It is predicted that the number of autonomous vehicles will increase in the forthcoming years. In this context, this research deals with autonomous micro-mobiles, specifically autonomous cargo bikes. In the development of (partially) autonomous vehicles, it is important to consider the safety perspective of vulnerable road users, such as pedestrians, already during development to enhance acceptance and widespread use. We investigated the safety parameters of speed and distance. For this purpose, videos with varying distance and speed parameters were filmed from a third-person perspective. These were then distributed via online questionnaires and evaluated by subjects regarding the subjective perceived safety. The results show that perceived safety increases with increasing passing and yielding distance and decreasing passing speed. Even at very short distances and relatively high speeds, the behavior of the cargo bike was still considered safe. These results can serve as reference values in the development of autonomous micro-mobiles. Further, the high safety perception should encourage planners and decisionmakers to give these technologies a chance and boldly tackle the mobility revolution and test possible substitutes for motorized individual transport.

关于根据距离和速度优化自动货运自行车的驾驶模式——心理学研究


据预测，未来几年自动驾驶汽车的数量将会增加。在这种背景下，本研究涉及自动微型移动设备，特别是自动货运自行车。在（部分）自动驾驶车辆的开发中，重要的是在开发过程中考虑弱势道路使用者（例如行人）的安全角度，以提高接受度和广泛使用。我们研究了速度和距离的安全参数。为此，从第三人称视角拍摄了具有不同距离和速度参数的视频。然后通过在线调查问卷分发这些数据，并由受试者对主观感知安全性进行评估。结果表明，感知安全随着通过和让行距离的增加以及通过速度的降低而增加。即使在非常短的距离和相对较高的速度下，货运自行车的行为仍然被认为是安全的。这些结果可以为自主微型汽车的开发提供参考价值。此外，高度的安全意识应该鼓励规划者和决策者给这些技术一个机会，大胆应对移动革命，并测试机动化个人交通的可能替代品。
