Research highlights ► Pedestrian route choice behavior and physical congestion during the evacuation of indoor areas with internal obstacles are modeled on a new-constructed network. ► Collection, spillback and dissipation behavior of pedestrians passing through bottlenecks are explored. ► A modified cell transmission model with regular hexagonal cells is proposed.
Abstract We present a method of predicting pedestrian route choice behavior and physical congestion during the evacuation of indoor areas with internal obstacles. Under the proposed method, a network is first constructed by discretizing the space into regular hexagonal cells and giving these cells potentials before a modified cell transmission model is employed to predict the evolution of pedestrian flow in the network over time and space. Several properties of this cell transmission model are explored. The method can be used to predict the evolution of pedestrian flow over time and space in indoor areas with internal obstacles and to investigate the collection, spillback, and dissipation behavior of pedestrians passing through a bottleneck. The cell transmission model is further extended to imitate the movements of multiple flows of pedestrians with different destinations. An algorithm based on generalized cell potential is also developed to assign the pedestrian flow.
