The structure of residents' subjective evaluation of the urban environment is studied by using fuzzy measures. The purpose is twofold : identification of local individualities and analysis of interactions between items of evaluation. The comprehensive evaluation is modeled by the Choquet integral, and fuzzy measures are identified by the convex quadratic programming. The data used in the analysis is obtained by the questionnaire survey carried out by the municipal government of Tokyo in 1991. Several problems such as treatment of subjective data given in the ordinal scale and interpretation of computed fuzzy measures are discussed. It is proved that the weight of each item is very small, but the weights of unions of two or three items are large enough to evaluate the environment, and the important combinations of items depend on local individualities.
