Zusammenfassung

We introduce a framework to create a world-wide live map of public transit, i.e. the real-time movement of all buses, subways, trains and ferries. Our system is based on freely available General Transit Feed Specification (GTFS) timetable data and also features real-time delay information (where available). The main problem of such a live tracker is the enormous amount of data that has to be handled (millions of vehicle movements). We present a highly efficient back-end that accepts temporal and spatial boundaries and returns all relevant trajectories and vehicles in a format that allows for easy rendering by the client. The real-time movement visualization of complete transit networks allows to observe the current state of the system, to estimate the transit coverage of certain areas, to display delays in a neat manner, and to inform a mobile user about near-by vehicles. Our system can be accessed via http://tracker.geops.ch/. The current implementation features over 80 transit networks, including the complete Netherlands (with real-time delay data), and various metropolitan areas in the US, Europe, Australia and New Zealand. We continuously integrate new data. Especially for Europe and North America we expect to achieve almost full coverage soon.
