Abstract
This article describes the theoretical foundation, fundamental structure, and application of an integrated planning tool for evaluating the multicriteria environmental sensitivity (ES) of urban road networks. The tool is an integration of the environmental sensitivity methodology (ESM) concept, analytic hierarchy process (AHP), fuzzy set theory (FST), knowledge‐based expert systems (KBES), and geographic information system (GIS). A case study application of the tool, using the road network for the city of Geelong in Victoria, Australia, is described. The results of the case study indicate the potential utility of the tool for assessing the ES of an urban road network at a local level, identifying problem locations, and specifying the possible causes of those problems. In addition, it is found that the typical AHP expressed more powerful capability in differentiating links according to their composite ES characteristics than the fuzzy compositional AHP.
