摘　　要：随着城市轨道交通规模扩大,车站数量增加,线间关联愈加密切。在网络化运营条件下,网络结构的复杂性、客流需求分布的不均衡性及列车运行组织方式的多样性,均对城市轨道交通运输计划提出更高的要求,在此提出基于节点重要度的城市轨道交通线网换乘优化方法。基于乘客出行选择行为对路径广义出行费用进行计算,建立基于时空出行网络的客流分配模型;依据影响城市轨道交通节点重要度的因素,提出网络内各区间及线路重要度的计算方法,基于线网内各节点、区间及线路的差异,构建基于节点重要度的城市轨道交通换乘协调优化模型;以成都地铁局部网络为例,验证模型的有效性。结果表明:所提出的协调优化模型将网络内站点、区间及线路3个层面的匹配度总共提升了34.58%,有效地提高了线网运输计划的运营效率。With the rapid development of the scale of urban rail transit networks,the number of stations is expanding,and the connection between lines is becoming closer.Under the condition of network operation,higher requirements for urban rail transit transportation plans have been put forward due to the complicated network structure,the imbalanced passenger flow demand distribution,and the diversified train operation organization mode.Therefore,this paper proposed a transfer optimization method for urban rail transit line networks based on node importance.Firstly,based on passengers’travel choice behaviors,the paper calculated the generalized travel cost of the path and built a passenger flow distribution model based on the spatiotemporal travel network.Secondly,based on factors affecting the importance of urban rail transit nodes,the paper established the calculation method for the importance of each section and line within the network.According to the differences between the nodes,sections,and lines in the network,it constructed an optimization model of urban rail transit transfer coordination based on the importance of nodes.Finally,the paper verified the model effectiveness by calculating the data from the local network of Chengdu Metro as an example.The results show that the proposed coordination optimization model improves the matching degree of the three levels of stations,sections,and lines in the network by 34.58%in total,which effectively improves the operation efficiency of the network transportation plan.
