Data interface model for passenger-centric intermodal traffic management

Kurzfassung

Purpose: Meeting the needs of passengers will increasingly become a competitive factor for each stakeholder of the air transportation system. To achieve this goal, a passenger-centric view needs to be employed. Since passengers may encounter many modes of transportation during travel, adopting the passenger-centric view leads in a natural way to intermodality. Timely providing relevant information is one of the most demanded services. Exact knowledge of information and respective interfaces required may lower the inhibition threshold of stakeholders to share information. Methodology: In this paper we describe the data model and the interface model necessary to implement a Passenger Information System on a mobile device. The features of our system comprise real-time and personalized information about departure times of urban transport and air transport, estimated time to complete the next step, such as check-in or security check, and estimated spare time for visiting the retail area. Findings: Data model and interface model are described by using standard methods in computer science, so that the description is independent of the implementation itself. Furthermore, it is transferable to other situations where a Passenger Information System is to be installed, such as big events, urban emergency, or evacuation scenarios.
