摘要
结合城市干道交通流为间断流的特点,主要研究城市主、次干道交通流速度-流量关系曲线,并采用迭代对分区间法得出各个车道的推荐通行能力值。研究结果可为主、次干道通行能力、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。
It studies the speed-flow relation curve of urban main and minor roads combining with the characteristics of disrupted traffic flow on urban arterial roads.The iterative halve interval method is used to obtain the recommended value of traffic capacity.The results of this study can be used to provide support and reference for studying the traffic capacity and level of service of the urban arterial roads,and theoretical basis for revising traffic simulation parameters,as well as technical support for the planning,design,management and control of urban traffic.
