Query: General phase transition models for vehicular traffic with point
  constraints on the flow   We generalize the phase transition model studied in [R. Colombo. Hyperbolic
phase transition in traffic flow.\ SIAM J.\ Appl.\ Math., 63(2):708-721, 2002],
that describes the evolution of vehicular traffic along a one-lane road. Two
different phases are taken into account, according to whether the traffic is
low or heavy. The model is given by a scalar conservation law in the
\emph{free-flow} phase and by a system of two conservation laws in the
\emph{congested} phase. In particular, we study the resulting Riemann problems
in the case a local point constraint on the flux of the solutions is enforced.
