Technical Documents

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.

This report specifically addresses one key customer challenge - the presentation of information about a journey for which a bus then does not appear at the customer location, often referred to as ghost buses.

It is an extract from the document RTIGT041 Accuracy and Quality of real Time Predictions and provides guidance on the causes of Ghost Buses.

There are a bewildering range of displays on offer from suppliers - from LED to TFT, powered by mains, battery and solar. With the climate emergency and environmental concerns high in people’s minds, the impact of our choices of technology needs to be considered more than ever.

Purchasing and environmental teams are increasingly expecting questions to be asked whenever equipment is purchased.

This document has been produced to help understand how customer information systems can better be managed during the current driver shortage. 
This document identifies a number of actions that may help the industry longer term with managing high volumes of short notice changes and cancellations. 

In 2017, through the Bus Services Act, the government introduced powers to require the provision of audible and visible information on local bus services throughout Great Britain.

When enacted, this will require bus operators to equip their vehicles with display screens to provide next stop information and audio systems to announce the information - using both speakers and induction loops.

This paper brings together the findings of an RTIG research project carried out in 2021 into Low Bridge strikes.

This has been a problem for high-sided vehicles such as HGVs and buses for a long time and can be very costly - both in economic and human terms.

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.

This document has been produced by RTIG as a specification for a set of messages that can be communicated between a bus management centre and a traffic control centre, in order to request and grant priority for buses at traffic signals.

This document has been produced by RTIG as a specification for a set of messages that can be communicated between bus-mounted devices and office-based systems, using a digital open protocol.

This document details the specification and methodology for the transmission of data from public service vehicles, such as buses and trams, to traffic signals and electronic public transport real time information displays.
