교통망체계의 종합접근성 분석에 관한 연구 = 강남구를 사례로 하여

다국어 초록 (Multilingual Abstract)

The purpose of this study is to develop the integrated accessibility model for transportation network systems, using GIS technique. In this study, the different measurement of accessibility models are used according to the types of transportation systems such as subway and road network systems. This study is also attempted to transform the discrete nodal pattern of accessibility into the continuous grid pattern.
The results of this study are as follows.
First, the nodal accessibility of subway network system and that of road network system show very different in terms of spatial distribution of high and low values of accessibility. The high rank nodes for road network system are concentrated at the middle part of Kangnam-Gu, while the high rank nodes for subway network system are located along the subway line and transfer stations.
Second, integrated accessibility values for entire area as a continuous pattern would be much better in order to represent the characteristics of the spatial structure of accessibility.
This study has some limitation in terms of measuring the nodal accessibility of road network systems. The study area is limited only the boundary of Kangnam-Gu, as a closed road network system. Further, to improve accessibility analysis using GIS techniques efficiently, it is necessary to build database related various types of transportation systems.
