摘要: 准确衡量高速铁路 (HSR)系统故障的影响,对于提高高速铁路行车调度指挥水平和运营管理质量具有重要意义。基于武汉—广州高速铁路列车运行实际数据,提取故障影响晚点列车运行序列;运用K-Means聚类算法根据故障自身及运行图特征将其聚为4个不同类别,利用5类常见分布模型对训练集影响列车数分布进行拟合;以柯尔莫可洛夫-斯米洛夫(K-S)检验结果为模型拟合优度的比选依据,建立高速铁路故障影响列车数分布模型。测试集数据对拟合模型校验结果表明:测试数据集分布与拟合的最优模型分布一致,所建模型可以用于高速铁路实时调度指挥过程中故障影响列车数的估计。

Abstract: It is of great significance for the influence of high-speed railway disruption to be accurately measured forimproving the real-time dispatching and management abilities of HSR. First, based on the historical train operation records of Wuhan-Guangzhou HSR, delayed train groups caused by disruptions were extracted and a K-Means clustering algorithm was used to classify them into four categories, according to disruption and timetable characteristics. Then, five distribution models were investigated to fit the distributions of the affected train number in different clustered categories. Next, optimal distribution models for the number of affected trains were selected according to Kolmogorov-Smirnov (K-S) test. Finally, verification results show that distributions of the affected train numberin the test dataset were consistent with the fitted optimal distribution models. The fitted models can be used to estimate the number of trains affected by disruptions in real-time dispatching process of HSR.

Key words: high-speed railway (HSR), disruption, affected trains number, K-Means algorithm, distribution model
