Project Idea
Build an intelligent traffic light system that adjusts signal timing based on real-time traffic conditions. Using sensors to detect vehicle density on roads, this system optimizes signal changes to reduce congestion and waiting times. Ideal for urban traffic management, this project introduces students and enthusiasts to automation, sensor interfacing, and smart city concepts.
Project Description
This project implements a Smart Traffic Light system using Arduino and IR sensors to monitor the traffic on each road lane. Based on the number of vehicles detected, the system dynamically allocates green light duration to minimize traffic congestion. An Arduino Uno serves as the main controller, taking input from the sensors and operating the traffic lights (LEDs) accordingly. The system can be expanded using cameras, IoT modules (like NodeMCU), It is powered by a battery system and is suitable for scale models.
