Using the Internet in a Mobile Public Transport Navigation System

In this demo, we present a Java ME application for mobile phones that supports people traveling in a city and relying on public transport. Our application is able to retrieve destinations and connections from various web services. In this way, it is an implementation of a ubiquitous Internet-based information retrieval system. In the current version, our system runs in the metropolitan region of Nuremberg, Germany, and maintains 2,200 bus, tram, train, and sub way stops along with all lines. The abstract sketches the system architecture and describes how the system uses information from the Internet.
