Experimental Study of Pedestrian Flow in a Fire-protection Evacuation Walk

As modern society develops rapidly, underground buildings are springing up all over the city, it is very essential to study pedestrian flow in the underground corridor. An evacuation experiment was conducted in a fire-protection evacuation walk in an underground market. Passing time, walking velocity, walking preference, and specific flux in the experiment are carefully analyzed. The influences of different layouts of obstacles in the corridor and pedestrian flow direction on the corridor evacuation are emphatically studied. The results include comparisons between each scene in the unidirectional and bidirectional flow, which can provide suggestions for designers and managers.
