Transport Statistics Great Britain (TSGB) is the department’s main statistical compendium publication. It describes the major statistical trends in the British transport sector, and is normally published in December each year.
For much of the contents of TSGB, topic-specific DfT statistical publications during the year provide the first release of data, which is consolidated into TSGB at a later date. The online versions of TSGB tables are updated throughout the year as new data becomes available. However, each online edition of TSGB includes a ZIP archive file containing ‘snapshots’ of all tables taken at the point of TSGB’s release.
