Abstract
This is the fourth report of the fundamental studies for the method of distribution of regional facilities. The summary of this report is following. 1. According to the results of the questionnaires, the users of regional facilities (shops, hospitals, elementary schools and children playlots) estimate the distance between those facilities and them as following. At distances within 300m, the users estimate the distance satisfactory, on the other hand, at distances over 1, 500m, they estimate the distance unsatisfactory. The relations between the satisfaction rate w(x) and the distance x are Fig.3〜5 and equation (1)〜(4). 2. The relations between the density of regional facilities m_2 and the total satisfaction rate (Z(m_2)=the number of users who estimate the distance satisfactory/the total number of users in regional area) are equation (12) and Fig.11〜14. As is obvious from these figures, the pattern of four graphs are similar to each other. But the total satisfaction rate in case that the distribution pattern of regional facilities is at random are 1〜25% lower than the total satisfaction rate in case of the distribution of equal distances (Fig.15). 3. In order to satisfy a certain satisfaction rate, the density of regional facilities in case of the random distribution are required from two times to four times as many as the density in case of the distribution of equal distances (Fig.16). This indicates that, when we decide the number of facilities in regional area, it is important how to distribute the regional facilities. In this case, a few relations mentioned in this report will be usefull.
