Abstract EN
The avoidance behavior of pedestrians was characterized in the present paper by simulating the movement of crowds in both unidirectional and bidirectional pedestrian flow.
A phase change of alternative lane formation observed in real bidirectional pedestrian flows has been studied, where pedestrians tended to evade individuals in counterflow and simultaneously keep a certain distance from each other in the uniform pedestrian flow when the counterflow disappeared.
What is more, the comparison between the effect of evading and pushing behavior on evacuation has been investigated in the room egress scenario.
Additionally, the evading and overtaking behavior of fast pedestrians have also been simulated in heterogeneous crowds.
The performance of the proposed model was compared to the experimental data and the results obtained using other evacuation models.
Numerical results showed that both the phase change of alternative lane formation in bidirectional pedestrian flow and the effective evading behavior in unidirectional pedestrian flow were conductive to reduce the evacuation time of pedestrian crowds.
Even though pushing behavior of fast pedestrians seemed to improve the flow through the wide exit, it might lead to the panic and other negative effect on the crowds, such as crowds trample.
The proposed model in this paper could provide a theoretical basis for the pedestrian crowd management during emergency evacuation.
