Abstract

After installing roundabouts, changes of travel behaviour in the vicinity of roundabouts can cause increasing traffic volumes and unbalanced flow conditions. In that cases, the efficiency of roundabouts as a whole intersections can drop due to the insufficient gap between vehicles in the circulating lanes. The purpose of this study is developing a dynamic signal metering operation method for roundabouts in which a real time Signal Metering operation algorithm is suggested and its performance is tested by using VISSIM COM Interface(Visual Basic Application). The results of the real time Signal Metering operation show that there is a substantial delay improvements when two adjoined approaches are combined together and the flows of metering approach are less than controlling approach. Especially, the total entering flow is around 1,600 vehicle/h gives the delay reduction per vehicle of 70.9~102.2(73.8~77.8%) seconds for four-lane-approach with one-lane roundabouts.

회전교차로(roundabouts) 설치이후 주변의 통행행태 변화로 인한 교통량 증가로 접근로별 교통류가 불균등(unbalanced flows) 해질 경우 접근로에서 회전교차로 내부로의 진입이 어려워져 교차로 전체의 효율성이 떨어지게 된다. 본 연구에서는 회전교차로 본래의 기능을 최대한 유지하면서 운영효율성을 높이기 위한 신호미터링 운영방안으로 동적 신호미터링 운영알고리즘을 제시하였고, 효과분석은 VISSIM의 COM Interface(Visual Basic Application) 기능을 활용하였다. 본 연구결과 인접한 두 진입로를 한 쌍(pair)으로 묶고 미터링진입로의 교통량이 통제진입로의 교통량 보다 작은 경우 실시간 Signal Metering운영 효과가 높은 것으로 분석되었다. 특히, 1차로형 4지 회전교차로를 기준으로 총 진입교통량이 1,600대/시일 때 차량 당 평균지체가 70.9~102.2초/대로 73.8~77.8% 감소하는 것으로 분석되었다.
