An assessment of computerized planning models and data bases

Abstract

Urban planning models have had and continue to have a significant impact on public policy making. A review of their influence over the past 20 years demonstrates which urban models have worked and which have not. Three current models are drawn upon for application to future plans; the Lowry-type model is favored. More sophisticated computer capabilities together with past improvements in statistical methods promise to strengthen the validity of specific models to urban policy in the 1980s. Accordingly, a detailed overview is given of the changes that need to be made in both model-building and application if the anticipated progress is to be realized.
