密集的行人人群与颗粒状包装：一种类比
Dense pedestrian crowds versus granular packings: An analogy of sorts
摘要：
行人群体的动态和颗粒媒体之间的类比早就被暗示了。当人群（非常）密集时，它们似乎更有希望，在这种情况下，禁止行人的机械约束可能会战胜行人动态的决定性成分。这些类比和它们的起源探讨在两个不同的设置，（i）通过一个狭窄的瓶颈和（ii）通过入侵者的静态组装的流量。几个定量的相似性已被报道为前设置，并在这里进行讨论，而设置（ii）揭示了差异的响应模式，这是由于行人的感知能力，预期和自我推进。
英文摘要：
Analogies between the dynamics of pedestrian crowds and granular media have long been hinted at.They seem all the more promising as the crowd is (very) dense, in which case the mechanical constraints prohibiting overlapsmight prevail over the decisional component of pedestrian dynamics. These analogies and their origins are probed in two distinct settings, (i) a flow through a narrow bottleneck and (ii) crossing of a static assembly by an intruder. Several quantitative similarities have been reported for the former setting and are discussed here, while setting (ii) reveals discrepancies in the response pattern, which areascribed to the pedestrians' ability to perceive, anticipate and self-propel.
