This paper derives an analytical expression of the total benefit of facility users under the following conditions: (i) the behavior of facility users follows an origin-constrained spatial interaction model, and (ii) the distribution of facility users in a network space is represented by polynomials. We first represent the total benefit of facility users in a network as a definite integral. We then demonstrate that a part of integrand in the definite integral, which is the natural log of the accessibility, can be represented by the infinite series of exponential functions and that the analytical expression of the total benefit is derived based on the infinite series.

It has been said that urbanization in modern city causes heat island phenomenon, decreasing amount of green coverage not only at the edge of urbanized areas but inside of urbanized areas. Therefore, eco-friendly urban planning which is expected not only to mitigate heat island phenomenon but to increase the green coverage. This research analyzed the surface temperature distribution of urban residential areas in Nagoya city, focusing on the city as a whole and each district as individual. Our result reveals that the smaller building coverage ratio and floor area ratio become, which may produce more parks and green areas, the lower surface temperatures become. In addition, clusters of trees significantly lower surface temperatures.

Small-scale municipalities are faced with the difficulty of reduction of public works. In such a situation, it is<br>important to clarify how each measure contributes to a whole target to conquer the difficulty in the process in which a comprehensive plan is formulated. This research examines the process of formulation of the comprehensive plan of Kitadaitou, Okinawa. We discuss the framework using a simulation based on several scenarios in order to apply other municipalities.
