Abstract

Reversible lanes in urban intersections is used to efficiently control vehicles, reduce traffic congestion and increase the capacity of a roadway. But by far traffic control systems in urban intersections are simple and manually operated by police officers. In this study, we present a hybrid algorithm that intelligently resolve the moving direction of reversible lanes to efficiently manage the flow of traffic at intersection. The proposed algorithm consists of three stages:(i) fuzzy inference method to get the efficiency of moving direction, (ii) a provisional decision whether to change the reversible lane to different direction, (iii) a final evaluation criterion for changing the directions of the reversible lanes. The fuzzy inference results of efficiency are shown by using matlab application.

교차로에서 가변차선은 이동하는 차량들을 효율적으로 통제하고 교통 혼잡을 줄일 수 있으며 도로의 가용 능력을 증가시키기 위한 도구로 사용되고 있다. 그러나 아직까지 가변차선의 교통통제는 단순하며 수동으로 가변차로를 운용하고 있다. 따라서, 본 연구에서는 가변차로의 이동방향에 대한 변경 여부를 지능적으로 판단하여 교통 흐름을 효율적으로 개선하기 위한 3단계 방법을 제안한다. 첫 번째는 교차로에서 차량이 이동하는 방향으로 효율성을 판단하기 위한 방법으로 퍼지추론 방법, 두 번째는 이동방향으로 가변차로를 변경할 지에 대한 잠정 판단, 세 번째는 이러한 잠정판단을 최종결정하기 위한 판단기준을 제시한다. 이동방향으로의 효율성은 matlab 프로그램을 이용하여 얻는다.
