More than one-half of all U.S. transportation terminals offer intermodal passenger connectivity among at least two scheduled passenger transportation modes, according to a new passenger connectivity database released by the U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS).

The Intermodal Passenger Connectivity Database (IPCD) shows that 68% of terminals in urbanized areas offer intermodal connections, but only 7% of terminals in rural areas offer the same service. Rail stations are the most likely terminals to offer connections, while airports are the least likely terminals to do so.

The complete IPCD database contains details about connections at more than 7,000 passenger terminals, including the type of connecting facility, the geographic location of the connection and the types of connecting modes.

Release of the IPCD completes a five-year BTS effort to collect data on intermodal connections in the passenger transportation system.
