我们介绍了一种新的混合两个领域-计算流体动力学(CFD)和基于代理的建模(ABM)-作为一个强大的新技术,城市疏散规划。CFD是模拟污染物空中运输的主要技术,而ABM是模拟适应性个体群体中社会动力学的有力方法。混合CFD-ABM方法是能够模拟多大,空间分布的人口可能会响应一个物理现实的污染物羽。我们证明了CFD-ABM疏散设计的整体可行性,使用的情况下,假设在洛杉矶的气溶胶释放,探索各种政策制度的潜在有效性。最后,我们认为,这种新的方法可以有力地适用于任意人口中心,提供了一个前所未有的准备和灾难性事件的响应工具。
We introduce a novel hybrid of two fields—Computational Fluid Dynamics (CFD) and Agent-Based Modeling (ABM)—as a powerful new technique for urban evacuation planning. CFD is a predominant technique for modeling airborne transport of contaminants, while ABM is a powerful approach for modeling social dynamics in populations of adaptive individuals. The hybrid CFD-ABM method is capable of simulating how large, spatially-distributed populations might respond to a physically realistic contaminant plume. We demonstrate the overall feasibility of CFD-ABM evacuation design, using the case of a hypothetical aerosol release in Los Angeles to explore potential effectiveness of various policy regimes. We conclude by arguing that this new approach can be powerfully applied to arbitrary population centers, offering an unprecedented preparedness and catastrophic event response tool.
