Outline of Final Research Achievements

In this study, we focused on unsignalized intersections where a systematic solution is not yet found due to the diversity of traffic environment. Among this traffic space, we clarified individual differences in basic cognitive abilities of elderly drivers, and behavioral requirements to drive safely in the traffic space from driving behavior of instructors. Moreover, we classified unsafe behaviors at unsignalized intersections according to the difference in speed transition, and found that those behaviors are related to speed anticipation characteristics of the elderly. In addition, we regarded this unsafe behavior as errors due to errors in situational judgment or operational behavior selection of the elderly at unsignalized intersections, and showed that unsafe driving behavior of the elderly can be complemented by enabling them to grasp their own behavior objectively and understand safe and sufficient behavior.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は,運転と関連する認知能力の個人差に加え,その交通環境の多様性から体系的な解決が見いだせていない人間機械協調系における運転行動を逆強化学習を用いることにより数理化を可能とし,得られた数理モデルから高齢者が持つヒューマンエラーの要因抽出に繋がり,本研究の手法とその知見は学術的意義が高い.また,得られた知見は,既存の社会システムにおける高齢者の移動問題の観点から,高齢者の自立生活の促進,安全性を確保することにつながり,社会的意義が高い研究である.
