INFORMATION IN ROAD NETWORKS WITH MULTIPLE ORIGIN-DESTINATION PAIRS

In this paper the impact of information provision to travellers in a s tochastic network equilibrium model with multiple origin-destination ( OD) pairs is analysed. Thus far, theoretical papers addressing the sam e issue have been confined to the case of a single OD pair. Recent res earch 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 Pareto improvement. It might, however, be questioned whether this conclusion holds for mor e general networks. By constructing a network with two OD pairs result s are generated that are indicative for the impact of information prov ision in more realistic networks. It is concluded that in networks wit h multiple OD paris information provision will lead to a potential Par eto improvement, but not necessarily to a strict Pareto improvement.
