Abstract:

In this paper, we develop a multiclass, multicriteria traffic network equilibrium model in which travelers of a class perceive their travel disutility or generalized cost on a route as a weighting of travel time and travel cost, each of which is flow-dependent. In addition, the weights are not only class-dependent but also link-dependent. The model is an elastic demand model and allows the demand function for each class and origin/destination (O/D) pair to depend, in general, upon the disutilities of all classes at all O/D pairs. The formulation of the governing equilibrium conditions, as well as the qualitative analysis, and the computational procedure, are based on finite-dimensional variational inequality theory. The model provides an alternative to existing multimodal and multicriteria traffic network equilibrium models and has location choice implications as well.
