城市轨道交通列车延误统计指标及评价指标体系研究

Research on Statistics Index and Evaluation Index System of Urban Rail Transit Delays

列车延误事件的发生是城市轨道交通运营不可靠性的具体表现。在对列车延误事件进行分类的基础上,对引发延误发生的因素进行了分析。建立了一套列车延误事件统计指标,并给出了指标的计算方法。根据这些统计指标构建了单起列车延误事件严重程度的评价指标体系和城市轨道交通线路以及网络的列车延误水平评价指标体系。评价指标体系的建立对于客观评价列车延误事件严重程度以及轨道交通线路和网络的列车延误水平,制定科学的列车延误事件预案和预防措施具有参考意义。

Train delay events are the manifestation of unreliable train operation.In this paper,by classifying train delay events,the factors causing train delay are analyzed to provide a reference for the measurements against train delay.Then,a set of statistical indicators of train delay events is established,the calculation method of the index is given.Finally,according to these statistic indexes,an evaluation index system of train delay severity,rail transit line and network delay levels is designed.The evaluation index system can be used for objective evaluation of train delay,with reference significance for scientific train delay emergency plans and preventive measures according to the evaluation results.
