Atlanta's transportation system is a complex multimodal system serving the city of Atlanta, Georgia, widely recognized as a key regional and global hub for passenger and freight transportation. The system facilitates inter- and intra-city travel, and includes the world's busiest airport, several major freight railclassification yards, a comprehensive network of freeways,heavy rail,light rail, local buses, andmulti-use trails.
Atlantabegan as a railroad town, and transportation remains an important part of its economy. Several major transportation and logistics firms are headquartered in Atlanta, includingDelta Air Lines, Norfolk Southern Railroad, andUnited Parcel Service.
Public transit, including theeighth-busiest rapid transit system in the United States, is operated primarily by theMetropolitan Atlanta Rapid Transit Authority (MARTA). The transit network also includes light rail and local bus routes. Despite these services, most Atlanta commuters chose to commute by car, with only 4.5% choosing to use transit in 2022.[1] Emphasis on cars has resulted in heavy traffic and has led to significant pollution and congestion. Limited efforts are underway to reduce Atlanta's dependence on cars in order to improve system performance and reduce its impact onclimate change, but several automobile capacity increases are also in the works.
In 1836, the state of Georgia decided to build a railroad to the Midwest and chose as the terminus a location that is nowDowntown Atlanta. Between 1845 and 1854, rail lines arrived from four different directions and Atlanta quickly became a commercial center and transportation hub for thesouth. In 1871,horsecars began operation in the city, and Electric Streetcars arrived in 1889.[2] by 1926, passenger service peaked at 96,794,273 people per year.The introduction of trolleybuses in 1937 led to the gradual decline and eventual end of electric streetcar service in 1949. At its height, the trolleybus system carried 80% of all transit riders.[3] By the end of 1949 Atlanta had 453 trolleybuses, the largest fleet in the United States,[3][4] butGeorgia Power had been losing money on the system since the 1920s. During the five-week-longtransit strike of 1950 the company began looking for buyers. Four local businessmen formed theAtlanta Transit Company (ATC) and purchased the transportation properties on June 23, 1950.
In late 1962 ATC operated 273 trolleybuses on 39 routes, but they decided to phase them out to avoid the expense and difficulty of replacing the extensive fleet and stringing overhead wires in new service areas.[5][6] The entire system was converted to diesel buses over a period of less than one month in September 1963.[5][7] ATC continued operating bus services until it was bought by the newly-formedMetro Atlanta Rapid Transit Authority (MARTA) in 1971.[8]
Meanwhile, national trends towardsfreeway expansion were taking hold in Atlanta. In the 1950s and 1960s, several new freeways, includingI-20 and thedowntown connector, were introduced. These freeways cut directly through many established communities, often intentionally targeting black neighborhoods likeSweet Auburn.[9] Like otherurban renewal projects, these decisions reinforced a pattern ofdisplacement and disinvestment in minority communities, and further entrenched de factosegregation in Atlanta that can still be seen today.[10]
State transportation planners continued to undertake frequent freeway expansion projects in the following decades. These included the completion of new interstates like theI-285 loop in 1969,I-575 in 1985,I-675 in 1987; theFreeing the Freeways interstate widening program, which doubled Atlanta's freeway lane miles between 1976 and 1988; and the introduction of HOV lanes in 1997.[11] Additional in-town freeway routes were proposed in the early 1960s but cancelled aftersignificant public backlash lasting over 30 years. While these projects were widely viewed at the time as necessary and impressive feats of engineering, modern transportation advocates feel that this overemphasis on car infrastructure has contributed to air and noise pollution,urban sprawl, and congestion.
Today, Atlanta commuters primarily choose to travel by car. 2022 census estimates show that, of workers commuting within the city, about 68% drove alone, 8% carpooled, and 5% used public transportation.[1] Atlanta has a reputation for bad traffic and has been ranked among the worst cities for commuters.[12] For this reason, some planners and activists have advocated for improved alternatives to driving. Organizations likePropel ATL are calling for better pedestrian and cycling infrastructure and improved transit performance. Projects like theBeltLine are intended to increase access to viable alternatives to driving. In April 2020, the Atlanta Department of Transportation (ATLDOT) committed to developing aVision Zero action plan to reduce traffic fatalities.[13]
Mostpublic transport in Atlanta is operated by theMetropolitan Atlanta Rapid Transit Authority (MARTA). MARTA's system is composed of heavy rail, light rail, and local bus systems. MARTA operates primarily within the boundaries of Fulton, DeKalb, and Clayton counties.
MARTA's heavy rail system operates on 47.6 miles (76.6 km) of elevated, ground-level, and underground tracks. Trains serve 38 stations located on four service lines: theRed Line,Gold Line,Blue Line, and theGreen Line.[14][15] All four lines meet at theFive Points station, located in downtown Atlanta.[15] MARTA trains are operated using theAutomatic Train Control system, with one human train operator per train present to make announcements, operate the doors, and to operate the trains manually in case of a control system malfunction or an emergency. Many of the suburban stations have free daily and paid long-termpark and ride lots, as well askiss and ride passenger drop-off areas.[15]
MARTA's bus system serves a wider area than the rail system, including areas in North Fulton, South DeKalb, and Clayton County. As of 2017, MARTA has 550 diesel andcompressed natural gas buses that cover over 101 bus routes.[14] While Cobb County is not part of the system, MARTA operates two bus routes there, one serving Cumberland Boulevard Transfer Center,[16] and the other servingSix Flags Over Georgia. All bus lines stop at at least one heavy rail station.
In addition to the free parking adjacent to many rail stations, MARTA also operates fivePark and Ride lots serviced only by bus routes: Windward Parkway, Mansell Road, Goldsmith, Barge Road, South Fulton, and Riverdale. The Panola Road Park and Ride lot is jointly operated withGRTA.
In May 2016, MARTA completed its Comprehensive Operations Analysis, which outlined a series of changes to its service across the system, but primarily focused on changes to the bus network. The analysis proposed a series of frequency changes, realignments, and additional service levels.[17] Starting in 2017, MARTA began implementing these changes. These changes will come both during MARTA's normal scheduled route modification dates, as well as on additional dates as part of the agency's "Fast Track" program.
TheAtlanta Streetcar system opened at the end of 2014 and has been operated by MARTA since July 2018.[18] The streetcar is a 2.7 mile loop that operates primarily in mixed traffic in the downtown area. It runs fromCentennial Olympic Park along Edgewood and Auburn avenues to theKing Center and has a stop at MARTA'sPeachtree Center Station.
Several other localities in the Metro Area operate local bus services. Of these,Cobb Linc andRide Gwinnett used to also offer commuter bus service connecting their local services with Atlanta. Until June 16, 2025, when those commuter services were incorporated introXpress, along with a series of service cuts to due budget constraints and low ridership. The Atlanta-region Transit Link Authority, a state-level entity, oversees theXpress bus system. Xpress operates 27 regional commuter bus routes connecting outlying cities and towns to Downtown and Midtown Atlanta.[19]Emory University operatesThe Cliff shuttle bus system with over 50 buses, 21 routes, and 200,000 rides per month.The Georgia Institute of Technology operates the Stinger Shuttles, providing service around its campus, theMidtown MARTA station, and neighboring communities.
Intercity bus services are operated byMegabus andGreyhound Lines, departing from outside theGarnett MARTA station downtown.
At theAtlanta Peachtree Station,Amtrak offers daily intercity train service on itsCrescent route betweenNew Orleans andNew York City.[20]
Most Atlantans rely on cars as their primary mode of transportation within the city. As of 2022, as little as 4.5% of commuters chose to use transit to get to work, and 85% of households had access to at least one car.[1][21] Atlanta is well known for its traffic; in 2023 it was found to have 3 of the top 15 biggest trucking bottlenecks in the country (a fourth was located in nearby McDonough),[22] and to be one of the worst for car commuters.[12]
Three majorInterstate highways converge in Atlanta:I-20 (east–west),I-75 (northwest–southeast), andI-85 (northeast–southwest). Parts of I-75 and I-85 runconcurrently for 7.4 miles through the center of downtown and midtown to form theDowntown Connector. This thoroughfare carries as many as 400,000 cars per day.[23] Atlanta is mostly encircled byInterstate 285, abeltway locally known as the Perimeter, which is commonly used to informally mark the boundary between the city and close-in suburbs ("inside the Perimeter" or "ITP") and the outer suburbs and exurbs: ("outside The Perimeter" or "OTP").Georgia State Route 400 diverges from I-85 nearBuckhead and travels north, crossing I-285 just north of city limits. The outer metro also has three otherauxiliary Interstates:I-575,675, andI-985. Interstates and state highways are administered and maintained by theGeorgia Department of Transportation (GDOT).
Peach Pass toll lanes have been introduced as part of the GDOT's Major Mobility Improvement Program (MMIP).[24] The first lanes, opened in 2011 on I-85 in Gwinnett County, were converted from existing HOV (High Occupancy Vehicle) lanes to HOT (High Occupancy Toll) lanes.[25] The second, on I-75 in Henry and Clayton Counties, opened in 2017 as the first fully barrier-separated section.[26] The third, known as the Northwest Corridor, opened in September 2018 on I-75 and I-575 in Cobb and Cherokee Counties.[27] Both of the I-75 facilities are reversible, meaning that the lanes flow towards downtown Atlanta in the morning, and toward the suburbs in the afternoon.
Cycling is a growing mode of transportation in Atlanta, taking 1.1% of all commutes in 2009, up from 0.3% in 2000,[28] and organizations likePropel ATL continue to lobby for increased accessibility to bicyclists.[29] However, heavy automobile traffic, Atlanta's famed hills, the lack of bike lanes on many streets, and difficulty in crossing major streets deter many residents from cycling frequently in Atlanta.[30] The city's transportation plan calls for the construction of 226 miles (364 km) of bike lanes by 2020.[31] TheBeltLine which will include multi-use, paved trails, may help the city achieve this goal.[citation needed]
Additional multi-use trails currently being developed throughout Atlanta include thePATH400 and thePeachtree Creek Greenway.
Starting in June 2016, Atlanta received a bike sharing program, known asRelay Bike Share, with 100 bikes in Downtown and Midtown, which expanded to 500 bikes at 65 stations as of April 2017.[32][33]
Situated10 miles (16 km) south of downtown,Hartsfield-Jackson Atlanta International Airport (IATA:ATL,ICAO:KATL) is theworld's busiest airport.[34] Hartsfield-Jackson offers air service to over 150 U.S. destinations and more than 70 international destinations in 43 countries, with over 2,100 arrivals and departures daily.[35]Delta Air Lines is headquartered nearby, and maintains its largest hub at Hartsfield-Jackson.[36] The domestic terminal hasits own MARTA heavy Rail station, and both terminals are easily accessible fromInterstate 75,Interstate 85, andInterstate 285.
Hartsfield-Jackson is the only airport in metro Atlanta with significant scheduled commercial air service. Other airports near Atlanta includeFulton County Airport (IATA:FTY,ICAO:KFTY) andDeKalb-Peachtree Airport (IATA:PDK,ICAO:KPDK), which primarily handlegeneral aviation.

In July 2012, there was a referendum on a 1-cent sales tax (SPLOST) to fund traffic and road improvements. the tax would have funded several streetcar routes along portions of theBeltline trail and connections onto MARTA stations and with the Downtown Loop streetcar. However, the vote failed by a wide margin.[37]
TheClifton Corridor is a proposed light rail line which would run fromLindbergh Center eastwards, following the existingCSX rail corridor toEmory University, continuing along the northern edge of Decatur via Suburban Plaza on N. Decatur Rd. and on to theAvondale MARTA station.[38] Funding is also dependent on the same eight-billion-dollar grant currently proposed.
There are currently two proposals for railway extensions to the network. The first proposed project involves heavy rail, the current mode used by Marta.[39] The Red Line will be extended from its current terminus at North Springs towards Alpharetta. It would cross over metropolitan route 400 twice. Stops are proposed at Northridge, Holcomb Bridge, Mansell, North Point Mall, Old Milton, and Windward Parkway. Funding is also depending on an $8 billion grant. The second proposal is for commuter rail, a form of rail, though long proposed, currently doesn't operate with Marta. The line extending to Clayton County[40] The line will have stations at East Point (connections to Red and Gold rapid rail lines), Mountainview ( for int. Terminal F) Forest Park, Fort Gillem, Clayton State, Morrow, Southlake and Jonesboro with Justice Center and Lovejoy a later phase. The line is being pitched as commuter rail though what type (EMU, DMU, etc.) is unknown. Agreements are being worked on with Norfolk Southern who owns the track. Rather than a proposed grant, this project would be half government funded, half taxpayer.
