Abstract: Objective: In the current design specifications, the overall scale of urban rail transit stations is judged by platform width scale. However, due to the complexity of surrounding environment, this indicator no longer reflects the actual conditions of station overall scale. Therefore, it is necessary to carry out analysis of urban rail transit station construction scale influencing factors.Method: A data analysis model for station scale is established. Station scale influencing factors such as station area proportion composition, train type, auxiliary line setting, and station buried depth are selected for the analysis, and the impact proportions of two among these factors are calculated.Result & Conclusion: In Guangzhou, the proportion of public areas on the concourse level of a 6A (6car formation, Atype vehicle) step down standard station is approximately 30%, while the proportion of equipment management rooms accounts for 70%. Among the equipment management rooms, the proportion of environmental control equipment rooms and ducts is relatively high, accounting for about 50% of the concourse level equipment management rooms. The area proportion composition conditions in standard reference diagrams for Guangzhou Metro 6A and 6B (6car formation, Btype vehicle) stations is similar, and the impact of different train types on the overall station scale takes up only 7%. The auxiliary line setting has a significant impact on station construction scale, and attention should be paid to the system functionality of auxiliary lines at the initial design phase, with a reasonable selection of auxiliary line schemes. Under the same conditions of system functionality and service functions, stations with greater buried depth have a larger overall construction scale, with the factor of different buried depths accounting for 23% impact on the overall station scale.
