| The virtual reality is applied to the study of drivers’ visibility in traffic scene, whichhelps to study design specifications effected by the virtual visual, to provide basis fordecision making to improve the fidelity of virtual scene.Various objective and subjective factors are analyzed which affect driver’s visibilityduring their driving, the visibility evaluation system is built which impacts the virtualtraffic legibility, a virtual traffic scene is built with the use of software3ds Max. Thedrivers are invited to do some driving simulation experiments, fill out questionnaires, andthen with the help of spss16.0software for the experimental data analysis, and do somevisual changes based on the results of the questionnaire related. The experiment is repeatedtwice to get the best visual scene; and finally an legibility evaluation model is establishedbased on the improved integrated transport scene, Some comprehensive evaluations aremade about three sets of virtual traffic visibility scene; which provides a reference basis forthe future establishment of a virtual traffic scene.According to the validation on the experimental data of questionnaire and model,theanalysis on influencing factors about the virtual traffic scene legibility is resulted: roadsand marking, signage, landscaping, pedestrian and bicycle,maps and textures, scale, age,etc. set a greater impact on legibility; the modified on perspective, textures and textures,lighting and shading effects, as well as related models’ color, the legibility is improvedsignificantly, but the effect of the interaction between the various factors can not beignored; the secondary questionnaire compared to the original value, the result is moresatisfactory. Establishment and optimization of the virtual scene have a very importantreference to the visual design of virtual traffic and road transport facilities. |
