What is the largest public transportation system in the United States?

The largest public transportation authority in the U.S. is the Metropolitan Transportation Authority (MTA), the corporation responsible for mass transit in the New York metropolitan area.



The New York City Metropolitan Transportation Authority (MTA) remains the largest public transportation system in the United States in 2026. It is a massive network that includes the NYC Subway, the Long Island Rail Road (LIRR), Metro-North Railroad, and an extensive bus fleet, serving over 15 million people across a 5,000-square-mile region. Interestingly, if you define "statewide" systems, NJ TRANSIT is the nation's largest single-state provider, operating hundreds of bus and rail lines across New Jersey. On a regional scale, systems like DART in North Texas are also major contenders for geographic coverage. However, in terms of sheer ridership and infrastructure (including over 470 subway stations), the MTA is the undisputed giant, moving more people daily than the next several largest U.S. transit systems combined.
