DEVELOPMENT OF A SMART ACCIDENT DETECTION AND ALERT SYSTEM USING SENSOR DATA AND GPS-GSM COMMUNICATION

Abstract

The intelligent accident detection system not only enhances safety but also reduces the time gap between an accident and medical assistance, which is often critical for saving lives. Unlike conventional vehicle safety mechanisms that are expensive and vehicle-specific, this solution is compact, cost-effective, and easily adaptable to helmets, making it highly practical for two-wheeler riders. The use of an accelerometer or vibration sensor ensures accurate crash detection, minimizing false alerts caused by minor shocks or bumps. Furthermore, the system can be extended to support cloud integration for centralized monitoring, IOT-based dashboards for live tracking, and voice call alerts in addition to SMS, making it more versatile. The rechargeable power supply with energy-efficient design allows long-term operation, while the architecture ensures easy upgrades with newer technologies like 4G/5G modules for faster communication. Its integration into daily commuting gear like helmets ensures that the safety mechanism is always with the rider, providing peace of mind for both the user and their families.
