Research on the mixed multi-mode traffic assignment model under influence of ATIS

A mixed multi-mode traffic assignment model under influence of ATIS is proposed, under the hypothesis that there are many different modes in the network, different modes have symmetry effects on each other, and users´ path choices conform to the distribution of Logit type. A mathematical programming method is used to show the mixed equilibrium status. Then the equivalence of the mathematical programming method and the equilibrium conditions is proved. The existence and uniqueness of the optimum solutions are also proved. Finally a simple illustration is used to prove the correctness and feasibility of the model.
