Although autonomous vehicles (AVs) have been proved to have potential to reduce traffic accidents, people often hold skepticism toward the safety of AVs. The critical question is that what drives people to perceive and expect the safety of AVs. In this paper, a structural model is constructed, comprising risk sensitivity, risk-related feelings, perceived and expected safety. A survey of 185 respondents was conducted, and the results were analyzed by using PLS-SEM. Our study provided a deeper understanding of mental reasons for safety judgments in AVs by exploring how risk sensitivity and feelings explain safety judgment in AVs and establish the connections between them. It is found that perceived safety was influenced by feelings of worry more than dread, but there was no significant correlation between perceived safety and expected safety. New possible research ideas of AV's safety study are discussed in the paper.
