城市轨道交通列车折返间隔时间研究

城市轨道交通车站的折返能力是影响系统通过能力的主要因素。概述列车折返间隔时间的几种表现形式，包括接车间隔时间、到达间隔时间、发车间隔时间和出发间隔时间，并结合站后折返模式，详细分析各种间隔时间之间的关系。得出选用出发间隔时间作为列车折返间隔时间的结论，并通过仿真对以上分析结果进行验证。

Train turn-back headway in Urban Transit

Turn-back capacity of station was the main factor of affecting the passing capacity in Urban Transit. Several forms of turn-back headway including receiving headway, arriving headway, dispatching headway and departure headway were summarized. Combined with rear turn-back mode, the relation among these headways was analyzed in detail. It was concluded to choose the departure headway as the turn-back headway. The analytical results was validated by simulation.
