The traditional spatial interaction theory applies models of travel behavior to investigate demand patterns between fixed locations. Location theory, on the other hand, takes demand as given, assumes a simple view of travel behavior, and focuses on finding the best location for facilities.EnglishTransportation costTravel behaviorValid inequalityDemand pointSpatial interaction modelBook Chapter10.1007/978-1-4419-7572-0_1210.1007/978-1-4419-7572-09781441975720
