摘　　要：针对网络换乘性能,提出了计算城市轨道交通网络换乘次数的矩阵算法。利用图论建立网络数学模型,利用可达矩阵计算了网络拓扑结构的平均换乘次数。在此基础上考虑客流量的影响,通过挖掘地铁AFC(自动售检票)数据,计算按客流量加权的平均按乘次数。定义网络换乘效率为实际按乘次数与理论换乘次数的比值,并以北京地铁为例进行计算。计算结果验证了算法的有效性。In order to investigate in the network transfer per-formance, a matrix algorithm is proposed to calculate the average transfer times of urban rail transit network. A mathematical model about transit network is established based on graph theory, and the average transfer times of topology network is calculated by using reachable matrix. On this basis, with a consideration of passenger flow, and by way of AFC data mining, the practical average transfer times on the subway are calculate. The transfer performance is defined as the ratio of practical average transfer times to theoretical transfer times. Taking Beijing subway as an example, the effectiveness of this algo-rithm is verified.
