ACTIVITY ALLOCATION MODEL FOR NOTTINGHAMSHIRE-DERBYSHIRE SUBREGION

Batty M. (1970) An activity allocation model for the Nottinghamshire-Derbyshire subregion, Reg. Studies 4, 307–332. This paper outlines the development of a quantitative model, designed to explain the location of population and service employment in the Nottinghamshire-Derbyshire subregion. The model uses an economic base mechanism to derive population and service employment from basic employment, and spatial interaction submodels to locate the population and service employment in different zones of the subregion. To fit the parameters of the model, a two-stage calibration process is developed, incorporating a simple hill-climbing procedure which involves successively improving the values of the model's parameters until a best fit is reached. Assessments of the calibration process reveal certain structural weaknesses in the model. A description of the recursive projections made with the model is provided and demonstrated in relation to a hypothetical development strategy for the Nottinghamshire-Derbyshire...
