Roads and Highways

Improving, Expanding for Future Growth

Metro Atlanta sits at the intersection of three major interstate highways and serves as a major logistics hub for the Southeast and the nation.

The Atlanta Regional Commission, the transportation planning agency for the 20-county region, forecasts metro Atlanta’s population will reach 8.6 million by 2050. ARC and its partner agencies are working on a number of fronts to address this growth in order to reduce congestion and increase transportation options, while improving safety and air quality:

  • Regional Transportation Plan (RTP) – The region’s long-term transportation plan includes over $98 billion to maintain and improve roads and highways in metro Atlanta through 2050. Highlights of the RTP include a network of managed toll lanes on area highways and improvements to major interchanges and arterial roads
  • Transportation Improvement Program (TIP) – The TIP allocates federal funds for use in construction of the highest-priority transportation projects contained in the Regional Transportation Plan. The current TIP covers the first six years of the RTP. Projects in the TIP must be fully funded
  • Regional Freight Mobility Plan – ARC, working with a Freight Advisory Task Force, has developed a regional freight plan designed to improve the movement of goods throughout metro Atlanta.
  • Georgia Commute Options – This program encourages a range of alternative commuting options, such as carpooling, vanpooling, transit and teleworking.
  • Transportation System Management & Operations (TSM&O) – Overhead warning signs, efficiently timed traffic signals, traffic monitoring, and other technological advances help reduce congestion and improve safety.

Congestion Management Process

A congestion management process (CMP) is defined as a systematic approach for managing congestion by providing information on the performance of the roadway system and considering a variety of solutions that meet local needs.  While a CMP must be an integral part of a metropolitan planning process, federal regulations are not prescriptive regarding the methods and approaches which must be utilized. ARC incorporates the required elements of a CMP throughout all aspects of its modal and subarea planning activities, with the Regional Transportation Plan serving as the ultimate end product of the Atlanta region’s congestion management process.
