PROBLEM TO BE SOLVED: To detect un-actualized traffic obstruction action of another vehicle in advance to make a control object vehicle execute a risk reduction action for the un-actualized traffic obstruction action.SOLUTION: A drive support device (3) extracts (31) information on a traffic obstruction action of another vehicle in the past based on acquired drive history of the other vehicle to set (32) risk of the other vehicle from extracted information on the traffic obstruction action. Then, the drive support device determines (34) a risk reduction action of a control object vehicle (2) using the set risk, information on the position of the control object vehicle, and information on the position of the other vehicle to generate (35) a risk reduction control signal for making the control object vehicle execute the determined risk reduction action.SELECTED DRAWING: Figure 1 【課題】他車両の顕在化していない交通阻害行動を事前に検知して、この顕在化していない交通阻害行動に対しても、リスク低減行動を実行させる。【解決手段】運転支援装置（３）は、取得した他車両の運転履歴に基づき、過去の他車両の交通阻害行動に関する情報を抽出し（３１）、抽出した交通阻害行動に関する情報から他車両のリスクを設定する（３２）。そして、運転支援装置は、設定されたリスクと、制御対象車両の位置に関する情報と、他車両の位置に関する情報とを用いて、制御対象車両（２）のリスク低減行動を決定し（３４）、決定したリスク低減行動を制御対象車両に行わせるためのリスク低減制御信号を生成する（３５）。【選択図】図１
