본 연구는 주도로의 우선 통행권을 부여하는 비신호교차로의 좌회전 전용차로 설치 권장기준을 정립하기 위해 위험확률기반 모델을 적용하였다. 본 연구에서 적용한 위험확률 모델은 선두 차량의 좌회전과 이를 추종하는 직진 차량간의 잠재적 추돌사고 확률을 기반으로한다. 전이된 음지수 분포와 복합모델 이론을 토대로 진행방향 교통량, 대향 교통량, 좌회전비율의 함수로 2차로도로와 4차로도로에 대해 각각 기 모델(Kikuchi와 Chakroborty 모델)과수정된 모델을 적용하였다. 각 모델은 변수 값(간격수락, 추종시간, 운전자 반응시간 등)들은국내 조건을 반영하였다. 이런 모델을 기반으로 각 좌회전 차량 비율과 운영속도별 최대 허용 확률에 해당되는 진행방향과 대향 교통량을 평가하였다. 이를 통해 2차로도로와 4차로도로에서 좌회전 전용차로 설치 판단을 할 수 있는 기준을 제시하였다.
Abstract
This study is to establish the traffic volume-based warrants of left-turn lanes in unsignalized intersections based on a risk probability methodology. This study applied a risk probability of a potential rear-end collision between a left-turn vehicle and the immediately following through vehicle. With the shifted negative exponential model and the compound probability theorem, the risk probability can be expressed as the function of directional volumes, opposing volumes and the percentage of left-turns for a two-lane and four-land highway, respectively. The warrants of installing left-turn lanes on unsignalized intersections were developed with the risk probability. The warrants define the total approaching and opposing volumes to encourage a left-turn lane as a function of operating speed, percentage of left-turn, and number of lanes.
