The National Transport Model
The National Transport Model (NTM) provides a systematic means of comparing the national consequences of alternative national transport policies or widely-applied local transport policies, against a range of background scenarios which take into account the major factors affecting future patterns of travel.
Updating national car ownership model
The update to the Department’s NATCOP model has been a recalibration to a 2001 base, making use of up-to-date data sources of planning data and household income. The model also allows output of custom income segmentation. This will inform future versions of TEMPRO, which feed into the NTM.
