Non-local first-order modelling of crowd dynamics: a multidimensional framework with applications [PDF]

, 2010
In this work a physical modelling framework is presented, describing the intelligent, non-local, and anisotropic behaviour of pedestrians. Its phenomenological basics and constitutive elements are detailed, and a qualitative analysis is provided.
