摘　　要：高速铁路网络条件下,结合高速铁路旅客出行需求、客流结构和不同出行模式,将客流合理分配到高速铁路列车流,对提升列车能力利用率、提高换乘旅客出行的便利性和服务水平具有重要意义。构造高速铁路换乘服务网络,根据换乘服务网络特征,得到网络各类型弧段的阻抗函数,在此基础上提出基于高速铁路换乘服务网络的随机用户均衡模型,利用梯度投影算法对模型求解。算例通过与未考虑换乘条件的方法比较,结果表明该模型可以在一定程度上提升列车区间平均上座率。Under the high-speed railway network condition, reasonably assigning passenger flow to train flow is significant to improve train capacity utilization rate, transfer passenger travel convenient and service level combining with high-speed railway passenger travel demand, passenger flow construction and different travel mode. With the construction of the transfer service network, according to the characteristics of the transfer network, the impedance function for each kind of arcs in the network can be obtained. Based on this, the high-speed railway transfer service network stochastic user equilibrium model is proposed and solved by gradient projection algorithm. Through an example, the model can be used to improve the average load rate of the train comparing to the method without considering the transfer condition.
