Abstract: In this paper, an augmented user equilibrium model and solving algorithm are proposed and then a new approach for the O-D matrix estimation problem from link traffic flows
is also proposed. The algorithm is required only the variable of link flows, not necessary to calculate and store the variable of path flows. so the new algorithm may be applied to largescale transportation network problems. The Numerical examples are used to illustrate the applications of the proposed algorithm.
