IoT-Based Ambulance Traffic Signal Priority and Emergency Route Management System

This paper presented a Smart Ambulance Priority System Using IoT for improving ambulance movement through traffic intersections. The proposed system integrates RFID-based ambulance authentication, GPS-based location tracking, ESP32-based IoT communication, Firebase cloud storage, traffic-signal priority, and web-based monitoring. The system provides an integrated mechanism for identifying an authorized ambulance, transmitting its emergency information, providing traffic-signal priority, and monitoring ambulance information through a centralized dashboard. After the ambulance passes the intersection, the traffic signal can return to its normal operation. The physical prototype demonstrates the feasibility of integrating low-cost IoT hardware and cloud technologies for emergency traffic management. Future development can extend the system through V2X communication, smart lane reservation, multiple connected intersections, cellular communication, and real-world traffic-management infrastructure.
