Abstract: In response to the situation where railway passengers were unable to accurately obtain comprehensive transportation information for the next stage of their journey during transfer, this paper designed a railway passenger integrated transfer service information system, introduced the overall architecture and key technologies of the system, and implemented functions such as data interface management, data processing, system management, and information display for railway passenger integrated transfer. The system can not only facilitate passenger transfer, but also alleviate the work pressure of railway passenger station personnel, reduce labor costs, and improve work efficiency.
