Abstract
Batty M., Foot D. et al. (1973) Spatial system design and fast calibration of activity interaction-allocation models, Reg. Studies 7, 351–366. This paper explores certain questions of model design relating to activity interaction-allocation models. A major problem concerns the spatial definition and required number of zones in such models, and an elementary theoretical analysis of this zoning problem is attempted. The effect of space on the model is investigated in terms of the problem of measuring locational attraction, and the effect of aggregating a zoning system on model performance is assessed using a model of the Northampton region. Calibration of such models is discussed in terms of response surfaces, and a fast calibration technique known as the Newton-Raphson method is introduced. Finally, various concepts and techniques involving the use of dummy zones in resolving the regional definition problem are outlined.Keywords
