The IoT-Based Smart Traffic Management System is an advanced intelligent transportation solution developed to reduce traffic congestion, improve road safety, and optimize vehicle movement using Internet of Things (IoT), Artificial Intelligence (AI), and Deep Learning technologies. The system integrates IoT hardware components such as IR sensors, ultrasonic sensors, RFID modules, NodeMCU/ESP8266 microcontrollers, cameras, and wireless communication modules to collect real-time traffic data from road intersections and traffic signals. The captured data is transmitted to the central monitoring system through IoT communication protocols for real-time analysis and decision-making. The proposed system uses the YOLOv8 deep learning model for vehicle detection and counting from live camera feeds. Based on the detected traffic density, a Deep Q-Network (DQN) reinforcement learning algorithm dynamically adjusts traffic signal timings to reduce waiting time and improve traffic flow efficiency. The IoT sensors continuously monitor vehicle movement and congestion levels, while RFID technology can provide priority access for emergency vehicles such as ambulances and fire trucks. A professional dashboard developed using Python Tkinter and Matplotlib displays live traffic video, traffic density, congestion level, signal status, and graphical traffic trends in real time. The intelligent system automatically predicts congestion conditions and optimizes signal control without manual intervention. By combining IoT hardware, AI-based traffic analysis, and smart signal automation, the system helps reduce fuel consumption, travel delay, and air pollution while improving transportation efficiency and urban mobility. The proposed Smart Traffic Management System offers a scalable, cost-effective, and reliable solution for smart city infrastructure and future intelligent transportation systems...
