Printedonacid-freepaper SpringerispartofSpringerScience+BusinessMedia(www.springer.com) Foreword A generation or more ago when land use transport models were first being developed, the focus was on how different models compared with one another in technical and theoretical terms. There was a concern for dynamics, for interaction and for calibration and validation, but less so for how such models might be interfaced with wider planning processes and the stakeholders that operate such systemsandareindeedinfluencedbytheplansthatemergedfromthem.Thestate of the art then consisted of comparative studies of cross-sectional comprehensive spatial interaction model applications catalogued, for example, in the ISGLUTI Project – the International Study Group on Land Use Transport Interaction – and reportedinthebookbyWebster,BlyandPaulley(1988).Thedominantfocuswas verymuchintermsofthetechnicalperformanceofmodelsratherthantheirusein planningorpolicy-making. As our experience of these models grew and evolved, this focus began to shift tothecontextinwhichmodelswerebestused.Ontotheagendacameideasabout thevarioustoolsthathadbeendevelopedtoinformhowwemightbestmakegood plans, and how these could be stitched together into coherent planning methods.

Until now that is, because this book represents the first such chronology of how a suite of land-use modelling tools called LUMOS – Land Use MOdelling System – which is centred on the Land Use Scanner model with another model Environment Explorer being sometimes v vi Foreword used in parallel, is being fashioned to examine a wide array of different planning issues ranging from climate change to ways of reducing energy use in transport.

Before the various contributions move onto applications and extensions of the models, van Schrojenstein Lantman, Verburg, Bregt, and Geertman provide an interesting and informative review of land-use models ranging from land cover to cellularautomataandthencetoagentbasedmodels.Theyreviewsixgenerictypes inmoredetailincludingGEOMOD2whichislandcoverbased,SLEUTHwhichis acellularautomatalanddevelopmentmodel,UrbanSimwhichisprobablythebest exampleofacontemporarylandusetransportmodelbasedondiscretechoicetheory but also embodying fine scale spatial grain with an agent-based focus, IMAGE an ecological–environmental framework to explore the long-term dynamics of global Foreword vii change,CORMASamulti-agentframeworksimulatingnaturalresourcesallocation, and ILUMASS a micro-simulation model of urban land use.

This book is a timely and important contribution to ways in which we might use models in planning, models in practice, and how we might best use them to inform the dialogue between professionals and decision-makers.

This book redresses this balance for it contains a wealth of experience that is not available anywhere else.

Joshua Epstein (2008) in a fascinating essay entitled Why Model? makes the point ‘The choice, then, is not whether to build models;it’swhethertobuildexplicitones.Inexplicitmodels,assumptionsarelaid out in detail, so we can study exactly what they entail’.

Urban land use and transport interaction: Policiesandmodels.Farnborough,Hants:Gower. Preface Land-use modelling has been firmly established in Dutch planning practice in the past 10 years. The Land Use MOdelling System (LUMOS) toolbox, managed by PBL Netherlands Environmental Assessment Agency, has made this development possible. The development of this toolbox started in 1996 and builds on the cooperation of public research organisations such as PBL and the Agricultural Economics Research Institute (LEI), academic institutes (VU UniversityAmsterdam)andcommercialITcompanies(GeodanandObjectVision). Theongoingmodeldevelopmentprocessisuniqueinthesensethatitreflectsalmost 15yearsofcontinuousinteractionbetweenplanners,researchersandITspecialists. This book gives an overview of the wealth of recent applications and developmentsoftheLUMOStoolbox.Itcontainscontributionsofthemanypartners that are active in applying and developing the toolbox and focuses specifically on the Land Use Scanner model that was applied in a wide range of policy-related studies in the past years. In addition to being employed for trend extrapolation, scenario studies and optimisation at the national level, the model has also been frequently used at the lower, regional scale level as is demonstrated in the various regional cases that are included in the book.
