With the constant increase in smartphone sales, integrated sensors and map navigation have now become available to the average user. This allows for mobile applications to use context-awareness to provide more relevant information. An interesting use-case for such applications is a route information system for buses. The paper describes an application which interfaces over a mobile phone to Bus-TUC, a natural language-based reasoning-system for bus routes in Trondheim. By combining user context, BusTUC reasoning and real-time data from the bus service provider, the user-interaction is simplified, compared to a standard information system. We discuss issues on supporting context-awareness and real-time information in this system, comparing it to other available route information systems. Feedback from beta-testers indicates that the application suits the needs of typical bus travelers well.
