Clogging in Velocity-Based Models for Pedestrian Dynamics

摘要

In the simulation of pedestrian bottleneck flow with velocity-based models stable clogging could be observed, which is not in line with the movement of pedestrians in the real world. Four velocity-based models with different structures are selected in this paper to explore the cause of the phenomenon by identifying and analysing stable clogging. A series of simulations of pedestrians moving through a bottleneck are designed to investigate the decisive factors behind the unrealistic stable clogging, which includes the width of the exit, the flow of the pedestrian at the entrance and the size of the simulation time-step. The result of simulations with different models are compared and analyzed.
