RFID-Assisted Priority Traffic Management System with Real-Time Vehicle Density Sensing

In this work, we present a smart traffic control system based on RFID technology for emergency vehicle prioritization and real-time sensing of vehicle density for traffic light control optimization. Emergency vehicles are fitted with RFID tags, and these are picked up by RFID readers installed at intersections so that the system can dynamically override default signal patterns to generate a green route. Concurrently, sensors like ultrasonic or IR modules track vehicle counts at different lanes to make adaptive signal timing possible in accordance with current traffic conditions. The decision-making is coordinated by a control unit that is microcontroller-based. This system enhances emergency response time and minimizes traffic jams and offers a scalable solution for today's smart city scenarios.
