EFFICIENT METHOD FOR COMPUTING TRAFFIC EQUILIBRIA IN NETWORKS WITH ASYMMETRIC TRANSPORTATION COSTS

In the presence of several user categories or transportation modes, or when transportation costs on each arc of a network depend on the flows on adjacent arcs, the traffic equilibrium problem may be expressed as a variational problem. Methods for determining traffic equilibria are then adaptations of techniques for solving variational inequalities. In this paper, a new convex optimization formulation for the general traffic equilibrium problem is presented, and a simple iterative method is proposed for calculating traffic equilibria, which essentially involves postoptimizing a linear subproblem at each iteration. Preliminary computational results are reported.
