A method and system for optimizing train stops on a rail transit line

Abstract

The present invention is applicable to the technical field of rail transit and provides a train stop optimization method for rail transit lines, which includes: obtaining the passenger flow characteristics of the line to be optimized, and judging whether the line to be optimized satisfies the conditions for running fast and slow trains based on the passenger flow characteristics; If satisfied, collect the basic information of the line to be optimized; process the basic information to obtain an optimization matrix including line station spacing, interval operation time table and one-way traffic volume data during the optimization period; input the optimization matrix In the optimization model, a genetic algorithm is used to solve the approximate optimal solution of the optimization model to obtain an express train stopping plan, and the express train stopping plan is used to optimize the line to be optimized. Through the embodiments of the present invention, the travel efficiency of passengers can be improved, and the passenger flow along the line can be induced. Under large and small traffic conditions, the turnover rate of the vehicle bottom can be shortened, the number of vehicle bottoms used on the line can be reduced, and the operating cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a train stop optimization method and system for a rail transit line. Background technique [0002] With the continuous expansion of city scale, my country's urbanization process has been significantly accelerated, and urban rail transit has also extended to satellite towns, resulting in urban rail transit lines. Urban rail transit lines mainly serve the commuting traffic between the central city and the suburbs. They have the characteristics of long distances, many stations, and uneven distribution of passenger flow in time and space. It plays an important role in optimizing the overall network of urban rail transit. [0003] The research on the stop scheme of fast and slow trains is one of the key contents of the research on the operation scheme of urban rail transit. It can effectively improve the operational efficiency of the urban rail transit system, shorte...
