冲入交通：研究外部人机接口用于自动驾驶车辆与跑步者交互
Running into Traffic: Investigating External Human-Machine Interfaces for Automated Vehicle-Runner Interaction
AI总结：
研究探讨了自动驾驶车辆与跑步者交互中外部人机接口的有效性，发现跑步者对eHMI的依赖性高于步行者，且更偏好颜色变化而非动画。
摘要：
自动驾驶车辆（AVs）必须在交叉口向行人传达让行意图。外部人机接口（eHMIs，车载显示屏）是可行的解决方案，但主要在步行者上进行测试。跑步者作为重要的人群，移动速度更快，面临不同的身体和感知需求，引发了关于行人活动如何影响eHMI使用的问题。我们使用增强现实模拟器进行了户外研究。参与者在行走和跑步时导航虚拟交叉口；接近的AV显示三种eHMI之一：红色/绿色变色灯、动画青色灯或无eHMI。无eHMI始终表现不佳。步行者大多停止并验证eHMI信号与车辆行为；他们有效处理了eHMI动画和颜色变化。跑步者面临更大的过马路时间压力，增加了对eHMI的依赖，超过车辆行为。他们更喜欢颜色变化而非动画用于快速决策。这些发现对于促进eHMI包容性和身体健康至关重要，随着AVs加入我们的道路。
英文摘要：
Automated vehicles (AVs) must communicate their yielding intentions to pedestrians at crossings. External Human-Machine Interfaces (eHMIs, on-vehicle displays) are promising solutions, but were primarily tested with walking pedestrians. Runners are a significant pedestrian group who move faster and face distinct bodily and perceptual demands, raising questions about how pedestrian activity influences eHMI use. We conducted an outdoor study using an augmented reality simulator. Participants navigated a virtual crossing while walking and running; an approaching AV displayed one of three eHMIs: red/green colour-changing lights, animated cyan lights, or no-eHMI. No-eHMI consistently underperformed. Walkers mostly stopped and validated eHMI signals with vehicle behaviour; they processed both eHMI animations and colour changes effectively. Runners experienced greater time pressure to cross, increasing reliance on the eHMI over vehicle behaviour. They preferred colour changes over animation for rapid decisions. These findings are crucial for promoting eHMI inclusivity and physical wellbeing as AVs join our roads.
