To generate practical road traffic information.SOLUTION: A road traffic information generation device includes at least a probe information acquisition section, a winker information processing section, and a horizontal direction analysis section. The probe information acquisition section acquires probe information including winker information related to a winker operation of a vehicle at each predetermined time for each travel direction and for each link being a zone obtained by dividing a road in a longitudinal direction. When the number of winker operations in the same direction indicated by the winker information in the link is equal to or more than a first predetermined value, the winker information processing section adds the number of the winker operations in the same direction indicated by the winker information in the links on an upstream side of the pre-fixed number so as to allow the number to be a movement total sum of the link. In the other case, the number of the winker operations in the same direction of the link is allowed to be the movement total sum. When an absolute value of a difference between the movement total sums in the right direction and the left direction of the link is greater than a second predetermined value, the horizontal direction analysis section determines a horizontal direction abnormality in the direction with the less movement total sum.SELECTED DRAWING: Figure 1

    【課題】より実用的な道路交通情報を生成する。【解決手段】本発明の道路交通情報生成装置は、少なくともプローブ情報取得部、ウインカー情報加工部、横方向分析部を備える。プローブ情報取得部は、進行方向ごとに、道路を長さ方向に区切った区間であるリンクごとに、所定時間ごとの車両のウインカーに関するウインカー情報を含むプローブ情報を取得する。ウインカー情報加工部は、リンクにおけるウインカー情報が示す同じ方向のウインカーの数が第1所定値以上の場合に、あらかじめ定めた数の上流側のリンクにおけるウインカー情報が示す同じ方向のウインカーの数を加算して当該リンクの移動合計とし、それ以外の場合は当該リンクの同じ方向のウインカーの数を移動合計とする。横方向分析部は、リンクの右方向と左方向の移動合計の差の絶対値が第2所定値より大きい場合に、移動合計が少ない方向の横方向異常と判断する。【選択図】図1
