By conducting a comprehensive review of domestic and international research findings, this study examines the data collection and utilization of smart city rail transit systems. It identifies the essential functional modules necessary for the overall architecture of such systems. The study also elucidates the establishment of processes within the perception and data collection layer, the data processing and analysis layer, and the control and management layer. Furthermore, it investigates the interrelationships among system components and the internal flow of information. The establishment of smart city rail transit system architecture helps to sort out and coordinate all kinds of information and data of the rail transit system, improve the efficiency of information collection and conversion, enhance the overall smoothness and safety of rail transit, and promote the establishment of a complete urban rail transit travel service system.
