SIRI v2.0 has been around since 2013. A lot has changed in the world of public transport technology in the subsequent 8 years.

To ensure that the SIRI standard meets current and foreseeable future requirements and known problems with the schema are fixed an update to the standard has been being worked on by the CEN SIRI working group for the last couple of years.

The measurement of vehicle occupancy for buses in real time is not something that was carried out regularly or, was in widespread use in the UK until the onset of the COVID-19 pandemic. Over the course of 2020, significant work was carried out and progress made, by suppliers and bus operators to introduce passenger counting solutions and present the information to passengers. 
Advice was provided in RTIGT039 Providing Vehicle Occupancy Data:- Data Interfaces in May 2020.

There is a lot of interest in vehicle loading and capacity so we have put together a short paper on the data exchange formats that exist now to enable you to provide vehicle occupancy data.

We are releasing this as a public document, for free, rather than just to members because of the interest in this topic in the wider transport community as we try to support the rebuilding of confidence in public transport following the COVID pandemic.
