PLC Control Traffic Light System

Abstract: A Programmable Logic Controller (PLC)-based Traffic Light System offers an efficient and automated solution for managing traffic at intersections.Traditional traffic light systems operate on fixed timers.Which often struggle to adapt to changing traffic conditions, resulting in congestion and delays. Implementing PLC technology enhances the reliability, flexibility, and responsiveness of traffic control systems. This system utilizes sensors, timers, and PLC programming to control traffic signals dynamically. The use of a PLC ensures high-speed processing, real-time control, and easy modification of traffic rules without requiring major hardware changes. Additionally, emergency vehicle prioritization and pedestrian-friendly crossing mechanisms can be integrated to improve safety and efficiency.
