초록
본 연구에서는 고속도로 VDS 검지기 데이터를 활용하여 터널 구간과 일반 구간의 도로용량을 산정하여 비교하였으며, 터널 특성 요인에 따라 분류된 터널유형별 터널 진입 전 대비터널 내부 도로용량 감소율을 분석하였다. 터널 구간과 일반 구간의 도로 용량을 비교하기 위해 5분 단위 VDS 검지기 데이터에 Product Limit Method(PLM)을 적용하였다. PLM으로 도출된터널 구간 및 일반 구간의 도로 용량을 비교한 결과, 터널 구간은 일반 구간 대비 도로 용량이약 6.5% 감소하였다. 터널 유형 분류를 위해 터널 연장과 터널 내 차로수를 변수로 활용하였으며, 각 기준에 의해 분류된 터널 집단별 도로 용량 감소율에는 차이가 있었다.
Abstract
In this study, the capacity of the tunnel and the general section was calculated and compared using the VDS detector data, and the decrease rate in capacity of the tunnel section was analyzed by tunnel type. To compare the capacity of the tunnel and the general section, the Product Limit Method (PLM) was applied to the VDS detector data. As a result of comparing the capacity of the tunnel and general section, the capacity of the tunnel section decreased by about 6.5% compared to the general section. To classify the tunnel type, the tunnel extension and the number of lanes were used as variables, and there was a difference in the decrease rate of capacity by tunnel group classified by each criterion.
