Observation and Consideration of Driver Behavior on Autonomous Driving

Abstract

In the revised road traffic law, drivers are allowed to engage in non-driving-related behaviors, such as reading books and operating smartphones, while using the Society of Automotive Engineers (SAE) level 3 autonomous driving. However, previous research shows that drivers over-rely on autonomous driving. The safety of SAE level 3 autonomous driving will be in question if it allows drivers behaviors unrelated to driving. Therefore, we observed drivers’ behavior on autonomous driving using a driving simulator and consider the tendency of behavior. The results show that most drivers become sleepy with time and operate their smartphones because they become bored during autonomous driving. キーワード：自動運転，ドライバ行動，ドライビングシミュレータ
