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

Abstract

The invention is applicable to the technical field of rail traffic and provides a method for optimizing train stop stations of a rail traffic route. The method comprises the following steps: acquiringpassenger flow characteristics of a route to be optimized, and judging whether the route to be optimized meets conditions of rapid and slow trains or not according to the passenger flow characteristics; if the route to be optimized meets the conditions of rapid and slow trains, acquiring basic information of the route to be optimized; processing the basic information so as to obtain optimal matrixes with intervals of route stations, interval operation time division tables and one-direction traffic capacity data of optimized time sections; inputting the optimal matrixes into an optimizing model, solving a quasi-optimal solution of the optimizing model by using a genetic algorithm, acquiring a rapid train stop station scheme, and optimizing the rout to be optimized according to the rapid train stop station scheme. By adopting the method of the embodiment of the invention, the outgoing efficiency of passengers can be improved, an addition attraction function is achieved for passengers along a route, and under large and small cross route conditions, the transferring rate of train carriages is reduced, the train carriage use number of a route is reduced, and the operation cost is 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...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a train stop optimization method and system for a rail transit line, aiming to solve the problem that in the existing urban rail transit travel optimization scheme, only the total travel time of passengers is considered, and the fast and slow trains are not considered. The influence of time express bus stops, resulting in the problem that the optimal route is not perfect
