One approach to modeling flows in the socio-technical systems, for
example road traffic, reduces to decompose the movement of the
collective and the individual components. A collective component is
described by a system of differential equations, and an individual
component corresponds to stochastic movement within the cell
decomposition defined by the collective modes. This monograph discusses
both components with varying degrees of detail including the regular
networks. Moreover we study the cluster model as a simplified analogue
of structures, following from hydrodynamic approaches, and can be
applied for investigation of multi-lane flows on networks. Basic
characteristics of the models are researched.
