PROBLEM TO BE SOLVED: To provide a drive aptitude diagnosis apparatus for securely diagnosing a drive aptitude.SOLUTION: A drive aptitude diagnosis apparatus comprises: a monitor 114 an operation switch 115 storage means 100 for storing a program 101 and control means 104 for executing the program 101. By executing the program 101, the control means 104 implements: means 105 for displaying a moving object and a boundary line on a monitor means 106 for setting a moving object to be selected means 107 for controlling a motion of the moving object means for determining type agreement of the moving object when a subject pushes down a switch means for determining that a result of the pushing is incorrect when the type agreement is not satisfied means for determining whether or not a moving object exists on the boundary line means for determining that a result is a correct one when the moving object is on the boundary line, determining that the result is a first incorrect one when the moving object is not on the boundary line and has not crossed the boundary line, and determining that the result is a second incorrect one when the moving object is not on the boundary line and has crossed the boundary line means for performing determination depending on a position of the moving object with respect to the boundary line when the result is correct and diagnosis means 113 for diagnosing the subjects accident possibility from the results of the first determination means 110 to the third determination means 112 and correlation between existing results and accidents.COPYRIGHT: (C)2016,JPO&INPIT【課題】運転適性を確実に診断する運転適性診断装置の提供。【解決手段】モニタ114と、操作スイッチ115と、プログラム101を記憶する記憶手段100と、プログラム101を実行する制御手段104を備え、制御手段104がプログラム101の実行で実現する手段として、移動物体と境界線をモニタに表示手段105と、選択移動物体を設定手段106と、移動物体の動き制御手段と107、被験者のスイッチ押下時、移動物体の種類一致を判断する手段と、相違の場合不正解と判定する手段と、移動物体の境界線上の有無を判断する手段と、境界線上にあれば正解、ない場合、境界線手前は第一不正解、通過は第二不正解と判定する手段と、正解の場合、移動物体の境界線に対する位置に応じた判定を行う手段と、第一判定手段110乃至第三判定手段112の結果と、既存結果と事故との相関から被験者の事故可能性を診断手段113を有する運転適性診断
