This vehicle tracking app combined with an AddTransit (https://addtransit.com) account allows you and your passengers to know where your transit vehicles are at all times.

Tracking your vehicles is easy. The AddTransit Vehicle Tracking app allows you to send your vehicle's GPS location to AddTransit. Your vehicles position can then be shown on your website or made available in the GTFS-Realtime format on online maps, journey planners & other transit apps.
