摘要：阐述了运用VISSIM仿真系统构建3D交通环境的方法和过程，为VISSIM仿真系统的应用提供参考。介绍了仿真背景图、VISSIM的3D信号灯以及3D交通环境的要素和实现方式。利用VISSIM的可选模块V3DM建模时可分为两类模型，重点介绍了第I类3D模型的建立。总结了避免发生模型错位的注意事项和解决方法，即在缺少背景矢量文件的情况下，利用Adobe PDF虚拟打印机将路网信息打印到pdf文件，并通过Illustrator软件输出得到仿真路网的dwg文件。以武汉市建设大道为例，实现了逼真的3D交通环境效果。

Abstract：To provide reference for application of VISSIM simulation, this paper sets forth the method and process of structuring a visual 3D traffic environment by means of VISSIM simulation system. In particular, the paper also introduces elements and realization modes of simulated background, 3D signals of VISSIM and 3D traffic environment. With the available module of VISSIM, V3DM, two types of models can be built. The paper focuses on introducing the establishment of the first type of 3D model. It concludes with the instructions and solution for avoiding any dislocation of the model: i.e., without the background vector file, Adobe PDF virtual printer can be used to print the road network information to PDF file and the Illustrator software is used to export the dwg file of the simulated network. A 3D traffic environment is visualized with an example of Jianshe Avenue in Wuhan.
