Hub system

A transport network system in which a carrier routes heavily trafficked flights or voyages among a few large air or sea ports called hubs or base ports, rather than making direct calls on smaller ones. The respective hinterlands of each hub are called spokes and are served with smaller equipment such as commuter aircraft, feeder vessels, barges or ground transportation. The concept resembles wheels, with the spokes radiating from their central hubs. See also base port; feeder vessel.
