The 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 in 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. For example, the 2020 survey estimates are reported as a single year instead of the usual three years combined and the results are not directly comparable to those from previous years.
