The solution methods for optimal control problems with coupled partial differential equations as constraints are computationally costly and memory intensive; in particular for problems stated on networks, this prevents the methods from being relevant. We present instantaneous control problems for the optimization of traffic flow problems on road networks. We derive the optimality conditions, investigate the relation to the full optimal control problem and prove that certain properties of the optimal control problem carry over to the instantaneous one. We propose a solution algorithm and compare quality of the computed controls and runβtimes. Copyright Β© 2006 John Wiley & Sons, Ltd.

This paper proposes a hierarchically intelligent control procedure to resolve certain aspects of the urban traffic management problem. Three levels of the hierarchical system: the linguistic organization, the coordinator, and the on-line controller are responsible, respectively, for the management o
## Abstract This paper addresses the issues of charging, rate control and routing for a communication network carrying elastic traffic, such as an ATM network offering an available bit rate service. A model is described from which maxβmin fairness of rates emerges as a limiting special case; more g
