffic jam will be sense by switch.
How it operates ?
Every lane and traffic light signals have been labeled with A,B,C and D to separate each lane and traffic light.
Each traffic light lane has their set of traffic signals red, green and yellow.
It changes from red to green
And then yellow after that back to red signal.
