Vehicle Occupancy in SIRI 2.1

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.

Traffic Light Priority Trigger Position File Format Schema

In recent years, there has been renewed interest in the digital provision of priority to public transport at signalised junctions. 

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. These provide technical frameworks to provide priority for public transport vehicles at signalised junctions in an interoperable manner.

Real Time Information Exchange Using the SIRI Standard

On behalf of the UK, RTIG has contributed to the definition of a CEN standard to define a “Service Interface for Real-time Information” (SIRI). It is intended to be used to exchange information between servers containing real-time public transport vehicle or journey time data.

These include the control centres of transport operators and information systems that utilise real-time vehicle information, for example, to deliver services such as travel information.
