Real time wireless accident tracker using mobile phone

Abstract

Vehicle accidents are one of the most leading causes of fatality. The time between an accident occurrence and the emergency medical personnel are dispatched to the location of accident is the critical factor in the survival rate after an accident. By minimizing the gap time, mortality rate can be reduced. One approach to reduce the delay time is to use the Real Time Wireless Accident Tracker Using Mobile Phone, a system which automatically senses the occurrence of an accident of a vehicle and immediately notify central emergency dispatch server of the location of accident using Global Positioning System (GPS). The main purpose of this research is as an early accident detection. This system uses PIC 16F microcontroller, piezoelectric sensors, GPS and Global System for Mobile (GSM) modules to detect traffic accidents. When an accident occurs, the piezoelectric sensor detects and measures the severity of the force impacted on the vehicle and sends out a help message to central emergency server. Upon acknowledgement from the server, the system sends out another message containing GPS coordinate of the location.
