考虑乘客流影响的列车运行调整难点研究

本文针对基于通信的列车控制(CBTC)系统中列车运行的特点,研究了运行调整中的难点问题-晚点传播,即在前行列车发生初始延误的条件下,引起后行列车或其自身的后效晚点现象.分析了乘客流对列车晚点的影响,在建立列车停站模型时,考虑乘客流的影响,提高该系统的可行性.建立了以列车总晚点时间为优化函数的运行调整模型,最后利用matlab中的遗传算法工具箱对此进行求解,实验结果显示了该模型应用于实际运行调整时的可行性和有效性.

Study on difficulty of train operation adjustment under influence of passenger flow

This paper aimed at the characteristic of train operation in CBTC System and studied the difficulty of train operation adjustment-delay transmission,it caused the following trains and the train itself delay under the condition of the initial delay of the first train.The paper also analyzed passenger flow on the impact of delay trains.When the train stop model was established,it was taken into count the influence of passenger flow.The feasibility of the System was enhanced.At last,the paper constructed the operation adjustment model which put the total delay time as optimization objective and used the matlab Genetic Algorithm toolbox to solve it.Simulation results verified the effectiveness and feasibility.
