行人原型扩展——更多用于自动驾驶车辆安全测试的行人模型

摘要

在我们此前的工作《行人原型》中，我们将行人原型定义为能够唯一识别特定类型行人的行为集合。第一篇论文提出了12种行人原型，包括漫游者、醉汉、分心者、闪现者、犹豫者、盲行者、结群者、乱穿马路者、老年人、儿童、多事者以及驻留行人。引入这些原型是为了超越单一行为标签，从而以更自然的方式描述危险行人在真实交通场景中如何逐步表现出危险行为。然而，在对YouTube行车记录仪视频进行进一步标注后，我们识别出另外7种行人原型，它们与先前提出的原型在行为上存在可观察且显著的差异。这些新原型捕捉到了原有分类体系无法完全解释的行人行为模式。在本预印本中，我们介绍每一种新原型，定义其必要行为与可选行为，说明其与先前提出的原型之间的区别，并提供展示该原型实际表现的视频帧证据。

In our prior work, Pedestrian Archetypes, we defined pedestrian archetypes as collections of behaviors that uniquely identify a specific type of pedestrian. The first paper proposed 12 pedestrian archetypes, including the Wanderer, Drunk, Distracted, Flash, Indecisive, Blind, Flock, Jaywalker, Elderly, Kid, Eventful, and Parked Pedestrian. These archetypes were introduced to move beyond single behavior labels and provide a more natural way to describe how dangerous pedestrians actually behave progressively in real-world traffic scenarios. However, upon further annotation of YouTube dash-cam videos, we identified 7 additional pedestrian archetypes with observable and significant behavioral differences from the previously proposed ones. These new archetypes capture pedestrian behavior patterns that could not be fully explained by the original taxonomy. In this pre-print, we introduce each new archetype, define its essential and optional behaviors, explain how it differs from previously proposed archetypes, and provide video-frame evidence showing the archetype in action.
