SAINF: A toolbox for analyzing the effect of point-like, line-like and polygon-like infrastructural features on the distribution of point-like non-infrastructural features

Abstract.This paper introduces a GIS-based toolbox, called SAINF, for analyzing the effects of infrastructural features on the distribution of non-infrastructural features. One of the distinct characteristics of SAINF is that it can deal not only with point-like infrastructural features but also line-like (e.g. railways) and polygon-like (e.g. big parks) features. SAINF analyzes these effects with the conditional nearest neighbor distance method and the cross K-function method. First, the paper briefly refers to these methods. Second, the paper illustrates how to use SAINF with an actual example. SAINF can be downloaded via the Internet without charge for non-profit uses.

Formulation of a Quantitative Method to Evaluate the Accessibility to Food Facilities Based on the Load of the Facility Utilization for Analysis of Population Distribution

This paper aims to formulate a quantitative method of evaluating accessibility to the various food facilities, which share the same purpose as meal suppliers but different characteristics, by a common index, for analysis of population distribution. In this study, food facilities are classified into Facility Group I where food facilities cook meals and provide customers with a space to eat meals and Facility Group II where food facilities cook meals but provide no space for eating. By comparing the transportation and initial loads, this approach models the zone where residents find that one facility is more advantageous to the others. This article also compares the loads of facilities between the case where a user makes a round trip to a facility and the case where the user stops by a facility on the way from/to his/her home. The proposed model theoretically explains the zones obtained in the preceding empirical analysis. Analysis on the locations of facilities and the population distribution around a station shows that the facilities of low initial load were located near the station to promote users to stop by, and that areas with small loads tend to have a large share of single-person households.

DEVELOPMENT AND APPLICATION OF A METHOD TO ANALYZE THE PROSPERITY AT THE CENTERS OF LOCAL CITIES FROM, THE VIEWPOINT OF THEIR DISTANCES FROM THE STATIONS

The purpose of this report is to develop a method to analyze the relationship between the centers of cities and the commercial districts near the main stations. The classification using the proposed indexes revealed that the centers of the 66 local cities in Japan have been declining compared with the commercial districts near the stations. Multiple regression analysis showed, that the centers of the cities are likely to decline, if the populations are small, the distances to the main stations are large, the numbers of railway passengers are large, and the prefectural and city halls are far from the centers.

OPTIMUM THREE-DIMENSIONAL URBAN FORM CONTAINING COMPACT CITY SYSTEM

The purpose of this article is to obtain the optimum three-dimensional urban form when compact city system is formed. This article assumed hierarchical district centers and transportation system according to the stage of life needs. As a result, the optimum urban form minimizing travel costs shows that the ratio of vertical travel cost to horizontal one determines the urban area and the distance between the district centers. This result suggests that forming a concentrated high-rise city with skyscrapers depending on elevators may be less efficient than developing the urban area in the horizontal direction by utilizing the transportation.
