Method and system for determining suburban line subway express and slow vehicle stop sequence

Abstract

The invention relates to a method and system for determining suburban line subway express and slow vehicle stop sequence, and the method comprises the steps: determining the importance degree evaluation indexes of stations on the way of a rail transit line, and evaluating the weight of the importance degree evaluation indexes relative to the importance degree of each station on the way through an analytic hierarchy process; and according to the value of each importance degree evaluation index of each station along the way and the weight of each importance degree evaluation index relative to the importance degree of the station along the way, determining the stop weight of each station along the way so as to reduce the travel time of passengers and reduce the operation cost of enterprises as optimization objectives. establising the first objective function and the second objective function of the suburban line fast and slow vehicle stop optimization scheme, adopting the immune genetic algorithm to solve the first objective function and the second objective function, obtaining the suburban line fast and slow vehicle stop optimization scheme. The problems that in the prior art, metro operation efficiency is low, certain waste of passenger travel time and enterprise transportation cost is caused are solved, and the service level of rail transit is improved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit transportation, in particular to a method and system for determining the stop sequence of express and slow subway trains on suburban lines. Background technique [0002] With the continuous advancement of China's urbanization process, the passenger flow between the central city and the suburbs and satellite towns is increasing day by day. The tidal passenger flow characteristics of the suburban rail transit lines in the morning and evening are obvious, the passenger flow distribution is uneven in time and space, and it is mainly concentrated in some stations, and the passenger rate of trains in off-peak hours is low. Therefore, if the station stop plan is still implemented, the operating efficiency will be reduced, which will cause a certain waste of passenger travel time and enterprise transportation costs. Research on the stop plan of express and slow trains that matches the characte...

Problems solved by technology

Due to the large amount of data accumulated in the Oracle database, the complexity is high, and the rationality of the field design was not good when the database was built in the early stage, etc., resulting in redundancy or even errors in the stored data, and these data were not well utilized for the rail transit train operation plan Provide decision basis
