Experimental Analysis of the Restriction Mechanisms of Queuing on Pedestrian Flow at Bottleneck

摘要

In this study we analyze the underlying restriction mechanisms when pedestrians queue through a bottleneck, and also compare them with that of setting up corridors in front of a bottleneck. A controlled laboratory experiment was conducted, by using Ultra-wideband (UWB) technology extracting the real-time pedestrians' trajectories. Different sides when pedestrians enter into the experiment room could have great impacts on the their effective speeds in the constriction process. Further, how the queuing affects the time variations of the inflow rate and the outflow rate, as well the fundamental diagrams near the exit are disclosed. The experimental results show that queuing before a bottleneck ensures orderliness and justness even if longer passing time is required, which could be favorable for non-urgent supervision.
