Abstract

A national highway takes on an arterial roadway role between regions. It's traffic volume of minor approach is very lower than mainline because most of the traffic of national highway consists of through traffic. This means an actuated signal operation is more efficient on the national highway than pre-timed signal. actuated signals have detections on some or all movements except the mainline. In spite of these effects have been evaluated in previous studies, widespread propagation of actuated signal operation has not made so much in Korea. Because there are so many problems to use actuated signal as it is in side of roadway facilities. In this study, improved a actuation system for the national highway and evaluated it with field implementation.

일반국도는 지역과 지역을 연결하는 간선도로 역할을 하는 도로이다. 일반국도는 통과교통 비중이 높아 약 90% 이상이 직진교통량이며, 좌회전 및 부도로의 교통량은 직진교통량에 비해 매우 낮다. 이러한 도로의 특성을 고려해 볼 때, 고정식제어보다는 감응제어가 더 효과적이다. 이와 같은 감응제어의 효과가 과거 많은 논문에서 검증되었음에도 우리나라의 경우 일부 도시구간에서 극히 한정적으로 사용하고 있을 뿐 본격적인 설치가 전혀 이루어지지 않았다. 그것은 우리나라의 국도 시설 특성 상 감응제어를 교과서적으로 운영하기 어려운 요소가 많다는 데에 있다. 본 연구에서는 감응제어 도입이 어려운 이유를 파악하여 우리나라 현실에 맞도록 개선하였으며, 시범운영을 통해 국도 감응제어시스템의 효과를 입증하였다.
