Abstract - Controlling and monitoring of traffic light control using schneider PLC is a modern and effective way to control traffic and prevent congestion and accidents. In this system the PLC is operated through a start and off switch and the traffic lights are given different priorities with the help of timers. The system controls a two-way traffic signal which controls the congestion according to their timings. The lights [red, yellow, green] execute according to the logic diagram. In the work that has been implemented a master circuit using the start and the stop pb with memory latching has been used. That memory latch has been used as the input along with timers to create the different light signals at the required interval of time. In general, the traffic light system is being controlled for each light based on traffic flow using proximity sensors that detect the presence of vehicles that are in the intersection of the roads. In the project the first red light keeps on for three time periods and the second lights keeps on blinking at the required time interval. The output is taken from common branches and implemented in the end. In real life the ladder logic diagram implemented is precise and easy to understand and use. It will help in preventing congestion and minimize accidents on roads.
