System for improving line transportation capacity through third line

Abstract

The invention discloses a system for improving the line transportation capacity through a third line, and relates to the technical field of urban rail transit. A large station train operation line is arranged between the two station stop train operation lines, and the large station train operation line adopts a single-line two-way operation mode. According to the invention, a mode of a third line of rail transit is introduced, and the line turn-back capability in a three-line mode is tested through analogue simulation software Xdrive. Two-way requirements for passage transportation speediness and large transportation capacity are met through a third line, and a third line mode is adopted for improving and optimizing the transportation capacity. In the optimization mode, a three-wire scheme is adopted, the running proportion of fast and slow vehicles is large and can reach 1: 1, the running requirements of different passengers can be greatly met, the running number of the fast and slow vehicles can be dynamically adjusted at any time, and running is more flexible; branching operation of fast and slow vehicles does not influence each other, the operation time is more stable, and the operation plan is more accurate.

Description

technical field [0001] The disclosure of the invention relates to the technical field of urban rail transit, and in particular to a system for improving line transportation capacity through a third line. Background technique [0002] At present, the capacity of the urban rail transit system is closely related to the scale of urban rail transit construction and related technical conditions. Without major technological breakthroughs, once the construction of urban rail transit is completed, the system capacity will be determined accordingly. The transportation capacity of the traditional urban rail transit system is affected by the number of main lines, signal system, wiring form, number of assigned vehicles, and operation mode. In super-large cities, there are vast resources of medical care, education, employment, and life, attracting a large number of immigrants to settle and live here; prompting the continuous expansion of large cities, urban functions are gradually divided...

Problems solved by technology

[0034] (1) The capacity of the existing urban rail transit system cannot meet the needs of actual development

[0035] (2) There are operational waste and high operating costs in rail transit, and the utilization rate of transport capacity is low

[0042] The third line scheme is only suitable for lines (rays) with very obvious tidal passenger flow; it is not suitable for lines with rel
