Abstract : Road accidents and personal emergencies claim thousands of lives annually, largely due to delayed response and the inability to relay location-specific distress information. Existing automated accident detection systems, while technically sophisticated, are prone to false positives under normal vehicular conditions, undermining their real-world reliability. This paper presents Project SAVE (Smart Accident and Vehicular Emergency), a manual-trigger-based emergency alert system built on an Arduino Uno microcontroller, a SIM900A GSM module, and a NEO-6M GPS module. Upon deliberate activation via a push button, the system acquires real-time GPS coordinates and transmits an SMS containing a Google Maps hyperlink to predefined emergency contacts. This design prioritizes user agency, cost-effectiveness, and network independence over full automation. The system was evaluated for GPS fix acquisition time, SMS delivery reliability, and component cost, demonstrating consistent performance under open-sky conditions at a total hardware cost below ₹2,500. A comparative analysis against sensor-based and smartphone application-based systems is presented, along with the system architecture, component specifications, methodology, limitations, and future scope.
