Carrying Capacity of Stations under Express/Local Operation of Urban Rail Transit

Abstract

Abstract:

Express/local operation is an important method for regional rail transit, so research on the effects of different modes of express/local operation on stations can provide instructions for operational enterprises. This paper studies the technical conditions for express/local operation of equilibrium departure without overtaking, non- equilibrium departure without overtaking, and non- equilibrium departure with overtaking, and analyzes the effects of different types of express/local operation on stations and the corresponding deduction coefficients. The results show that when the operation mode changes from equilibrium departure without overtaking to non- equilibrium departure without overtaking and non- equilibrium departure with overtaking, the maximum number of stations skipped by express trains decreases; when the three modes have the same number of stations skipped by express trains, the frequency of trains increases in order, and the deduction coefficient decreases in order, which means the effect of the mode on carrying capacity of stations decreases in order.

Key words: urban traffic, regional rail transit, express/local operation, overtaking, carrying capacity

摘要：

快慢车是城市轨道交通市域线常用的组织形式，研究不同快慢车运营模式对车站通过能力的影响，能够为运营企业开行快慢车提供参考.本文考虑列车追踪间隔时间约束，研究无越行均衡、无越行非均衡、有越行条件等3 种快慢车运营模式的开行技术条件，得到快慢车运营组织对车站通过能力的影响及快车对慢车的扣除系数.案例结果表明：相同发车频率条件下，无越行均衡发车、无越行非均衡发车、有越行条件下的快车最大跨站数量逐渐增加；相同快车跨站数量条件下，无越行均衡发车、无越行非均衡发车、有越行条件下列车最大发车频率逐渐提高，快车对慢车的扣除系数逐渐减小，说明以上3 种模式对车站通过能力的影响依次减小.
