DATEX II supporting harmonised message for Safety-Related Traffic Information

One of the EU delegated regulations complementing the ITS Directive 2010/40/EU focuses on safety-related traffic information for the end user. Last February, thanks to the collaboration of TISACar2Car Communication ConsortiumData for Road Safety and DATEX II, the third revision of the terms used in traffic communication protocols was published.

The document provides a subset of DATEX II situations, DENM and TPEG2-TEC causes and TMC events, which will be defined and declared as the message sets to be used for safety-related messages. In addition, for the selected message sets, a correlation between the four traffic communication protocol standards DATEX II, DENM, TPEG and TMC is defined.

As new features, this new revision includes 10 new events based on a survey conducted to record events that are classified as safety-related messages, as well as new definitions and recommendations to facilitate the expression of these events in the main usage standards.

The provision of accurate and quality information to road users on traffic-related incidents is a key factor on which all European operators agree. Achieving high values in the quality and accuracy of the information provided is possible thanks to technical innovations and improved detection and warning services.

Bard de Vries, Chairman of the DATEX II Technical Group and Chairman of the SRTI Working Group noted that “The DATEX II community considers it a fundamental responsibility to ensure that the provision of security related data is supported by the interdependent data standards used. Harmonization and interoperability between the exchange chain is fundamental to reliable information provision as such. With this version 3 document an important step has been taken: new stakeholder communities have been involved and relevant future harmonization topics have already been identified. It is great to have a coalition of key players joining forces and contributing greatly to road safety for all.”

The SRTI profile in EU harmonized DATEX II that allows users to customize their implementations to their own requirements while maintaining interoperability on common parts with other users is available  here.
