Originally published in 1973, this book reports experiments in the
modelling of freight flows in Great Britain, on the basis of 78
origin-destination zones covering the entire country. Its central
purpose is to establish whether gravity model or linear programming
approaches provide the most appropriate way of describing the
existing spatial distribution of freight volumes and hence of
predicting future flows, given possible allocations of population.
Linear programming appears to be the msot useful way to approach
freight modelling on this scale. The model outputs allow the
authors to probe the problem of regional comparative advantage in
terms of the volume of transport inputs. Although there is some
association with the accessibility of regions, it is not true that
the peripheral areas are at a serious disadvantage. Furthermore,
evidence on the structure of transport costs indicates that
movement costs are a surprisingly low proportion of total transport
costs - thus further reducing the effects of location. The study
concludes with a review of the lines along which work might
proceed.
