AnalogiesNicolas, Alexandre between the dynamics of pedestrian crowdsCrowd dynamics and granular mediaGranular 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 overlaps might prevail over the decisional component of pedestrian dynamicsPedestrian 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 are ascribed to the pedestrians’ ability to perceive, anticipate and self-propel.
