Relay based traffic contol system using infrared pair detectors

A relay is an electromechanical device that is actuated by an electrical current. The small current flowing in relay circuit causes the opening or closing of high power requiring circuit. The proposed traffic control system in this project will be a simple relay based controller system which can adapt according to the amount of traffic in one direction. The relay will require only small amount of current for its operation but will be used to operate high power requiring traffic lights. Also relay switching will be used to operate more number of components with the same port. The system will require relay board, microcontroller and IR sensor for its implementation. In every direction the road will consist of an IR transmitterreceiver pair at a certain distance from traffic lights. When the traffic will become heavy in one particular direction during emergency situations it will increase the time duration for that particular road thus will help in getting rid off from the heavy traffic congestion which would not have been possible if the timing sequence of the system has been kept fixed
