The Greater Buffalo-Niagara Regional Transportation Council is the Metropolitan Planning Organization (MPO) for Erie and Niagara Counties. By federal law, an MPO is designated by each state's governor for every urban area in the United States of America with at least 50,000 residents. MPOs devise solutions to regional transportation problems, which involves addressing land use, air quality, energy, economic development, and commerce. The GBNRTC is focused on establishing a comprehensive, cooperative, and continuing transportation planning process for Erie and Niagara Counties' metropolitan area.
