New York City possesses the most extensive and complex public transit system in North America, often regarded as "good" for its 24/7 availability and vast coverage, but criticized for its aging infrastructure. As of 2026, the Metropolitan Transportation Authority (MTA) has made significant strides in modernization, achieving its best on-time performance in years through the installation of new signal technology (CBTC) and the rollout of hundreds of new "R211" subway cars. The system is incomparable in its ability to move nearly 2 billion riders annually across subways, buses, and commuter rails. However, challenges remain, including ongoing accessibility gaps (only about 50% of stations are fully accessible) and the high cost of maintenance for its century-old tunnels. While New Yorkers frequently complain about delays and cleanliness, the city’s "transit-oriented" lifestyle remains the benchmark for urban mobility in the U.S., offering a level of connectivity that makes owning a personal vehicle unnecessary for the vast majority of residents and visitors.
