신신호시스템(COSMOS)의 일반국도 적용에 대한 연구
A study of signal control with COSMOS on National Highway
Abstract
The performance of the National Highway is raised, but the capacity of the signalized intersection on the National Highway is low. It's operated by TOD(Time Of Day) mode. To evaluate of the performance of COSMOS(Cycle, Offset, Split Model for Seoul), a real time traffic adaptive signal control system, on the National Highway, studied volume, travel time and queuing length at TOD control and TRC(Traffic responsive Control). Consequently, the average travel speed at TRC is high 2.9~16.7km/h then the average travel speed at TOD control. And te queuing length at TRC is low 15~196m then the queuing length at TOD control.
