Abstract: Compared with unidirectional and bidirectional pedestrian flow, multidirectional flow exhibit complex moving patterns, which is more complex to study. This research develops an extended cell transmission model (CTM) to simulate multidirectional crossing pedestrian flows in an area with multiple exits. The innovations of this extended model are reflected in the potential-field algorithm considering the congestion computed on the whole crowd in an area and considering exit-width differences and pedestrian emotions as parameters in the cell transmission model. Through numerical simulations and comparisons with existing models, the model’s ability to reproduce the behavior observed in the experiments is verified. The research provides insights for improving pedestrian-evacuation efficiency in facilities similar to the corridor used in the experiment.
