✦ Synopsis

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 of traffic in city, neighborhood, and single intersection. Traffic situations are partitioned into five different categories, ranging from sparse to immobile traffic. For each category (except the immobile traffic which is not probed in this paper) a suitable control scheme is introduced. The control at the lowest level, single intersection, will be exerted by optimizing an assigned subgoal. Each coordination level will manage the interaction among the single intersections within its jurisdiction. A learning algorithm is incorporated at this level in order to reduce considerably the need for extensive a priori numerical computations.
