摘  要：地铁列车行车密度高、追踪间隔短，调度员在突发情况下的反应时间、抉择越来越少，行车调整难度大幅提升。该文基于既有地铁运营条件，提出适用于贵阳地铁1号线不同晚点程度情况下“先压后赶“的运行调整方法。实践证明，该方法可以有效提高调度员应急处置效率，减小晚点事件对运营的影响。

Abstract： The metro train has the advantages of high traffic density and short tracking interval， the response time and choices of dispatchers in sudden situations are less and less， and the difficulty of train adjustment is greatly increased. Based on the existing subway operation conditions， this paper puts forward the operation adjustment method of "pressing first and then catching up"， which is suitable for Guiyang Metro Line 1 with different degrees of delay. Practice has proved that the method can effectively improve the emergency response efficiency of dispatchers and reduce the impact of late events on operation.

Keywords： urban rail transit; train delay; emergency response; traffic adjustment; "pressing first and then catching up"
