SMART Highway 오르막차로 설치 필요성 및 기준 연구 = Necessity of Climbing Lane on SMART Highway and its Design Guidelines

다국어 초록 (Multilingual Abstract)

This study aims to review whether climbing lane installment is needed by analyzing the impact that standard trucks have on traffic according to vertical alignment at SMART highway, and if climbing lanes are required to propose truck speed change curves based on slope length. We used VISSIM simulation model to obtain the speed change of the standard truck on uphill roads. The standard truck on climbing lanes was set for 100kg/kW (170lb/hp) with the entry speeds set and analyzed by 90, 100, and 110 km/h considering the future speed limit of trucks. The results of the research show that under SMART highway circumstance, the 1 and 2% vertical alignment is not needed at the climbing lane but 3% vertical alignment is necessary. In order to install the climbing lane at 3% vertical alignment, the speed change curve of truck depending on slope length of 90, 100, and 110km/h of entry speed is proposed.

국문 초록 (Abstract)

본 연구는 SMART Highway에서 종단선형에 따른 표준트럭의 교통영향을 분석하여 오르막차로 설치 필요성을 검토하고 오르막차로 필요 시 경사길이에 따른 속도변화 곡선을 구하여 제시하는 것을 목적으로 한다. SMART Highway는 미래 고속도로이므로 표준트럭의 실제 주행실험이 불가능하여 VISSIM 시뮬레이션 모형을 이용하여 오르막구간에서 표준트럭의 속도변화를 구하였다. 오르막차로의 표준트럭은 100kg/kW(170lb/hp)로 결정하고 진입속도는 장래 여건을 고려하여 90, 100, 110km/h로 설정하였다. 본 연구결과는 SMART Highway 환경하에서 종단선형 1, 2%에서 오르막차로는 필요하지 않고 3%의 오르막구간에서만 설치 필요성이 있음을 제시하였다. 3% 종단선형에서 오르막차로를 설치하기 위해 진입속도 90, 100, 110km/h에서 경사길이에 따른 트럭의 속도변화 곡선을 제시하였고 오르막차로 설치 위치도 제시하였다.
