Within the context of transport statistics routine revisions of statistical data concern:

- revision of the published quarterly data upon receiving additional or revised information from respondents.

  • Example: Data of the Road Transport Survey can be received and processed for any surveyed week throughout the year. It means that even at the end of the year data can be entered for the 3rd week of the year. Data are collected and data revision takes place by quarter – at the end of the second quarter for the first quarter, at the end of the third quarter for the first and second quarter and when processing the fourth quarter data - for all three previous quarters.
