NextBus

NextBus is a vehicle tracking system for public transportation vehicles, especially buses and trams/light rail operations. Each vehicle is outfitted with a GPS receiver, which transmits data about bus or tram speed and location to produce projected arrival/departure times. These times are broadcasted to electronic signs at bus stops and tram stops and to the Internet including to wireless devices such as cell phones and PDAs. NextBus also provides management tools so that transit agencies can better manage their systems.
