The main purpose of this work is to identify automatically the position of the vehicles which met with accidents. The vehicle’s position and status are transmitted as latitude and longitude values through GSM and GPS with the mobile authorization two parameters i.e., latitude and longitude will describe the location anywhere on the Earth. The co-ordinates data will be acquired by the GPS receiver which will be fed to the microcontroller to display in the LCD. Whenever the vehicle is collided, location of the vehicle information will be transmitted to the concerned mobile automatically. Bumping sensor is used in collision sensing. Based on those signals, the controller collects the longitude & latitude data from GPS receiver and transmits to the concern mobile through GSM module. The experimental setup was installed in the ambulance which would control the traffic at signals until the vehicle crosses the crowdedareas. As often the ambulance has to wait until the normal traffic is cleared, and causes inconvenience to the patient life and who needs immediate treatment, to overcome this issue we designed a system which would be very helpful while the vehicle crosses junction or cross-roads. Therefore the proposed system could by-pass the existing signaling system for some-time.
