客运专线列车开行模式确定方法

Train Operation Mode Decision Method of Dedicated Railway Passenger Line

针对快速客运网背景,将列车开行模式问题定位为列车运行区段与列车类别的协同优化确定问题.通过对列车开行模式类型的分析,提出以运输效用为核心的客运专线列车开行模式确定方法.分析列车开行模式的适用条件,研究列车发车间隔、技术成本系数与旅客时间价值三类因素作用下列车开行模式选择的临界水平.应用数值模拟方法,对路网范围内两类列车开行模式方案进行对比分析.模拟试验的结果显示:列车通达运行范围以技术条件为界的开行模式方案换乘次数较少,平均直达里程较长,且列车无欠速运行.

By analyzing the train operation mode type,a decision method based on transportation utility is presented,applicable train operation mode condition is analysed,and critical level of train operation mode application considering interval time,technology cost coefficient and passenger time value is studied.By using numerical simulation,two schemes of train operation modes on network level are compared and analysed.Simulation experiment results show that the scheme with train running on lines with same technology conditions exhibits fewer transfer times,longer average nonstop distance without speed loss during running.
