This short paper reviews the range of planning issues that are currently being addressed in Britain and considers how the nature of these issues and the ways in which choices are being assessed impact the modeling approaches being adopted, in particular, by the author's own consultancy practice. The paper briefly outlines current developments in governance and analytical requirements; implications of trends toward more detailed (and more time-consuming) transport modeling; and the role of microsimulation in both research and planning practice. It concludes primarily that the practicality of model operation, particularly in terms of model run times, is of critical importance, and in many cases, determines whether major planning decisions are made on the basis of formal analysis rooted, albeit indirectly, in research, or without such a basis at all. A secondary conclusion relates to the possible use of output from detailed microsimulation models as a basis for calibrating aggregate models.

"The focus of this book is the modeling of the location of economic activities, measured in terms of employment, in land-use and transportation systems. These measures are key inputs to models at intra-urban scales of the flows of persons and goods for both urban and transport planning. The models described here are either components of comprehensive models or specialist studies. Economic activities can be defined in terms of jobs or private-sector firms and public service organisations. Different levels of aggregation are used both in terms of organisational and geographical dimensions. In the case of firms and public organizations, a distinction can be made between the organizations themselves and corresponding establishments. For urban simulation models, it is the location of establishments that is important. At the more coarse levels of aggregation that are usually used in comprehensive models, firms and organizations are aggregated into sectors."--Provided by publisher

The effective planning of residential location choices is one of the great challenges of contemporary societies and requires forecasting capabilities and the consideration of complex interdependencies which can only be handled by complex computer models. This book presents a range of approaches used to model residential locations within the context of developing land-use and transport models. These approaches illustrate the range of choices that modellers have to make in order to represent residential choice behaviour. The models presented in this book represent the state-of-the-art and are valuable both as key building blocks for general urban models, and as representative examples of complexity science.
