Regional Transportation Planning

The National Capital Region Transportation Planning Board—the TPB for short—coordinates transportation decision making for D.C., Suburban Maryland and Northern Virginia.  The TPB’s members include local officials—mayors, city council members, county board members and others—as well as representatives from the state transportation agencies, the Washington Metropolitan Area Transit Authority and the state legislatures. The TPB is staffed by the Metropolitan Washington Council of Governments.

The TPB is designated as a Metropolitan Planning Organization (MPO) under federal law, which prescribes key aspects of the regional transportation planning process in every metropolitan region across the country.  There are nearly 400 MPOs in the U.S.
