Abstract
This paper describes about non-burial AVI (Automatic Vehicle Identification) system using general vehicle as probe car for obtaining more accurate traffic information while conserving road pavement surface. Existing spot traffic detectors have their own limits of not obtaining right information owing to its mathematical method. Burial AVI systems have some defects, causing traffic jam, needing much maintenance cost because of frequent cutting of loop and piezo-electric sensors. Especially, they have hard time to make right detection, when it comes to jamming time. Therefore, in this paper, we propose non-burial AVI system with laser trigger unit. Proposed non-burial AVI system is developed to obtain regional traffic information from normal Passing vehicle by automatic license number recognition technology. We have adapted it to national highway section between Suwon city and Pyong
본 연구는 기존 지점검지기와 비콘검지기 및 매설식 자동차량인식장치(Automatic Vehicle Identification : AVI)의 한계점을 극복하고자 비매설식 AVI를 개발하고 이를 통하여 도로상을 주행하는 일반적인 차량들을 프루브 차량으로 활용하여 신뢰성 있는 구간교통정보를 산출하는 방법을 개발하는 것을 목적으로 한다. 이를 위해 비매설식 자동차량인식장치를 개발하고, 국도1호선 수원
