摘　　要：以道路交通仿真虚拟场景构建理论知识为基础,运用道路线形设计软件———纬地设计新建或改建道路线形,仿真建模软件Multigen-Creator提供的API函数实现道路主体仿真模型的构建,运用地形建模软件Terrain-Vista实现道路仿真模型与地形的无逢连接,虚拟场景驱动软件VSDesign实时显示道路设计参数并实现实时仿真,解决了各软件之间数据的通用问题。提出道路虚拟视景构建方法的技术路线。Based on theoretical knowledge of Traffic Simulation Virtual Scenes, this paper adopts road alignment design software Weidi to design or rebuilt road alignment. API functions provided by the software Multigen-Creator are used to achieve the main road construction, while the Terrain-Vista is used to combine road simulation model with terrain exactly. Furthermore, the virtual scene-driven and real-time display software VSDesign is used to show road design parameters. As a result, various problems of data sharing among different kinds of software are solved. Finally, the technical route of road virtual scene method is presented.
