Combining Computational Fluid Dynamics and Agent- Based Modeling: A New Approach to Evacuation Planning.
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.
