The main intention of the project is to find the accident spot at any place and intimating it to ambulance through GPS and GSM networks. The GPS based vehicle identification module contains vibrating sensor GSM module and a GPS modem connected to the microcontroller. The receiver section consists of a GSM receiver and a GPS receiver. The transmitter sectionconsists of a micro-controller, GPS module, GSM transmitter, Infrared Sensor, vibration sensor, and ultrasonic sensor.An automatic alarm device for road traffic accidents is introduced in this paper. It can automatically find a road traffic accident, search for the spot and then send the basic information to first aid center within small time seconds covering geographical coordinates, the time and circumstances in which a traffic accident takes place. GPS software is fitted in the vehicle will now start communicate with the satellite and get the latitude and longitude values and send the information to the centralized server. Then the server will search the nearest hospital and send the accident information to the hospital. The hospital will then be sending the ambulance to the accident zone.
