Body rotation is a common behavior in pedestrian flow dynamics. In this paper, an improved least-effort model is proposed to reproduce this behavior and other pedestrian flow characteristics. In this model, the pedestrian chooses the velocity and angle of body rotation according to the minimum energy cost. The energy cost includes the caloric expenditure in the walking, collision loss and body rotation cost. In order to validate the accuracy of the model, an experiment is conducted to investigate the bypassing/crossing and body rotation behavior quantitatively. The pedestrian can choose to walk through the exit or pass by the wall next to the exit, in order to reach the target place. When the exit is narrow, the pedestrian prefers to pass by the short wall, but cross through the exit in long-wall cases. As the exit gets narrower, the rotation angle increases. In the multi-pedestrian simulation, the pedestrian can avoid collision in the narrow corridor by body rotation. The body ...

基于考虑人体旋转的改进的最小努力模型的行人流特征

身体旋转是行人流动力学中的常见行为。在本文中，提出了一种改进的最小努力模型来重现此行为和其他行人流特征。在该模型中，行人根据最小的能量消耗选择身体旋转的速度和角度。能源成本包括步行中的热量消耗，碰撞损失和身体旋转成本。为了验证模型的准确性，进行了实验以定量研究旁路/交叉和车身旋转行为。行人可以选择穿过出口，也可以通过出口旁的墙，以到达目标位置。当出口狭窄时，行人倾向于穿过短墙，但在长壁情况下穿过出口。随着出口变窄，旋转角度增加。在多行人模拟中，行人可以通过身体旋转避免在狭窄走廊中发生碰撞。身体 ...
