The development of a transportation system has been the generative power for human beings to have the highest civilization above creatures in the earth. The automobile has a great importance in our daily life. We use it to go to our workplace, keep in touch with our friends and family, and deliver our goods. But it can also be a disaster to us and even can kill us through accidents. In 2015, TamilNadu registered a total of 69,059 accidents, nearly 14 percent of all road accidents in India. Speed is one of the most important and basic risk factors in driving.

It not only affects the severity of a crash but also increases the risk of being involved in a crash.So our proposed work can help such victims and reduce the fatality rate.We basically develop an android application in which the falling ratio is calculated. This can be done by using various sensors deployed in our smartphone such as triaxial accelerometer and also by using human fall detection technique. This triaxial accelerometer calculates the G-force value in X, Y & Z axis and if the G-force value greater than the threshold value then the emergency message will be sent to our emergency contacts.

The coordinates at that particular axis can be fetched using the tower signal from the base-stations.The GSM technology can be employed so that there is no need for any mobile connectivity.The already existing work related to this concept is to calculate the G-force value using the 3G/4G internet connections. And this model works only when connected to the internet and another related existing work is in which some wearable sensors which we found as robust as it is not comfortable to everyone to carry the sensors to each and every place and the cost of this method is also much higher due to the usage of many sensors.

Our Proposed work has two phases the detection and notification phase the detection phase used to detect the abnormal threshold value and capture the place Co-ordinates ‘ie’ Longitude and latitude points and the notification system use the service providers cellular network signal and sends the GSM precisely it will send SMS to our emergency contacts without the use of any GPRS,3G etc. In our proposed work we have an idea to develop an android application in which we develop a sign up activity and login activity and we create a local database and link the login contacts to the database and if the application is started after the login activity the G-force value is calculated and if any abnormal ratios are identified greater than the fixed threshold value then the message and the coordinates will be sent through SMS.
