Mountain Highway Drivers Visual Information Cognition Research

In the face of the increasing traffic demand, the construction of highway in our country to flourish, but due to the complex mountainous terrain conditions, traffic infrastructure construction is not perfect, there are many bad line and space mountain area highway, the driver driving in such conditions when the driving load increases, in person, vehicle, road and environment under the action of single factor or multiple factors can lead to traffic accidents. To prevent the occurrence of traffic accidents, must be made up of people, vehicles, road and environment factors for effective control of the traffic system, in this system, one is the dominant factor, road and environment will be guiding effect on the person’s psychology. So this article research goal is on the basis of experimental study on the combination of psychology, analyze the driver in the mountainous area highway environment the visual characteristics of the expressway in mountainous area of linear, traffic signs, and provides the basis for landscape design, make it conform to the principle of people-oriented design, improve the level of road safety and reduce the incidence of traffic accidents.Based on UC- win/Road software simulation of the real environment in the mountainous area highway, combined with the eye movement instrument and simulated driving device, simulated test drive, the participants were for young students, 16 copies of valid samples were generated. Based on the experimental data obtained, using the K value clustering algorithm will pilot fixation point coordinates, clustering analysis, will be the driver’s vision plan is divided into five regions. Drivers look at characteristics of the five areas and the goal of information analysis, found that low in a mountainous area highway driving experience drivers more when they are in front of the road area within the scope of the information, and the driver information focuses on target for road alignment information, followed by the traffic information, on the premise of guarantee the driving safety, the driver also will focus on some target has nothing to do with the traffic information.Using market theory, and then got the driver five area divided by the view point of probability transfer matrix and carries on the differences in test, through the analysis found that low driving experience driver put great attention in the process of driving on the road ahead, little concern for the change of the road on both sides of the information, when access to information, a large part of information, to drivers need to be repeated many times to repeat at the area of to complete. In driving experience for 1 year industry could be divided into two groups, the driver found the most significant difference between the two groups of drivers is the attention on the road in front of the area and on the left side of the area, driving experience more than a year of drivers on the road in front of thinned, to increased focus on the left of the road. Gazes at the steady state distribution was carried out on the driver’s view point, think after watching behavior stable low driving experience driver will more area of the distribution of attention to the road ahead, in comparison, 1 years driving experience with driver will be less concerned about the road ahead, to strengthen the awareness of the road on the left side of the area.Based on dynamic visual look at behavior characteristics, calculation and get the distribution of the highway the driver fixation point trajectory, the long straight sections and bend sections of the driver visual characteristics are analyzed. Based on spatial interface is surrounded degree, divided into the mountainous area highway three visual spaces, open space, half closed space, closed space. On the driver’s visual features in the three space is analyzed, the driver in the three kinds of space travel, the most high-profile area is depending on the road in front of the area, and the driver’s viewpoint in open space distribution is relatively uniform, while half closed space and closed space appeared different degree of dispersion; Drivers on the road visual space of open when the driving load is small, have the joyful psychological experience, and in the closed space travel has a big ups and downs of psychological fluctuations; Pilot run on the three kinds of visual space, the degree of psychological experience pleasure while driving: open space > > half closed space closed space.Finally, depending on the analysis results of highway environment landscape construction are proposed.
