Transloc - Transit Visualization System
Transloc TVS have produced a large number of real-time Google Maps showing the locations of buses on a large number of US university transit systems.
Using a Transloc map students can view in real-time the position of buses on a campus map. The maps show the buses in real-time actually moving on the map. Each map also includes the bus routes and the position of stops on that route.
Using the map sidebar you can select to view any route or any combination of routes on the map. Transloc is also available as an iPhone application.
