The paper deals with the information which should be provided to road users in order to ensure an efficient utilization of the available road capacity. Dynamic road and traffic data, collected for example by probe vehicles, are assumed to be available. The aim is to obtain and maintain network traffic conditions corresponding to a deterministic user equilibrium, following from Wardrops principle because the total system time, which may be used as a measure for the network performance, in that case is only slightly higher than the system optimal travel time. Supplying the drivers with the equilibrium times on the links of the network will cause an incorrect route distribution of the traffic flows. In this paper we advance the idea to apply a slight adjustment to the link travel times before they are broadcasted from a central system to the network users. The centrally provided link travel times are used by on-board computing devices in every car to compute a stochastic shortest route, the result of which is offered to the driver in the form of a route advice. The proposed method is illustrated by a case study. (A) For the covering abstract see IRRD 873901.
