Detecting Aggressive Driving Behavior using Mobile Smartphone

Abstract

In the course of most recent couple of years, there has been an increasing interest to monitor driver’s behavior, road and traffic conditions in order to prevent accidents and save lives of the commuter. Different methods are available in the literature like special mounted vehicle cameras, sensors, Advanced Driver Assistance Systems (ADAS) etc. to monitor road, traffic conditions, and driver’s behavior. The use of mobile smartphone inbuilt sensors to monitor driving behavior has been one of the most cost-effective methods in developing countries like India. Earlier work in this paradigm mainly focuses on the use of mobile smartphone’s inbuilt accelerometer as a monitoring device for various driving maneuvers like sudden acceleration, sudden braking, and sharp turns. In this paper, we design and implement a system which uses an inbuilt accelerometer to detect sudden changes in acceleration; however, the system detects unsafe/sharp turns using inbuilt gyroscope in an efficient manner. The system further categorizes the driver as an aggressive or nonaggressive driver based on the observed driving pattern.
