Bangalore Live Bus Tracking
This site is tracking buses of the Bangalore Metropolitan Transport Corporation live on a Google Map. The buses all carry GPS units so the map is able to update locations once a minute.
It is possible to track all BMTC buses at once or select an individual bus to track. If you click on a bus map marker you can get the route information and speed of the bus. There is also a mobile phone version of this map, so it is possible to work how long you will have to wait for a bus when you are out and about in Bangalore.
This map comes from the same developer as the Indian Train Tracker.
