Samenvatting
This article presents models and strategies for dynamic route guidance. The problem of route guidance is formulated in terms of optimal control. A decentralized method for estimating state variables and time varying parameters is proposed. The results for that estimation method show that the vehicles must send their destinations to the system if a good estimation is needed. A decentralized heuristic is used to solve the optimal control problem. The optimization results show that this heuristic improves clearly the traffic with relation to a free speed shortest path routing. (A)
