The following information about the CD-ROM was abstracted from the
Bureau of Transportation Statistics Home Page:

The National Transportation Atlas (NTA) CD-ROM contains a compilation
of geographic data bases that provide the infrastructure for national
planning and policy initiatives for the U.S. Department of
Transportation. Regional information, by state, is available to users
as well as the entire national infrastructure. The data bases consist
of transportation networks, terminals and other structures, as well as
background boundary and point files. The initial release of the NTA
contains primarily geographic data with very limited transportation
attribute data. Explicit connections between modes and terminals are
not included on this version although the intent is for the NTA data
bases to be expanded with tighter quality control as time goes on.
