description: The &lt;i&gt;National Travel Survey&lt;/i&gt; (NTS) is a series of household surveys designed to provide regular, up-to-date data on personal travel and monitor changes in travel behaviour over time. The first NTS was commissioned by the Ministry of Transport in 1965. Further periodic surveys were carried out in 1972/73, 1975/76, 1978/79 and 1985/86 (the UK Data Service holds End User Licence data from 1972 onwards and Special Licence and Secure Access data from 2002). Since July 1988 the NTS has been carried out as a continuous survey with field work being carried out in every month of the year, and an annual set sample of over 5,000 addresses. From 2002, the NTS sample was increased approximately threefold, to approximately 15,000 per year. The advantage of the continuous study is that users will be able to discern seasonal and cyclical movements as well as trend changes over time. The NTS is carried out primarily for the purposes of government. The most fundamental use of the National Travel Survey within the Department for Transport (DfT) is as core base data for key transport models. These are critical to the assessment and appraisal of transport scheme proposals (national and local), transport policy proposals, and contribute to the development of our long-term strategy. The NTS data is used to develop consistent sets of transport policies. Because it relates travel to travellers, it makes it possible to relate policies to people and to predict their impact. The survey provides detailed information on different types of travel: where people travel from and to, distance, purpose and mode. The NTS records personal and socio-economic information to distinguish between different types of people, and the differences in the way they travel and how often they do so. The NTS is the only source of national information on subjects such as walking which provide a context for the results of more local studies.&lt;br&gt; &lt;br&gt; Further information may be found on the gov.uk &lt;a href="https://www.gov.uk/government/collections/national-travel-survey-statistics" title="National Travel Survey"&gt;National Travel Survey&lt;/a&gt; web page.&lt;br&gt; &lt;br&gt; &lt;b&gt;End-User Licence, Special Licence and Secure Access NTS data&lt;/b&gt;&lt;br&gt; The UK Data Archive also holds End User Licence (EUL) NTS data from 1972 onwards (see SNs 2852, 2853, 2855, 3288, 4108, 4583-4585, 6108 and 5340) and Special Licence (SL) NTS data from 1995 onwards (SNs 7804 and 7553). The EUL versions contain a comprehensive range of NTS data at Government Office Region geographic level and should be sufficient for most research needs. The SL versions contain more detailed travel (including accidents), demographic and socio-economic data, and the geographic level is Local Authority/Unitary Authority. These data are subject to more restricted access conditions than EUL. The Secure Access version contains more detailed information and postcode sector geographies. Secure Access data are subject to further restricted access conditions, including the completion of a training course. For full details of the differences between the EUL, SL and Secure Access NTS, see the document '7559_nts_table_structures.xls' in the documentation. Users should always check whether the EUL and SL versions are suitable for their research needs before considering making an application for the Secure Access version.&lt;br&gt; &lt;br&gt; For the seventh edition (October 2021), the data files were replaced with new versions covering 2002-2020. The documentation has been updated accordingly. &lt;br&gt;&lt;br&gt;
