The Travel Survey for Northern Ireland (TSNI) collects information on how and why people travel within Northern Ireland.


The TSNI started in 1999 and is based on the National Travel Survey run by the Department for Transport. Three years of data need to be combined to ensure the analysis carried out is robust.  

UPDATE: The delay in receiving the TSNI 2017-2019 datasets and investigating the methodology changes in 2020 due to COVID-19 continues to have a knock on effect on the usual publication timetable of the TSNI reports.  The 2020 Headline Report was published in March 2022.  The 2020 In-depth Report is planned for publication in Summer 2022.  Further updates will be announced here.

User engagement

Analysis, Statistics and Research Branch (ASRB) have carried out various user engagement activities. The latest was a user consultation exercise in relation to the content and format of the 'Travel Survey for Northern Ireland’ (TSNI) headline and in-depth reports. The consultation period ran from 7 May 2019 to 2 July 2019.


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. Short TSNI factsheets with infographics highlighting specific topics have been produced since 2014-2016.
