Xpress is a regional commuter coach service operated as a partnership between the Georgia Regional Transportation Authority (GRTA) and Clayton, Cherokee, Cobb, DeKalb, Douglas, Forsyth, Fulton, Gwinnett, Henry, Paulding, and Rockdale counties.
Operators of Xpress are contracted through Professional Transit Management and American Coach.
In Cobb and Gwinnett Counties Cobb Community Transit or Gwinnett County Transit provide Xpress service in addition to their own express services.
However, due to the popularity of its bus service (overcrowding on routes has become commonplace) the agency has already reached this goal.
A second expansion phase is now being implemented to have 47 routes in operation by the 2013 fiscal year.
