As the Metropolitan Planning Organization (MPO) for New York City, Long Island and the lower Hudson Valley, NYMTC provides a collaborative planning forum to address transportation-related issues, develop regional plans and make decisions on the use of federal transportation funds for its planning area. To be eligible for these funds, NYMTC undertakes a transportation planning process specified in federal regulations. NYMTC is comprised of nine voting members and seven advisory members who develop plans, goals and a shared vision for the region's transportation network.
The NYMTC planning area covers 2,440 square miles and includes a population of 12.4 million, which was approximately 64% of New York State's population, based on the 2010 Census.
