The Ann Arbor Area Transportation Authority (AAATA) is the public authority responsible for bus service in Ann Arbor and Ypsilanti. The downtown hub for the AAATA is the Blake Transit Center, which was rebuilt in 2013-2014.

Not to be confused with the Michigan Bus System.

Workers at AAATA are organized in the Transport Workers Union Local 171.

Real time information

The AATA provides real time information about bus locations and schedules for mobile phones on a service called Mobile RideTrak.

Future of Ypsilanti Service

The future of Ypsilanti bus service by the AATA is in doubt because of budget constraints. The current budget plan involves cutting AATA Route 3 and AATA Route 5 to Ypsilanti by 2007 and all routes by 2009. The organization Keep Ypsi Rollin has proposed a change to the Ypsilanti city charter that would continue service.

Update: June 21, 2013: The City of Ypsilanti has officially been added to theAATA board and the AATA has now become the AAATA  Ann Arbor Area Transportation Authority.
