中文摘要： 某个区域路网的交通状况通常会受到相邻及不相邻区域路网交通状态的影响，比如快速通道能使一个区域的交通状态迅速影响到空间不相邻区域路网的状态。本研究提出"两箱通道系统"对路网交通状态的传导速度、传导能力等机理进行研究，相对于已有基于路段层面的状态传播研究，可大幅降低全网分析的复杂性；并克服宏观基本图理论对路网状态传导过程分析不足的局限性。研究将分析描述路网状态传导的现象，提炼联系通道（区域）的拓扑特征和交通特性；基于宏观基本图理论和交通动力学理论，构建路网状态传导模型和演变模型，进而解析联系通道（区域）的传导速度、传导能力和蓄流能力对路网状态传导影响的机理；最后通过实测数据对模型进行验证。研究成果可为路网间甚至不同交通方式间状态传导理论提供理论框架和分析方法，也可为联系通道（区域）的规划、建设和管理提供依据，为路网状态预警、管控和需求管理提供支持。

英文摘要： The traffic status of a road network is influenced by the status of not only adjacent region but regions far away. For example, traffic status can be influenced quickly by the status of regions far away through rapid traffic channel. Two-bin-channel system is proposed to study the conduction velocity and conduction ability of road traffic, the complexity can be reduced in contrast to the previous studies which mainly concentrated on traffic status transmission within a link or among links. The limitation of Macroscopic Fundamental Diagram theory can be also solved for the conduction process can be studied in detail with Two-bin-channel system. The representation of road network conduction will be studied with data mining technique and the topology and traffic characters of contact channel will be analyzed; conduction model and evolution model of road network will be developed with Macroscopic Fundamental Diagram theory and traffic flow theory. The mechanic of conduction velocity and conduction ability together with storage ability of contact channel (region) to traffic status conduction of road network will be studied in detail; the result will be validated with field data. The outputs of the project could provide theoretical framework and methodology for not only conduction theory for road network but conductio
