摘　　要：针对公路线形、交通环境与驾驶员的协调性实时检测的定量化评价方法问题,围绕虚拟现实技术和驾驶员道路安全感认知评价,在对210国道西万三级路典型路段建模生成三维模型的基础上,组织53名驾驶人员在虚拟仿真实验室中对虚拟三级路进行现场认知评价试验。采用模糊统计的方法对评价试验得到的795组数据进行分析处理,建立虚拟三级路安全性认知因素的模糊评价隶属函数。采用计算虚拟和实测道路模糊评价隶属函数的贴近度的方法,与基于实际道路的三级路安全性认知因素的模糊评价隶属函数对比,证明虚拟现实技术在驾驶员道路安全感认知评价研究中的可行性。The present paper aims to introduce our computer simulation method on how to reach the harmony among the variety of factors while a driver is working with his ear or truck on the highway, such as his personal psyche, the road environment, and his final road safety. In an integrated operation system of DVR （drive-vehicle-road and the environment）, needless to say, the driver acts as the chief factor in affecting the road traffic safety, including his own information of the road conditions and his mobile surroundings. The virtual simulation model of ours has been done based on the data taken from a typical section of G210 Xiwan Class Ⅲ highway in a virtual reality in a cyber space and the driver＇ s personal experience assessment of the road safety has been done with the Muhigen Creator. In our virtual simulation process, we have calculated and analyzed all the main influential factors that may bring about the likely dangers for a driver＇ s safety. First of all, we have organized 53 drivers of different age groups, and then set up the field perception evaluation tests in a virtual simulation lab of the combined operation of DVR （drive-vehicle-road and environment）. Through the simulation, we have assorted the test data from the drivers so as to make sure to what extent each factor may affect his road safety. The fuzzy virtual simulation method has been realized on the basis of calculating all the likely-to-affect the driver＇ s safety data. According to the statistical data of 795 parameters and the distribution of the assessing indexes＇ influence on the drivers, this simulation has proved to be helpful to define the relevant position or order of an affecting factor against the fuzzy subset, which can be well conformed to the actual road situation. And, finally, the method can be made to be highly approximate to the results of actual road incident investigation. Therefore, the given method here suggested can be made feasible in treating actual road safety assessment practice in addition to its esthe
