Traffic Light Control System

The scope of this project is to suggest a proposal in the implementation of traffic light control system based on Programmable Logic Controller (PLC) at a two-way intersection for minimizing the effect of traffic jam such as long waiting time, congestion etc. In this program sensors are used to detect the presence of vehicle at every route, if the presence of vehicle is not detected then the route is omitted form the operation of that cycle. The program also guides a safe context for the pedestrian crossing. The cycle of operation can only be stopped if there is no presence of vehicles at every route or if any two of the four "pedestrian crossing request switch" which are present at every origin of crosswalk is pressed, this permits the pedestrians to cross safely.
