Mixed stochastic user equilibrium behavior under traveler information provision services with heterogeneous multiclass multicriteria decision making

Abstract

This paper studies travellers? mixed stochastic user equilibrium (SUE) behaviour under traveller information provision services with heterogeneous multi-class multi-criteria decision making. A multi-class, multi-criteria mixed SUE assignment model under traveller information provision services is proposed and modelled as a nonlinear complementary problem (NCP). The model considers heterogeneous road travellers who are assumed to be multi-criteria decision makers. The route choice behaviour of equipped and unequipped travellers under traveller information provision services is then formulated as an optimisation program, in which the net economic benefit is maximised and the total generated emissions are constrained. The optimisation model has an interpretation from economic, behavioural and environmental viewpoints. The solution of this program satisfies the logit-based SUE assignment. By deriving first-order optimality conditions from this program, the marginal cost pricing policy is obtained. This pricing is not only class-dependent but also link-dependent.
