摘要
虚拟道路试验技术围绕虚拟试验技术和驾驶员道路安全感认知评价研究,首先定性评价了虚拟道路试验技术的可行性。然后,采用MultiGen Creator仿真建模软件对210国道西铜一级路进行三维建模并实施场景驱动,组织53名驾驶人员在虚拟仿真实验室中对虚拟一级路进行现场认知评价试验,以模糊数学为工具分析处理评价试验得到的424组数据,建立虚拟仿真道路要素对模糊认知评语子集的隶属函数。并与基于实测一级路安全性认知因素的模糊评价隶属函数对比,在绘制虚拟与实测一级路安全性认知因素的模糊评价隶属函数曲线对比图的基础上,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,定量评价证明了虚拟道路试验技术的可行性。
The virtual road test technology combines the virtual test technology with the perception assessment of drivers＇ road safety. At first, this study appraises qualitatively the feasibility study on the virtual road test technology. Then, this study gets 3-D road and scene modeling in the Multigen Creator based on the typical section data of G210 Xitong Class I Highway. This study organizes 53 drivers who are in different age phases, puts up the field perception evaluation tests in the virtual simulation laboratory of combined operation of DVR （driver-vehicle-road and environment）. According to the statistical data of 424 parameters and the distribution of the assessing indexes＇ influence on drivers, the relevant membership functions of virtual simulation road＇s factors against the fuzzy subset are ensured, and the assessment of actual road is contracted. Finally, using the method of computing approximation, the results of virtual road tests are close to the results of actual road tests is proved, and the virtual reality technology is feasible in the assessment study on drivers＇ road safety is quantitatively proved.
