An analysis of the impact of driving time on the driver's behavior using probe car data

Abstract

Abstract: Driver's fatigue is an important factor of traffic accidents. Therefore, a fatigue detection system which achieves a small burden on a driver is expected to be developed, which stimulates drivers after long hour driving to take a rest at an appropriate timing when the driver's fatigue is detected. In order to give warning at an appropriate timing, knowledge about the impact of continuous driving hours on driver's behavior should be obtained. Recently, a rapid spread of ITS technologies enables us to analyze driving behavior in detail by using a large quantity of probe car data. This study analyses the impact of continuous driving hours on driving behavior when a vehicle is traveling on an expressway based on the probe car data. It is shown that the continuous driving hour affects driving behavior significantly. From the results, it can be concluded that driver had better take a rest every 5,000 [s]approximately.
