Vehicle Accident Detection and Warning System for Sri Lanka Using GNSS Technology

As the usage of vehicles is increasing drastically in Sri Lanka, the rate of road accidents is also increased today, especially two-wheelers. Low and middle-income countries like Sri Lanka are the most affected because road traffic crashes and injuries are linked not only to the number of vehicles, road conditions, and drivers' behavior but also to the country's level of economic and social development. The main causes for these mishaps are due to the fault of driver/rider like, high-speed, drunk and drive, diversion of minds by stress or electronic gadgets as well as faults of authorities such as poor road infrastructure, inappropriate mixing of vehicle types, inadequate traffic law enforcement and delayed implementation of road safety policies, etc. Even some mild injuries may cause severe problems to a victim without prompt medical health. The physical condition of the victim who met with an accident is not always going to be good enough to seek medical help. Sometimes the victim may be in an unconscious stage or maybe fainted away. This paper deals with automatic accident detection and also introduces automated accidents alerting when the accident occurs to the vehicle. Once the accident occurs to a certain vehicle, the proposed system will detect it and send an alert containing the required information to a certain registered number instantly.
