To provide an intelligent roadside unit and a control method thereof having a high control capability at an intersection where traffic is extremely large.SOLUTION: An intelligent roadside unit includes: a traffic signal 110; a first camera 120 having a first focal length and acquiring a first image; a second camera 130 having a second focal length and acquiring a second image; and a controller 140 that obtains expected arrival traffic volume information on the basis of the first image, obtains current traffic volume information on the basis of the second image, and controls the traffic signal on the basis of the expected arrival traffic volume information and the current traffic volume information. The first focal length is greater than the second focal length. By installing two cameras having different focal lengths, the intelligent roadside unit obtains distant traffic and near traffic, and controls the traffic signal on the basis of both the expected arrival traffic volume information and the current traffic volume information, thereby controlling not only the current traffic volume but also the traffic signal on the basis of the expected traffic volume.SELECTED DRAWING: Figure 1

    【課題】交通量が極めて多い交差点で、制御能力が高いインテリジェント路側ユニット及びその制御方法を提供する。【解決手段】インテリジェント路側ユニットは、信号機110と、第1の焦点距離を有し第1の画像を取得する第1のカメラ120と、第2の焦点距離を有し第2の画像を取得する第2のカメラ130と、第1の画像に基づいて予想到着交通量情報を取得し、第2の画像に基づいて現在の交通量情報を取得し、予想到着交通量情報および現在の交通量情報に基づいて前記信号機を制御するコントローラ140と、を含む。第1の焦点距離は第2の焦点距離より大きい。焦点距離の異なる2つのカメラを設置することにより、遠方交通量および付近交通量を取得し、予想到着交通量情報および現在の交通量情報の両方に基づいて、信号機を制御し、現在の交通量だけでなく、予想された交通量にも基づいて信号機を制御する。【選択図】図1
