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.
