National Travel Survey, 2002-2020: Special Licence Access

The <I>National Travel Survey</I> (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 onwards). 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.<br> <br> Further information may be found on the gov.uk <a href="https://www.gov.uk/government/collections/national-travel-survey-statistics" title="National Travel Survey">National Travel Survey</a> webpage.<br> <br> <b>End-User Licence, Special Licence and Secure Access NTS data</b><br> The UK Data Archive holds three versions of the NTS:<ul><li>the End User Licence (EUL) versions (SNs 5340 and 6108) contain a comprehensive range of NTS data at Government Office Region geographic level and should be sufficient for most research needs.

<i>国民出行调查（National Travel Survey，NTS）</i>是一系列家庭调查项目，旨在定期提供最新的个人出行相关数据，并持续监测出行行为随时间的变化趋势。首次国民出行调查于1965年由英国交通部委托开展。后续分别于1972/73年、1975/76年、1978/79年及1985/86年开展了周期性调查（英国数据服务中心持有1972年起的最终用户许可数据，以及2002年起的特殊许可与安全访问数据）。自1988年7月起，国民出行调查转为连续调查模式，全年每月均开展实地调研工作，年度固定样本规模超过5000个家庭地址。2002年起，NTS样本量扩充至原规模的三倍，达到每年约15000个家庭地址。连续调查模式的优势在于，研究人员可同时识别出行行为的季节性波动、周期性规律与长期趋势变化。

国民出行调查主要服务于政府部门。英国交通部（Department for Transport，DfT）对该调查最核心的应用是将其作为关键交通模型的核心基准数据，这些模型对于国家及地方层面的交通方案提案、交通政策提案的评估与论证至关重要，同时也助力长期交通战略的制定与完善。NTS数据可用于构建统一规范的交通政策体系，由于该调查将出行行为与出行者个体绑定，因此可实现交通政策与特定人群的精准关联，并有效预测政策实施后的实际影响。本次调查详细记录了各类出行的核心信息：包括出行起点与终点、出行距离、出行目的及出行方式。NTS同时收集个人属性与社会经济信息，以区分不同人群的出行特征、出行习惯与出行频率。国民出行调查是目前唯一可提供步行等主题全国性统计数据的官方渠道，这类数据可为更多地方性出行研究提供权威背景支撑。

<b>最终用户许可版、特殊许可版与安全访问版NTS数据</b>

英国数据档案馆（UK Data Archive）共持有三个版本的NTS数据：
<ul>
<li>最终用户许可（End User Licence，EUL）版本（数据集编号SN 5340与SN 6108）包含政府办公区域地理层级下的全量NTS数据，可满足绝大多数学术研究需求。最终用户许可数据面向英国数据服务中心（UK Data Service）的注册用户开放（详情请参阅下文的管理与访问章节）。</li>
<li>特殊许可版本（数据集编号SN 7553与SN 7804）包含更精细化的出行相关数据（含出行事故记录）、人口统计与社会经济信息，其地理层级为地方当局/单一管理区。特殊许可数据的访问限制更为严格。</li>
<li>安全访问版本（数据集编号SN 7559）包含更细致的研究数据与邮编分区地理信息。安全访问数据的访问限制进一步提升，申请者需完成指定培训课程后方可申请。</li>
