The thesis of this book is that there are one set of equations that
can define any trip between an origin and destination. The idea
originally came from work that I did when applying the hydrodynamic
analogy to study congested traffic flows in 1981. However, I was
disappointed to find out that much of the mathematical work had
already been done decades earlier. When I looked for a new
application, I realised that shopping centre demand could be like a
longitudinal wave, governed by centre opening and closing times.
Further, a solution to the differential equation was the gravity
model and this suggested that time was somehow part of distance
decay. This was published in 1985 and represented a different
approach to spatial interaction modelling. The next step was to
translate the abstract theory into something that could be tested
empirically. To this end, I am grateful to my Ph. D supervisor,
Professor Barry Garner who taught me that it is not sufficient just
to have a theoretical model. This book is an outcome of this
on-going quest to look at how the evolution of the model performs
against real world data. This is a far more difficult process than
numerical simulations, but the results have been more valuable to
policy formulation, and closer to what I think is spatial science.
The testing and application of the model required the compilation
of shopping centre surveys and an Internet data set.
