The invention discloses a station importance evaluation method and device in rail transit, belongs to the technical field of traffic networks and propagation dynamics, and are used for solving the problem that an evaluation result is greatly different from the actual situation due to the fact that spatial and temporal characteristics of passenger flow are ignored in cascade fault evaluation in existing rail transit. The station importance evaluation method comprises the steps of: determining a y+1 state value of a normal node in an upper-layer passenger flow network according to a weight of anedge in an upper-layer passenger flow network within a time period t and a coupling coefficient of the upper-layer passenger flow network in y+1; determining a y+1 state value of the normal node in alower-layer track structure network according to a connection state of an initial fault node and nodes adjacent to the initial fault node and a coupling coefficient of the lower-layer track structurenetwork, and when determining that the nodes of a double-layer rail transit network are all fault nodes within the y+1 moment, determining an evaluation result of the initial fault node according tothe number of the nodes of the double-layer rail transit network and the number of the fault nodes when the nodes of the double-layer rail transit network are all fault nodes.

    本发明公开了轨道交通中站点重要性评估方法及装置,属于交通网络和传播动力学技术领域。用以解决现有轨道交通中级联故障评估存在忽略客流的时空特征而导致评估结果与实际情况相差较大的问题。该方法包括:在y+1时,根据时间段t内上层客流网络中边的权重、上层客流网络的耦合系数确定正常节点在上层客流网络中的y+1状态值;根据初始故障节点和与初始故障节点相邻节点的连接状态、下层轨道结构网络耦合系数确定正常节点在下层轨道结构网络的y+1状态值,当在y+1时刻内确定双层轨道交通网络的节点均为故障节点时,根据所述双层轨道交通网络节点的数量以及双层轨道交通网络的节点均为故障节点时故障节点的数目,确定初始故障节点的评估结果。
