Urban rail transit multi-interlaced-line transportation organization optimization method based on ticket business information

Abstract

The invention discloses an urban rail transit multi-interlaced-line transportation organization optimization method based on ticket service information. The urban rail transit multi-interlaced-line transportation organization optimization method comprises the following steps: carrying out the extraction of basic data and the processing of passenger travel time records based on the ticket service information in a workday peak period; generating an effective path set between a starting point station and a terminal point station of passenger travel, and estimating path travel time; establishing aGaussian mixture model for describing multi-interlaced-line travel time distribution and designing a solving algorithm, and solving model parameters; solving section passenger flow volume, and generating a travel passenger flow statistical table; judging whether the passenger flow condition of the line is suitable for a multi-interlaced-line train running scheme or not; establishing a multi-interlaced-line train operation optimization model on a line suitable for the multi-interlaced-line train operation scheme; and solving the multi-interlaced-line train operation optimization model to obtain a multi-interlaced-line train operation optimization scheme. The urban rail transit multi-interlaced-line transportation organization optimization method is high in applicability and easy to implement, improves the operation efficiency, and saves the operation cost.

Description

technical field [0001] The invention belongs to the field of rail transit, and in particular relates to an optimization method for multi-way transportation organization of urban rail transit based on ticketing information. Background technique [0002] The urban rail transit system is generally composed of a network composed of multiple interweaving lines. Usually, the trains of each line run independently without crossing the line. Therefore, for the decision makers of the transportation organization, the train operation plan is mainly formulated according to the passenger flow of a single line. For this reason, the present invention innovatively proposes a quantitative calculation method, thereby obtaining a multi-crossing train running plan that is more in line with the passenger flow distribution characteristics. [0003] The characteristics of single-line passenger flow distribution are the basis for formulating train operation plans. However, urban rail transit system...
