Four-Lane Traffic Light Control System Using Microcontroller | radiomarket.in
Pickup currently not available
The Four-Lane Traffic Light Control System is an intelligent traffic management project designed to control traffic signals at a four-road intersection automatically. This system demonstrates traffic signal timing, automation logic, and smart city infrastructure concepts.
The project uses a microcontroller (Arduino/NodeMCU), LED traffic signal modules (Red, Yellow, Green), and timer-based or sensor-based control logic. Each lane is controlled in a predefined sequence to ensure smooth vehicle flow and reduced congestion. Optional sensors such as IR or ultrasonic sensors can be integrated to detect traffic density and adjust signal timing dynamically.
This project helps students understand traffic control algorithms, embedded systems, automation, and urban traffic management. It is ideal for engineering mini projects, diploma electronics projects, school science exhibitions, and smart city demonstrations.
Four-lane traffic control systems are widely used in urban intersections, highways, smart city projects, and intelligent transportation systems (ITS). The model can be enhanced with IoT-based monitoring, ambulance priority control, countdown timers, pedestrian crossing signals, and GSM alerts.
Available at radiomarket.in, providing reliable traffic signal kits, microcontrollers, sensors, and automation components.
