【摘要】 通过对现有城市道路模型的分析,提出构建城市道路的三维仿真模型。利用ArcGIS软件,针对道路几何模块,建立了基于节点、路段、节段和路面的二维和三维模型,同时也兼顾了交通检测模块和控制管理模块。与其它道路模型比,该模型能更准确、细致地反映道路网的拓扑关系和道路几何条件,从而为交通仿真模型真实地反映路网交通状态奠定了基础。更多还原

【Abstract】 After analyzing of current urban traffic model, the new urban traffic of three- dimensional simulation model is put forward. The two and three-dimensional models with node, link, segment, lane as fundamental elements are made detailed. At the same time, the models of traffic inspection and control are introduced too. As compared with forepassed urban traffic model, these models give a more accurate and detailed description of the road network topology and geometry, and lay a good foundation for the traffic simulation models to describe the network traffic state more realistically.更多还原
