Results

During the Symposium, a few key themes on integrating land use and transport models came up in several presentations and dominated the discussion. Model runtime, the benefits of microsimulation and the need to integrate models at different scales and from different domains were the most frequently raised topics for integrated modeling.

Key conclusions include

  1. The case for simpler models (see also note by Keith Lawton)
  2. A framework for multi-scale models (Led by Michael Wegener)
  3. The Oregon TLUMIP retrospective (Led by Rick Donnelly)
  4. The value of integrating other models, such as pedestrian modeling, DTA, health models, environmental impact models, etc. (Led by Kelly Clifton)
  5. The need for integrated models to understand the impacts of climate change and develop strategies to mitigate and adopt (Led by Alistair Ford)
  6. Integrated modeling in the UK: Practical usability of integrated models (Led by David Simmonds)
  7. A synthesis of the symposium and key themes and issues that emerged (Led by Rolf Moeckel)

To document findings, articles were published in The Journal of Transport and Land Use (JTLU) to share the outcome with the larger modeling community. The following papers were developed directly from the findings of this symposium:
