This is the advanced accident detection system which is a help in case of the accident. In this system we use Arduino, GSM and GPS module. This system works when two cars hit each other. At that time the vibration of the car is used in the signal from and this signal is used and sent to the nearest hospital (ambulance) in the form of the SMS. This SMS is attached with the Google map link. When this SMS is open then the accurate location of the person is shown there in the time of 10 seconds. This system really works and it has a lot of advantages. Due to this system we can save a lot of people's lives.
