Computer Graphics Applications in Transportation Information Systems.

摘要

This paper reports on the results of the application of interactive computer graphics to those public transportation information systems which answer inquiries from the general public. Primary emphasis was placed on development of a graphics application package to control the existing Transit Information System developed by the Stanford/UMTA research group in the Stanford Industrial Engineering Department. Other areas of investigation included operator interaction with the computer display;sorting and searching a large geographic data base;and the practical limitations of geographic displays on a CRT. The U.S. Census Bureau's DIME data base was analyzed,and an interactive graphics map editor was developed.
