Continuum crowd modeling is an approach to simulating and analyzing pedestrian movement that treats a crowd as a continuous fluid-like medium rather than as a collection of discrete individuals, typically governed by partial differential equations describing density and velocity fields over a spatial domain. This macroscopic perspective matters for the field because it enables computationally tractable analysis of large-scale crowd dynamics in complex environments, supporting applications in safety planning, evacuation design, and crowd flow prediction without the prohibitive cost of agent-by-agent simulation. Key variants include Hughes' dynamic continuum model, which couples a conservation equation for pedestrian density with an Eikonal equation capturing route-choice behavior, as well as extensions that incorporate anisotropic flow, varying walking speeds, and bidirectional or multi-group pedestrian streams.
