| Outline of Final Research Achievements |
A comparison test of a simulated driving test was conducted using an automobile driving cognitive behavior evaluation device (this device) and HONDA Safety Navigation System (control device). Palmar sweating responses and prefrontal oxy-Hb responses corresponding to danger, safety, and danger prediction were generally consistent across multiple comparison tests, confirming the reliability and validity of the simulated driving test using this device to evaluate the functions of danger perception and danger prediction. The group that admitted accidents with the control device showed less palmar sweating response in the simulated driving test, which was considered to be a finding indicating insufficient risk perception. In the simulated driving test using the control device, subjects tended to show greater subjective tension, palmar sweating, and prefrontal oxy-Hb responses, which were thought to be caused by the unfamiliar virtual wide-angle computer graphic (CG) images.

本装置による模擬運転テストでは被験者の危険認知を手掌部発汗，危険予測を前頭前野oxy-Hbによって評価する点が最大の特徴であり，ハンドル，アクセル，ブレーキの操作反応を視覚化し，映像と照らした振り返りができるメリットがある．本装置では実写の運転映像を用いるため，多数サンプルによる標準反応を得ることで，場面に応じた個々の応答特性が評価できる．また，被験者の生活圏域を走行する映像が入手できれば，より具体的な危険認知の予行演習が可能であり，本装置による模擬運転テストの優位性と言える．今後，ウェアラブル計測装置によるデータ収集方法が確立できれば，実車運転時の危険認知評価への応用が期待できる．
