摘　　要：针对道路交通标志标线视认性静态测试不足和动态测试过程工作繁重,设计由车辆、场景生成子系统、声响模拟子系统、驾驶行为测试子系统、虚拟仪表子系统,试验信息管理子系统等构成的基于半物理模型汽车模拟器的道路交通标志标线虚拟测试系统,探讨利用虚拟现实VR(VirtualReality)技术进行车辆运行时各种动态道路交通环境场景生成关键技术,提出了动态道路场景生成控制参数车辆运行速度和驾驶员视角的建模方法,论述了测试系统试验管理软件应具有的功能,展望了道路交通标志标线视认性主观评价方法和基于驾驶行为的道路交通标志标线视认性建模等内容。As the static testing has many shortages and the process of dynamic testing is complicated, a virtual system for the visibility of road signs and markings is designed based on driving simulators. This system consists of the testing car, sub-system of traffic scene simulation, sub-system of sound simulation, sub-system of driver behavior monitoring and sub-system of information management testing. Traffic scenes created by Virtual Reality (VR) technology are discussed. A modeling method for controlling the car speed and driver views is presented. Functions of the management software in the testing system are analyzed. Subjective evaluation methods of road sign and marking visibility are given. The prospect of the modeling of this visibility model based on driver behavior is discussed.
