摘　　要：基于虚拟仿真试验技术,在人-车-路(环境)联合运行仿真平台上进行面向公路线形、景观和交通工程设施等设计方案的仿真试验,构建了基于虚拟现实的驾驶人道路安全感评价体系,建立了虚拟一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贴近度的方法,与实际一级路的安全性认知因素的模糊评价隶属函数进行了对比。试验结果对比表明,虚拟和实测一级路的评价结果近似,证明虚拟现实技术在驾驶人道路安全感认知评价中应用的可行性。Based on the virtual reality technology, this paper introduces the simulation tests on the design schemes of highway alignment, landscape, traffic engineering facilities on the visual simulation platform of combined operation of driver-vehicle-road system, constructs the assessment system of road safety, and ensures the relevant membership functions of the simulation. Using the computing approximation, the high approximation to the results of actual road can be made for the incident investigation. The results show that the virtual reality technology is feasible in the assessment research of drivers＇ road safety. 4 tabs, 4 figs, 11 refs.
