Regional Planning Approach

The National Capital Region Transportation Planning Board (TPB) is the federally designated Metropolitan Planning Organization (MPO) for the region, and plays an important role as the regional forum for transportation planning. The TPB prepares plans and programs that the federal government must approve in order for federal-aid transportation funds to flow to the Washington region.

The TPB's planning activities must follow regulations and meet standards set forth in federal law. The TPB works with more than 20 local jurisdictions, two states and the District of Columbia, and multiple transportation agencies to develop a policy framework that will guide transportation decision making in the National Capital Region for decades to come.
