Simulation Research On Pedestrian Flow Of Subway Station Considering Heterogeneous Individuals

Pedestrian simulation research is widely used in safety science,pedestrian transportation,social science,and group dynamics.At present,the microscopic simulation of pedestrians is not sufficient to simulate pedestrian behavior in detail.Since each pedestrian attribute contains more content,it is impossible to perform a completely pseudoheterogeneous pedestrian simulation experiment.Based on the extensive reading and collation of relevant literatures,this paper makes an in-depth analysis of pedestrian behavior characteristics.This paper firstly proposes the correlation between heterogeneous individuals and heterogeneous individual behaviors on the population density changes from the perspective of risk management.Secondly,the individual pedestrian diversity and attribute differences are further refined,and the heterogeneous individuals are separated by a single variable that changes the pedestrian individual in the ped source module through simulation software.Finally,the simulation model of walking structures with different structures is established,and the simulation of heterogeneous individual pedestrians is carried out to study the influence of heterogeneous individuals and population density and speed and the impact on subway evacuation time.Introduce the crowding force model to calculate the size and time of the individual's congestion and time to facilitate the quantification and evaluation of the risk,provide testing services for the relevant programs or formulate relevant plans based on the simulation results,and special circumstances in the dense crowds of the facilities of the subway station control,monitor the dynamic changes in the density and speed of the crowd,avoid the adverse effects of heterogeneous individuals on the population,prevent the occurrence of pedestrian trampling accidents,and ensure public safety.
