This model describes for instance the macroscopic motion of a crowd with individual congestion preferences. We propose an asymptotic preserving (AP) scheme based on a conservative formulation of the system in terms of density, momentum and density fraction. A second order accuracy version of the scheme is also presented. We validate the scheme on one-dimensional test-cases and extended here to higher order accuracy. We finally carry out two dimensional numerical simulations and show that the model exhibit typical crowd dynamics.", "revisions": [ { "version": "v1", "updated": "2017-05-02T12:08:03.000Z" } ], "analyses": { "keywords": [ "finite volume approximations", "euler system", "variable congestion", "second order accuracy version", "higher order accuracy" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
