High-speed rail train driving method based on section profile passenger flow

Abstract

A high-speed rail train driving method based on the section profile passenger flow includes the following steps that high-speed rail station information is obtained through a high-speed rail network operating system firstly, and a high-speed rail network is divided into a plurality of sections; the stop modes of high-speed rail trains are determined according to multiple grades; the O-D (origin-destination) demands of each section are classified according to the stop modes; the historical data about the actual O-D demands of each section are obtained, and the time varying demand of each type of O-D in each section is obtained through a linear second exponential smoothing prediction method; on the basis, the driving scheme unit of each section is made according to the sequence of the trains from the high grade to the low grade; all the driving scheme units are spliced and combined to form an initial train driving scheme; and finally, the scheme is adjusted to meet various restraint conditions and optimized through a simulation annealing algorithm, and each high-speed rail train is driven according to the optimization result. The high-speed rail train driving method based on the section profile passenger flow takes the benefits of the high-speed rail system and the passenger demands into account, and can improve the running benefits of the high-speed rail system.

Description

technical field [0001] The invention relates to the field of high-speed railway transportation, in particular to a method for running high-speed railway trains based on section-section passenger flow. Background technique [0002] With the continuous advancement of the country's "medium and long-term railway network planning" and the 2008 adjustment plan, Beijing-Guangzhou, Beijing-Shanghai, Harbin-Dalian and other high-speed railway lines have been built and put into operation, initially forming a high-speed railway network. Under the high-speed railway network operating environment, passenger travel service level and train operation efficiency can be greatly improved, and railway transportation resources can be effectively utilized. At the same time, it also increases the difficulty of organizing high-speed railway network train operations. Aiming at the demand of the railway passenger transport market and passenger flow structure, taking advantage of the advantages of hig...
