交通模型是城市交通工作中重要的分析工具,为城市交通规划、设计、管理以及政策制定等提供了定量支撑。随着城市交通问题的日益复杂化,交通模型的种类也在不断增加,不同的模型其建立的基础以及适用范围都不尽相同。本文在广泛研究国内外各类交通模型发展与应用情况的基础上,结合乌鲁木齐市的实际需求,提出“宏观-中观-微观-节点”四层次综合交通模型体系框架,选择模型体系发展的技术路线,明确不同种类的模型在体系中的定位以及适用范围,并提出不同层次间模型的数据交换需求。
Traffic model is an important analysis tool in urban traffic work, which provides quantitative support for urban traffic planning, design, management and policy making. With the increasing complexity of urban traffic problems, the types of traffic models are also increasing. Different models have different basis and scope of application. Based on the extensive research on the development and application of all kinds of traffic models at home and abroad, the paper puts forward the framework of four-level integrated traffic model system of “macro-meso-micro-node” combining with the actual demand of Urumqi city, chooses the model system development The technical route of different types of models clear positioning in the system and the scope of application and proposed data exchange between different levels of the model needs.
