A smart vehicle accident identification and messaging system using GSM and GPS module

Abstract

In most cases, it is not possible to find the accident location very quickly result in delaying the assistance reached to the individual. The objective of this work is to locate a traffic accident by transmitting a message through a device installed inside the vehicle. An ultrasonic sensor is used in this work in a car alarm application to identify vehicles in unsafe areas. Additionally, an accelerometer and vibration sensors are used to accurately track the accident due to the vehicle's rapid acceleration and vibration. A serious accident can be detected using signals from an accelerometer and vibration sensors. When a vehicle is involved in an accident, the vibration sensor detects the signal instantly, and if the car flips over, the accelerometer sensor identifies the indication and directs it to the microcontroller. Consequently, the microcontroller warns the nearby police station or rescue team to send an alert message through the GSM module, together with the specific location. If the accident is minor or the risk is not imminent to anyone's safety, the communication can be switched off by the car user using a switch, saving the emergency rescue team precious time.
