Answer:
The transportation system of New York City is a network of complex infrastructural systems. New York City, being the most populous city in the United States, has a transportation system which includes one of the largest subway systems in the world; the world's first mechanically ventilated vehicular tunnel; and an aerial tramway. New York City is also home to an extensive bus system in each of the five boroughs; citywide and Staten Island ferry systems; and numerous yellow taxis and boro taxis throughout the city. Private cars are less used compared to other cities in the rest of the United States.
Within the New York City metropolitan area, the airport system—which includes John F. Kennedy International Airport, LaGuardia Airport, Newark Liberty International Airport (located in New Jersey), Stewart Airport and a few smaller facilities—is one of the largest in the world. The Port of New York and New Jersey, which includes the waterways around New York City and its metropolitan area, is one of the busiest seaports in the United States. There are also three commuter rail systems, the PATH rapid transit system to New Jersey, and various ferries between Manhattan and New Jersey. Numerous separate bus systems also operate to Westchester County, Nassau County, and New Jersey. For private vehicles, a system of expressways and parkways connects New York City with its suburbs.
