AI总结：
本研究采用VR技术模拟无标线多车道穿越场景中的AV行为与信号指示，发现沉浸式体验显著提升了行人对AV的态度与系统有效性信任，且黄色信号和积极穿越行为对感知改变有重要影响。
摘要：
阻碍行人对自动驾驶车辆（AVs）广泛接受的主要障碍之一是他们对AVs的理解有限。本研究采用虚拟现实（VR）技术，为行人提供一个沉浸式环境，使其在无标线路段多车道穿越期间能够与AVs互动并理解AVs。研究模拟了多种AV驾驶行为，包括带有黄色信号指示的协商让行行为，以及带有蓝色信号指示的不让行行为。本文旨在调查AV行为与信号指示、行人过往行为等各种因素对行人AV感知变化的影响。在VR实验前后，参与者完成了评估其AV感知的调查，重点关注“态度”和“系统有效性”两个主要方面。Wilcoxon符号秩检验结果表明，VR实验后，行人对AVs的总体态度得分以及对AV系统有效性的信任度均显著提高。值得注意的是，对黄色信号表现出更高信任度的个体，更倾向于对AVs表现出更高的态度得分，并增强其对AV系统有效性的信任。这表明黄色信号的设计使行人在与AVs互动时更有信心。此外，与表现出更积极穿越行为的行人相比，表现出更具攻击性穿越行为的行人改变其对AVs感知的可能性较小。结论是，在沉浸式VR环境中整合本文设计的AV行为与信号指示，促进了行人与AVs的互动，从而改变了他们对AVs的感知。
英文摘要：
One of the primary impediments hindering the widespread acceptance of autonomous vehicles (AVs) among pedestrians is their limited comprehension of AVs. This study employs virtual reality (VR) to provide pedestrians with an immersive environment for engaging with and comprehending AVs during unmarked midblock multilane crossings. Diverse AV driving behaviors were modeled to exhibit negotiation behavior with a yellow signal indication or non-yielding behavior with a blue signal indication. This paper aims to investigate the impact of various factors, such as AV behavior and signaling, pedestrian past behavior, etc., on pedestrians' perception change of AVs. Before and after the VR experiment, participants completed surveys assessing their perception of AVs, focusing on two main aspects: "Attitude" and "System Effectiveness." The Wilcoxon signed-rank test results demonstrated that both pedestrians' overall attitude score toward AVs and trust in the effectiveness of AV systems significantly increased following the VR experiment. Notably, individuals who exhibited a greater trust in the yellow signals were more inclined to display a higher attitude score toward AVs and to augment their trust in the effectiveness of AV systems. This indicates that the design of the yellow signal instills pedestrians with greater confidence in their interactions with AVs. Further, pedestrians who exhibit more aggressive crossing behavior are less likely to change their perception towards AVs as compared to those pedestrians with more positive crossing behaviors. It is concluded that integrating this paper's devised AV behavior and signaling within an immersive VR setting facilitated pedestrian engagement with AVs, thereby changing their perception of AVs.
