Zusammenfassung:Provided are a device and a method for operating a variable traffic safety sign in accordance with a traffic condition of access roads at a non-signalized intersection. According to the present invention, an object recognition unit recognizes moving objects accessing a non-signalized intersection from videos obtained by photographing access roads of an intersection (hereinafter, referred to as "a non-signalized intersection") which is not controlled by a traffic light. With respect to any one (hereinafter, referred to as "target object") of the recognized moving objects, a variable sign control unit variably displays a traffic safety sign of a traffic safety sign installation/management manual of the national police agency on the basis of a road condition including the moving object positioned at the remaining access roads other than an access road where a target object is positioned, and controls a variable traffic safety sign device to variably display a guidance phrase which recommends to obey content of the variably displayed traffic safety sign. In addition, the variable traffic safety sign device is provided to variably display a traffic safety sign and a guidance phrase in accordance with a road condition by control of the variable display control unit, and to allow the target object to be directed thereto. Therefore, a traffic accident can be prevented. 비신호교차로에서 접근로들의 교통상황에 따른 가변 교통안전표지 운영장치 및 방법이 제공된다. 객체 인식부는 교통신호등에 의해서 제어되지 않는 교차도로(이하, '비신호교차로'라 한다)의 접근로들을 촬영한 동영상들로부터 비신호교차로로 접근 중인 이동객체들을 인식하고, 가변 표지 제어부는 인식된 이동객체들 중 어느 하나(이하, '타겟 객체'라 한다)에 대하여, 타겟 객체가 위치한 접근로 외의 나머지 접근로들에 위치하는 이동객체를 포함하는 도로상황에 기반하여 경찰청 교통안전표지 설치/관리 매뉴얼 상의 교통안전표지를 가변적으로 표시하고, 가변적으로 표시되는 교통안전표지의 내용을 준수하도록 권고하는 유도 안내 문구를 가변적으로 표시하도록 가변 교통안전표지 장치를 제어하며, 가변 교통안전표지 장치는, 가변 표지 제어부의 제어에 의해, 교통안전표지와 유도 안내 문구를 도로상황에 따라 가변적으로 표시하며, 상기 타겟 객체가 바라보도록 구비된다.
