The Influence Of Landscape Factors On Driving Behavior Based On Driving Simulation Experiment

Highway as a major component of the road transport system, the landscape greening set standards on the traffic system has a more important impact. In this paper,the driving simulation experiment is combined with the driver's experience,and the driving simulation experiment is carried out in the relationship between the road landscape factor and the driving behavior in view of the current research method of road landscape greening design.Based on the previous literature, the mean value of the velocity, the lateral position offset and the standard deviation of the velocity and lateral position parameters are taken as the characterization of the driving behavior. The road environment and the roadside trees are constructed by road modeling software such as uc-win / road and the simulation of the different types of roadside trees were introduced from the road modeling software, and the subjects were invited to carry out simulation experiments and subjective evaluation, and then use the relevant software to the experimental data processing and classification, and finally the relevant data to conduct a comparative analysis to study the different settings of road landscape factors will have an impact on driving behavior. Through the change of velocity and lateral position offset, the driving behavior change of the driver under different landscape factors is compared with the magnitude of the curve change and the quantitative standard deviation. From the mathematical analysis of the driving behavior data, the different levels of the height, spacing, road margin and color matching factors of the roadside trees will affect the driver's feelings and driving behavior. Unreasonable road landscape factors make it easy for the driver to control the lateral position and speed, to stimulate the higher frequency of road landscape greening factors are easy to lead to increase the driver's psychological pressure and visual load, unreasonable landscape factor configuration will make driving The stability of the driving stability.According to the experimental data analysis, it is concluded that unreasonable landscape factor configuration will affect the driving behavior. The results show that in the scene of simulated simulator, the height is 3m, the distance is 10m, the roadside distance is 0.75m, the color is the appropriate matching landscape factor configuration is the better choice, and this kind of scene has little effect on human driving behavior.In the simulation system, the suggestions are given for the roadside landscape and the arrangement and selection of trees in the process of road greening design, which has certain reference value for the landscape factor configuration in the future road greening design process.
