Abstract: Integrated land use transportation models simulate the behavior of the spatial economic system and the interactions between the transportation system and the rest of the economic system. The essential elements of these models are explicit treatment of space in economic production and consumption behavior, both the space that is the physical areas that contain production processes and the space that separates different production locations and gives rise to the demand for travel and transport. They put travel within an economic context, and thus facilitate simulation of the impacts of transportation policy and planning actions and transportation conditions on the wider economic system. As such, integrated models can be used address complex policy questions that more limited transportation models cannot address, or cannot address well.

This seminar will set out the basic scope and form of integrated models and discusses several of the key advantages they provide for planning. Experiences gained in the practical applications of the Oregon SWIM and Sacramento MEPLAN and PECAS integrated models will be described. These experiences will be used to illustrate the added benefits arising with such models in terms of more efficient land use forecasting, more complete analysis of cumulative and indirect impacts and more holistic consideration of policy in general, more evaluation of economic impacts with greater relevance, and more effective communication among those concerned with transportation and land use decision-making. This will lead to a more general finding that integrated models can contribute usefully in practical contexts by informing actual policy questions and providing measures to help policy-makers make difficult trade-off decisions.

Speaker Bio: Dr JD (‘Doug’) Hunt is a Professor of Transportation Engineering and Planning in the Department of Civil Engineering at the University of Calgary. He has been at the University of Calgary since 1991. Before that, Doug was a professor at the University of Alberta and he has also worked in industry in Canada, the United States and the United Kingdom. Doug has a BSc from the University of Alberta and a PhD from Cambridge University. At the University of Calgary, Doug teaches courses in transportation, urban and regional systems, modelling and statistical analysis. His research interests concern the human element in transportation and spatial economic systems – focusing particularly on the mathematical modelling and computer-based simulation of these systems and the impact of these systems on the larger economy. A major thrust of his work is the practical application of advanced modelling techniques. He is also active in specialized consulting to governments in the development and application of advanced modelling techniques. Doug enjoys a strong international reputation, having developed the PECAS modelling system, helped develop the MEPLAN modelling system, and worked on transport and/or transport and land use models of London and South-East England, Naples, Barcelona, Madrid, Dublin, Dortmund, San Diego, San Francisco, Phoenix, Detroit, Baltimore, Oregon, Ohio, Sweden, Alsace, Central Chile, Edmonton and Calgary – to name just some. He also spent 4 years as special advisor to British Rail concerning the Channel Tunnel Rail Link patronage forecasting.
