Abstract
Urban planning should be evaluated not only from the side of administration, but also from the side of population in order to reflect population's opinions and their interests. It is surely necessary to include population's urban evaluation model in the urban decision-making process, which quantitatively represents population's value of urban life environment, and by introducing this model it would be easily accomplished to help deciding a plan which is sufficiently incorporated population's dissatisfaction with urban environment and their conflict between various interested groups and several subregions. In this paper, we propose the population's urban evaluation model and describe a method to construct the model and the practical application to Tobata ward in Kitakyushu city. The model is constructed by introducing an additive multiattribute utility function.
The method mainly consists of the following procedures.
1) Constructing a goal hierarchy of urban environment.
2) Gathering population's questionairs which contain relative weights among goals and an unidimensional utility function in each goal.
3) Classifying population into sevaral common interested groups based on their weights and utility functions. In this stage, principal component analysis is usefuly applied.
4) Specifying a group utility function in each group.
5) Specifying the population's utility function by aggregating group utility functions. In this stage, we propose three criterions on which indivdual utility functions are aggregated. One is equality criterion, another is goal utility satisfying criterion, and the other is goal consequence satisfying criterion.
As the result of application to Tobata ward, we obtained the population's urban evaluation model very well expressed problems which are currently confronted in Tobata and that, very effective informations about their welfare are obtained by their urban evaluations.
