Automatic Vehicle Accident Detection and
Messaging System Using GSM and GPS
Modem

ABSTRACT: The Rapid growth of technology and infrastructure has made our lives easier. The advent of technology
has also increased the traffic hazards and the road accidents take place frequently which causes huge loss of life and
property because of the poor emergency facilities. Our project will provide an optimum solution to this draw back. An
accelerometer can be used in a car alarm application so that dangerous driving can be detected. It can be used as a crash
or rollover detector of the vehicle during and after a crash. With signals from an accelerometer, a severe accident can
be recognized. According to this project when a vehicle meets with an accident immediately Vibration sensor will
detect the signal or if a car rolls over, and Micro electro mechanical system (MEMS) sensor will detects the signal and
sends it to ARM controller. Microcontroller sends the alert message through the GSM MODEM including the location
to police control room or a rescue team. So the police can immediately trace the location through the GPS MODEM,
after receiving the information. Then after conforming the location necessary action will be taken. If the person meets
with a small accident or if there is no serious threat to anyone`s life, then the alert message can be terminated by the
driver by a switch provided in order to avoid wasting the valuable time of the medical rescue team. This paper is useful
in detecting the accident precisely by means of both vibration sensor and Micro electro Mechanical system (MEMS) or
accelerometer. As there is a scope for improvement and as a future implementation we can add a wireless webcam for
capturing the images which will help in providing driver`s assistance.
KEYWORDS: GSM, GPS, Vibration Sensor, ARM Controller.
I.INTRODUCTION
The high demand of automobiles has also increased the traffic hazards and the road accidents. Life of the people is
under high risk. This is because of the lack of best emergency facilities available in our country. An automatic alarm
device for vehicle accidents is introduced in this paper. This design is a system which can detect accidents in
significantly less time and sends the basic information to first aid centre within a few seconds covering geographical
coordinates, the time and angle in which a vehicle accident had occurred. This alert message is sent to the rescue team
in a short time, which will help in saving the valuable lives. A Switch is also provided in order to terminate the sending
of a message in rare case where there is no casualty, this can save the precious time of the medical rescue team. When
the accident occurs the alert message is sent automatically to the rescue team and to the police station. The message is
sent through the GSM module and the location of the accident is detected with the help of the GPS module. The
accident can be detected precisely with the help of both Micro electro mechanical system (MEMS) sensor and vibration
sensor. The Angle of the rolls over of the car can also be known by the message through the MEMS sensor. This
application provides the optimum solution to poor emergency facilities provided to the roads accidents in the most
feasible way
