A Study on Driver's Dynamic Visual Characteristics

The driver's visual characteristics and road safety are closely related. Previous studies show that 80% of the divers' information of the road is obtained by their eyes. Therefore, the visual characteristics are closely related to driving operations. In this paper, on the basis of the theoretical analysis at home and abroad before, dynamic visual characteristics research about two different categories of drivers (professional and non-professional drivers) in real-world road environment have been explored. In the research, eye tracking system was used to study regularity of fixation duration and the perspective distribution. Two kinds of drivers were compared and conclusion of distribution visual feature had been made. It was found from this study that the driving experience had an obvious effect on the drivers' eye movement characteristics. It was concluded from the study of perspective distribution that the drivers' concern on the vicinity was more than the objects in a distance. The findings from this study will assist the design of roadway, satisfy drivers' driving request, and make the roadways safer.
