摘　　要：为研究区域多制式轨道交通网络耦合评价方法,首先,在复杂网络理论的基础上,对交通路网进行可视化的拓扑研究,求解相应复杂网络中的重要指标;其次,研究网络中关键节点的识别方法,建立耦合评价指标体系,并运用灰色关联法对节点进行排序和鲁棒性分析;再次,提出一种耦合协调度评价指标体系,融合熵权法将各个指标的权重求解后进行耦合协调度的计算与分析;最后,以北京市多制式轨道交通网络为例进行验证分析,并从网络耦合角度提出几点建议。研究结果表明:北京市多制式轨道交通网络耦合后的综合协调指数T_(3)=0.6576,耦合度C_(3)∈[0.5,0.8],各系统之间处于不断磨合并趋于良性耦合的状态下;同时,耦合网络的协调度D_(3)=0.7125,说明耦合网络属于高水平耦合协调下的较为协调的阶段,还应进一步加强节点之间的联系。To study the coupling evaluation method of regional multi-modal rail transport networks,firstly,on the basis of complex network theory,a visual topology study is performed on the traffic road network to determine the key indexes in the corresponding complex network.Secondly,the problem of the identification of key nodes in the network is explored to establish an evaluation index system for the coupling mechanism,and the grey association method is applied to rank the nodes and evaluate their robustness.Thirdly,a coupling coordination evaluation index system is proposed,and the weight of each index is determined by using the entropy weight method to calculate and analyze the coupling coordination degree.Finally,a case study of Beijing’s multi-modal rail transport network is used for validation and analysis,and several suggestions are made from the perspective of network coupling.The study results indicate that the Beijing’s multi-modal rail transport network exhibits a comprehensive coordination index T_(3)=0.6576,a coupling degree C_(3)∈[0.5,0.8].This suggests that the systems are in a state of continuous friction,tending toward a harmonious coupling state.Additionally,the coordination degree D_(3) of its coupling network is 0.7125,signifying a high level of coordination,with potential for further enhancement to strengthen inter-node connections.The link between the nodes can be further strengthened.
