Transit Ridership by Transit Authority

Approximately 77 percent of all unlinked transit passenger trips since at least 1996 have been made within the service area of just 30 transit authorities. These 30 top authorities logged 6.9 billion unlinked trips in 2001¹ figure 47). New York City Transit alone reported 2.7 billion, or 30 percent, of all unlinked passenger trips. The Chicago Transit Authority followed with 485 million or 5 percent of all trips [2].

The top 30 transit authorities served a population of about 101 million in 2001 [2]. All transit authorities reporting to the National Transit Database determine their population-served data using definitions of bus and rail service in the Americans with Disabilities Act of 1990 and their own local criteria for other service such as ferryboat and vanpool. Some double counting of populations served occurs, especially among authorities operating in the largest metropolitan areas such as New York City, Los Angeles, Chicago, and San Francisco [2].

According to a Bureau of Transportation Statistics survey,² an average of 71 percent of household respondents indicated they had public transportation available in their area [1].
