This study discusses the implementation of a smart traffic light system based on a Programmable Logic Controller (PLC) and sensors to improve traffic flow efficiency and reduce congestion at intersections. This system is designed to detect the presence of vehicles using infrared sensors integrated with a PLC, which functions to dynamically adjust the duration of green, yellow, and red lights based on traffic volume. By using an algorithm that calculates the time required for the green light to turn on based on the number of detected vehicles, this system is able to optimize vehicle waiting time. The test results show that the implementation of this system can reduce the average waiting time by up to 20% and improve safety at intersections. This study also identifies potential for further development, such as the use of cameras for vehicle detection and increasing the number of sensors for wider coverage. Thus, this smart traffic light system is expected to provide an effective solution to the problem of congestion in urban areas.
