The Travel Survey for Northern Ireland (TSNI) collects information on how and why people travel within Northern Ireland. The technical report is produced annually and contains information on survey methodology as well as the survey questionnaire. There were significant changes to the survey methodology from April 2020 because of the COVID-19 pandemic and these are detailed in this report along with the consequent changes to the data analysis and reporting.
