目的：目前，轮式移动设备的无障碍标准使用1.5米的转弯圈，旨在容纳手动轮椅。 踏板车的机动性不如轮椅，所以允许一个完整的转弯圈将需要太多的空间。相反，我们建议使用一个矩形，为三点转弯提供空间。在这里，我们确定这种方法的面积要求。方法：对于不同长宽比的矩形“房间”，我们测量了两个四轮滑板车（Celebrity-X和Fortress-1700）的最小尺寸，这两个四轮滑板车联合收割机良好的室外性能和合理的室内机动性，可以进入空间，执行三点转弯和退出。 可移动的聚苯乙烯泡沫塑料墙定义了每个“房间”，一个门口位于空间的角落附近或一面墙的中间。“房间”的大小被减少，直到我们的专家司机不能再执行操纵。结果。与转弯圆所需的面积相比，节省了42-54%。 相对于现有的需求，Celebrity-X需要增加53-95%的空间; Fortress-1700需要增加173-223%的空间。结论：当容纳四轮滑板车时，我们提出的三点转弯定义将需要比当前标准更多的空间，但比使用完整转弯圆要少得多。
Purpose. Accessibility standards for wheeled mobility devices currently use a 1.5 m turning circle, designed to accommodate manual wheelchairs. Scooters are less manoeuvrable than wheelchairs, so allowing a full turning circle would require too much space. Instead, we propose using a rectangle that provides space for a three-point turn. Here, we determine the area requirements of this approach. Method. For rectangular ‘rooms’ of varying aspect ratios, we measured the minimum dimensions in which two four-wheeled scooters (the Celebrity-X and Fortress-1700), which combine good outdoor performance with reasonable indoor manoeuvrability, could enter the space, perform a three-point turn and exit. Moveable Styrofoam walls defined each ‘room’, and a doorway was located either near the corner of the space or in the middle of one wall. ‘Room’ size was decreased until our expert driver could no longer perform the manoeuvre. Results. Compared to the area required for a turning circle, 42–54% savings were achieved. Relative to existing requirements, 53–95% more space is required to accommodate the Celebrity-X; 173–223% increases are necessary for the Fortress-1700. Conclusions. When accommodating four-wheeled scooters, our proposed three-point turn definition would require more space than the current standards, but considerably less than if a full turning circle were used.
