Application of Geographic Information Systems in Traffic Planning with a special emphasis on Decision Support

The Ph.D. project concerns the use of Geographic Information Systems (GIS) for traffic planning with a special emphasis on decision support modelling. The study comprises two main areas: (1) Analyses of the applicability and possible advantages from the use GIS in the planning process. A GIS-based decision support system that includes traffic economic effects, accidents, local environmental effects, and the effects on the land-use is developed. Other effects may also be included. (2) Clarification of how uncertainties in connection to the evaluation of transport infrastructure investments can be treated. Approaches for the inclusion and quantification of uncertainties in the traffic planning model complex are evaluated. The project is concerned with multi-modal planning processes.
