随着头戴式显示技术的最新进展，虚拟现实行人模拟器已成为交通安全研究的常用工具。与现场研究、测试跑道研究和交通观察相比，模拟器使研究人员能够在安全和受控的环境中分析行人的行为。然而，创建必要的虚拟环境非常耗时，特别是在满足当今对图形细节和真实感的期望方面。此外，VR 实验通常缺乏身体表征或需要额外的传感器来创建化身。由于实验室环境的原因，VR 模拟器可能无法传达站在真实街道上的感觉。此外，一方面是模拟器，另一方面是现实世界的测试，在现实与虚拟的连续体上留下了方法上的差距。本文提出了一种增强现实行人模拟器的新颖方法。通过该模拟器，参与者可以体验虚拟车辆，并在真实场景中进行增强，从而可以在现实环境中进行安全和受控的测试。在受试者间设计中，13 名参与者体验了虚拟车辆的间隙接受场景，而 30 名参与者在相同环境中体验了真实车辆的相同场景。如果这些参与者认为两辆实验车辆之间的间隙可以安全地过马路，则指示他们开始过马路。结果表明，这两种情况下的行为相似，但也有抵消。在增强现实条件下可以观察到较低的接受率和较晚的交叉启动时间。尽管如此，事实证明，增强现实为行人研究提供了一种很有前景的工具，但也存在根据用例的局限性。
With recent advancements in head-mounted displaying technologies, virtual reality pedestrian simulators have become a common tool for traffic safety research. In contrast to field studies, test track studies and traffic observations, simulators enable researchers to analyze pedestrian behavior in a safe and controlled environment. However, creating the necessary virtual environments is time-consuming, especially in terms of meeting today’s expectations regarding graphical level of detail and realism. Furthermore, VR experiments often lack a body representation or require additional sensors to create an avatar. Due to the laboratory setting, VR simulators might fail to convey the feeling of standing on an actual street. In addition, simulators on the one hand and real-world testing on the other hand leave a methodological gap on the reality-virtuality continuum. This paper presents a novel approach for an augmented reality pedestrian simulator. With this simulator, the participant experiences virtual vehicles, augmented on a real scenario, allowing for safe and controlled testing in a realistic setting. In a between-subject design, 13 participants experienced a gap acceptance scenario with virtual vehicles, while 30 participants experienced the same scenario with real vehicles in the same environment. These participants were instructed to initiate a street crossing if they considered that the gap between the two experimental vehicles was safe to cross the street. Results indicate similar, but also offset behavior for both conditions. Lower acceptance rates and later crossing initiation times could be observed in the augmented reality condition. Still, it was shown that augmented reality renders a promising tool for pedestrian research but also features limitations depending on the use case.
