OPTIMALITY CONDITIONS FOR A DYNAMIC TRAFFIC ASSIGNMENT MODEL

A dynamic traffic assignment model formulated as a nonlinear and nonconvex mathematical program is described. Necessary optimality conditions require equalization of certain marginal costs for all the paths that are being used, and these optimality conditions are shown to be a generalization of the optimality conditions of a conventional static traffic assignment problem. The behavior of the dynamic model under static demand conditions is also examined and it is shown that in this case the model presented is a generalized version of a standard static model.
