Research on the method of overtaking station setting for express/slow train in urban rail transit
With the continuous development of urban rail transit,the transportation organization mode of express/slow trains has gradually become an important strategy to enhance the travel efficiency of passengers and realize the fast and direct service.However,at present,the location and number of overtaking stations are mostly dependent on the process of drawing the operation diagram,and the working efficiency and analyzing accuracy are relatively low.To solve this issue,the article starts from the scenario in which overtaking stemmed from,proposes that the initial departure interval between express and slow trains,the initial departure interval between slow trains,and the engineering cost of overtaking stations are the main factors affecting the location of overtaking stations,and summarizes the rules for setting overtaking stations accordingly,and designs the algorithm for solving the location and number of overtaking stations based on the dynamic enumeration of the relationship of the departure intervals.Nine feasible solutions are obtained through the construction of validation cases to verify the validity and practicability of the theoretical method,which is of great significance in solving the problem of overtaking station setup in the urban rail transit project.
