Urban rail transit cross-station parking and starting scheme optimization method based on direct passenger flow

Abstract

The invention discloses an urban rail transit cross-station parking and starting scheme optimization method based on direct passenger flow, which comprises the following steps of: starting a train A, a train B and a train C on a line according to different parking schemes, and alternately starting the trains at equal intervals at a starting station; route stations are divided into stations A, stations B, stations C and stations S. The corresponding relations between the trains and the stations are set as follows: the A train jumps from the station A, the B train jumps from the station B, the C train jumps from the station C, and the station S represents full stop of the three types of trains; according to the method, passenger flow OD is divided on the basis of the types of ridable trains, the proportion of each type of passenger flow, the probability of the ridable trains and travel time are studied, a mixed integer programming model with a cross-station scheme and departure frequency as decision variables is constructed, and a genetic algorithm is designed for solving. According to the invention, all passengers can directly pass without override facilities, so that the travel time of the passengers is shortened while the travel speed of the train is increased.

Description

technical field [0001] The invention relates to the technical field of urban rail transit traffic organization, in particular to a method for optimizing an urban rail transit cross-station stop and go plan based on direct passenger flow. Background technique [0002] In recent years, with the gradual improvement of my country's urban rail transit network, problems such as high passenger flow intensity, uneven temporal and spatial distribution, and long passenger travel distances have become increasingly prominent. Taking Beijing Rail Transit as an example, by the end of 2019, the average daily inbound traffic of Beijing Rail Transit exceeded 6 million passengers, and the average travel distance per capita exceeded 16km. At present, subways in major cities still generally use station stops. Under this operating mode, long travel distances mean more stops. Calculated on the basis of an average station distance of 2km, the number of stops per capita of Beijing rail transit is ...
