Streamline Simulation and Analysis of Pedestrian Weaving Flow in Large Passenger Terminal

A new concept called the extended weaving area is proposed to relieve the conflicts and clogging caused by pedestrian weaving in both time and space in large passenger terminal. The cellular automaton model that considers pedestrian walking habits based on the floor field is adopted. Numerical simulations are carried out in MATLAB environment to explore the relationship between the emptying time and bottleneck setting when four groups of pedestrians walk to four exits through the weaving areas with different settings. It is found that, by using improved extended weaving area settings, the stress of the weaving area could be relieved in both time and space; thus the efficiency of pedestrians passing could be improved. Based on the simulation, the threshold of single bottleneck width in the extended weaving area is also given in this research.
