Cellular automaton simulation of building interior evacuation considering the crossable obstruction.Author(s): Huaqing Mao, Li Zhu
Building interior evacuation in the emergency scenario is becoming more and more common. However, there are lots of obstructions in the building, and most majority works are focus on how to go around those obstructions. In fact, pedestrian can cross some obstructions to reduce the evacuation time. This paper addresses this issue by presenting two concepts: cross influence zone and crossable zone, which indicate how the pedestrian cross the obstruction. The validation of the concepts was conducted with two experiments. We use the random cross probability to simulate the uncertainty of evacuation process for different gender, and the experiment results show that the evacuation time of crossable obstruction case is less than the regular obstruction case and when the random cross probability increase, the evacuation time become less.
