Abstract
The primary goal of mass evacuation in one region is to evacuate as many evacuees as possible to safe areas in the shortest time when emergency events occur. This paper chooses one scenic spot in Beijing as the research object, and uses a study method which combines by an application of real-time heat map from Baidu map in the big data era and computer simulation of the BuildingEXODUS software to put forward the emergency evacuation plan or guided strategy for evacuees. We present the orderly index to improve the efficiency of mass evacuations, and bring up a formula that demonstrates when the value of evacuation speed of individual gets closer to that of average evacuation speed of group, orderly index becomes higher. And we build a model and obtain the results of the simulation, that is,evacuation time is from 589.25 s to 443.70 s in the four case, and 443.70 s are saved by orderly guided and effective management strategy for mass evacuation. Besides, we can get the values of optimal performance statistic respectively are 0.309, 0.211, 0.128 and 0.088 according to the four cases. So it is necessary to make a reasonable guidance in the every evacuation exits to improve the efficiency of evacuation.
