摘要
通过对城市轨道交通系统中列车间隔的分析,提出了影响列车间隔的3大因素:安全间距,车站停留时间和运行裕量。在此基础上推导固定自动闭塞和移动自动闭塞系统下列车间隔的计算公式。通过对两公式的比对,得出了移动自动闭塞系统能够缩短列车的运行间隔,提高线路的通行能力。
This paper analyzes train headway in urban rail transport system, and puts forward three factors affecting train headway including safe spacing, cutoff interval and traffic flow. On this basis, computation formulas of train headway under fixed automatic block and moving automatic block are deduced in the paper. By comparing the two formulas, the paper concludes that moving automatic block can reduce the train headway and improve the transportation capacity.
