Abstract

The aim of this research is to analyze factors affecting bicycle accidents using the PLS structural equation. Accident types in this study were categorized into total accidents, serious injuries including death, and light injuries which occurred at nationwide Si Gun Gu. It was found that urbanization was the main factor for bicycle accidents through the accident models developed in this study. Population, ratio of economically active population, density of intersections, ratio of urbanized area, commercial and industrial land-uses, number of drive license holders, number of education institutions, number of parks were the main factors causing bicycle accidents. Besides, length of bicycle roads, number of bicycles, and ratio of bicycle as mode choice also increased bicycle accidents.

본 연구는 자전거사고에 영향을 주는 요인들을 분석하기 위해 PLS 구조방정식을 이용하여 자전거사고모형을 개발한다. 본 연구에서는 자전거사고를 전국 시 군 구를 대상으로 전체 사고건수, 중상이상 사고, 경상사고로 사고유형을 구분하였다. 본 연구에서 개발된 사고모형들을 통해 자전거사고의 주요 원인들을 살펴보면 도시화의 확대가 자전거사고의 가장 큰 요인임을 알 수 있다. 자전거사고모형들에 포함된 주요 요소들을 살펴보면 인구수, 경제활동인구비율, 교차로밀도, 시가화 면적비율, 상업과 공업의 토지이용, 운전면허소지자, 자동차등록대수, 교육기관 설립수, 공원수 등의 증가가 자전거사고의 증가로 이어졌다. 또한 자전거도로연장, 자전거보유대수, 자전거수단분담률의 증가 등 각 지자체 별로 활성화되고 있는 자전거이용의 확산 역시 자전거사고를 증가시키는 주요 요소들로 밝혀졌다.
