Outline of Final Research Achievements

We conducted a study to understand the skills retained and declined by inactive drivers when they resume driving. To do so, we enlisted university students with minimal driving experience post-licensing and compared their performance on driving tasks with those about to obtain their licenses. The results confirmed a decline in skills among the former group.

Additionally, we aimed to identify habits associated with aggressive driving and explore the psychological factors contributing to such behavior. Through a web survey, we found that individuals with grandiose narcissism, characterized by arrogance and high confidence, tend to display direct aggressive behavior. Conversely, those with vulnerable narcissism, marked by low self-esteem and sensitivity to criticism, are more prone to perceiving malicious intent and anger while driving, indirectly leading to aggressive behavior.

Academic Significance and Societal Importance of the Research Achievements

本研究では、運転中の悪癖を抽出し、ドライバー自身に認識させるための教育開発を目指した。ドライバーの何気ない悪癖を把握しておくことは、自動運転車と手動運転車の混在する期間において、両者のインタラクションを円滑にするための基礎データになる可能性を秘めている。
また社会的関心を集める「あおり運転」に対しても、その生起過程の一部を明らかにすることができ、啓発活動の根拠となるデータを取得した。
