Intermodal Passenger Connectivity Database
The Intermodal Passenger Connectivity Database includes records for each passenger transportation terminal, with data on the availability of connections among the various scheduled public transportation modes at each facility. In the aggregate, these data give a measurement of the extent of intermodal connectivity in the passenger transportation system. This database currently includes 1,499 intercity rail stations, airline airports, and ferry terminals. Over 1,000 commuter rail stations and their connections will be added during 2010, with work beginning on rail transit stations and intercity bus terminals.

Starting in 2006, BTS conducts a biennial NFCO survey, from which ferry survey results are combined with operational data from other sources, including the U.S. Army Corps of Engineers and U.S. Coast Guard.
