초록

본 논문에서는 도심항공 모빌리티(UAM)를 우리나라 수도권에서 운용하기 위해 필요한 수직이착륙장의 위치를 선정하고 평가하였다. 통근통학 인구수 조사 데이터를 이용해 수요 데이터를 분석하였으며, MATLAB을 이용해 지도상에 표현하였다. 또한 데이터들을 군집화하기 위해 MATLAB에 내장되어있는 K 평균 알고리즘 함수를 이용해 수직이착륙장의 위치로 선정할 군집의 중심을 파악하였으며, 실루엣 기법을 이용해 군집화의 정확도와 신뢰도를 평가하였다. 또한 선정된 수직이착륙장의 위치가 실제 수직이착륙장 설치에 적합한지 위성 지도를 이용해 확인하였으며, 그 위치가 설치 불가능한 위치에 있는 경우 위치 조정 과정을 통해 최종 수직이착륙장의 위치를 선정하였다.

In this paper, locations of vertiports were selected and evaluated to operate urban air mobility (UAM) in the Seoul metropolitan area. Demand data were analyzed using the data from the survey of commuting population and were marked on a map using MATLAB. To cluster the data, the K-means algorithm function built in MATLAB was used to identify the center of the cluster to as the location of vertiports, and using the silhouette technique, the accuracy and reliability of the clustering were evaluated. The locations of the selected vertiports were also identified using satellite maps to ensure that the locations of the selected vertiports were suitable for the actual vertiport location, and, if the location was not appropriate, final vertiports were selected through the repositioning process.
