Google Maps have added comprehensive transit data for the entire New York metro region, encompassing subway, commuter rail, bus and ferry services from the Metropolitan Transit Agency (MTA), the Port Authority of New York and New Jersey, New Jersey Transit and the City of New York.

This lead us to the fundamental goal of the Google Transit project: make public transit information as easy to find as any other geographic information. Google Transit now cover more than 170 cities and countries across the globe, including about 70 cities in North America and 81 in China, plus cities in Europe and Australia and national coverage of Japan, Switzerland and Austria. And the number of people served annually by agencies was at about 6 million. Now it's hard to count precisely, but the number is at least at several hundred million, reports Chris Harrelson.
