A model is developed to aggregate transportation analysis zones (TAZs) using fuzzy set theory and spatial analysis tools found in geographic information systems (GISs). The purpose of the model is to provide analysts with standardized mathematical and computerized approaches for network design. Approaches for modeling zonal homogeneity are compared, and a model for evaluating zone shape is presented. Implementation of these models is discussed for Arc/Info and Atlas GIS. The focus of the work described is on aggregating TAZs, but the model applies equally well to creating TAZs from smaller units like census blocks.
