| Abstract: | This report describes an application of continuous spatial models to freight movements in Greater London. Continuous spatial models are fitted to data on the densities of generation and attraction of the freight assuming that the density is dependent on the distance from the centre of the area. The fit is measured using regression analysis and the results are examined. The graphs of the densities against the distance from the centre suggest an exponential relationship, and Clark's model is fitted to the data. The model fits fairly well to the data on densities for most groups of commodities. The correlation between the density and the distance is stronger for attraction than for generation in most groups of commodities. |
