这项研究调查了行人在拥挤地区行驶时为躲避他人而采取的身体旋转行为。在这种情况下，人体方向往往与行走方向不同，例如行人可能会走到一边，通过定量评估狭窄走廊中逆流的身体旋转来研究碰撞避让过程中身体方向与步行方向的偏差。进行了简单的实验，其中两个行人互相超过。研究发现，当走廊宽度小于两个行人宽度之和时，行人会旋转身体。通过分析狭窄走廊中两个相互外接的椭圆的几何形状，可以解释这种行为。建立了初步模型，并成功地模拟了人体在通过过程中的姿态与行走方向的偏差；最后，进行了比通过实验更复杂、更逼真的横流实验，证实了在复杂和真实场景中，身体旋转行为也是一个关键因素。
This study investigated the body-rotation behavior adopted by pedestrians to avoid others while moving in congested areas. In such scenarios, body orientation often differs from walking direction, e.g., a pedestrian may step sideways.The deviation between body orientation and walking direction during collision avoidance was studied by quantitatively evaluating the body rotation for counter-flows in narrow corridors. Simple experiments, in which two pedestrians passed each other, were conducted. It was found that pedestrians rotated their bodies when the corridor width was smaller than the sum of the widths of the two pedestrians. This behavior was explained by analyzing the geometry of two ellipses circumscribing each other in a narrow corridor. A preliminary model was developed, and the deviation between the body orientation and walking direction during passing was successfully simulated.Finally, a cross-flow experiment, which is much more complex and realistic than the passing experiments, was performed; it was confirmed that body rotation behavior is also a critical factor in complex and realistic scenarios.
