As computer hardware becomes less expensive and more powerful, and as the software continues to grow more sophisticated, transportation agencies are adapting more and more geographic information systems (GIS) solutions to their problems. Since it permits use of spatial relationships, GIS adds hitherto unknown intelligence and sophistication to a transportation data base. The ways in which the Federal Highway Administration (FHWA) is using GIS are listed. FHWA is attempting to use the Census Bureau's TIGER files in transportation work. On-line links between the microcomputer-based Quick Response System traffic demand software and the AUTOGIS/MOSS minicomputer-based GIS are being researched. The Geographic Roadway Information Display System which deals with Interstate system data is also noted. Several FHWA systems use ORNL (Oak Ridge National Research Laboratory) data. GIS use at state level is briefly reviewed. Methods of acquiring and entering data into the system are described. Hardware and software requirements are also described.
