本文详细介绍了港珠澳大桥三维动态交通仿真平台的设计与实现,包括平台总体架构、平台功能设计、三维模型的建立和平台实现方式。平台以港珠澳大桥设计文件为蓝本,借助于UC-WinRoad 4.0和3D-Max软件建立大桥的三维模型,以VISSIM微观交通流仿真软件为依托,运用C#语言开发大桥三维动态仿真平台。最终开发了与港珠澳大桥深度融合、能够实时接入交通流数据并实现三维动态仿真显示的交通仿真平台,平台能够实现事件条件下多种交通组织方案优劣的比选,全方位地实现了微观交通仿真软件在高速公路营运管理方面的升级。
This paper introduces the design and realization of the three-dimensional dynamic traffic simulation platform of Hong Kong-Zhuhai-Macao Bridge in detail, including the overall structure of the platform, the functional design of the platform, the establishment of the three-dimensional model and the realization of the platform. The platform is modeled on the design document of Hong Kong-Zhuhai-Macao Bridge. With the help of UC-WinRoad 4.0 and 3D-Max software, a 3D model of the bridge is established. Based on the VISSIM micro traffic flow simulation software, the C # language is used to develop 3D dynamic simulation platform of the bridge. In the end, the traffic simulation platform, which is deeply integrated with Hong Kong-Zhuhai-Macao Bridge, can access traffic data in real time and realize 3D dynamic simulation display, is able to realize the comparison and selection of the advantages and disadvantages of various traffic organization schemes under the event conditions. Micro-traffic simulation software in the highway operation and management of the upgrade.
