We deal with the transition from the classical transport to the ballistic regime. This transition is considered in the generalized Maxwell-Cattaneo context. By using an evolution equation hierarchy for higher-order moments, in the frame of extended irreversible thermodynamics, we construct a continued-fraction expansion. We derive from this latter an asymptotic expression of effective transport coefficients which yield flux limiters involving a more accurate value of ballistic velocity.
