In 2000 Wellington Regional Council commissioned a major update of their regional transport model the Wellington Transport Strategy Model (WTSM). This multi-modal, emme/2-based model encompasses the entire Greater Wellington Region. The project commenced with an extensive survey programme (including household, intercept and count surveys) which, once these data had been processed, was followed by model recalibration, implementation and validation and the production of base forecasts. This paper describes two components of the model update: the car ownership and trip production model calibrations. As will become apparent in later sections, in order to ensure the most effective use of resources and time available, the authors carefully planned in advance and in detail each stage of the project. Wherever feasible, in principle decisions were made on the model specification in advance of calibration, based on knowledge of the local context and experience of models nationally and internationally.
