The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
Building on past posts about our work with respect to generating large scale synthetic populations for agent-based models, we have a new paper entitled “Integrating Social Networks into Large-scale Urban Simulations for Disaster Responses” that was acc…
