Abstract: In order to improve its on-time rate and reduce the security threats the high-speed train lateness poses,the lateness regularity of high-speed trains was explored. Based on the train operation data of four dispatching stations along the high-speed railway in a certain region of China, the frequency of its late indicators was analyzed,such as late level, late time distribution and increase-late distribution. Statistical methods-Pearson correlation coefficient and R language programming tool wereappliedto explore the correlation of its late index, and obtain the late characteristics and regularity of the high-speed train. The results show that the above method can be applied to obtainingthe late regularity of high-speed railway so as toreduce its lateness rate and safety hazards in actual traffic control work.

Key words: high-speed railway, train punctuality rate, performance data, Pearson correlation coefficient, late regular
