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