Abstract

Highlights: Drivers' trust increase during the first interactions with simulated automated driving. Initial level of trust impact early trust construction. Trustful drivers engage more in non-driving related activities. Trustful drivers monitor less the driving environment. Critical situations may temporarily decrease driver's trust. Abstract: Trust in Automation is known to influence human-automation interaction and user behaviour. In the Automated Driving (AD) context, studies showed the impact of drivers' Trust in Automated Driving (TiAD), and linked it with, e.g., difference in environment monitoring or driver's behaviour. This study investigated the influence of driver's initial level of TiAD on driver's behaviour and early trust construction during Highly Automated Driving (HAD). Forty drivers participated in a driving simulator study. Based on a trust questionnaire, participants were divided in two groups according to their initial level of TiAD: high (Trustful) vs. low (Distrustful). Declared level of trust, gaze behaviour and Non-Driving-Related Activities (NDRA) engagement were compared between the two groups over time. Results showed that Trustful drivers engaged more in NDRA and spent less time monitoring the road compared to Distrustful drivers. However, an increase in trust was observed in both groups. These results suggest that initial level of TiAD impact drivers' behaviour and further trust evolution.
