RFID and GPS Based Emergency Vehicle Pre-Emption System

In urban areas, emergency vehicles such as ambulances and fire trucks often face significant delays at traffic intersections due to congestion. These delays can be life-threatening in critical situations. This project presents an RFID and GPS-based emergency vehicle pre-emption system designed to provide a seamless and automated way of granting priority to emergency vehicles at traffic signals. The system employs RFID tags on vehicles, RFID readers at intersections, GPS modules at signals to track locations, and GSM modules to notify control centers. When an emergency vehicle approaches, the system detects its RFID tag, overrides the traffic signal to green, and alerts nearby intersections, ensuring smooth passage. Integrating RFID, GPS, GSM, and microcontrollers makes the system cost-effective, scalable, and suitable for real-world deployment.
