초록

이 연구의 목적은 서울대도시권을 대상으로 광역적 차원의 철도 및 버스 네트워크와 결절점-장소 상호관계를 고려한 TOD 유형화를 실시하고, TOD 유형과 대중교통수단분담률의 관계를 분석하는 것이다. 이를 통해 서울대도시권의 광역버스까지 반영된 새로운 유형을 도출하여 TOD 개발 잠재력을 확인하고, TOD를 형성하는 요소가 대중교통 이용증대효과와도 연관이 있는지 파악하고자 한다. 연구결과는 향후 확장될 광역철도, BRT 등 다양한 교통수단과 토지이용의 통합적인계획을 위한 TOD 정책에 기초자료로 활용될 수 있을 것이다.

This study aims to develop the typology of transit-oriented development (TOD) based on rail and rapid bus transit networks and identify the differences in transit modal split among TOD types for the Seoul Metropolitan Area. Using cluster analysis with features derived from node-place model and TOD 3Ds (Density, Diversity and Design), this study classifies 1,013 administrative dongs with wide-area transit access into 5 types, namely, Center, High-density, Hybrid, and Suburban TOD types, and TAD (Transit-adjacent Development). The findings show that firstly, there is a positive correlation between node- and place-index. However, some imbalances, particularly in the urban center, highlight the need to achieve TOD on a metropolitan scale via continuous monitoring based on the relationship between transit networks and land-use. Secondly, neighborhoods within the suburban TOD type exhibit greater rapid bus based accessibility, leading to a higher transit modal split than that in TAD type. Lastly, neighborhoods categorized as TAD exhibit a lower transit modal split owing to the combination of low transit availability and urban density. These types have contrasting levels of rail- and bus-based accessibility and varying spatial distributions. The results emphasize that TOD can help reduce private car usage and increase transit ridership, thereby helping achieve carbon neutrality within cities. However, given the existing transportation and land-use conditions within the Seoul Metropolitan Area, comprehensive TOD polices that integrate both bus and rail transit networks are required.
