Perhaps the most common enquiry posed to the TLUMIP team and ODOT staff is for pointers on learning about integrated land use-transport models. Fortunately, there is an abundance of literature on the topic. The bad news is that it's overwhelming in some respects. This section summarizes some of the papers, reports, and projects that we've found helpful.

For beginners

We've found a collection of excellent resources that provide an overview on integrated land use-transport modeling. Unfortunately, they're not all assembled in one place. One prerequisite is a thorough understanding of discrete choice models, as logit models are employed in almost all of the current models out there. The excellent Self Instructing Course in Mode Choice Modeling: Multinomial and Nested Logit Models by Frank Koppelman and Chandra Bhat has been recently revised, and is available online. There is also a chapter on the topic in de la Barra's textbook (see below). The current definitive book on the subject is Applied Choice Analysis: A Primer (2005, available in both hardcover and paperback from Amazon) by David Hensher, John Rose and William Greene. Ken Train also has his book, Discrete Choice Models with Simulation, and accompanying online course, available on his webpage. We recommend that you approach this material in the order given, as the material gets progressively more mathematically and theoretically rigorous.

A good overview of the theoretical underpinnings of integrated land use-transport modeling can be found in Tomas de la Barra's textbook, Integrated land use and transport modelling: Decision chains and hierarchies. It's available from Amazon. Tomas has a clear and engaging writing style, making the book a nice read. It's slanted toward aggregate equilibrium models but the underlying concepts will transfer well to any approach to this type of modeling. An excellent overview of currently operational models by Michael Wegener, published as a chapter in Transport Geography and Spatial Systems (2004, available from Amazon) can be downloaded here. It's a nice update to Michael's often cited "Operational urban models: State of the art" that appeared in the Journal of the American Planning Association in 1994. The list of essential readings continues with:

These reviews highlight the range of operational models out there, but do not delve deeply into dynamic disequilibrium (DD) models, which represent a significant departure from the earlier aggregate equilibrium models. We believe both approaches are valid; the choice between them should depend upon the type of questions that will be posed to the model, data availability, resources (time and people) available for development and application, and the like. That said, an introduction to land use-transport modeling will not be complete without a solid foundation in the newer DD models, most of which are implemented in a microsimulation framework. Recommended readings include:

• "Microsimulation of urban land use" by Carsten Schürmann, Rolf Moeckel and Michael Wegener, which describes the ILUMASS model. The paper is available online.
• "Introduction to urban simulation: Design and development of operational models" by Paul Waddell and Gudmundur Ulfarsson, a chapter in the Handbook in Transport series, describes UrbanSim. A downloadable copy is available from Paul's website.
• A detailed description of a model called SVERIGE is chronicled in a 1999 conference paper by Coomaren Vencatasawmy et al, "Building a spatial microsimulation model."

Another paper we recommended, but that is harder to chase down outside of academia, is:

These resources are but the tip of the iceberg of the literature in this field. The many references cited in these papers and books will give the serious reader ample material to pursue.
