摘要
交通仿真是对交通事件和交通管理策略进行分析和评估的有效手段之一。为保证仿真结果的准确性,必须对路网特征进行细致的描述。对于城市路网,其拓扑关系复杂,路口渠化设计多样。如果在仿真中引入调用OpenFlight API进行辅助建模技术,用户就能快速对路网进行创建和修改。文中介绍了OpenFlight格式以及OpenFlight API,并对基于三维视景仿真的城市交通仿真系统调用OpenFlight API进行辅助建模的关键技术进行了探讨。进行实例研究,取得了较好的效果。
Traffic simulation is an effective measure to analyze and evaluate traffic incident and traffic management strategy. In order to ensure the accuracy of simulation results, the network features must be described in detail. For urban network, its topology relationship is complex and drainage design is diverse. If the auxiliary modeling technology is used by transferring OpenFlight API in the simulation, the users can quickly create and edit the network. The OpenFlight form and OpenFlight API were introduced. The key technologies of auxiliary modeling transferring OpenFlight API in the urban traffic simulation system were discussed. Finally, some case studies were carried out, which achieved good results.
