서울시 자전거 교통사고의 물리적 환경요인 분석

초록

Car-dependent cities have many urban problems, such as traffic jams, air pollution, and traffic accidents. In contrast, non-motorized bicycles are a sustainable mode of transportation. During the past decade, the city of Seoul has invested heavily in bicycle infrastructures, including public bike-sharing programs and bicycle road infrastructure. However, as bicycle users have increased, bicycle accidents have increased as well. The problem of bicycle accidents can be more serious than pedestrian traffic accidents because most bicycle riders often do not wear safety equipment. Therefore, this study analyzes the physical environmental factors of bicycle accidents using the Traffic Accident Analysis System (TAAS) data (2017-2019) and suggests policy implications for the safety of bicycle users. The major physical environmental factors that affect bicycle accidents are crosswalks and three-way intersections. In addition, this study confirms that bicycle infrastructures are critical factors in bicycle accidents. The bicycle-only roads show significant associations for accidents between bicycles and cars. In contrast, the bicycle-pedestrian roads show significant associations for accidents between bicycles and pedestrians. The analysis results also show significant associations between bicycle accidents and bicycle facilities such as convenience facilities for bicycle users, incomplete bicycle roads, and trees on bicycle roads. Finally, this study discusses policy implications to improve the safety of bicycle users.
