Abstract

Two primary tools to study park use are surveys and direct observation. Existing methods, however, are limited in terms of considerable costs in both time and money and the personal bias of respondents or observers. These limitations result in a lack of efficient, reliable, and affordable tools to investigate park use. This study explores the reliability and usability of unmanned aerial vehicles(UAVs) to explore park use in urban parks in Busan metropolitan city. By comparing with a systematic observation tool, SOPARC(System for Observing Play and Recreation in Communities), this study finds that the number of park users observed by two different techniques are highly correlated and not significantly different with each other. In addition, both methods show a high level of test-retest reliability. Comparing to existing methods, the UAV-using observation tool could cover larger target areas and is suitable to count park users in a more reliable and efficient way and map their use patterns, although it is weak in collecting detailed user information and surveying under poor conditions such as rain. Thus, the UAV method could complement direct observation. This study suggests practical implications of a UAV method to study park use.

공원 이용행태는 주로 이용자 설문이나 행태 관찰을 통해 조사되어 왔다. 하지만 기존 방식들은 시간과 비용이 많이 소모되고, 응답자나 조사자의 주관에 취약하다는 한계를 갖는다. 이로 인해 개별 도시에서 활용할 수 있는 체계적이고 일관된 공원 이용 실태 조사기법이 부족한 실정이다. 이에 본 연구는 부산광역시 도시공원을 대상으로 공원 이용 조사를 위한 무인비행장치의 활용성을 파악해 보고자 한다. 특히 기존에 신뢰성과 타당성이 검증된 체계적 관찰 기법인 여가활동 관찰 기법(SOPARC)과 비교하여 본 기법의 유용성을 살펴본다. 연구결과, 무인비행장치를 이용한 관찰결과는 SOPARC의 결과와 매우 높은 상관성을 보였으며, 통계적으로 유의한 수준에서 차이가 없는 것으로 나타났다. 또한 두 기법 모두 높은 수준의 검사-재검사 신뢰도를 나타냈다. 무인비행장치를 활용한 방법은 기존 관찰기법들에 비해 넓은 지역을 관찰할 수 있고, 정밀한 이용자 수 조사 및 공간 시설 이용패턴 파악에 적합한 장점을 가진 반면, 자세한 이용자 정보를 파악하기 어렵고, 날씨 등 조사 여건의 제약이 많다는 한계를 보였다. 따라서 두 기법을 상호보완적으로 활용하는 것이 바람직할 것이다. 마지막으로 무인비행장치를 활용한 공원 이용 조사 시 유의할 사항들을 제안하였다.
