In addition, data on air traffic and available airplane seats are collected. This is based on the data collected under European Parliament and Council Regulation 437/2003 of 27 February 2003. Some additional information on air transport infrastructure and fleet are collected on voluntary basis using the annual questionnaire.

In addition, one table in the regional transport section is based on another voluntary data collection (the "REGWeb" questionnaire); it contains information on railway infrastructure (length of railway lines – total, electrified and with two or more tracks) by NUTS 2 region.

The data collections on rail accidents are based only on accident data received from the European Union Agency for Railways as since 2016 they were no longer required by the regulation.

Information on road accidents (persons injured or killed) is derived from the EU central database (CADaS - Common Accident Data Set). Figures on air and maritime transport at regional level come directly from the respective transport data collection. Regional statistics are disseminated at NUTS 0 (country), NUTS 1 and NUTS 2 level.
