A Study on Characteristics of Passenger Collective Behaviors on Urban Rail Transit Stations

To investigate the characteristics of passenger collective behaviors on urban rail transit stations,this paper introduces a concept called passenger-flow-calming to describe the relief of passenger flow instability.By analyzing the characteristics of facilities and space-time distribution of passenger flow,the study used the passenger collective behavior model andsimulation experiment to identify the elements that affect passenger-flow-calming from three passenger traffic flow parameters: volume,density and speed,in order to reveal the internal mechanism of sudden change of the passenger flow.The experiment results show that the relative distance between the facilities has a direct effect on the decrease of average passenger flow rate and the relative capacity of corridor entrance/exit affects pas-senger density,which relate to the internal passenger volume.The study also show that interweaving passenger flow clearly impacts the speed of passenger flow and the passenger flow density.Based on the above results,the paper makesfew suggestions on how to reasonably guide and control passenger flow in passenger volume,density and speed respectively.
