Sci. 18, Suppl., 1217-1247 (2008).} \itemab Summary: This paper deals with the mathematical modelling of crowd dynamics within the framework of continuum mechanics. The method uses the mass conservation equation closed by phenomenological models linking the local velocity to density and density gradients. The closures take into account movement in more than one space dimension, presence of obstacles, pedestrian strategies, and modelling of panic conditions. Numerical simulations of the initial-boundary value problems visualize the ability of the models to predict several interesting phenomena related to the complex system under consideration. \itemrv{~} \itemcc{} \itemut{Crowd dynamics; conservation equations; nonlinearity; panic conditions} \itemli{doi:10.1142/S0218202508003017} \end
