This technical note details the process used to update the input parameters into the Wellington transport models (WTSM – Wellington Transport Strategy Model & WPTM – Wellington Public Transport Model), as part of their 2013 update. These parameters are used in WTSM to calculate the generalised costs of travel for all modes (light and heavy vehicles, public transport, and active modes) and therefore impact on the trip distribution, mode choice and route calculation components of the model. In WPTM, they inform the access mode choice, public transport mode choice, and route of public transport users.

The note also documents the methodology adopted to project these parameters in the future when forecasting with both models.
