Abstract
ICT infrastructures such as wired/wireless information networks are poised to play an important role in meeting these demands, and there is an urgent need to facilitate nationwide ICT infrastructure immediately. Since installation of such ICT infrastructures takes a large amount of time and expenditure, the selection of installation area is an important issue. Low-usage facilities can cause huge problems for businesses in terms of investment efficiency, and it takes time to select areas because we need to consider how to estimate the potential demand and how to diffuse the installation for thousands of municipal areas across the nation. This paper evaluates the micro area selection method which is previously proposed with ICT infrastructure propagating based on commuting flows. A comparison with the performance of a WiMAX service currently in use for several areas induces the improved method.
