Samenvatting
The integration of geographic information system (gis) technology in urban transportation planning and modeling is discussed. The problems faced today and the solution giss could provide are identified. The design considerations and data needs for implementing a gis-based urban transportation analysis system are analyzed and some of the commercially available gis software is evaluated. Emphasis is placed on the use of a gis in model-based transportation applications rather than on other potential uses of gis. Several applications of gis methodology for urban transportation analysis are described.
