The future of urban modelling is viewed first against a background of its fifty-decade history. The effects of increased computing power and the availability of new data sources are explored, particularly through a wider range of scales and applications – illustrated by global scales and...
Prior weighted entropy functions compensating for the arbitrary partitioning by the zoning system of the origin and destination quantities in entropy maximising models of spatial interaction are presented and justified. This type of prior weighting is essential if the dual variables derived from...
This paper overviews the different approaches being used by regional planning agencies to estimate the spatial patterns of freight flows within the United States. The narrative moves from a discussion of current modeling practice to consider how on-going research efforts are moving this practice...
In this paper, we investigate the effects of scale and zone configuration on migration indicators and spatial interaction model parameters using a software system known as the IMAGE Studio. Internal migration flows in the United Kingdom and the local authority districts between which they move...
Spatial interaction models have seen extensive use in public and private sector planning over the past 50 years. This paper reviews a number of facets of the application of these models. In particular we focus on developments in testing how well the models work in a number of different contexts...
A theoretical model was developed using the entropy approach to cope with the random component of the utility function to find that the spatial accessibility improves as the provider capacity increases or the opportunity cost of traveling to and from health provider decreases. The Kernel Density...
