초록

This study is a basic study on the effect of the GTX-A line on the metropolitan area. The main purpose of this study is to examine the range and intensity of the GTX-A line's influence on the accessibility of the surrounding areas in the dimension of urban spatial networks for the entire Seoul metropolitan area including Seoul City and Gyeonggi-do. To the purpose end, first, the expected effect on accessibility that appeared in the initial GTX-A line plan was derived by literature review. Next, using spatial analysis based on ground and underground spatial networks for the entire Seoul metropolitan area, the GTX-A line was compared and analyzed before and after the establishment. Finally, the expected effect of the initial GTX-A line plan on the accessibility of the surrounding area was discussed based on the range and intensity of the change in accessibility by the GTX-A line derived in the previous step. As a result of the analysis, it was shown that the accessibility of the area around the GTX-A line was improved, the range and intensity of change in accessibility were different by regions. It was found that the regional range and intensity of accessibility improvement in the regions at the start and end of the GTX-A line were higher than in other regions. On the other hand, it was found that the intensity of accessibility improvement weakened as it went to the middle point, and in some regions meaning the intensity of accessibility only affected accessibility locally. Considering the results of this analysis, it is expected that the construction of the GTX-A line can improve traffic congestion and welfare in the Seoul metropolitan area, but it is still skeptical about the development of compressed cities through TOD at each surrounding of stations of GTX-A line.
