- Abstract:
-
Evacuation is an important measure to reduce the impacts and losses from natural disasters.Scientific and timely selection of the best evacuation path is of great significance for improving the efficiency of emergency evacuation and for the stability of society after an earthquake.For the measure of the earthquake emergency evacuation,an algorithm model of emergency evacuation arrangement and path selection based on the capacity of shelters is constructed.The model minimizes the cost of total evacuation distance for victims by considering the capacity of shelters and the uneven distribution of the population.Taking Dongcheng District and Xicheng District of Beijing as samples,the selection of the emergency evacuation route for the victims in a given scenario is studied.It is found that the capacity of the existing emergency shelters is not enough to meet the need of the residents living in the area,whether in the early stage or in the late period of an earthquake event.The evaluation model of emergency evacuation route in the disaster area based on the evacuation cost of the actual route for victims and the shelters' capacity,can not only give the best evacuation destinations and specific routes for each place on demand for evacuation,but also provide the number of the victims on demand for evacuation to different destinations as well as the number of the victims remained unevacuated.
