Abstract
The new local transportation facilities provide a lot of influences on the multi-level of regional inhabitants' lives. The road improvement in depopulated areas, in particular, contributes to the promotion of level of living services. On the other hand, the demerits on the traffic safety and the environmental preservation should be evaluated. In this study the first aim is to construct the method in terms of fuzzy modeling which evaluates the subjective notion on the various factors of living environment. Such factors provide the degree of improvement and degree of satisfaction on the living environment in terms of the transportation facility improvement such as the improvement of access from depopulated areas to a local kernel city. The subjective values are indicated by the fuzzy measures in order to assess the vagueness which the inhabitants possess. The evaluation examined by several measures with the range from the possibility measure to the necessity measure. The accuracy of the proposed method and procedure were verified by the case of an actual construction of the tunnel for the improvement of the accessibility among the local towns.
