Abstract

Recently, bicycle accidents have increased with the ever-increasing number of cyclists. Bicycle accidents occurred frequently in intersections, and the perpendicular collision between a right-turning car and a crossing bicycle was the most prevalent accident type. In particular, the collision was caused by motorists' carelessness. In other words, the accident-involved motorists did not pay sufficient attention to a bicycle crossing behind them. Another cause was a cyclist's higher speed than pedestrians. This paper evaluated the potential risk of the collision between right-turning cars and crossing bicycles based on simulation experiments, with motorists' speed and carelessness focused on. Consequently, it was found that to reduce the potential risk of the collisions a motorist should slow down and pay more attention to the rear sight by turning his/her head.

자전거 교통사고는 이용수요의 증대와 더불어 지속적으로 증가하고 있는 추세이며, 기존 교통사고 자료를 통해 자전거 교통사고의 특성을 살펴보면 사고발생 지점은 주로 교차로 내부이며, 사고형태는 측면직각충돌사고가 빈번한 것으로 나타났다. 본 연구에서는 교차로 내에서 발생되는 우회전차량과 횡단자전거 간의 상충위험성이 발생하는 원인으로 우회전차량 운전자의 주위확인행태와 차량속도로 가정하고 시뮬레이션 분석을 이용하여 그 위험성을 제기하고자 한다. 연구 결과 우회전차량의 주행속도가 낮을수록, 또한 운전자가 고개를 돌려 적극적으로 우측 후방을 확인할수록 상충위험성은 감소하는 것으로 나타났다.
