Self-driving cars are expected to be integrated into the traffic system in the near future. It is crucial to understand how the public accepts self-driving cars and how adoption rates are influenced. The main purpose of this study was to investigate how trait anxiety and the Big Five personality traits affect acceptance and to provide a personality profile of early adopters of self-driving cars. A total of 527 drivers participated in the research, completing Chinese versions of the Self-driving Car Acceptance Scale, the Trait Anxiety Inventory, and the Big Five Inventory and some demographic questions. The results showed that trait anxiety had a positive effect on perceived automation reliability. Openness and extraversion had positive effects on self-driving car acceptance, while neuroticism had a negative effect. People with high agreeableness had a more positive perspective on the benefits of self-driving cars, but they were also more worried about ease of use and automation reliability. These results help to provide a personality profile of early adopters of self-driving cars. People with certain personality traits are more likely to be starting points for the diffusion of self-driving cars.

特质焦虑和大五人格特质对自动驾驶汽车接受度的影响

无人驾驶汽车有望在不久的将来融入交通系统。了解公众如何接受自动驾驶汽车以及如何影响采用率至关重要。本研究的主要目的是调查焦虑特质和大五人格特质如何影响接受度，并提供自动驾驶汽车早期采用者的个性特征。共有 527 名司机参与了研究，完成了中文版的自动驾驶汽车接受量表、特质焦虑量表、大五量表和一些人口统计问题。结果表明，特质焦虑对感知自动化可靠性有积极影响。开放性和外向性对自动驾驶汽车的接受度有积极影响，而神经质有消极影响。亲和度高的人对自动驾驶汽车的好处有更积极的看法，但他们也更担心易用性和自动化可靠性。这些结果有助于提供自动驾驶汽车早期采用者的个性特征。具有某些个性特征的人更有可能成为自动驾驶汽车普及的起点。
