A Context Aware Transit Navigator

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, such as the Apple iPhone, 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 iPhone application has been created, with an attractive user interface and a wide selection of convenient features. The iPhone application has been published on the iTunes App store for public download. The app is downloaded by approximately 2,000-3,000 users per month, and has received over 1,000 reviews, many of which are very positive.
