The highway weaving section is a point where there is a conflict caused by entry and exit vehicles. In order to minimize the impact on the main line, an accumulation line should be installed. The design speed of the collecting part is 50 km/h, but the actual driver does not have proper deceleration according to the design speed. In this study, considering the driving behaviors, the design specification, and the driver 's viewing angle, the appropriate separation distance for safe entry and exit of collecting, connecting, and collecting roads was examined. As a result of the analysis, it is found that a distance of 60m is required from the point where the merging starts. The results of this study are expected to contribute to the improvement of driver safety due to the conflict between entry and exit vehicles when applied to the weaving section where collecting roads are installed.
고속도로 위빙구간은 진입과 진출차량에 의한 상충이 발생되는 지점으로 본선과의 영향을 최소화하기 위하여 집산로를 설치토록 하고 있다. 집산로의 설계속도는 50km/h이나 실제 운전자는 설계속도에 맞춰 적정한 감속이 이루어지지 않고 있다. 따라서 본 연구에서는 운전행태, 설계기준차량제원, 운전자의 시야각등을 고려하여 차량의 안전한 진출입을 위해 고어 노면표시 끝에서 합류지점까지 적정 이격거리를 검토하였으며 분석결과 합류가능지점에서 약 60m의 이격거리가 필요한 것으로 분석되었다. 향후 본 연구결과를 집산로가 설치된 위빙구간에 적용시 진출입 차량간 상충으로 인한 운전자의 안전성 증진에 기여할 것으로 판단되며 집산로가 설치된 고속도로 위빙구간의 노면표시 설치기준으로 재정립 될 것으로 기대된다.
