The TSNI started in 1999 and is based on the National Travel Survey run by the Department for Transport. Three years of data are normally combined to ensure the analysis carried out is robust. This ensures a wide range range of analysis can be carried out. Where it is established that there is a large enough achieved sample, it is possible to report limited information for single years.
Three TSNI reports are produced annually. Technical reports (survey methodology and questionnaire) and in-depth reports (detailed results) are available from 1999-2001. Headline reports (key results) have been published since 2007-2009.
- The headline report and the technical report have been published for 2021.
- The latest full set of publications available are for 2020, 2017-2019 and 2016-2018.
- Previous publications (1999-2001 to 2015-2017) are also available.
- Short TSNI factsheets with infographics highlighting specific topics have been produced from 2014-2016 to 2016-2018.
All previous publications (1999-2001 to 2015-2017) are available to view.
