초록

지하도로의 유입연결로 합류부는 지상도로와 달리 터널로 인하여 시계확보에 제약을 받는다. 본 연구에서는 시계확보에 관련 설계요소가 합류부 주행에 미치는 영향을 분석하기 위하여 주행 시뮬레이터를 활용한 가상주행실험을 수행하였다. 가상주행환경 구축시 시계확보 설계요소를 시나리오에 반영하기 위하여 갈매기차로 길이와 본선차량 접근속도를 시나리오로 구분하여 운전자 주행행태를 분석하였다. 시나리오간 속도 측면의 분석지표와 차로변경지점, 운전자 주시 비율 분석결과는 일관성 있는 방향으로 도출되었고, 통계적 유의성을 검토하였다. 그 결과, 본선 접근속도가 더 높은 시나리오에서 갈매기차로 길이에 의한 특정 시나리오 사이에 운전자 주행행태의 차이가 있는 것으로 나타났다. 이러한 결과를 바탕으로 지하도로 유입연결로 합류부의 주행안전성 향상을 위한 설계방향과 시사점을 제시하였다.

Unlike ground roads, the on-ramp merging section of underground roads cannot be seen by drivers of main road due to tunnels. In this study, a driving simulator was used for analysis, and virtual driving experiments were carried out to assess the driver's visibility for different design factors. The driver's driving behavior was analyzed by setting scenarios considering the length of chevron markings and the approach speed from the main road. The results of the analysis were used to determine the design factors for ensuring visibility when constructing the virtual driving environment for each scenario. These factors, including speed, lane change points, and driver's gaze ratios, were reviewed for significance using a statistical approach. As a result, in scenarios with a higher approach speed from the main road, it was discovered that there was a difference in driver's behavior between specific scenarios depending on the length of the section with chevron markings. Based on these findings, this study suggests implications and feasible solutions to improve driver safety on the on-ramp merging section of underground roads.
