Description

Technical Field

[0001] This invention belongs to the field of transportation technology, and more specifically, relates to a method for the layout and facility configuration of public areas based on station passenger volume. Background Technology

[0002] In recent years, subway development has been dominated by an extensive development model, which focuses on scale expansion rather than efficiency improvement. This model can rapidly expand the coverage of the subway network and increase transport capacity. However, with the rapid expansion of urban rail transit networks, the construction and operating costs of subways, as an important part of urban public transportation, are also increasing year by year.

[0003] Based on the economic benefit analysis of subway lines, the original extensive development model is no longer suitable for the construction needs of modern subway stations. Cost control throughout the station's life cycle and refined design control will be the future direction of station construction. Currently, there is no in-depth research, both domestically and internationally, on controlling station investment through refined design during the subway construction period. Standard subway stations uniformly use a platform width of 11m or 12m, and the standards for public area service facilities on platforms of the same width are also identical. This setup leads to high redundancy in equipment terminal configuration, far exceeding passenger needs. Furthermore, the calculation methods for the same equipment vary across regions, and the setting principles do not consider the interoperability between facilities. This results in a mismatch between station size, entrance and exit gates, security screening machines, escalators, etc., and passenger flow, leading to a high vacancy rate for public area service facilities. This not only increases engineering investment during the station construction period but also raises management and maintenance costs during the operation period. Summary of the Invention

[0004] To address the issues of high vacancy rates of public area service facilities and high station operation and management costs in existing subway stations, this invention provides a method for public area layout and facility configuration based on station passenger volume. The method classifies stations according to peak hour passenger volume and determines the overall layout of the public area for different station levels, including column span dimensions and layout, achieving refined design of the public area layout. Furthermore, it links the adjustment of facilities such as entrance and exit gates, security screening equipment, and escalator / staircase cameras with the public area layout and the number of escalator / staircase groups, thereby reducing the vacancy rate of public area facilities and lowering station engineering investment and management and maintenance costs during operation.
