High-speed railway normalized train working diagram period determination method

Abstract

The invention discloses a high-speed railway normalized train working diagram period determination method comprising the following steps that high-speed railway stations are divided into multiple levels of nodes; the stop rate and the stop frequency of each level of node are determined according to the stop rate of the lowest level of station; the types and the number of the trains in one period of the normalized train working diagram are determined; and the length of the period T of the high-speed train working diagram is calculated. The passenger flow requirements and the traveling time along the high-speed railway can be fully met, and the requirements of braiding the normalized train working diagram of different high-speed railway lines can be met.

Description

technical field [0001] The invention relates to a period determination method of a standardized train operation diagram of a high-speed railway. Background technique [0002] The train diagram stipulates the order of various trains occupying sections, the arrival, departure or passing time of trains at each station, the running time of trains in each section, the standard of stop time of trains at stations, and the delivery time of locomotives (EMUs). It connects the transportation and production activities of the entire road network into a unified whole. The train diagram is the comprehensive plan of railway transportation work, the basis of railway traffic organization, and is the basis for coordinating various railway departments and units to carry out production activities according to certain procedures. Tools; high-speed railway standardized train operation diagram means that in each time period (T) of the basic operation diagram, the train operation line layout has a ...

Problems solved by technology

[0003]The existing technical schemes for determining the period of standardized train diagrams for high-speed railways mainly include: (1) Roughly determine the period of diagrams based on passenger flow rules and train operating experience; ( 2) Deduce the cycle of the operation diagram through the trial laying of the train operation line during the peak period; the existing technical schemes essentially solidify the standardized operation diagram cycle of different high-speed railways, which are not closely integrated with the characteristics of high-speed railway train operation, and fail to be based on the characteristics of different high-speed railway lines and the passenger flow along the line as the basis for designing standardized operation diagrams; at present, the method of determining the cycle of standardized train operation diagrams is mainly based on experience and simple derivation, solidifying the operation diagram cycle, and the theoretical fulcrum for determining the length of the cycle is relatively weak, which is not consistent with the actual high-speed The combination of railway lines does not consider the key factor of periodic passenger transport products, and it is impossible to optimize product design from its own perspective
