매설형 검지기는 검지 성능이 타 검지기에 비해 우수하지만, 설치 및 관리비용이 클 뿐 아니라 도로의 재포장이나 도로파손으로 인해 수명이 짧다는 단점이 있다. 이에 반해 기존 지주에 부착하여 사용하는 검지시스템인 비매설형검지기는 도로 노면을 손상시키지 않기 때문에 설치가 쉽고, 유지관리비용이 적다는 장점이 있다. 비매설식 검지기는 이러한 장점에도 불구하고, 검지 성능이 낮아 아직까지 신호제어용으로 사용하지 못하는 실정이다. 본 연구에서는 비매설형 검지기 중에 정확도가 가장 높은 FMCW 방식의 레이더에 대해 성능평가를 수행하고, 신호제어용 검지용도별로 현장적용 유/무 결과를 제시하였다.
Abstract
Intrusive Vehicle Detectors have excellent detection performance compared to other types of detector, but disadvantages of high installation and maintenance costs, short life time due to greater damage to roads and paving materials. In contrast, Non-Intrusive Vehicle Detectors attached to the stationary pole have advantages because it does not damage the road surface and easy and less expensive to maintain. Despite these advantages, Non-Intrusive type detectors are still not been widely used in traffic signal control systems because of the low detection performance. In this study, a FMCW(Frequency Modulated Continuous Wave) radar Vehicle Detector was designed as an alternative detector for the signalized intersection, and the performance evaluation was presented by purpose applicability.
