Abstract

Demand Responsive Transport (DRT) is a transport system that manages in response to user demand without fixed routes and plans. Compared to the existing public transport, which has fixed routes, it is highlighted as an effective transport system in non-profit routes and resilient in pandemics by covid-19. However, the indiscriminate introduction of DRT causes operation costs to be higher and routes to overlap. Furthermore, related works have limitations that it is difficult to apply to the mixed area between the rural and urban areas which generally exist in South Korea. Therefore, we analyze DRT types for each route and spatial patterns for DRT operation. Inspecting Namyangju, South Korea, we re-define DRT types through hierarchical clustering and analyze spatial features using DBSCAN clustering after determining board-alight clusters by k-means clustering. As a result, we not only define an inter-neighborhood route as peak DRT, complementary DRT, alternative DRT, and needless a DRT but find a spatial pattern of time zone. It is appropriate to introduce peak DRT and alternative DRT or needless a DRT for commuting and transferring in urban and suburban. Whereas in rural areas, it is apposite to adopt the complementary DRT for feeder service. It may be utilized as data in the rural-urban mixed areas located in South Korea.

수요응답형 교통(Demand Responsive Transport, 이하 DRT)은 고정된 노선 경로나 운행계획표 없이 이용자의 수요가 발생했을 때 대응하여 운행하는 교통체계로 비수익 노선에서 효율적으로 운행할 수 있으며, 코로나-19가 확산된 판데믹 상황에서 기존 대중교통과 비교하여 회복탄력적인 교통수단으로 각광 받고 있다. 그럼에도 불구하고 무분별한 DRT 도입은 운행비용과 중복 노선을 증가시키며, 또한 기존 연구의 도입 논의지역은 국내에 대체로 존재하는 도농복합도시에 적용하기 어려운 한계점이 존재한다. 따라서 본 연구는 이를 해소하고자 DRT 도입 여부 및 유형과 DRT 운영을 위한 공간적 패턴 분석을 수행하였다. 이를 위하여 경기도 남양주시를 대상으로 Hierarchical Clustering을 통해 DRT 도입 유형을 정의하고 K-Means Clustering을 통해 평일 승하차량을 기반으로 승, 하차 클러스터를 규정한 후, DBSCAN Clustering을 통해 유사한 특성의 정류장이 밀집된 클러스터를 도출하여 공간적인 특성을 분석하였다. 분석 결과, 남양주시 소 생활권 간 운행노선을 첨두 DRT, 노선확충형 DRT, 노선대체형 DRT 등 3가지 노선과 DRT 미도입으로 정의하고 주요시간대 별 공간적인 패턴을 확인하였다. 이를 통하여 도시 및 시가화 지역에는 첨두 DRT, 노선대체형 DRT 혹은 DRT 미도입이 적절하며 통근, 통학 및 환승통행을 수행해야 하며, 농촌 지역에는 노선확충형 DRT를 도입하는 것이 적절하고 지역중심으로의 통행을 제안하였다. 본 연구는 DRT 유형에 대해 세분화하여 제안하였기에 국내 다수 존재하는 도농복합도시에서 DRT 도입을 위한 기초자료로 활용할 수 있다.
