Abstract

This paper investigates the intention to use shared autonomous vehicles in Brussels before and after an experience in virtual reality, in which a scenario of a city with shared autonomous vehicles was visualized taking into account transformations that are not possible to implement in real life such as urban form changes. 51 participants took part in a quasi-experiment and their acceptance of autonomous vehicles was measured before and after, using surveys based on the unified theory of acceptance and use of technology (UTAUT). Using partial least squares structural equation modeling, we model user acceptance pre- and post-VR experience and compare the change in influencing factors. Results show that, under the conditions we defined, the intention to use autonomous shuttles was influenced by the virtual reality experience, as there was an increase in the behavioral intention and a change in the significant predictors. Overall, we found evidence that the virtual reality experience did influence the acceptance of autonomous vehicles, and can then be an effective test bed to visualize future impacts of autonomous vehicles that are impossible to project in real life. Our study constitutes then a first step into exploring potential usages of virtual reality to project long-term visions of future developments of cities with shared autonomous vehicles.

探索虚拟现实体验对用户接受共享自动驾驶汽车的影响：布鲁塞尔准实验研究

本文调查了在虚拟现实体验前后布鲁塞尔使用共享自动驾驶汽车的意向，在虚拟现实中，共享自动驾驶汽车的城市场景被可视化，并考虑到了现实生活中不可能实现的转变，如城市形态的改变。51 名参与者参加了一项准实验，他们在实验前后对自动驾驶汽车的接受程度是通过基于技术接受和使用统一理论（UTAUT）的调查进行测量的。通过偏最小二乘结构方程模型，我们建立了用户接受自动驾驶汽车前后的模型，并比较了影响因素的变化。结果表明，在我们定义的条件下，自主班车的使用意向受到了虚拟现实体验的影响，因为行为意向增加了，重要的预测因素也发生了变化。总之，我们发现有证据表明，虚拟现实体验确实影响了人们对自动驾驶汽车的接受程度，因此可以作为一个有效的测试平台，将自动驾驶汽车未来的影响可视化，而这些影响在现实生活中是无法预测的。因此，我们的研究迈出了第一步，即探索利用虚拟现实技术预测未来共享自动驾驶汽车城市发展的长期愿景的可能性。

期刊介绍： Transportation Research Part F: Traffic Psychology and Behaviour focuses on the behavioural and psychological aspects of traffic and transport. The aim of the journal is to enhance theory development, improve the quality of empirical studies and to stimulate the application of research findings in practice. TRF provides a focus and a means of communication for the considerable amount of research activities that are now being carried out in this field. The journal provides a forum for transportation researchers, psychologists, ergonomists, engineers and policy-makers with an interest in traffic and transport psychology.
