In order to keep a highly safe and reliable system of car driving, it is important that the system would be considered as a man-machine system including not only the feature of vehicle movement but also human perception, cognition, and motion of a driver. In this paper, it is examined to clarify the relation between feature of eye movements and driving behavior in conventional and unconventional situation by the experiments using the driving simulator and the eye tracking system. The measurements of time histories of eye movements during the driving a road vehicle were performed in the situation of different traffic regulation by the simulator. The experimental system proposed in this paper is useful for analyzing human error induced from the different traffic regulation between Japan and USA scenarios. It is recognized in both turns that typical patterns of eye movements in horizontal axis appeared between start and end of the turns. It is also found that there were several times of a set of eye movements appeared in horizontal axis from the beginning to the end of turns. It is found from the time histories of eye movements by synchronizing vehicle data when the overshooting in the right turn and undershooting in the left turn that resulted in head-on crash, the time and number of eye fixation with overshooting or undershooting spent in cognition and motion stages in vehicle operation became larger than that without overshooting and undershooting.
