Tolling analysis with Bi-objective traffic Assignment

Abstract

We present a route choice model for a toll highway network based on bi-objective user equilibrium defined as the condition that traffic arranges itself in such a way that no individual trip maker can improve either their toll or travel time without worsening the other component by unilaterally switching routes. We develop heuristic traffic assignment procedures to find bi-objective user equilibrium solutions. Finally, we demonstrate that bi-objective user equilibrium is not equivalent to a bi-objective optimisation problem by studying a three link example network. © Springer Physica-Verlag Berlin Heidelberg 2010.
