Pedestrian counter flows widely exist in public pedestrian facilities such as corridors, sidewalks, signalized crossings and so on. There is one specific flow in real life, namely counter flow with conflicting walking preference which often occurs in the case of presence of one-sidedly asymmetry due to shadows, light, snow and so on. It is often overlooked in practice and the related studies are still limited. In this study, to better understand the flow dynamics of pedestrian flow with various walking preference, a simple lattice-based model was proposed in which position exchange and walking preference were simultaneously considered. Specifically, simulations including pedestrian counter flow with preference (Case A), with conflicting preference (Case B), and without preference (Basic case) were performed. Results show that the presented model can capture some essential features of pedestrian counter flow with various walking preference. It is not always necessary to intervene the behavior of pedestrians ’ conflicting preference, since appropriate degree of preference is sometimes beneficial to movement of pedestrians. In addition, with the significant influence of position exchange, the flow in Case A with more orderly motion is more efficient in the context of low density, while the flow in Case B with more frequent interactions is more efficient in the case of high density. The findings in this study will be helpful in crowd management as well as the design and operation of pedestrian facilities.

使用基于格的模拟模型模拟具有冲突偏好的行人逆流

人行逆流广泛存在于走廊、人行道、信号交叉口等公共步行设施中。现实生活中存在一种特定的流动,即行走偏好冲突的逆流,这种流动通常发生在由于阴影、光线、雪等原因而存在单边不对称的情况下。在实践中经常被忽视,相关研究仍然有限。在这项研究中,为了更好地理解具有不同步行偏好的行人流的流动动力学,提出了一个简单的基于格的模型,其中同时考虑了位置交换和步行偏好。具体来说,模拟包括有偏好(案例 A)、有冲突偏好(案例 B)和无偏好(基本案例)的行人逆流。结果表明,所提出的模型可以捕获具有各种步行偏好的行人逆流的一些基本特征。并不总是需要干预行人的冲突偏好行为,因为适当程度的偏好有时有利于行人的移动。此外,由于位置交换的显着影响,在低密度的情况下,运动更有序的情况 A 中的流更有效,而交互更频繁的情况 B 中的流在高密度的情况下更有效。本研究的结果将有助于人群管理以及行人设施的设计和运营。并不总是需要干预行人的冲突偏好行为,因为适当程度的偏好有时有利于行人的移动。此外,由于位置交换的显着影响,在低密度的情况下,运动更有序的情况 A 中的流更有效,而交互更频繁的情况 B 中的流在高密度的情况下更有效。本研究的结果将有助于人群管理以及行人设施的设计和运营。并不总是需要干预行人的冲突偏好行为,因为适当程度的偏好有时有利于行人的移动。此外,由于位置交换的显着影响,在低密度的情况下,运动更有序的情况 A 中的流更有效,而交互更频繁的情况 B 中的流在高密度的情况下更有效。本研究的结果将有助于人群管理以及行人设施的设计和运营。而在高密度情况下,交互更频繁的情况 B 中的流动效率更高。本研究的结果将有助于人群管理以及行人设施的设计和运营。而在高密度情况下,交互更频繁的情况 B 中的流动效率更高。本研究的结果将有助于人群管理以及行人设施的设计和运营。
