Abstract

Mobility and accessibility are fundamental to social participation for wheelchair users, profoundly influencing their quality of life and overall satisfaction. Despite the increasing proportion of individuals with physical disabilities within the population, research on travel behavior and trip chain analysis has predominantly focused on non-disabled individuals, leaving a gap in empirical studies on the activity and mobility characteristics of wheelchair users. This study addresses this gap by employing a multidimensional approach, integrating mobile phone GPS data with mobility surveys to analyze the activity patterns of wheelchair users while considering both subjective perceptions and spatial mobility. Utilizing a density-based clustering technique, we identified stay and movement points from GPS trajectory data, which lacked clear distinctions between trips and purposes, to construct trip chains. This analysis allowed us to derive activity characteristics based on stay types and mobility characteristics by trip purpose for wheelchair users. The results reveal that wheelchair users spend a significant portion of their day at home and frequently visit locations near their residence, indicating a reliance on home-centered living. Furthermore, even when venturing out, over half of the visited locations were repetitive, with a notably low frequency of visits to new places. These findings highlight the fixed activity patterns and limited mobility of wheelchair users, underscoring the importance of community efforts to expand their activity space and enhance opportunities for social participation. This study provides valuable policy insights for ensuring the mobility of transportation-disadvantaged individuals, including those with disabilities, and improving access to various facilities.

휠체어 이용 장애인은 전체 인구 대비 매해 꾸준히 증가하고 있지만, 생활패턴 및 트립체인 분석은 주로 비장애인에 주로 집중되어 있어 이들의 활동 및 이동특성에 대한 실증적 연구가 미비한 상황이다. 따라서 본 연구에서는 휠체어 이용 장애인의 휴대폰 GPS 데이터와 이동권 설문조사를 활용하여 사회인구학적 특성과 공간적인 이동성을 포함하는 활동패턴을 분석하고자 하였다. 본 연구에서는 밀도 기반 클러스터링 기법을 활용하여 통행 및 목적 구분이 되지 않은 GPS Trajectory 데이터를 체류 및 이동 지점으로 구분하여 트립체인을 구축함으로써 휠체어 이용 장애인의 체류 유형별 활동특성과 목적통행별 이동특성을 도출하였다. 분석 결과, 휠체어 이용 장애인은 하루의 상당 부분을 집에서 보내며, 자주 방문하는 시설이 주거지 근처의 장소로 한정되어 있어 주거지 중심의 생활에 의존하는 경향을 확인하였다. 또한 외출을 하더라도 방문 시설의 절반 이상이 반복적이며 새로운 장소를 방문하는 비율이 낮은 것으로 나타났다. 이는 휠체어 이용자의 고정된 활동패턴과 제한된 이동성을 보여주며, 이들의 활동 공간의 범위를 넓혀 사회적 참여의 기회를 높이기 위한 지역사회의 노력이 요구됨을 시사한다. 본 연구의 결과는 장애인을 포함한 교통약자의 이동성 보장과 다양한 시설로의 접근성 향상을 위한 정책적 시사점을 제공하는 데에 의의가 있다.
