Intelligent Road Accident Detection and Emergency Response System Using IoT

This paper presented an IoT-based road accident detection and emergency alert prototype using an Arduino Uno, motion and vibration sensors, GPS, and GSM. Its intended workflow monitors vehicle conditions, detects abnormal sensor readings, obtains location coordinates, and sends an SMS to predefined contacts. The underlying thesis reports successful qualitative tests for simulated vibration, tilt, and impact events, with no alert reported during normal test conditions. The current evidence supports a preliminary functional demonstration, but not a quantified claim of high accuracy or reduced mortality. Future work should make the detection algorithm reproducible, implement complete GPS parsing and communication-failure handling, and evaluate the prototype using measured performance metrics and real-world trials. With these improvements, the design could contribute to a broader vehicle-safety and emergency-notification system.
