Driver Confidence and Level of Automation Influencing Trust in Automated Driving Features

Abstract

The goal of this study was to empirically examine the relationship between individuals’ reported trust in automated driving features and their level of self-confidence when driving. This study utilized a series of vignettes to depict three different levels of automation in accordance with the SAE International levels of Automation. The three levels portrayed low (level 1), moderate (level3), and high (level 5) functioning autonomous driving features. A driving self-efficacy scale and trust in automation scale were utilized to collect data about individuals attitudes towards the automation. It was hypothesized that self-confidence and level of automation would be significantly related to operator’s trust. In addition to this, it was also hypothesized that the level of automation would significantly affect the amount of trust placed in the autonomous features. Results indicated that there are significant relationships between self-confidence and trust, as well as level of automation and trust.

Assessing How Driving Self-Efficacy Influences Situational Trust in Driver Assist Technologies

“…The scenario complexity did still impact trust, despite the presence of the covariate. Trust tended to be higher with lower levels of automation in the driving feature, consistent with previous findings (Miele et al, 2021).…”

“…Automation tends to be used more frequently in situations where the operator is not as confident in themselves (De Vrise et al, 2003). Drivers' confidence has been shown to be related to trust in driver assist features at lower levels of automation (Miele et al, 2021). Research is still needed to confirm how automation related features, such as level of automation, might interact with environmental factors to influence trust.…”

Implicit theories in driving: Scale development, validation, and predictive role on violations and driving self-efficacy

“…In order to test these general hypotheses more specifically, we selected variables frequently used in the driving literature: driving self-efficacy, violations, accidents, and emergency maneuvers. Indeed, self-efficacy is a variable often used to study psychological profiles in driving (Miele et al, 2021;Zhang et al, 2020). Violations are measured with the Driving Behaviour Questionnaire (DBQ), which has been used extensively in the field of driving (de Winter and Dodou (2010) reported 174 studies using this questionnaire).…”
