The Metropolitan Atlanta Rapid Transit Authority (MARTA /ˈmɑːrtə/) is the principal public transport operator in the Atlanta metropolitan area. Formed in 1971 as strictly a bus system, MARTA operates a network of bus routes linked to a rapid transit system consisting of 48 miles (77 km) of rail track with 38 subway stations. MARTA's rapid transit system is the eighth-largest rapid transit system in the United States by ridership.
MARTA operates almost exclusively in Fulton, Clayton, and DeKalb counties, although they maintain bus service to two destinations in neighboring Cobb County (Six Flags Over Georgia and the Cumberland Transfer Center next to the Cumberland Mall which offers a connection to many CobbLinc bus services), while Doraville station serves portions of Gwinnett County via Ride Gwinnett buses. MARTA also operates MARTA Mobility, a separate paratransit service for disabled customers MARTA Reach, an on-demand microtransit service for people in areas with first or last-mile issues within their neighborhood.
In 2025, the entire system (bus and subway lines) had 65,752,400 rides, or about 179,500 per weekday in the fourth quarter of 2025.
After 2000, expansion of the MARTA system stalled, after the completion of three new rail stations north of the Interstate 285. In 2016, Atlanta voters approved a historic sales tax increase to raise $2.7 billion over 40 years, in order to significantly expand the MARTA system (dubbed the More MARTA program), including 29 miles of light rail transit, 13 miles of bus rapid transit, arterial rapid transit, transit centers and multiple infill MARTA stations. Since its inception, the More MARTA program has been criticized for slow progress, delays, and reversals on executing its list of expansion projects.
