These are tasks designed to confirm the key decisions on model structure and to clear up particularly uncertain aspects of the specification. In many cases, the issues will relate to how to address specific, new customer objectives in the model. The following tasks relate to the Wellington model development.
  1. Review of performance of present transport model: to ensure that we understand its weaknesses and have plans for overcoming them in the new model
  2. Initial transport survey tabulations: designed to confirm the model segmentation decisions
  3. Analysis of parking data: to firm up on the treatment of parking in the transport model
  4. Specification of generalised cost, on which the transport model will be based. An example of the outcomes is here
  5. Retail destination analysis: develop the treatment of different types of retail destinations in the transport model
  6. Commercial vehicle travel and vehicle types: confirm the approach to commercial travel and the different vehicle types
  7. Education modelling & school buses: review the modelling of education trips and the representation of school buses
  8. Car passenger modelling and escort trips: determine the treatment of escorts in the transport model.
  9. Weekend travel model: design the weekend travel modelling methodology.
  10. Road pricing/tolling in the transport model: review how these policies are to be modelled
  11. Commercial vehicle modelling: specify this aspect of the transport model
  12. Use of intercept matrix data: consider how this travel data is to be used in the transport model calibration
  13. Park-and-ride at rail stations: consider whether these trips can be separated out in the transport model
  14. Ports and airports: specify how major generators of 'external' trips such as airports and ports will be modelled
  15. Project models: discusses the role of the strategic transport model in providing information to project models. An example of the outcomes is here.
  16. Model calibration inputs: sets out the input data sets required for transport model calibration
