The evolution of urban infrastructure necessitates increasingly sophisticated control mechanisms to manage the dense flow of modern traffic. This project presents a high-level automated solution for a three-phase traffic light system using a robust PLC (Programmable Logic Controller) architecture. The study integrates the Rockwell Automation software suite specifically Studio 5000 Logix Designer and FactoryTalk View Studio to create a synchronized environment where control logic and user monitoring coexist. By leveraging Studio 5000 Logix Emulate, the system provides a risk-free testing ground that mirrors physical industrial hardware. This paper details the systematic approach to configuring the 50-second signal cycle, the mapping of I/O addresses, and the development of a SCADA interface that offers real-time visualization of the intersection’s status.
