Comparison Study On The Driver’s Eye Movement Characteristics Of Ordinary And Urban Road

With the rapid growth in the number of highway mileage and cars, China hasmade great strides in transport. Transport increases the development of China’seconomic, but it also brings many traffic accidents which have been recognized asthe world’s first victims. In the traffic system constituted of pedestrian, vehicle androad, the driver is the dominant factor who percept the information of vehicle androad environment, and driver factors is the most important factor causes a trafficaccident. Driver percepts traffic information through the visual in the process ofdriving mainly. So therefore the study on the driver visual characteristics has a veryimportant significance for improving the traffic safety.The statistics show that there are more accidents in urban roads and highway,this article select the city roads and highways as test environment. On the basis oftheoretical research on the driver’s visual characteristics were analyzedretrospectively, the paper analyzed the commonly used parameters in the driver’svisual characteristics, The distribution of the fixation point gaze duration, X(horizontal) and Y (vertical) direction perspective, the fixation point transitionprobability, the fixation point spacing, scanning the duration and panning speed areselected as the parameters to analyze and compare the driver’s visual characteristicsin ordinary roads and urban roads.The real vehicle experiments are carried in environment of highway and urbanroad, and the eye tracker records indicators of the diver’s visual characteristics. Thispaper analysis the variance and non-parametric significance of test data in two roadenvironment, contrast between the driver visual characteristics. The analysis resultsshow that there are significant differences in the visual characteristics of the driverin two road environment. In the ordinary road environment, the area of interest, the driver’s viewing angle distribution of the horizontal, vertical direction，fixationduration, and saccadic speed are different significantly from urban road. Howeverthe parameters are not very different, such as gaze point transition probability, thefixation point spacing and the duration of scanning.
