Setting Of Mountain City Road Intersection Traffic Signs

Urban road intersection is the important component of urban road network. which one is the Turning vehicles and pedestrians concentration and evacuation. The condition of intersection traffic has a serious impact on the entire road network traffic. Under the influence of topography, Mostly mountainous city road intersection in the form of deformity intersection,the small angle and the road longitudinal slope is too large, Around the intersection and there may be a slope, The above situation will affect the vision of drivers at the intersection.It mast Lead to bad drivers’ visual and the intersection observation is not enough. Traffic signs, as a kind of traffic tools of presentation, Through a certain pattern of Chinese and characters to give the information about the road ahead to the driver. But due to the mountainous city road and city road on the terrain distinguishing ordinary plain, If in accordance with the principle of ordinary plain city intersection traffic signs Settings to set up the mountain city road intersection traffic signs, This will cause the driver to the traffic signs reading incomplete or driver observation of the intersection time less than wait for a phenomenon.First of all, Through the analysis of the characteristics of mountainous city road intersection to study the difference of mountainous city road intersection traffic signs settings and ordinary urban road intersection traffic signs. Conclusion the faults of the signs,which one was seted in the mountainous city road intersection.Through the analysis of the visual characteristics of the pilot before entering the intersection and driving characteristics, building up the driver’s visual model and driver model. Through mathematical transformation of the model more intuitive response traffic sign set up front distance, high marks layout design, Chinese character word the three elements required. Secondly discuss the driver’s visual characteristics, Mainly embarks from the driver’s dynamic visual features, Divides into the driver’s dynamic visual patterns look, scanning and blink, Analyzed the relationship between the three kinds of eye movement form. And then to rem three basic mode to star, Analyzed the driver in the visual search pattern in the process of driving, Finally determine the driver’s visual behavior characterization parameters, Theoretical basis for the back of the test. Then through the theoretical basis for design of mountainous city road intersection in front of the driver’s eye movement experiment, selection of test section. use the eye movement instrument record the driver’s visual parameters, analysis of mountainous city road intersection Angle on the driver’s eye movement parameters and find out the influence of driver’s eye movement parameters change rule.According to the laws of the eye movement parameters of drivers of traffic signs drivers of traffic signs reading model is established and the driver driving model of the intersection, two models of mathematical reasoning, draw a mountain city road intersection traffic sign set three parameters(a prerequisite for the set distance, high words of Chinese characters and the layout of traffic signs)...
