Standards

The Bus services around the Christmas and New Year period will often operate differently to normal weeks. 

The data for use in services such as the Department for Transport Bus Open Data Service , Traveline, journey planners, real time systems and mobile phone apps all need to be updated to reflect the changed operation. 

This advice deals with how to prepare data for the BODS service to ensure that it is correct for the Christmas and New Year 2021 holiday period. 

We have discussed for a couple of years the impending update to SIRI.

The updates have now reach the formal consultation stage of the CEN standards process.

During this stage the documents are available for review to identify editing errors, inconsistencies and similar.

The latest TransXChange v2.4 Public Transport Information profile has been released.

The current version is now 1.1.A, updated from v 1.1 on 5 July 2021.
Version 1.1.A is the version that the Bus Open Data Service will be using.

The v1.1.A is an update to v1.1, the changes largely being updates to fix implementation issues and inclusion of information on the BODS validator.

A track changes version and slide deck of the differences is available on the PTIC website:

SIRI v2.0 has been around since 2013. A lot has changed in the world of public transport technology in the subsequent 8 years.

To ensure that the SIRI standard meets current and foreseeable future requirements and known problems with the schema are fixed an update to the standard has been being worked on by the CEN SIRI working group for the last couple of years.

We are running with the DfT another series of workshops to explore different aspects of bus stops and data as part of the re-development work taking place on NaPTAN systems.

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

The guide to SIRI has been updated. The previous version had not been updated for many years and was out of date.

This report outlines the background to SIRI and describes the different functional services provided as well as addressing how SIRI can be used in procurements.
