The Research on the Train Operation Plan of the Beijing-Tianjin Inter-city Railway Based on Periodic Train Diagrams

The features of the passenger flow,the transportation tasks and the service level of the inter-city railway all differ from those of the existing railway lines.Due to the differences,the train operation plan should adopt the traffic organization mode characterized by periodic train diagrams,because which has such merits as prominent regularity,good flexibility,high efficiency and convenience for passengers to travel.This paper studies the passenger train operation plans based on periodic train diagrams,and considering the profits of the train transportation enterprises and waiting time of passengers,especially the uncertainty of the passenger flow,establishes the chance-constrained model with three specific objectives.Taking the Beijing-Tianjin Inter-city Railway as the background,this chance-constrained model is used to calculate the train operation plan.The calculation demonstrates that,comparing with the single objective model and the determinate model,the multiobjective model reflects facts more reasonably.
