Abstract: Traffic congestion in urban areas often delays ambulances during medical emergencies, which can lead to serious consequences for patients. To overcome this problem, an intelligent traffic control system is required to provide priority to emergency vehicles. This paper proposes an RFID-based ambulance monitoring and traffic control system that helps ambulances pass through traffic signals without delay. In this system, ambulances are equipped with RFID tags, and RFID readers are installed at traffic intersections. When an ambulance approaches the signal, the RFID reader detects the tag and sends the information to the Arduino microcontroller, which automatically changes the signal to green for that route. This allows the ambulance to move quickly through the intersection. The system also includes patient health monitoring using pulse and temperature sensors inside the ambulance. These health parameters are transmitted wirelessly to the hospital using Zigbee communication, enabling doctors to prepare for treatment before the ambulance arrives. This system helps reduce ambulance delay, improve emergency response time, and enhance patient care through smart traffic management.
