Abstract

The invention discloses a rapid method for solving the connection problem of urban rail transit last trains. The method includes the following steps that S1 based on field research and data collection of large and medium-sized cities at home and abroad, a decision support underlying database of an urban rail transit system is established; S2 a space-state network is established by adopting the idea of network flow modeling and taking the branch direction line as the vertex and the connection relation as the edge, and the weighted directed graph model of the last train connection plan is constructed by taking the transfer passenger flow as the weight of the edge; S3 the weighted directed graph model is solved by an improved Zhu-Liu method; S4 an optimized line connection plan is obtained based on the solution result; and S5 based on the optimized connection plan, the arrival and departure time of other lines to each station can be calculated. Aiming at solving the problem of the last train operation plan of a large-scale public transportation network, the method can conveniently and rapidly make a real-time last train time table based on passenger flow demands, thereby improving the reachability and service level of the urban rail transit last trains.

Description

technical field [0001] The invention relates to the field of urban rail traffic control. More specifically, it relates to a fast method for solving the connection problem of the last train in urban rail transit. Background technique [0002] From a global perspective, urban rail transit has become an indispensable mode of urban transportation. The rail transit systems in major cities in my country are also improving day by day, and are gradually transitioning to networked operations. After the urban rail transit network is put into operation, the issue of train operation plan preparation becomes complex and changeable. Coordinating transfer connections within the entire transportation network is the key to dealing with network operation issues. Among them, the operation plan of the last train is the most typical among all kinds of transfer connections. To solve such problems, not only the characteristics of networked operation and passenger flow demand characteristics, but ...
