中文简介: | 整个城市乃至整个地区的疏散是一个重要的问题,最近发生的一些事件就证明了这一点,如丽塔飓风事件中的休斯顿疏散,海啸事件中的沿海城市疏散。针对如此大规模的灾害,建立一个健壮灵活的仿真框架有助于对疏散过程进行预测。此外,可以提前识别瓶颈,从而消除这些瓶颈。这将为面临自然灾害高风险的城市或地区带来更好的准备。现有的方法要么是针对较小的问题(如细胞自动机技术或基于微分方程的方法),要么不是微观的(如基于动态流量分配的方法)。我们的工作使用了一种既微观又能处理大问题的技术。该模拟应用于印尼巴东市。这座城市面临着被地震引发的海啸淹没的高风险。 |
课程简介: | The evacuation of whole cities or even regions is an important problem, as demonstrated by recent events such as the evacuation of Houston in the case of Hurricane Rita, or the evacuation of coastal cities in the case of tsunamis. A robust and flexible simulation framework for such large scale disasters helps to predict the evacuation process. Furthermore, it is possible to recognize bottlenecks in advance, so that an elimination of those bottlenecks is possible. This should lead to a better preparedness for cities or regions that face a high risk of natural disasters. Existing methods are either geared towards smaller problems (e.g. Cellular Automata techniques or methods based on differential equations) or are not microscopic (e.g. methods based on dynamic traffic assignment). Our work uses a technique that is both microscopic and capable to process large problems. The simulation is applied to the Indonesian city of Padang. The city faces a high risk of being inundated by an earth quake triggered tsunami. |
