  Generalizing the collision term in the relativistic Boltzmann equation to
include nonlocal effects, and using Grad's 14-moment approximation for the
single-particle distribution function, we derive evolution equations for the
relativistic dissipative fluid dynamics and compare them with the corresponding
equations obtained in the standard Israel-Stewart and related approaches.
Significance of this generalization on hydrodynamic evolution is demonstrated
in the framework of one-dimensional scaling expansion.
