During recent years,the fire disasters often happen in crowed places.Human evacuation is usually very difficult,in case of emergencies.Therefore,it is very important to standardize the evacuation of pedestrian in public gathering constructions.The shortestpath model of cellular evacuation constructed based on visibility chart can directly be applied in the plan of indicating path of actual emergency evacuation,which not only avoids high cost and unaesthetic visual caused by large quantity of escape indicating devices,and solve the large space and complex problem of largest covering size when regarding restricted quantities of escape indicating devices as restricted condition.
