In this paper the impact of information provision to travellers in a stochastic network equilibrium model with multiple origin-destination (OD) pairs is analysed. Thus far, theoretical papers addressing the same issue have been confined to the case of a single OD pair. Recent research showed that under the assumption of a single OD pair information provision is beneficial to both the informed and uninformed drivers, and hence information provision leads to a strict Pareta improvement. It might, however, be questioned whether this conclusion holds for more general networks. By constructing a network with two OD pairs results are generated that are indicative for the impact of information provision in more realistic networks. It is concluded that in networks with multiple OD pairs information provision will lead to a potential Pareto improvement, but not necessarily to a strict Pareto improvement. (A)
