摘　　要：换乘行为是保持轨道交通网络正常运行的关键因素．针对轨道交通网络，提出一种添加换乘因素的网络模型构造方法．首先，根据换乘站点的交汇线路数量N，再裂变出N-1个换乘站点；其次，这Ⅳ个换乘站点相互之间有换乘通道相连，且每条线路通过其中一个换乘站点；最后将构造方法运用到北京轨道交通网络，并通过仿真实验对比分析新旧网络模型的基本参数．结果表明：新建轨道交通网络模型在换乘流量的确定、负荷平均最短出行时间等方面弥补了以往模型的不足．Transfer behavior is a key factor in maintaining normal operation of subway network. A new construction method of subway network model based on transfer behavior is proposed in this paper. Firstly, according to the number of subway lines （N） which pass through the transfer station, this method produces other N - 1 transfer stations. Secondly, there are transfer-channels between these transfer stations and each subway line passes through one transfer station. Finally, this construction method is applied to Beijing subway network, and basic parameters of old and new subway network model are compared through simulation. Results show that： New subway network model makes up for shortcomings of previous model in determining transfer flow and load average shortest transporting time.
