ABSTRACT
In emergencies such as fire, pedestrian evacuation for limited visibility is significantly different from normal visibility. On the basis of the previous studies for limited visibility, the novel evacuation model is proposed. And the herd effect is achieved. More, using the programming language, pedestrian evacuation is simulated. The simulation shows that the proposed evacuation model can well reflect the process of pedestrian evacuation and the evacuation signs of reasonable design can optimize the process when the evacuation is not a jam; under the condition of the equal total width, the design with double exits improves the evacuation efficiency compared with the single exit. In most cases, the universal herd can short the evacuation time; but the contrary results are also found. In order to solve the problem and make full use of positive factors of the herd, rational herd and blind herd are introduced. The simulation results show that the rational herd has a positive effect on the evacuation in any cases.
