The instantaneous dynamic user-optimal (DUO) traffic assignment problem is to determine
vehicle flows on each link at each instant of time resulting from drivers using instantaneous …

A formulation of the network design problem as a bilevel linear program is presented which
admits both the convex and concave investment functions. It also allows a more general …

The manner in which the solutions produced by various methods of introducing" feedback"
into the four-step travel forecasting procedure compare with the equilibrium solution of a …
