Subway passenger flow organization method based on major stop parking and multi-station synergistic flow-limiting

Abstract

The invention discloses a subway passenger flow organization method based on major stop parking and multi-station synergistic flow-limiting. The method comprises the following steps: counting the passenger flow characteristic of each station on a subway line; setting a train stopping scheme of the subway line according to the passenger flow characteristic; constructing a space-time transfer model of the train and the passenger according to the passenger flow characteristic of each subway station and the train stopping scheme of the subway line; computing a weighted value of a line multi-station transportation system according to the space-time transfer model of the train and the passenger; dynamically adjusting a decision variable, optimizing integral weighted value of all passengers to obtain an optimal train stopping scheme and the corresponding flow-limiting scheme. Through the adoption of the technical scheme disclosed by the invention, the limitation of isolatedly and statically considering the passenger flow limiting in single station is overcome, the influence of the passenger flow change in each station to the adjacent station is considered, the stations and the line are regarded as an integer so that the passenger flow changes of the whole line is dynamically linked, the method has obvious improvement in comparison with the existing single-station flow-limiting scheme.

Description

technical field [0001] The invention relates to passenger flow organization of urban rail transit. More specifically, it relates to a subway passenger flow organization method based on large station parking and multi-station cooperative flow restriction. Background technique [0002] In recent years, the construction of urban rail transit in major cities in China has developed rapidly, the scale of road network operation has continued to expand, and the passenger flow sharing rate of urban rail transit in urban traffic has continued to increase, which has brought about the problem of insufficient capacity of some lines or stations during morning and evening peak hours , showing that the section where the maximum full load rate of the line exceeds 100% continues to increase, the phenomenon of passenger oversaturation in the station is serious, the platform is crowded, the waiting time is too long, the riding efficiency is low, and passenger safety is threatened.

Problems solved by technology

This measure alleviates the pressure of large passenger flow on stations and lines to a certain extent. However, the time granularity of this measure is relatively large. Different lines and stations have their own flow limits based on experience, and the impact of the flow li
