Google Latittude was launched last week. It brings real time location updates of friends using Mobile phones. This features opens up a bunch of possibilities - one of which is in Indian Public Transport system.
Idea - Provide real time update on Indian Public Transport, using Google Latitude ( similar to London )
Resource : A compatible mobile phone in each public bus / train. Use of the Google Lattitude API ( not available right now, but can be requested ? ). One website, which updates the location info, which can be accessed from mobile / PC
Monestisation : This service for each bus / train might cost about 12k every year for connection plans + cost of device (12k ) + maintenance cost ( hosting / support - 12 lakh per year ? ).
The website will have ads. Also, people can also request location info with a simple SMS. So, ads can be sent through SMS, for every request. Ads bring in monies.
Benefits : More usage of public transport ( since i can plan my travel better )
