Travel Survey (TSNI)

The Travel Survey for Northern Ireland (TSNI) collects information on how and why people travel within Northern Ireland.  Headline, technical and in-depth reports are published annually.


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 In-depth Report was published in September 2022.  The 2021 Headline Report is planned for publication in March 2023.  Further updates will be announced here.


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. 

User engagement

Analysis, Statistics and Research Branch (ASRB) have carried out various user engagement activities, including a user consultation exercise in relation to the content and format of the TSNI reports. An outcome report of this user consultation and a statement of user needs have been published.
