城市干道路段交通流速度-流量关系模型研究

结合城市干道交通流为间断流的特点,主要研究了城市干道交通流速度-流量关系。通过对实测数据的统计分析,分析城市干道路段速度与流量之间的关系,采用分段建模的方法,建立了城市干道速度-流量关系模型,对模型的结果进行了分析。可为通行能力、服务水平的研究以及交通仿真参数的修订提供理论依据,并为城市交通规划设计、管理及控制提供技术支持。

Study of Speed-Flow Relationships Model on Urban Artery Roads

This paper mainly studies the speed-flow re-lationships of the urban artery roads,combining with the character of disconnect traffic flow on urban artery roads.Using the survey data from urban artery roads, speed-flow model of urban artery roads is established by analyzing the distribution of the scatter diagram and using subsection modeling method,and the results of the model are analyzed.The results of this study can be used to provide support and reference for traffic capacity, level of service,revising the characters of traffic simulation, urban traffic planning,design,management and control of Chinese urban roads.
