Abstract

Currently the IoT (Internet of Things) environments and related technologies are being developed rapidly through the networks for connecting many intelligent objects. The IoT is providing artificial intelligent services combined with context recognition based knowledge and communication methods between human and objects and objects to objects. With the help of IoT technology, many research works are being developed using the C-ITS (Cooperative Intelligent Transport System) which uses road infrastructure and traveling vehicles as traffic control infrastructures and resources for improving and increasing driver's convenience and safety through two way communication such as bus-only lane and license plate recognition and road accidents, works ahead reports, which are eventually for advancing traffic effectiveness. In this paper, a system for deciding whether the traveling vehicle is possible or not to drive on bus-only lane in highway is researched using the lane and number plate recognition on the road in C-ITS traffic infrastructure environments. The number plates of vehicles on the straight ahead and sides are identified after the location of bus-only lane is discovered through the lane recognition method. Research results and experimental outcomes are presented which are supposed to be used by traffic management infrastructure and controlling system in future.

최근 지능화된 사물들이 연결되는 네트워크를 통해 사람과 사물, 사물과 사물 간에 상호 소통하고 상황인식 기반의 지식이 결합되어 인공지능 서비스를 제공하는 사물인터넷 (IoT : Internet of Things) 환경이 급속도로 발전하고 있다. 이러한 사물인터넷의 발전과 더불어 C-ITS (Cooperative Intelligent Transport System) 환경에서 고속으로 이동하는 차량이 기존의 노변 인프라 외에 주행 중인 다른 차량까지 교통 인프라에 포함하여 차선 및 번호판 인식, 전방 사고 및 도로 공사 감지 등 쌍방향 정보 공유를 통해 효율적인 도로 주행을 함으로써 운전자에게 편리성과 안전성을 높여주고 나아가 교통 효율성을 높이고자 하는 연구가 활발히 진행되고 있다. 본 논문에서는 C-ITS 환경에서 고속도로 주행 시 버스전용 차선 인식 후 교통 인프라와 연계하여 버스전용 차선 내 주행차량의 주행 가능 여부를 판단하고 이에 따른 후속 조치에 관한 연구를 진행하였다. 버스전용차선 인식을 통해 버스전용 차로의 위치를 파악한 후 후속 차량의 정면 전방 및 측면 전방 차량의 번호판 인식을 진행하고 향후 교통 인프라로 하여금 인지하게 하는 방법에 관한 학습과 해당 실험결과를 제시하였다.
