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.

The report from the Traffic Light Priority Trigger Position File working group has now been published.

Existing work from RTIG: specifically, the documents T008 andT031, provide the specification and methodology for the transmission of data from public service vehicles, such as buses and trams, to traffic signals.

Version 1 of the BODS Public Transport Information Profile for TransXChange has been released.

There is no meaningful difference to the previous version that was circulated at the end of April. 
The only change is the removal of draft and uprating within the document to version 1. This has been done because of concerns that it should not be developed against because it was ‘draft’.
