초록

본 연구는 최근 활용도가 주목받고 있는 드론을 활용하면 기존 현장조사장비로는 불가능했던 수준의 정밀한 영상자료 수집이 가능하다는 점에 착안하여 진행된 "드론활용 사례연구"의 하나로서, 접근로에서 황색신호 점등시 운전자의 의사결정 패턴을 분석하기 위해 드론 촬영 영상을 활용하였다. 본 연구에서는 먼저 접근로상의 딜레마구간을 파악하고, 황색신호점등 시 실제 운전자들이 정지 혹은 통과하는 의사결정 기준선을 파악하고, 이를 적정 황색신호 셋팅값에 의한 기준선과 비교하여 차이가 있는 구간을 "위험통과구간"으로 정의하고자 하였다. 또한, 이를 개선하기 위한 방법으로 황색시간 재설정 및 특정한 가이드 노면표시를 도입하여 운전자들이 안전하게 정지 혹은 통과 결정을 할 수 있도록 돕는 방안을 제안하였다.

This study was a drone-utilized case study motivated by that drones can obtain sophisticated video image data previously not feasible. The dilemma zones on selected intersection approaches were identified and locations of drivers' decision making to stop or go at the onset of yellow were determined by analyzing drone video images. The gap between the drivers' decision making location and invisible stop/go border line provided by the yellow time interval was defined as "risky passing zone". To improve the dilemma zone safety problems, re-optimization of yellow time intervals and introduction of new pavement marking that can help drivers decision making on yellow indication are suggested.
