  In this paper we propose coupling conditions for a kinetic two velocity model
for vehicular traffic for junctions with diverging lanes. We consider cases
with and without directional preferences and present corresponding kinetic
coupling conditions. From this kinetic network model coupling conditions for a
macroscopic traffic model are derived. We use an analysis of the layer
equations at the junction in combination with a suitable matching procedure
with half-Riemann problems for the macroscopic model. In this way classical
coupling conditions for scalar conservation laws for traffic flow on networks
are derived from an underlying network problem.
