PROBLEM TO BE SOLVED: To provide a technique for providing a guide with a timing at which a vehicle can be stopped before reaching a sudden deceleration cause, without excessively decelerating.SOLUTION: An operation aiding system comprises: travel history acquisition means for acquiring the travel histories of a plurality of vehicles; traveling history analysis means for acquiring, on the basis of the travel histories of the vehicles that have suddenly decelerated due to the identical sudden deceleration cause, a sudden deceleration point at which sudden deceleration took place and an initial vehicle speed, which is the speed of the vehicle at the sudden deceleration point; vehicle speed transition acquisition means for acquiring a vehicle speed transition for stopping the vehicle on this side from any point at which the vehicle is stopped when the vehicle is decelerated at a predetermined deceleration speed from the initial vehicle speed at each sudden deceleration point; and guide means for guiding in order to call an attention to a vehicle approaching the sudden deceleration cause at a vehicle speed exceeding the vehicle speed transition.
【課題】過度の減速を行うことなく急減速原因に到達する前に停止させることが可能なタイミングで案内を行う技術の提供。【解決手段】複数の車両の走行履歴を取得する走行履歴取得手段と、同一の急減速原因によって急減速が行われた複数の前記車両についての前記走行履歴に基づいて、急減速された地点である急減速地点と当該急減速地点での前記車両の車速である初期車速を取得する走行履歴解析手段と、各急減速地点において前記初期車速から所定の減速度で前記車両を減速させた場合に前記車両が停止するどの地点よりも手前で前記車両を停止させるための車速推移を取得する車速推移取得手段と、前記車速推移を超える車速で前記急減速原因に接近する車両に走行の注意を促す案内を行う案内手段と、を備える運転支援システムを構成する。【選択図】図3
