The Department for Transport through the Bus Services Act 2017 requires requires bus operators and/or local transport authorities to openly publish information about bus routes and timetables, stopping places, fares and tickets, location information and more broadly the operation of bus services.
In July 2020 the statutory instrument to enable the DfT to mandate the provision of data was made:
https://www.legislation.gov.uk/uksi/2020/749/contents/made
RTIG have produced a quick guide to the dates and data formats required in the SI:
https://www.rtig.org.uk/system/files/documents/RTIGT040-2.0%20BODS%20SI%20Dates%20and%20Formats.pdf
The DfT have produced an implementation guide to support the statutory instrument:
Routes and Timetables
These need to be published in TransXChange format.
Version 1.1.A is the latest version of the profile documentation and can be downloaded at the bottom of this page.
The v1.1.A is an update to v1.1, the changes largely being updates to fix implementation issues and inclusion of information on the BODS validator. A track changes version of v1.1.A is provided with all changes since v1.1 identified and a summary of the changes in a slide deck are both available at the bottom of the page.
The schema documentation for TransXChange can be found here:
