MODELLING AND SYSTEMS ANALYSIS IN URBAN PLANNING

POLICY, DESIGN AND UNDERSTANDING ARE THE THREE PRINCIPAL ASPECTS OF URBAN PLANNING. BY POLICY IS MEANT THE ESTABLISHMENT OF GOALS AND THE MEANS BY WHICH THEY ARE TO BE ATTAINED. IN DESIGN, ALTERNATIVE PLANS AND THEIR LIKELY CONSEQUENCES ARE EVALUATED BY A VARIETY OF TECHNIQUES. FOR THE UNDERSTANDING OF THE SYSTEM BEING PLANNED, A MODEL IS SET UP SO THAT THE HYPOTHESES AND THEORIES ABOUT THE SYSTEM CAN BE TESTED. THE AIM OF THIS ARTICLE IS TO OUTLINE THE USE OF MODELLING AND SYSTEMS ANALYSIS IN URBAN PLANNING. MODELS ARE FORMAL REPRESENTATIONS OF THEORIES. THE TRADITIONAL ACADEMIC DISCIPLINES OF DEMOGRAPHY, ECONOMICS, SOCIOLOGY AND GEOGRAPHY EACH COVER PART OF THE FIELD OF URBAN STUDIES WITH CORRESPONDING THEORIES. BUT THESE THEORIES OFTEN DO NOT LEND THEMSELVES TO QUANTITATIVE REPRESENTATION IN MODELS, PROBABLY BECAUSE THEY REPRESENT INCOMPLETE, OR LESS THAN ADEQUATE, UNDERSTANDING. THE ONLY MODEL WHICH IS ANYTHING LIKE ADEQUATE IS THE TRANSPORT MODEL. MATHEMATICAL MODELS OR URBAN TRANSPORT FLOWS HAVE BEEN USED IN MANY STUDIES, INCLUDING THOSE BEING CARRIED OUT IN ALL THE MAJOR CONURBATIONS OF BRITAIN, AS FOR EXAMPLE, IN LONDON. THESE ARE THE ONLY INTRA-URBAN MODELS WHICH ARE BEING USED CONTINUOUSLY BY PLANNERS. THE OTHER SUB-MODELS HAVE SOMETIMES BEEN BUILT WITHIN MORE COMPREHENSIVE URBAN DEVELOPMENT MODELS, AND SOMETIMES INDIVIDUALLY. /AUTHOR/
