In North Carolina, this process is carried out by Metropolitan Planning Organizations (MPO). There are currently 17 urban areas in North Carolina, which participate in the 3-C transportation planning process.
They are:

• Asheville (French Broad River MPO)
• Burlington
• Cabarrus- Rowan
• Charlotte (Mecklenburg-Union) (MAMPO)
• Durham-Chapel Hill-Carrboro (DCHC)
• Fayetteville (FAMPO)
• Gastonia
• Goldsboro
• Greensboro
• Greenville
• Hickory-Newton-Conover
• High Point
• Jacksonville
• Raleigh (CAMPO)
• Rocky Mount
• Wilmington
• Winston-Salem

In North Carolina, MPOs typically are represented by two principal committees: the Technical Coordinating Committee and the Transportation Advisory Committee. A Lead Planning Agency is designated for each MPO and provides staff support for MPO functions

The Technical Coordinating Committee (TCC) is comprised of staff representatives of the various member local, state, and federal government agencies, transit providers, and other agencies with an interest in transportation planning. The TCC has the responsibility of making technical recommendations to the Transportation Advisory Committee on decisions pertaining to transportation planning including the 3C process, and the multi-modal Comprehensive Transportation Plan.

The Transportation Advisory Committee (TAC) is the governing policy board for the MPO. The TAC’s membership includes elected officials, members of local government, the area’s representative on the NC Board of Transportation, an advisory member from FHWA, and other members as may be designated. The TAC provides policy direction for the planning process, provides for public involvement, and guides the development of a comprehensive multi-modal transportation program for the urban area (both long range plans and funding programs).
