ABSTRACT

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.

摘要

尽管无人驾驶汽车（AV）已被证明具有减少交通事故的潜力，但人们经常对自动驾驶汽车的安全性持怀疑态度。关键问题在于，是什么促使人们感知和期望AV的安全性。在本文中，构建了一个结构模型，包括风险敏感性，与风险相关的感觉，感知的和预期的安全性。对185名受访者进行了调查，并使用PLS-SEM分析了结果。我们的研究通过探索风险敏感性和感觉如何解释AV的安全性判断并建立它们之间的联系，对AV的安全性判断的心理原因提供了更深刻的理解。结果发现，感知安全感比恐惧感更受担忧之感的影响，但是感知安全感与预期安全感之间没有显着相关性。
