摘要
为提高高速铁路列车准点率,降低高速铁路列车晚点带来的安全隐患,探究高速铁路列车晚点规律,以国内某地区高速铁路沿线4个调度台的列车运行实绩数据为基础,分析其晚点水平、晚点时分分布、增晚分布等晚点指标频率;应用统计学方法—皮尔逊相关系数法和R语言编程工具,探究晚点指标的相关性,得出该高速铁路列车晚点特点及规律。结果表明:上述方法可以得出高速铁路列车晚点规律,在实际工作中可用于降低晚点率,消除安全隐患。
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.
