A Group Model Building Process to Integrate Land Use,Transportation, and Air Quality Planning in Las Vegas, Nevada

摘要

This paper uses the framework proposed by Rouwette et al. (2002) to describe the group modelbuilding stage of a project to integrate land use, transportation and air quality planning in a rapidlygrowing metropolitan area. The paper has two purposes: compare this case with the findings ofRouwette et al. (2002), and test the framework for reporting about group model buildinginterventions. Group modeling was used in this intervention for problem definition, causaldiagramming, and quantification of “fuzzy” relationships between variables. Quantification wasdone “behind the scenes” by the consultants. Model development took 18 months. The casesupports the findings of Rouwette et al. (2002) that show a strong connection between group modelbuilding and client learning about the problem. Consensus about the problem and commitment tothe modeling approach also increased. The context–mechanism–outcome framework was useful fororganizing information about the case, although some of the variables need to be defined moreclearly.
