Given a layout domain from a real world layout, our approach synthesizes crowd-aware layouts by considering the crowd flow properties of visitors: mobility, accessibility and coziness. Evaluation by crowd simulation software shows that our synthesized layouts exhibit improved crowd flow properties compared to the input real world layouts. Three-dimensional visualization on the right shows the flow of human crowds in a shopping mall created using the synthesized layout on the left.

Abstract

We propose a novel approach for designing mid-scale layouts by optimizing with respect to human crowd properties. Given an input layout domain such as the boundary of a shopping mall, our approach synthesizes the paths and sites by optimizing three metrics that measure crowd flow properties: mobility, accessibility, and coziness. While these metrics are straightforward to evaluate by a full agent-based crowd simulation, optimizing a layout usually requires hundreds of evaluations, which would require a long time to compute even using the latest crowd simulation techniques. To overcome this challenge, we propose a novel data-driven approach where nonlinear regressors are trained to capture the relationship between the agent-based metrics, and the geometrical and topological features of a layout. We demonstrate that by using the trained regressors, our approach can synthesize crowd-aware layouts and improve existing layouts with better crowd flow properties.
