  This paper deals with the kinetic theory modeling of crowd dynamics with the
aim of showing how the dynamics at the micro-scale is transferred to the
dynamics of collective behaviors. The derivation of a new model is followed by
a qualitative analysis of the initial value problem. Existence of solutions is
proved for arbitrary large times, while simulations are developed by
computational schemes based on splitting methods, where the transport equations
treated by finite difference methods for hyperbolic equations. Some preliminary
reasonings toward the modeling of panic conditions are proposed.
