Considering Network Demand Issues in GIS Transportation Data Modelling and Geographic Data Base Design

要旨

Aim of the research presented in this paper is to assist Transport Planners manipulate spatial information involved in Travel Demand Modelling (TDM) by exploiting the advances of contemporary Geographic Information Systems (GIS) tools. This may be achieved by establishing a standard data model prototyping the transport entities used in transportation related activities. Significant amount of information related to Urban Transport Planning System (UTPS) models could be exchanged with GIS management systems. Identifying this kind of data exchange may lead to refining the design of existing transportation data models. In this respect, EMME/2, an interactive-graphic state-of-the-art multimodal UTPS, being used by numerous transportation authorities worldwide, has been employed as a reference example, to provide valuable experience toward this direction.
