Trainer of Traffic Light System Based on PLC

Abstract

Currently traffic congestion becomes one of the problems especially in big cities. Therefore, the traffic system needs to be applied in order to avoid severe traffic jams and traffic accidents. This research discusses about traffic system at an intersection that is simulated on the trainer that made in such a way that resembles the street intersection of five in general with based PLC Omron CQM1H-CPU51 series. This traffic system simulation works using a timer that has been set in such a way. On the trainer, there are five paths in which each path is installed green, yellow and red lights and 2 buttons to start and end the program. The green light is on for 25 seconds and the yellow light is on for 5 seconds while the red light keeps on when the green light at another intersection lights up.
