Application of industrial PLC for controlling intelligent traffic lights
Modern controlling flows today are unimaginable without the comprehensive use of computers. This paper describes the practical application of the PLC (Programmable Logic Controller) controller for controlling real-time intelligent traffic lights, and for the needs of the above, a traffic junction with a corresponding signaling was created, and an intelligent traffic light controlling system was implemented. For the realization of this work, the SIEMENS, SIMATIC S7-300 PLCs were used, which, with the help of sensors, monitors and manages the operation of the entire system. After the implementation of intelligent traffic control system, the results obtained by controlling traffic lights with and without the use of sensors are presented, and a comparative analysis is presented.
