A Study on the Development Characteristics with Types of Subway Station Areas in Seoul - A Focusing on the Gangnam-Gu-

The purpose of this study is to delimit the scope of station areas and analyze the indicators and impact of indicators related to density, diversity, and connectivity within connectivity indicators. The research process is deriving indicators related to station areas, analyzing and categorizing the current status of station areas of influence using these indicators, and re-evaluating the indicators and impact indicators for each category of development. The result of analysis based on the indicators of density, diversity, and connectivity classified the station areas of influence into three categories: high-density and high-connectivity areas (10 zones), medium-density and medium-connectivity areas (13) zones), and low-density areas (6 zones). It was found that station areas of influence with higher density and connectivity tend to be concentrated along major thoroughfares, such as Teheran-ro, while development is more active in the relatively lower-density areas situated behind these major roads, where the proportion of new buildings is relatively low. The analysis of the characteristics of newly constructed buildings by type shows that higher density and accessibility are associated with higher floor area ratios and building heights, whereas lower density and accessibility are significantly linked to lower values in these metrics. Finally, through regression analysis, the indicators influencing development were re-evaluated. The results showed that higher building heights, floor area ratios, and residential population ratios are associated with increased new construction activity. Consequently, it can be observed that higher existing urban density and building obsolescence further promote the activation of station areas of influence development station areas of influence with high levels of obsolescence and density should establish comprehensive management strategies, such as integrated development guidelines for the entire area. to prevent indiscriminate development. Conversely, for station areas of influence with high density and low obsolescence, it would be more efficient to develop management strategies focused on individual buildings or clusters of outdated structures.
