VEHICLE CRASH LOCATION DETECTION AND ALERTING SYSTEM USING ANDROID SMART PHONE AND GPS TECHNOLOGIES

VEHICLE CRASH LOCATION DETECTION AND ALERTING SYSTEM USING ANDROID SMART PHONE AND GPS TECHNOLOGIES

ABSTRACT

Nowadays varying degrees of road crashes have been recorded from both developed and developing nations of the world. Crashes especially those that involve loss of lives around the world and in particular in developing countries is alarming. The existing solution is in-vehicle accident detection system, which is expensive. In this research work, a less expensive and system that can be widely used to reduce the time to report and respond to vehicle crash was developed. The system consists of two mobile-phone-based applications, the User or victim’s App and the agency App. The victim App uses the in-phone accelerometer and General Packet Service (GPS) to detect a crash and its location coordinates respectively, and then a notification is sent to a concerned agency. A maximum of three concerned agencies location coordinates with their respective phone numbers were stored on a firebase (cloud database) account for mapping to the closest crash site and then send an SMS with the location coordinates and the Google map image of the crash site in real-time . The agency App is used to register an agency on the firebase. To be able to view the Google map images, each of the concerned agencies had a smart phone. The two Apps were developed and implemented using Android Studio Integrated Development Environment (IDE), with Java programming language for the events and Extended Mark-Up Language (XML) for the interface design. The implementation was strictly on Android smart phones with minimum Application Programming Interface (API) level 16. The system validation proves high sensitivity of 93%, accuracy of 91%, precision of 92% and specificity of 87% which shows that the system is efficient and effective.
