Abstract

Roundabouts are actively installed to reduce unnecessary congestion and reduce traffic accidents. However, it is difficult to apply more than 450 cars per, hour. In addition, there is a downside to the concentration of delays in certain directions depending on traffic conditions. To compensate for these shortcomings, signal metering was introduced. Signal metering is a technique that gives red signals to adjacent left traffic flow in the event of a delay in a particular direction. The purpose of this study is comparing the effect of signal metering in conventional and special types (turbo roundabout, flower roundabout) of roundabout. VISSIM API is used for analysis. The analysis result show that only conventional roundabout signal metering algorithm reduce delay time per vehicle. As the result of the turbo roundabout and flower roundabout signal metering algorithm increase delay time per vehicle, signal metering algorithm can be applied in conventional roundabout.

회전교차로는 불필요한 정체를 줄이고 교통사고를 감소시키기 위하여 적극적으로 설치되고 있다. 하지만 차로당 교통량이 450대 이상인 경우 도입이 어렵고 교통여건에 따라 특정방향에 지체가 집중될 수 있는 단점이 존재한다. 이러한 단점을 보완하기 위해 회전교차로에 신호미터링을 도입하였다. 신호미터링은 특정방향에 지체가 발생한 경우 인접한 진입 교통류에 적색신호를 부여하여 지체가 발생한 방향의 회전교차로 진입을 원활히하는 기법이다. 본 연구에서는 기존 일반 회전교차로와 특수유형 회전교차로인 Turbo형 회전교차로와 Flower형 회전교차로를 대상으로 신호미터링을 도입하여 회전교차로 유형별 신호미터링 도입 효과를 비교 분석하였다. 분석에는 VISSIM API를 이용하였으며, 분석결과 기존 회전교차로의 경우에만 신호미터링 알고리즘 도입 시 지체감소 효과를 보였다. Turbo형, Flower형 회전교차로의 경우 지체가 증가하는 것으로 나타나 기존 회전교차로의 경우에 신호미터링 알고리즘 도입 시 효율적인 교차로 운영이 가능한 것으로 분석되었다.
