摘要：
The dynamic and uncertain environment will cause the uncertainty of the initial status of passengers, evacuation behavior, and the global evacuation path. Considering those problems mentioned above, an agent-based model of dynamic evacuation behavior switch is established, which is able to describe passengers's witch from various evacuation behaviors with the cost of change. On the other hand, according to the spatial cohesion from the normal simulation, the approach for global path finding based on optimized Dijkstra algorithm is proposed. Finally, simulation on emergency evacuation is conducted in the case of a particular metro station. The result validates that the model is feasible and can reflect environmental effects on passengers' evacuation process dynamically. Meanwhile, the simulation precision is further improved, which enables to evaluate emergency plan with accuracy. Copyright © 2018 by Science Press.
