Starting from the perspectives of multiple subsystems, including people, stations, and trains, and combining passenger flow, system structure, and multiple attributes of trains, a system dynamics (SD) model for passenger travel in airport hub subway stations is established. The model is simulated using Vensim PLE 5.9d to analyze the effective carrying capacity of the transfer system under the existing configuration and layout of transfer facilities and equipment in the hub. The model features a modular architecture and interface, enabling quick and easy model establishment, and adapts to various configurations and operational characteristics of airport hub subway stations in a user-friendly manner. Multiple sensitivity simulation analysis experiments are designed to analyze changes in passenger flow density from multiple perspectives. This method can calculate the effective carrying capacity of airport hub subway stations, providing a scientific basis for planning, construction, and operational management. The effectiveness of the model is verified by analyzing the Pudong International Airport terminal subway station.<\/jats:p>","DOI":"10.3390\/systems13020133","type":"journal-article","created":{"date-parts":[[2025,2,18]],"date-time":"2025-02-18T09:45:23Z","timestamp":1739871923000},"page":"133","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Passenger Flow Simulation of Airport Terminal Subway Station Based on System Dynamics"],"prefix":"10.3390","volume":"13","author":[{"given":"Wei","family":"Chen","sequence":"first","affiliation":[{"name":"College of Air Traffic Management, Civil Aviation Flight University of China, Guanghan 618307, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Ai","sequence":"additional","affiliation":[{"name":"College of Air Traffic Management, Civil Aviation Flight University of China, Guanghan 618307, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"593","DOI":"10.1016\/j.buildenv.2015.10.014","article-title":"Investigation of indoor environment quality of Chinese large-hub airport terminal buildings through longitudinal field measurement and subjective survey","volume":"94","author":"Wang","year":"2015","journal-title":"Build.
