S-CarCrash: Real-time crash detection analysis and emergency alert using smartphone

Abstract

Vehicular accidents are one of the leading causes of fatalities across the world. Survival rate depends largely on the time between the accident and when emergency responders arrive or are dispatched to the scene. One way to reduce the delay between accident and emergency response is to use in-vehicle automatic accident detection and notification systems. These in-vehicle accident detection systems are typically available in luxury/expensive vehicles. In several low-end cars especially in developing countries such accident detection systems are not installed by OEMs. In this paper, we attempt to address this problem by proposing an automatic accident detection system based on smartphone. Our algorithm reliably infers an accident based on the data collected through various smartphone sensors in spite of their sensitivity and range limitations. Such a system can prove to be a cheaper alternative to the costly accident detection systems installed in luxury vehicles.
