Abstract

The invention discloses a method and a system for analyzing the outlet / inlet section line capacity of an urban railway system. The method comprises the following steps of: (S1) determining line data, train data and signal system data and dividing a line into a plurality of intervals; (S2) simulating various tracking conditions in the running of trains according to the data and recording the time of all trains of clearing timing points to obtain the running time of the trains between the timing points; (S3) calculating outlet section traveling intervals under different tracking conditions according to a simulating result, calculating a final outlet section traveling interval according to the outlet section traveling intervals to obtain the outlet / inlet section line capacity of the trains, the reserved capacity and a station stopping time maximum value; and comparing the obtained parameters with running requirements as well as analyzing, and outputting a final analysis result. The method and the system improve the scientificity, the comprehensiveness and the accuracy of analyzing the outlet / inlet section line capacity, realize the automation of the analysis process of the outlet / inlet section line capacity and save the labor force.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a method and system for analyzing the capacity of an entry and exit section of an urban rail transit. Background technique [0002] The depot entry and exit line belongs to the wiring of urban rail transit. It is the running line for trains to enter the main line from the depot or return to the depot from the main line. The requirement for the number of trains leaving the section within a specified time before the peak is coming to meet the traffic density of the main line during the peak hour; secondly, the requirement for the number of trains entering the section within the specified time before the end of the morning and evening peaks should be considered to increase the passenger capacity of the trains running on the main line. Outbound capacity is the capacity indicator of inbound and outbound lines, and inbound capacity is the economic indicator of inbound and ou...
