Query: On the Braess Paradox with Nonlinear Dynamics and Control Theory   We show the existence of the Braess paradox for a traffic network with
nonlinear dynamics described by the Lighthill-Whitham-Richards model for
traffic flow. Furthermore, we show how one can employ control theory to avoid
the paradox. The paper offers a general framework applicable to
time-independent, uncongested flow on networks. These ideas are illustrated
through examples.
