Vehicle Tracking and Accident Alert System Using GPS and GSM Modules

Abstract

Vehicle tracking systems are popular among people as a retrieval device and theft prevention. In this work, Global Positioning System (GPS) and Global System for Mobile (GSM) technologies have been used to design and construct a vehicle tracking and accident alert system (VTAA). The work integrates GPS receiver, microcontroller GSM module and push button for accident alert activation. The GPS module receives the coordinate of the point at which the system is located. The GSM module acts as a transmitter and receiver of data which is controlled by the user using command interface. The hardware component comprises of the push button, the microcontroller, SIM900, GPS receiver (sensor) and its integration with GSM module. The software component entails programming the microcontroller (ATMEGA328) with the source code, the Google map Application Programming Interfaces (APIs), the GSM message command, and integration with the GSM module. The system is controlled using a centralized interface. Whenever there is an accident, an alert message is sent automatically to the central dispatch server using the automatic alert system. The message is sent through the GSM module and the location of the accident is detected with the help of the GPS module. The result of the work which is user-friendly and reliable shows high sensitivity and accuracy.
