Dynamic Urban Growth Models

摘要

The report describes the further development of the dynamic models of urban evolution derived from concepts of self-organization that have recently emerged in the physical sciences. The first section contains the new inter-urban model which describes the evolution of an interacting hierarchy of urban centers and the development of internal structure within each center. It is shown how mutual interactions between elements of the system lead to a self-organization of the system through successive instabilities of the collective structure. The second section introduces the techniques of Boolean algebra to describe the evolution of the internal structure of a city and how these techniques may be used by urban planners. The final section illustrates the importance of behavioral fluctuations in transportation mode choice showing how a system reorganizes itself with critical size thresholds are exceeded.
