地铁列车运行延误分析

列车晚点降低了乘客在途时间的可靠性，这是造成城市轨道交通运营和服务质量下降的重要原因，通过分析列车晚点的产生机理和时空特征，可以制定有效的调整和控制措施，提高城市轨道交通系统的乘客服务水平。本文着重分析了地铁列车晚点的产生原因和时空分布特征，为减少列车初始延误发生、控制连带延误影响的防范措施的制定提供依据。

Analysis and Control of Delay of Metro Train

Train delay reduces the certainty of time on train, It is the major reason why the quality of urban rail transit operation and service are on the fall. By analyzing the emergency mechanism and space-time characteristic, it is possible to establish effective control measures to improve service. This article analyses the reason and space-time characteristic of metro train. At last, from the aspects of preventing fault and emergency arrangement, this paper presents some means to reduce the occurrence frequency of train initial delay and keep the influences of related delay af acceptable level.
