Vehicle Accident Detector and Notifier

Abstract

This paper presents a system to detect traffic accidents, notify emergency responders and store pictorial data for postaccident analysis. The proposed system is basically divided into three phases; the accident detection phase, the notification phase and the storage phase. The accident detection phase has core components as MEMS and vibration sensor. The unusual vibrations sensed and the tiltation or toppling of the vehicle are understood by vibration sensor and MEMS respectively as an occurrence of accident. The main components of the accident notification phase are GSM and GPS whereby the GPS tracks the coordinates (latitude and longitude) at which the vehicular accident has happened and the time during which the accident occurred. The GSM sends these information to emergency responders and concerned authorities through SMS. The storage phase consists of OV7670 camera and SD card where the camera captures the pictures during the accident and save the image data in SD card. Through interfacing of these various sensors with Arduino programming, the prototype was able to detect an impact and send coordinates through GSM using SMS. Similarly, the image data captured during the impact was also able to store in the SD card. The proposed system has an advantage of getting people’s lives saved and reduce statistics of death rate due to vehicle accident by providing faster response to the vehicle accidents.
