Welcome to the ATL Transit Developers Google Group!
This group is devoted to discussion of Atlanta transit data (both static GTFS and realtime) and the development of web and other software applications. Discussion is focused primarily on MARTA (
http://www.itsmarta.com/developers/default.aspx) which is currently, as of November 2012, the only open data source in the region.
Please use this forum to ask questions, post newsworthy items/events, or spark conversation relevant to the topic. Happy posting!
