This report was commissioned by the Department for Transport (DfT) to provide a comprehensive description of the structure and functionality of the National Transport Model (NMTv2R), as well as a detailed account of the model update and calibration process, in a single document that would be more accessible to external stakeholders.

This report is being published alongside an analytical review and a peer review.

About the National Transport Model

Our National Transport Model (NTM) – a multi-modal model of land-based transport in Great Britain – was first developed in 2001 and since then its data and assumptions have been updated regularly.

The NTM enables the DfT to estimate the impact of transport policies or forecasting assumptions on key travel indicators such as levels of traffic, congestion and vehicle emissions.
