Rethinking Urban Redevelopment The Viewpoint of a Small City

The authors present in this article the results of the first stages in the development of a model of urban growth which depends heavily on transportation concepts and which makes use of a modification of Morton Schneider's intervening opportunity model (ordinarily applied to trip distributions). In requiring the operator of the model to estimate activity densities, this paper recalls Hamburg's contribution to the Journal of six years ago, but the methods used for distributing growth appear to be much more realistic. The authors express the hope that levels of activity densities may in the future be established within Che model. The paper is especially noteworthy for the attention it gives to the problems of designing a flexible and easily used model and of establishing good communication between the computer and the analyst in the form of legible and usable outputs. Many of these results are reproduced here and the design criteria for the model are summarized at the conclusion of the article.
