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.

Both the standards within these documents rely on messages being sent to traffic signal systems at predefined locations, or trigger locations; but neither standard defines the structure through which trigger location data can be shared. 

This document sets out to address this gap through the definition of a standard format for the sharing of trigger location data.
