Study On The Compilation Of Periodic Train Diagram Of Intercity Railway

With the rapid development of China's economy,regional linkage significantly enhanced,with big city as the center of the city group has gradually developed,for cities communication's convenient,intercity rail transportation needed to be built,give full play to the advantages of intercity railway,but China's current research on transportation organization mode for intercity railway is not perfect,therefore based on the research of intercity railway transport organization mode,Cyclical train diagram of the intercity railway needed to be explored.This paper mainly studies the contents of the following aspects.First,this paper summarizes the status quo of Intercity Railway in China,from two aspects of theory and reality to explain the significance of this study,through the research on the model and algorithm of the foreign literature in the period of train diagram summary,points out that it is fully applicable to domestic,through research of cycle operation the figure in the high-speed railway,city rail,intercity rail,points out the weakness of the study,clear the research direction and content.Secondly,this paper gives a definition of train running cycle and intercity railway,the characteristics and the train diagram of the cycle is analyzed in detail.By comparing with the city rail,passenger dedicated channel type,the characteristics of intercity railway is summarized,and the operation characteristics of intercity railway are summarized,and the Beijing Tianjin intercity as an example to analyze the applicability of part of the intercity railway in our country on the periodic train diagram.Thirdly,this paper gives a detailed introduction to the compilation method of the cyclical operation chart of intercity railway.The whole preparation process of periodic train diagram is given,and the preparation program in which the key part of rush hour train diagram are summarized,pointed out that the preparation of periodic train diagram needs to use the diagram to determine the cycle,the train interval to order,determine the initial distribution diagram and operation line conflict resolution and key technology.Then,based on planning theory of periodic events,consider the train diagram to the periodic constraint,moments of stop time constraints,the safe interval constraint,equilibrium constraint,to train collision constraints,EMU travel time as the target model,operation cycle of train two-way also considered EMU connection constraint and constraint periodic working diagram,to establish minimum connecting time of EMU continuous periodic train diagram adjustment model based on the target,departure time of the train operation diagram of feedback adjustment.At last,this paper introduces the design of a 9 station as an example,using CPLEX to train departure time for drawing the peak cycle graph,and the peak cell cycle map pumping line draw flat peak cycle graph,finally use the adjustment model to adjust the running time of train operation drawing after adjustment.
