Variational Inequality Equilibrium Model for Multiclass and Multicriteria Stochastic Traffic Networks with Elastic Demands

  • An equilibrium model for multiclass and multicriteria stochastic traffic networks with elastic demands was established using variational inequality method under assumptions that the weights of criteria are dependent of classes of travelers, and that cost functions are unsymmetrical.The model generalizes the equilibrium model for stochastic traffic networks of single class of travelers.It was proved that the continuity and strict monotonicity of mappings in the variational model ensure the existence and uniqueness of equilibrium flows,respectively.Generalized travel cost for a road section is affected by demands and traffic flows on other related road sections,and is a function of flows on all roads.This variational inequality is solved with a diagonal algorithm.An example was presented to show the feasibility of the proposed model and the algorithm.
