摘要
速度100km/h和120km/h的地铁动车组的逐步采用,将引起越行的发生,并对地铁线路的站点分布、能力的利用、不同速度动车组的旅行速度和开行数量比例等方面产生一定的影响。为此,研究了最小追踪间隔时间与最大站间距之间的关系,确定了较高速度动车组的开行比例范围,并讨论了较高速度动车组对能力的影响,以及较低速度动车组旅行速度的变化情况。
The increasing operation of 100km/h and 120km/h EMUs in metro system shall lead to occurrence of overtaking and shall have certain influence upon distributeon of stations, utilization of capacity, travel speed of EMUs designed for different speeds, proportion between the EMUs put into service. Therefore, the proportion range of the higher speed EMUs put into operation is determined through study- ing the relationship between the minimum headway and the maxi- mum distance between the stations. Also discussed are the influence of the EMUs designed for the higher speed upon the traffic capacity and the variation of the travel speed of the EMUs designed for the lower speed.
