Abstract: To meet passengers’ transfer guidance demands under the Mobility as a Service (MaaS) framework, this paper proposed a passenger information service scheme for urban rail transit based on MaaS. Centered on passengers’ information requirements throughout all travel stages, the scheme integrated passenger service resources via multi-source data fusion and supported collaborative perception and intelligent analysis of multi-disciplinary data. By adopting integrated information broadcasting management and service deduction technologies, the scheme delivered online and offline travel information services, realized dynamic passenger diversion and service strategy optimization, and overcame the constraints of homogenized supply and passive response in traditional passenger information services. Application results show that the scheme enables integrated access to urban rail transit and bus information alongside dynamic multi-terminal information distribution, and significantly improves the accuracy of passenger transfer guidance and the intelligence level of travel services.
