Near-Term Regional Transportation Improvements
The Transportation Improvement Program (TIP) allocates federal funds for use in the construction of the highest-priority projects in the Metropolitan Transportation Plan (MTP), the long-term transportation vision for the 20-county region. Projects included in the TIP must be fully funded.
The Atlanta Regional Commission, the federally designated Metropolitan Planning Organization for the 20-county Atlanta region, is responsible for developing and updating the TIP and MTP to meet federal planning requirements and address local needs.
The TIP covers the first four years of the MTP, and is the means by which federal, state and local funds are approved for all significant surface transportation projects and programs in the 20-county Atlanta region.

Metropolitan Transportation Plan
ARC’s Metropolitan Transportation Plan is a long-range document that maps out the transportation projects that will be most useful to the region through 2050. The MTP is the transportation component of the Atlanta Region’s Plan and is based on the amount of funding we think will be available during that time.
Title VI
ARC is committed to enforcing the provisions of Title VI of the Civil Rights Act of 1964 and taking positive and realistic affirmative steps to ensure the protection of rights and opportunities for all persons affected by its programs, services, and activities.
