Query: On the three-stage version of stable dynamic model   An attempt to merge into a single model, which reduces to the solution of
non-smooth convex optimization problem: calculation model of OD-matrix (entropy
model), the mode split model and the model of the equilibrium distribution of
flows (Stable dynamic model, Nesterov - de Palma, 2003). To best of our
knowledge, this is the first attempt to combine this three models. Previously
such attempts were done for other types of equlibrium models, mainly with the
BMW-model (1955), the calibration of which is significantly more difficult. We
also remark, that our model much better then traditional from computational
point of view.
