Analysis of the driving behavior when the system safety level during automated driving is presented to drivers

In this study, it was analyzed how presenting information on the system safety level of automated driving system affects the driving behavior of driver, with the experiment using the driving simulator. During automated driving categorized to the level 2, we analyzed the driving preparation level of...
