Design and Implementation of an IoT-Based Smart Emergency Alert System

Abstract

Road accidents on highways often result in delayed emergency response due to the absence of immediate accident reporting mechanisms, particularly in remote areas with limited communication infrastructure. This delay can significantly affect the chances of timely medical assistance and rescue operations. To address this challenge, this paper proposes the Smart-Rescue System, an IoT-based emergency response solution designed to detect accidents automatically and transmit real-time alerts to emergency services. The system integrates an ESP32 microcontroller with motion sensors, GPS, and GSM communication modules to continuously monitor vehicle conditions and detect abnormal events such as sudden impacts or hazardous situations. When an emergency is identified, the system automatically sends an alert message containing the precise geographic location of the incident to nearby hospitals, rescue teams, and predefined contacts. Experimental evaluation of the prototype demonstrates that the system can rapidly identify accident conditions and significantly reduce emergency response delays. The proposed system can be integrated into intelligent transportation infrastructures and smart highway safety frameworks to enhance emergency management and improve overall road safety.
