Downtown Dynamics Model by Artificial Society Approach

Downtown revitalization has become an important policy issue, especially in advanced countries. In more than 50 years since Jane Jacobs’s discourse, the mechanism of the formation and decline of downtowns has been the subject of much controversy. It has been argued that the agglomeration and attractiveness of downtown are supported by its internal diversity. However, very little research including model analysis with an awareness of quantification has been presented.In order to examine the generation and sustainability of “downtown,” the paper outlines the Downtown Dynamics Model DDy using an artificial society approach. The paper mainly reported the formalization of externalities as the basic concept of the integration and specialization of shops, and oligo-centric market system and additional implementation applied to both the customer and shop agents in order to give a dynamic to the existing simulator ASSA. A prototype DDyn has been created on an experimental basis. _______________________________________________________ T.
