New Insights Into Pedestrian Flow Through Bottlenecks

An important tool for pedestrian facility design and dimensioning is capacity estimation. Considerable differences with respect to the estimated flow values are shown in different procedures and specifications in the literature. A stepwise capacity growth with width is indicated by new experimental data, moreover, which thus challenges the specific flow concept validity. Under laboratory conditions, the authors experimentally studied unidirectional pedestrian flow through bottlenecks to resolve these differences. The authors present time development of quantities such as individual time gaps, density, and individual velocities in bottlenecks of different widths. A linear growth of flow with width is shown in the data. Comparing study results with experimental data from other authors indicates that the basic bottleneck capacity estimation assumption has to be revised. The main study result, in contrast to most planning guidelines, is that even if the incoming flow does not overstep the maximum flow defined capacity according to the fundamental diagram, a jam occurs.
