THE ROLE OF GEOGRAPHIC INFORMATION SYSTEMS IN REGIONAL TRANSPORTATION PLANNING

Geographic information systems (GIS) are gaining popularity in transportation planning agencies, especially among metropolitan planning organizations. The extension of GIS into transportation comes from the passage of the Intermodal Surface Transportation Efficiency Act, the Clean Air Act Amendments, and legislation by states that mandate the development of transportation programs to reduce traffic impacts. Traditionally, transportation modeling of traffic impacts, calculation of vehicle emissions, and consideration of wider transportation planning effects, including transit, have employed different modeling techniques, often in different agencies or in separate sections within an agency. The results from these modeling and planning exercises have more often than not been displayed on different map bases, utilizing different graphic programs to represent the data. The requirements of federal and state programs are encouraging modelers and planners to consider more consistent methods of data integration and display, hence the growing interest in GIS. This paper, which appears in a compendium of conference papers, discusses the role of GIS in regional transportation planning, including data integration issues, the configuration of transportation networks for use with GIS, and the linkage of transportation models to GIS.
