A Unique System to Prevent Rash Driving using Sensors of Smart Phones

According to the statistics from World Health Organization (WHO), traffic accidents have become one of the top 10leading causes of death in the world[1]. Specifically, traffic accidents claimed nearly 3500 lives each day in 2014.Studies show that most traffic accidents are caused by human factors, e.g. drivers' abnormal driving behaviors [2]. Therefore, it is necessary to detect drivers' abnormal driving behaviors to alert the drivers or report Transportation Bureau to record them. Although there has been works[3][4][5] on abnormal driving behaviors detection, the focus is on detecting driver's status based on pre-deployed infrastructure, such as alcohol sensor, infrared sensor and cameras, which incur high installation cost. Since smart phones have received increasing popularities over the recent years and blended into our daily lives, more and more smartphone-based vehicular applications [6][7][8][21] are developed in Intelligent Transportation System.
