A cellular automaton model based on dynamic floor-field for evacuation process with multi-egress

A cellular automaton model based on dynamic floor-field is proposed by incorporating the effect of guiding information during evacuation process. The guiding information which is regarded as an important factor to pedestrian dynamics is depicted by introducing a parameter to adjust the static value and the moving direction of pedestrians to move to the emergency exit which is not familiarized by most of the people. In addition, rules are made to deal with conflicts and the following behavior is introduced during the simulation process. Applying the proposed model, simulation of a room with two exits is presented. The simulation result shows that: (i) Several typical phenomena during pedestrian evacuation have been observed during the simulation process, e.g. arching, alignment and clogging. (ii) In comparison to the static model, guiding information has been proved as a key factor to increase the evacuation efficiency which is approximately 43.75%.
