Estimation of Pedestrian Shopping Trips in a Neighborhood by Using a Spatial Interaction Model

This paper contains a report on the application of a spatial interaction model to the prediction of shopping pedestrian flow along the streets of a small district with a shopping center. A model where the shopping trip distributions are determined using a partially doubly-constrained type of model is proposed. This model uses only the cross-sectional data of pedestrian traffic volume and is tested using data from Meinohama district (Fukuoka City, Japan).

Commercial facility location model using multiple regression analysis

This paper describes a simulation model for estimating radical changes in the location of retail facilities that is applied to the Fukuoka metropolitan area of Japan. The model has three important characteristics. First, it clears the retail employment by applying multiple regression analysis and a modified Huff model incorporating distance and population. Secondly, it allocates retail employment for two types of retail stores: convenience-goods stores and shopping-goods stores. Thirdly, it computes commercial floor area for each retail type.

A method for identifying accessibility properties of pedestrian shopping networks

Abstract The purpose of this paper is to propose and test a method for comparing road networks from the viewpoint of pedestrian flows. The method is based on a pedestrian flow model. The road networks can be compared by using the first eigenvector of the transition matrix, which describes pedestrian movement between nodes of the network. In this application, the first eigenvectors of transition matrices are calculated and compared among the road networks of pre-modern cities in Europe, the Middle East, and Japan. The conclusion is that the method for comparing pedestrian road networks by using the first eigenvector of the transition matrix is useful.

A Study on the Utilization of Public Open Space in Consideration of its Building Attributes in Fukuoka, Japan

This study is aimed to suggest an instrument for useful Public Open Space desing. For this purpose, all of 156 POS in Fukuoka, Japan, are investigated by the type to clarify the relation between POS and use of buildings and its circumstance. This shows that (i) Pedestrian Road type should be designed in relation to existing public sidewalk conditions; (ii) General Open Space type should be designed in relation to the location in the lot; (iii) major problems on both PR type and GOS type are occurred in office buildings of which lot area is 1000-1500m2; (iv) ideal design are often in office building; and (v) barricades are placed often in the case of housings. With these results, a flow of consultation, design considerations checklist and amendment of Fukuoka regulations including design guidelines are proposed.

Using computer graphics to compare the visual environments of urban streets in Japan and Taiwan

This research compared the visual environments of urban streets in Japan and Taiwan. Different building standard laws, regional cultures, and traditions create unique townscapes in each country. The research uses three-dimensional computer graphics to express quantitatively the openness of urban space and the characteristics of the visual environments of urban streets in Japan and Taiwan. The analysis of the urban visual environment consists of two parts. In the first part, the characteristics of the visual environments of urban streets in Japan and Taiwan were analyzed by constructing simple town block simulation models, which reflected the floor area restrictions, road setback regulations, site boundary setback regulations, and absolute height controls in each country. In the second part, streets of different width in the center of the commercial districts in Oita City, Japan, and Taichung City, Taiwan, were used to analyze the characteristics of the different visual environments.
