New roles for urban models: planning for the long term

Abstract

Governments and planners are increasingly exploring the challenges of urban development in the long runsay up to 50 years into the future. This paper investigates the ways in which urban models can be used to explore these challenges. Conventional testing through forecasting is not possible, intuitively obvious because of the uncertaintiestechnological and otherwise. The alternative is to seek a framework in which a range of future scenarios can be articulated and explored. It is shown that there are features of the original Lowry model that have been underexploited in the past that provide inspiration for this new challenge, particularly in his approach to land. It is shown that models will be valuable for scenario exploration in both comparative static and fully dynamic modes.

The role of open access in a changing academy: reflections on a new publishing paradigm

“…We remain committed to our mentored route for publication, led by the early career papers editors, but we encourage all scholars -from doctoral students to professors -to submit their work. We offer field-leading review times (currently averaging 35 days) and your work will sit alongside papers by such luminaries as Rob Kitchin (Kitchin, Lauriault, & McArdle, 2015), Alan Wilson (2016) , Ana Rita Cruz (2014), Kevin Ward (Ward et al, 2015) and Martin Jones (Beel, Jones, & Jones, 2016). One particularly appealing feature of RSRS is that we publish a variety of paper types, from our 'regional graphics' of two or three pages (including maps or graphics) to full-length more traditional manuscripts of around 8000 words.…”

Using the State Space of a BLV Retail Model to Analyse the Dynamics and Categorise Phase Transitions of Urban Development

“…Urban modelling has emerged from several different traditions [9,10], such as ecology and economics, including land use/land cover change models, land use and transportation models, system dynamics models and landscape dynamics models. The first models were static [11][12][13] and later dynamic models were developed mainly as a result of increasing computing power [4,14,15] Dynamic urban models are increasingly applied to explore possible future scenarios of urban development to achieve sustainability [16,17]. Dynamic urban models explore how urban development reaches a future state from a current one and so allows exploration of the reasons why phase transitions might occur.…”

The Future of Urban Modelling

“…But we then understand, both intuitively and technicallyin relation to nonlinear complex systemsthat they cannot deliver accurate long-run forecasts. What they can do for the longer run, is be used to explore the workings of alternative planning scenarios and in this context they can also be invaluable (see Wilson 2016c).…”
