Björn Greßmann, Helge Klimek and Volker Turau. Intelligent Passenger Flows in Airport Terminals Using a Digital Boarding Assistance. In Proceedings of the 8th International Workshop on Intelligent Transportation (WIT2011), March 2011. Hamburg, Germany.

Abstract: In this paper we present a Digital Boarding Assistance (DigiBa) system for passengers in airport terminals. By providing navigation, notification and information services, passengers are enabled to move efficiently through the terminal. Based on functional requirements of such a system, the paper presents a prototype implementation on an embedded mobile device with restricted resources. Challenges concerning channel access in dense networks and indoor navigation on a device with limited hardware capabilities are outlined.

Abstract: This report describes usage scenarios of the architecture for indoor navigation and location based services (INLBS) developed in the Airport2030 project. The expandable architecture offers a framework and predefined services with a runtime environment and aims at enabling ubiquitous INLBS in any building with the users’ mobile device. The architecture consists of a mobile user platform (MUP) installed on mobile devices and a stationary facility platform (SFP) which is running on backend servers. For communication between MUP and SFP a communication and positioning infrastructure (CPI) is used. The SFP abstracts from different mobile hardware and communication and ranging technologies for ease of development. A runtime environment contains the service container which invokes life cycle functionality of the different services. Applications which are accessed from the MUP are developed using the services in the service container.

Abstract: Outdoor navigation services have become ubiquitously available due to small handheld devices such as GPS enabled mobile phones or dedicated mobile navigation systems. Two main drivers were necessary in order to provide widespread location based services: Acquiring positioning information with a certain degree of precision and widespread (mobile) access to computer networks to use the position information with a large information basis such as the Internet. Envisioned is a future, where indoor navigation and location based services are used as naturally as outdoor location based services are now. To achieve this long term vision where users seamlessly navigate for example from work desk to departure gate at the airport and use location based services on the way, various challenges have to be solved. In this paper, these challenges and open issues are discussed. The paper proposes an architecture which abstracts from different mobile devices and localization technologies. Additionally, it sketches the use of indoor topology information to increase the accuracy of indoor localization. These two presented concepts form a basis for a transition period until standards for ubiquitous indoor location based services have emerged.
