EMERGENCY VEHICLE DETECTION AND ALERTING SYSTEM USING RF MODULE

As a prototype, this paper proposes an intelligent lane clearance and collision avoidance system, which would avoid delays of emergency response vehicles. It is basically a smart RF-based emergency vehicle detection system by fixing an exclusive RF module and Wi-Fi enabled Arduino microcontroller to the emergency vehicle and a signal reader or sensor to each vehicle on the road. If the vehicle gets closer to an emergency vehicle, the micro controller sends data to the nearby vehicle through radio frequency (RF), and the nearby vehicle displays some text regarding the presence of the emergency vehicle. The Global Positioning System (GPS) feature will assist in sending alerts from emergency vehicles to normal vehicles only on the way to the emergency vehicles’ destination by fixing the source and destination for both emergency response vehicles and normal vehicles. Emergency vehicles can trigger the traffic light signal to change from red to green in order to make clearance for their path automatically. When the emergency vehicle has completed crossing the road, the traffic light operations will return to normal using radio frequency. The Arduino microcontroller can delay the traffic signal to some extent according to the crossing time of an emergency response vehicle.
