行人动态路径选择的波动

Fluctuations in pedestrian dynamics routing choices

摘要:

在几何复杂的环境中,步行行人的路径选择受到众多因素的相互作用,如当地拥挤,(估计)到达目的地的时间,(感知)舒适度。随着个人选择的结合,宏观交通流模式出现。了解在复杂几何环境中产生宏观交通分布的物理机制是一个突出的科学挑战,在拥挤的行人设施的设计和管理的影响。在这项工作中,我们分析,通过广泛的现实生活中的行人跟踪数据,单向流动动力学在一个不对称的设置,作为许多常见的复杂几何形状的原型。我们的环境是由一个主要的人行道和一个稍长的绕道。我们的测量数据是在荷兰埃因霍温举行的一次专门的高精度行人跟踪活动中收集的。我们表明,动态可以通过引入集体不适函数进行定量建模,并且单个个体行为的波动对于正确恢复全局统计行为至关重要。值得注意的是,所观察到的交通分流基本上偏离了最佳的交通方式分区,因为全球行人吞吐量没有最大化。

英文摘要:

Routing choices of walking pedestrians in geometrically complex environments are regulated by the interplay of a multitude of factors such as local crowding, (estimated) time to destination, (perceived) comfort. As individual choices combine, macroscopic traffic flow patterns emerge. Understanding the physical mechanisms yielding macroscopic traffic distributions in environments with complex geometries is an outstanding scientific challenge, with implications in the design and management of crowded pedestrian facilities. In this work, we analyze, by means of extensive real-life pedestrian tracking data, unidirectional flow dynamics in an asymmetric setting, as a prototype for many common complex geometries. Our environment is composed of a main walkway and a slightly longer detour. Our measurements have been collected during a dedicated high-accuracy pedestrian tracking campaign held in Eindhoven (The Netherlands). We show that the dynamics can be quantitatively modeled by introducing a collective discomfort function, and that fluctuations on the behavior of single individuals are crucial to correctly recover the global statistical behavior. Notably, the observed traffic split substantially departs from an optimal, transport-wise, partition, as the global pedestrian throughput is not maximized.
