Description
The programme examines the use of mathematical models to help developers decide where to build new shopping centres, and to assess the impact these will have on existing centres.

Footage description: Film shots of the Bretton Shopping Centre, Peterborough. Keith Attenborough (voice over) introduces the programme with a brief description of the centre and why it was built. Andrew Broadbent joins in. Over still shots of the Carrefour Hypermarket at Eastleigh, Hants., Keith Attenborough briefly describes the centre and explains how a mathematical model was used at a public enquiry on whether or not the centre should be built. Tim Rhodes joins in. Keith Attenborough briefly gives the background on the decision to develop a mathematical shopping model for an appeal against the decision to build a shopping centre at Haydock Park. David Foot explains what questions the model was designed to answer. Attenborough goes on to list those data of interest to planners and developers which may be obtained with the aid of a mathematical model. Attenborough and Mike Batty discuss some of the variables which make up such a model. Animated maps help to illustrate points made, Batty goes on to explain how boundaries of regions are chosen for the model. Animated maps help illustrate points made. Batty explains why expenditure flows are important variables in the model. He goes on to show how the modeller finds a value for money flow. Captioned graphics help to illustrate his points. Batty next explains how shopping centre attractiveness is quantified for the model. Captioned graphics help to illustrate points. Attenborough and Batty explain how distance is taken into account in a shopping model. Batty explains why distance is measured in terms of travel time rather than linear distance. They go on to discuss how distances between zones are measured and how the points, within zones, from which measurements are taken, are plotted. An animated map helps to illustrate points made. Batty and Attenborough go on to discuss how the distance measurement is incorporated in the model, using an inverse relationship and a negative exponential function. Batty discusses the value of using a negative exponential function in the model when small distances are involved. Attenborough and Batty arrive at the final form of the model's equation. A caption board illustrates points made. The three models examined in the programme are discussed, critically, by the planners who were involved in implementing them - Andrew Broadbent David Foot, Tim Rhodes.
