Outline of Final Research Achievements

This study aims to build up knowledge of the characteristics of the spatial search process based on the actual physical functions and brain activities that affect the physical behavior of elderly drivers when they pass through unsignalized intersections. Specifically, this study aims to obtain knowledge on (1) the relationship between physical functions and spatial search of elderly drivers and (2) the brain activities of elderly drivers when they pass through unsignalized intersections. Through the results of physical function, spatial search, and brain activity, it was confirmed that elderly drivers decrease their spatial search after entering an intersection, which increases in other age groups, especially at deformed intersections such as sharp corners, and that they are less aware of the importance of attention itself.

Academic Significance and Societal Importance of the Research Achievements

本成果により，今後の高齢運転者の無信号交差点における出会い頭事故対策を考える上で，特に注目すべき交差点形状や，通過時のポイントを特定できたと考える．これらの特徴を踏まえた高齢運転者に対する安全運転支援技術の開発や，GPSを利用した経路提供の開発は，一定程度有益であると考えられる．
