본 연구는 자전거도로에서의 사고 예방 및 위험요소 관리를 위해 이동형 IoT 센서 장비 운용을 위한 자전거도로 위험 감지요소 선정 및 서비스 적용방안을 제시하였다. 전문가 심층조사를 통해 12개의 자전거도로 위험 감지요소를 도출하였고, 도로·교통 전문가 30명을 대상으로 Fuzzy AHP 기반의 중요도 분석을 수행하였다. 그 결과, 시인성이 낮으나 사고 위험성이 높은 포장상태 손상(전체 1순위), 환경적 장애요소(2순위)가 최상위권에 선정되었다. 중상위권으로는 단절노선 발생(4순위), 인공적 장애요소(5순위), 유효 폭(6순위), 배수 불량(7순위) 등 시설관리 요소들이 선정되었다. 노면표시 손실(11순위), 여유공간 폭(12순위)과 같이 직접적인 사고유발 요인이 아닌 요소들은 최하위권에 선정되었다. 이를 토대로 자전거도로 위험 감지 서비스 적용방안 및 실시간성에 따른 서비스 운영전략을 함께 제시하였다. 향후 자전거도로 유형별 분석, 서비스 실증 및 시범운영 등 후속연구가 활발히 진행되어, 국민들이 안전하게 이용할수 있는 자전거도로 운영 및 관리가 이루어지길 기대한다.
Abstract
This study selected bicycle road hazard detection factors for mobile IoT sensor device operation and developed service application plans. Twelve bicycle road hazard detection factors were derived through a focused group interview, and a fuzzy AHP-based importance analysis was conducted on 30 road and transportation experts. As a result, ‘damage to pavement’ (1st overall) and ‘environmental obstacle’ (2nd) with low visibility but a high risk of accidents were selected the most. The factors in terms of facility management, such as ‘disconnected route occurrence’ (4th), ‘artificial obstacle’ (5th), ‘effective width’ (6th), and ‘poor drainage’ (7th), were selected as the upper and middle areas. Factors that are not direct accident-inducing factors, such as ‘loss of road markings’ (11th) and ‘free space width’ (12th), were selected the least. Based on this, a plan was presented to apply the bicycle road hazard detection service and a service operation strategy according to real-time performance. Nevertheless, follow-up studies, such as human behavioral analysis based on bicycle operators, analysis according to the bicycle road type, service demonstration, and pilot operation, will be needed to develop safe bicycle road management is expected.
