The objective of this project was to create a real-time, context-aware transit navigation system. The system integrates the route-planning and real-time tracking functionality provided by current systems into a single, real- time and context-aware application, combining a smartphone end-user device with a sophisticated back-end service. The completed navigation system supports unified real-time transit navigation, including walking, biking or handicapped access, across all three Chicago transit agencies: CTA buses and subway trains, Pace suburban buses, and Metra commuter rail. The back-end is built as a generic routing service, which can be used by any number of client applications. On the client side, an application has been created and made available for public download, with an attractive user interface and a wide selection of convenient features.
