Brings together all documents relating to TEMPro (Trip End Model Presentation Program).
The National Trip End Model (NTEM) forecasts and the TEMPro (Trip End Model Presentation Program) software are used for transport planning purposes. The forecasts include:
- households by car ownership
- trip ends
- simple traffic growth factors
based on data from the National Transport Model (NTM). The data and software are available for free, for anyone to use.
Users of NTEM data and TEMPro software are advised to register. The NTEM datasets are updated periodically with updates to data sources, whilst the software is updated from time to time. Registration allows us to inform users when the planning data or software is updated. To register, please email TTWDsoftware@atkinsglobal.com with your name, organisation, email address and telephone number with “ADD” in the subject line.
Background to TEMPro
Forecasts such as NTEM datasets are always subject to uncertainty. For guidance on how to manage uncertainty in transport forecasts, please see TAG unit M4 forecasting and uncertainty.
The current definitive version of the dataset is NTEM 6.2, which should be used in conjunction with the current version of the software, TEMPro 6.2. The previous version of the dataset, NTEM 5.4, is still available to check work carried out since 2008. Registered users will be informed when updates are available.
Earlier versions of the NTEM dataset and TEMPro software are available on request in order to verify work that was done before NTEM 5.4 was released in 2008. However, these are no longer fully supported by the department. Please email email@example.com if you require earlier versions.
TEMPro is designed to allow detailed analysis of pre-processed data from the NTEM. The pre-processed data is itself the output from a series of models developed and run by DfT’s Transport Appraisal and Strategic Modelling (TASM) division. TEMPro can also be used to provide summaries of traffic growth using data from the National Transport Model (NTM).
TEMPro provides data on trips:
- on foot
- by bicycle
- by motor vehicle (both as a driver and passenger)
- by rail
- by bus
Users should note, however, that TEMPro trip ends by mode are based on average rates over a wide area and do not necessarily take into account the accessibility of each zone by each transport mode.
Analysis of the data can be any combination of:
- geographical area (down to a ‘zonal’ level of resolution, with each local authority area divided into several zones)
- transport mode
- time of day of travel
- purpose of journey
- years of interest (from 2001 to 2041)
- type of analysis (trips in terms of producing/attracting, origin/destination or car ownership)
Results are presented either in terms of growth over the selected period or in terms of the raw trip-end data.
The model also allows the underlying planning data used in generating the pre-processed data to be viewed and alternative planning assumptions to be entered to see what impact these would have on trip-end data.
The system has a full context-sensitive help system built into it.
The TEMPro 6.2 software can be downloaded from this site, as can the NTEM datasets. The data is divided by region, Scotland and Wales and the NTEM datasets can be downloaded and used as required - users need only download those regions they wish to use. TASM will be updating these datasets from time to time and will post the latest version of each regional data file on the site. NTEM datasets are released in draft for at least 3 months before becoming definitive. Registered users will be contacted by email to tell them when the software or data are updated or when the status of the dataset changes from draft to definitive. Users may download and use the program and data free of charge but the ownership and intellectual property rights to TEMPro software and the NTEM datasets rests with the Secretary of State for Transport.
