Under the integrated operation management of Intercity and Metro in the GuangdongHong KongMacao Greater Bay Area, the station functional layout′s standardized design is conducive to improving the quality of passenger services and the efficiency of operation management. The intercity and metro principles of integrated functional layout are summarized through differential analysis of typical metro and intercity stations based on restructuring the station′s functional space of public and equipment areas to achieve a comfortable, convenient, and efficient standardized station in the GuangdongHong KongMacao Greater Bay Area. Then, a new functional space combination of three spaces (security control, comprehensive service, and traffic distribution spaces) in the public area and three zones (office and living, intelligent system, and electromechanical equipment areas) in the public area of the Greater Bay Area station is proposed. Finally, the optimization ideas of public areas (security check and observation area, selfservice, ticket facilities, transportation facilities, humanized facilities, and column network standards) and equipment areas (room function configuration and room module layout) are discussed, obtaining the station′s standardized design scheme. The results can provide a reference for a new round of linenetwork station standardization designs.
