Abstract

The domestic road space is reaching the limit of planar space distribution, and Increasingly, the importance of three-dimensional space distribution through the development of underground space. therefore, In this study, a study was conducted on a traffic control method that can safely induce two different traffic flows in the connection between the ground road and the underground road. Through VISSIM, we calculated the appropriate amount of outflow and inflow traffic compared to the capacity of the main line when there is a Merge/Diverge section in the underground road. and Through the analysis of the number of conflicts, the appropriate traffic control level for safety in the underground, A basic study was conducted on the level of risk in the underpass according to the level of delay in the ground part through the analysis of the delay scenario of the ground road.

국내 도로공간은 평면적 공간 분배의 한계점에 다다르고 있으며, 점점 지하공간의 개발을 통한 입체적 공간 분배의 중요성이 대두되고 있다. 이에 본 연구에서는 지상도로와 지하도로의 연계에 있어 서로 다른 두 교통흐름을 안전하게 유도할 수 있는 교통제어 방안에 대한 연구를 수행하였다. VISSIM을 통해 지하도로 내 분·합류부가 존재할 경우의 본선 용량대비 적정 유출·입 교통량을 산출하였으며, 상충 수 분석을 통해 지하도로 내 안전을 위한 적정 교통량 제어수준을 분석하였고, 지상도로의 지·정체 시나리오 분석을 통해 지상부 지·정체 수준에 따른 지하도로 내 위험도 수준에 대한 기초연구를 수행하였다.
