How the initial level of trust in automated driving impacts drivers’ behaviour and early trust construction

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