The report documents a data base system created at the National Bureau of Standards. The National Network Data Base System (NNDBS) provides information on flows of freight and passengers throughout the transportation system of the United States. It consists of a set of Fortran programs written for the NBS Univac 1108 (but transportable) and some basic data tapes. In addition to providing basic data on the transportation network, the NNDBS can produce modal splits, aggregations over certain zones in the U.S., and is capable of easy extension to other uses. The report is intended as a user's guide and includes discussions of the data tapes and each of the programs. Complete listings and tape formats are also included.
