The Transportation Planning Board or TPB is a federally designated Metropolitan Planning Organization charged with developing a fiscally constrained long range transportation plan and six year transportation improvement program for the region. Members of the TPB include representatives of local governments, state transportation agencies, state and D.C. legislatures, and the Washington Metropolitan Area Transit Authority (WMATA), which runs the Metro System.
