项目摘要

This study tries to measure accessibility at building scale on GIS. The following results are obtained. First, as the result of measuring accessibility as the shortest road distance to convenience stores from all buildings in Northeast Area of Adachi Ward, Tokyo, it becomes clear that the accessibility is determined by various factors such as road network pattern, positional relationship between facility and road network, positional relationship among facilities, number of buildings located, and positional relationship between building and road network.Next the accessibility at neighbourhood scale is compared with the accessibility at building scale through a case study of convenience store. It is revealed that the neighbourhood with the largest degree of inner variance has the same degree as the difference in accessibility found in the whole study area. As eighty percentages of the convenience stores are located along streets constructing the boundaries of neighbourhoods or outside th … More em, if the accessibility at neighbourhood scale is measured at a centre of neighbourhood, then average distance becomes longer because the centre is distant place to the location of convenience store.Third, as the case studies of accessibility at building scale, the difference in accessibility among the stories of buildings is analyzed to show the benefit to measure accessibility at building scale. The accessibility measured to stations at building scale also reveals that the opening of a new line called as Tsukuba Express greatly improved the accessibility. The hotels in Kyoto were also evaluated in terms of accessibility at building scale.Fourthly, to measure the accessibility considering the conditions and regulations for road, this study constructs a system that acquires the attribute of road using ArcPad and GPS in the field and transmits the data to the server in my office through edge.Fifthly, this study also constructs a system to measure accessibility using ArcObject. A user clicks a measurement point on digital map represented by ArcGIS. Then the system is able to generate a buffer around the point and count the number of facilities in the buffer and divide population in the buffer in proportion to the area included in the buffer. Finally the system is able to calculate an accessibility index at the measurement point. Less

本研究试图在地理信息系统上对建筑物尺度的可达性进行测量。得到了以下结果。首先，通过对东京高田区东北区所有建筑到便利店的最短道路距离可达性的测量结果表明，便利店的可达性是由路网格局、设施与路网的位置关系、设施之间的位置关系、所在建筑物的数量以及建筑物与路网的位置关系等多种因素决定的，然后通过便利店的案例分析比较了邻里尺度的可达性与建筑尺度的可达性。结果表明，内部变异程度最大的邻域与整个研究区域的可达性差异程度相同。由于80%的便利店位于构成居民区边界的街道上或…之外更重要的是，如果以邻里中心来衡量邻里尺度的可达性，则平均距离会变长，因为中心距离便利店的位置较远。再次，作为建筑尺度可达性的案例研究，分析了建筑物层之间的可达性差异，以说明在建筑尺度上测量可达性的好处。对建筑物规模车站的可达性测量也表明，一条名为筑波快线的新线的开通极大地改善了可达性。第四，在考虑道路条件和法规的情况下，构建了一个利用ArcPad和GPS在野外获取道路属性并将数据通过EDGE传输到我办公室的服务器的系统。用户单击ArcGIS表示的数字地图上的测量点。然后，系统能够在该点周围生成缓冲区，并计算缓冲区中设施的数量，并根据缓冲区中包括的面积成比例地划分缓冲区中的人口。最后，系统能够计算测量点的可访问性指数。较少
