Abstract

In this paper, we consider a signal-controlled road network with link capacity expansions. This network design problem can be formulated as a constrained optimization subject to equilibrium flows. A projected Quasi-Newton method is proposed to find good local optimal solutions. Numerical calculations are conducted using a real data road network and large-scale grid networks.
