Hub and spoke network

Abstract. Hubs, as discussed in this paper, are special nodes that are part of a network, located in such a way as to facilitate connectivity between interacting places. Hubs are examined from the spatial organization viewpoint: that is, the linkages, hinterlands, and hierarchies formed by hub-and-spoke networks are described.
