I was reading the GTFS specifications a few hours back and then I realized that in India, no transit authority publishes any such information.
Seeing the commonwealth games this year, I guess and hope that DMRC and DTC can publish transit information in GTFS format, so that the developers can come up with some web, mobile and iPhone applications. These applications will for sure make it much easier for everyone to commute and find the modes of transportation. The biggest benefit will be for the foreigners, who can use these apps to locate a metro station, get the schedule information, locate bus stops and get to know about timings and other gamut of information.
Most of the transit authorities in USA are using GTFS specs to publish information for the developers to come up with commuter friendly applications.Now is the time for DMRC and DTC.
