Abstract

<p><tt>超高齢社会である日本では,高齢者の日常の外出手段となる公共交通を今後も維持することが重要な社会課題となっている.一方で,高齢化の進展に伴い,バス運転手の高齢化も進んでいる.一般の高齢運転者は,一度に確認すべき対象が多数存在する場面において安全確認回数が有意に少なくなる傾向にあることが先行研究で指摘されている.しかしながら高齢者がバス運転時にどのような運転行動を示すのか把握しようとした研究例は稀少である.本研究では,高齢バス運転手のバス運転時の視線を計測し,先行研究で計測した新人運転手,指導運転手の視線データとの比較を行った.その結果,同時に複数の注視対象物を確認すべき状況において,事故リスクを低減するために確認すべき対象物への注視回数が,高齢運転手は有意に少ないことが明らかとなった.</tt></p>

<p>Since Japan is a super aging society, maintaining safe public transportation service is an important issue. Nevertheless, the number of elderly bus drivers is increasing as rapid aging of the population continues. Our previous study showed that elderly drivers tended to perform less scanning behavior than non-elderlies where driver should simultaneously pay attention to multiple hazards around the vehicle. However, few studies have investigated to understand characteristics of elderly bus drivers' behavior. In this study, we measured elderly bus drivers gaze behavior while driving in real traffic conditions, and compared the measured data to those of non-elderly bus drivers (drivers in training and bus instructors). As a result of our analysis, we found out that elderly bus drivers performed significantly less checking behavior than even drivers in training in traffic scenes frequently occurred in a daily service, especially traffic scenes where driver should simultaneously pay attention to multiple mirrors and traffics around to prevent accidents.</p>
