摘　　要：为了更合理表达旅客对城际铁路不同等级列车的选择行为,本文根据城际铁路旅客列车的开行特点划分了列车等级,并对旅客分类,定义客流留存率以建立城际铁路客流的动态分配模型。分配模型表达预测客流在某一开行方案的不同等级列车之间分配和预测客流流失到其他交通方式的过程,并定义最小间隔时间解决列车开行时刻和客流预测中的广义费用问题。在客流动态分配模型的基础上构建目标方程和约束方程形成列车开行方案优化模型。最后,以广清城际铁路为实例,运用开行方案优化模型生成系列开行时刻及列车等级,证明了优化模型的有效性。In order to rationally indicate the selection of different train ranks by passengers, and according to the train operation characters, the trains and the passengers were classified. Then, the passenger flow reserve rate was defined. After then, a passenger flow dynamic assignment model was established, with which the forecasted passenger flow assignment among the different train ranks of a operation scheme and the process of the forecasted passenger using the other transit ways instead of trains could be indicated .To get the train departure time and the generalized cost of the forecast passenger flow, a minimum train interval time was defined.Finally,based on the model, the objective function and its constraint conditions formed the optimal model for the train operate scheme. An example of Guangqing intereity railway was given to examine the model＇s effectiveness.
