<p>This research aims to show how driving with Level 2 automation affects situational awareness. The experiment participants drove on an expressway in a Level 2 automated vehicle and in a non-automated vehicle for 30 [min] for each vehicle. Fifteen middle-aged drivers and 15 elderly drivers participated. The experimental vehicle was a 2016 Nissan Serena equipped with an SAE Level 2 automated driving system. In all runs, the most common cause of override was vehicles merging from on-ramps. In situational awareness determined from video recordings of the driver’s gaze, the situational awareness of the elderly drivers might decrease while automated driving.In a subjective survey, the middle-aged drivers reported difficulty in maintaining situational awareness during automated driving. To prevent accidents at on-rampsdue to situational awareness reductions, the road and the automated vehicle system must be improved to mitigate losses in situational awareness.</p>
