National Trip End Model (NTEM)

The [freely available TEMPro software is required to view these datasets](https://www.gov.uk/government/publications/tempro-downloads). The National Trip End Model (NTEM) model forecasts the growth in trip origin-destinations (or productions-attractions) up to 2051 for use in transport modelling. The forecasts take into account national projections of: - population - employment - housing - car ownership - trip rates NTEM forecasts are subject to uncertainty, especially when disaggregated to local zones or travel modes. Before using the NTEM forecasts, the following DfT guidance should be reviewed: - [TAG Unit M-4 Forecasting and Uncertainty](https://www.gov.uk/government/publications/webtag-tag-unit-m4-forecasting-and-uncertainty-november-2014) - [NTEM Planning Guidance](https://assets.dft.gov.uk/tempro/version7.2/NTEM72-documentation.zip) that provides an overview of the forecasts and the input data used (available in the NTEM Documentation Download below). Further technical details are available in the [NTEM specification](https://www.gov.uk/government/publications/webtag-si-ntem-sub-models-july-2016). Queries regarding the NTEM forecasts should be sent to [Department for Transport](mailto:tempro@dft.gov.uk). To register to receive updates, email [TEMProMailingList@atkinsglobal.com](TEMProMailingList@atkinsglobal.com) to be added to the TEMPro distribution list.
