FEASIBILITY STUDY OF REAL-TIME IOT BASED EMERGENCY VEHICLE ALERT SYSTEM FOR ROAD SAFETY

Abstract

Emergency vehicles such as police cars, fire trucks, and ambulances must reach their destinations quickly and safely. Sirens and warning lights are traditionally used to facilitate movement through traffic. However, some drivers unaware of their presence which leads to delays and hindering response times. To address this challenge, this study investigates the feasibility of an IoT-based emergency vehicle alert system that enhances driver awareness through real-time notifications and location information. The proposed system integrates a NodeMCU microcontroller, GPS module, and Firebase Realtime Database to transmit and store the emergency vehicle’s coordinates. MIT App Inventor is utilized to develop a smartphone application to display the real-time location of the emergency vehicle on a map and provides notifications to drivers within a 3.0 km radius. Feasibility testing was conducted to evaluate the system’s performance in terms of GPS data transmission, notification delivery, and location accuracy. The results show consistent data synchronization with Firebase, reliable notifications across the defined radius, and accurate representation of vehicle positions on the application interface. These findings confirm the practicality of the proposed approach in improving driver responsiveness and minimizing delays in emergency response.
