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 is based on the research of virtual test technology and driver road safety awareness evaluation. First, the feasibility of virtual road test technology is qualitatively evaluated. Then, using MultiGen Creator simulation modeling software to do 3D scene modeling and scene-driven modeling of No. 210 State Road west copper level road, 53 pilots were organized to carry out on-site cognitive evaluation test of virtual level road in virtual simulation laboratory. The fuzzy mathematics analyzes 424 sets of data obtained from the tool evaluation process and establishes the membership functions of the virtual simulation road elements to the fuzzy cognitive comment subset. And compared with the fuzzy evaluation membership function based on the safety factor of the actual measured level one, on the basis of drawing the comparison chart of the fuzzy evaluation membership function curve of the cognitive factor of the safety of the first level and the actual measured level, the virtual and measured road Fuzzy approach to evaluate the closeness of membership function, quantitative evaluation proves the feasibility of virtual road test technology.
