Résumé / Abstract
The problem of designing integrated traffic control strategies for motorway networks with the use of ramp metering, route guidance, and motorway-of-motorway control measures is considered in this paper. A generic problem formulation is presented in the format of a discrete-time optimal control problem whose numerical solution is achieved by use of a feasible-direction algorithm. As an illustrative example, a relatively simple motorway network is considered under different control scenarios. In each case the optimal control strategy is discussed along with its effect on the traffic flow process. The results demonstrate the efficiency of the proposed approach as well as the genuinely intelligent behavior of the designed control strategy. (document disponible en version électronique).
