Abstract

도로상의 안개는 대체로 시정거리를 변화시키며 도로 운전자에게 안전에 영향을 준다. 안개 지역 도로에서 연쇄추돌 사고는 주로 후미 추돌 사고이며 사고의 원인은 시거불량과 주행 차량들간의 속도편차 때문이며 주행차량들이 안개시 적절한 주행속도와 차간거리를 유지하는 것이 무엇보다 중요하다. 본 연구에서는 안개 발생시 안전성을 확보할 수 있는 안개 대응 시스템에 대한 설치 효과를 알아보기 위하여 차량 시뮬레이터를 이용하였다. 차량 시뮬레이터 실험을 위한 가상도로는 왕복 2차로 구간인 일반국도 37호선(문산~적성) 눌노천교 주변 1 km 구간으로 운전자 경고등을 25 m와 30 m 간격으로 변경시켰다. 안개 상황은 짙은 안개(시정거리 30 m)와 옅은 안개(시정거리 80 m)로 설정하였다. 피험자는 20대~60대의 성인 남녀 31명을 대상으로 본 실험에 앞서 시뮬레이터에 적응할 수 있는 충분한 연습주행과 사전정보를 제공한 후 주행실험을 한 후 설문조사를 실시하였다. In a foggy day, visible distances depend greatly on the ever-changing concentration of fog. Most of chained rear-end collisions in a foggy day are caused by the significant differences in speeds between vehicles. Then, it is important to minimize the collisions in fog. This study is to estimate the effects of FDWS on drivers' safety behaviors by using a vehicle simulator and a questionnaire survey. A roadway section 1 km long with bidirectional 2 lanes was chosen for the estimation efforts. The test segment was from the Munsan to the Jeokseong county in National Highway 37. Scenarios associated with fog were set as heavy fog. Also, the distance between driver warning lamps was considered by 25 m and 30 m, respectively. The experiment conducted in this study employed the total of 31 adults who were randomly selected from 20- to 60-year old. Before performing the experiment, each subject had enough times to be familiar with the vehicle simulator and was instructed by the guideline of the experiment. After performing the main test, a questionnaire survey was undertaken for each subject.
