High speed railway main line train operation scheme optimizing method and system

Abstract

The invention discloses a high speed railway main line train operation scheme optimizing method and system. According to the invention, a high speed railway main line train operation scheme is taken as an optimization object. Current high speed train marshalling characteristics and train starting and destination arriving capability limitation are taken into account, on one hand, in order to ensure that the transportation capability of trains of different sections of lines meets sectional passenger transporting demands, train operation paths achieving the optimal match between the transportation capability and passenger flow demands are searched and starting and destination arriving stations and departure frequency are determined; on the other hand, intermediate train stops are arranged according to boarding and alighting passenger flow and OD passenger flow, namely, matching between the OD passenger flow and the train service frequency is realized through setting a train stop scheme reasonably. An optimization model and a solution algorithm obtained in two layers including capability matching and service frequency matching are in close combination with high speed railway transportation organization and passenger transportation organization characteristics. The train path scheme and the train stop scheme are reasonable. The optimization method is good in practicability.

Description

technical field [0001] The invention relates to the field of train running schemes on a main line of a high-speed railway, in particular to a method and system for optimizing a running scheme of trains on a main line of a high-speed railway. Background technique [0002] my country's high-speed railway has been networked and operated, and the high-speed railway train operation plan can be divided into two types: main-line trains and cross-line trains on each high-speed railway line. The train operation decision of Beijing-Guangzhou, Beijing-Shanghai, Beijing-Harbin and other busy passenger corridors has an important impact on the network train operation plan. In order to adapt to the high-density passenger flow of the main line, the trains of the main line have the characteristics of high operating density and prominent public transportation characteristics, which are significantly different from cross-line long-distance trains that emphasize transportation capacity in terms...

AI Technical Summary

Problems solved by technology

However, in terms of train stop setting, there are currently the following problems: 1) The purpose of train stop setting is not clear, and the service frequency of some intermediate stations along the way is reduced; Poor benefit

There is a clear quantitative relationship between the stop time and frequency of high-speed trains in Japan and other countries, and the service passenger flow. Each train class has a clear range of stop numbers, but there is a lack of similar stop setting standards.
