考虑路段转向流量和破坏排队的动态网络装载问题

摘要

In order to model the multiple congestion conditions spillback queue on a link, dynamic network model with spillback queue and turning capacity limiting is proposed. The node flow assignment model considering spillback-queue is divided into two classes: one considers the link flow include only one flow state, the other considers the ling flow can include multiple flow ,queue state. The node flow model considering multiple queue and flow conditions on a link is presented. The simulation results show the model can demonstrate the multiple traffic conditions on a link.%建立一个考虑路段转向流量限制和破坏排队的动态网络装载模型;考虑无力排队影响的节点分流模型主要分为两类:一类认为路段只有一种交通状态;另一类允许路段上有多种流量状态存在,可以分别处理不同下游分支路段的排队状况.文中给出一种在一个路段上考虑多种排队状况的节点分流模型.并在一个著名的路网中进行了仿真试验,结果表明模型的有效性和正确性.
