Using the flexibility provided by the Datafunc software, Peter generalised the work done in implementing the BITFEM model so that it could be used in other areas. The generalised system, the Integrated Transport Forecasting and Evaluation Model (ITFEM) was applied to the Gold Coast and the Sunshine Coast, as well as to a model combining all of South East Queensland. The flexibility afforded by ITFEM enabled the models to be customised to each local area, but still be compatible with the other models, and running on a single set of modelling scripts.
