A multiclass, multicriteria traffic network equilibrium model

In this paper, we develop a multiclass, multicriteria traffic network equil ibrium model in which travelers of a class perceive their travel disutility on a route as a weighting of travel time and travel cost. The model explic itly treats congestion in the network and provides an alternative to existi ng multimodal traffic network models. The formulation of the governing equi librium conditions, as well as the qualitative analysis, and computational procedure are based on finite-dimensional variational inequality theory. Th e numerical examples illustrate the effectiveness of the computational appr oach as well as the model. (C) 2000 Elsevier Science Ltd. All rights reserv ed.
