Core frame model

Core frame model

The Core frame model is a model showing the urban structure of the Central Business District of a town or city. The model was first suggested by Ronald R. Boyce and Edgar M. Horwood in 1959.[1]

The model includes an inner core where land is expensive and used intensively, resulting in vertical development. This area is the focus of the transport system and has a concentrated daytime population. The outer core and frame have lower land values and are less intensively developed.[2] The various land uses are linked to the bid rent theory. The zone of assimilation and zone of discard are together called the zone of transition.
