Developments in the chain
From traffic service provider to data and information provider
ITS Directive + Delegated Act
Open data
From single modallity information services to multi modal information services
From single roadnetwork operator information to heterogeneous roadnetwork information services
Urge to cooperate across borders shifts from motorway operator borders to roadnetworkoperator
borders
The will to cooperate requires standardisation of interfaces on the border

Each actor has to maintain receiving
asynchronous different interfaces in terms
of:
Information model
Location referencing standards
8 systems 28 interfaces

It could be worse
56 different interface implementations
Risk of
Misinterpretation
Loss of information
Very complex system environments
High maintenance costs
High risk of failure
1 operator 7 outgoing and 7 incoming all different Resulting in

What is DATEX II in functional terms
The reflection of the will to cooperate
A well functioning platform that transforms this into deployable
standards
Coming from NRA motorway operators
Open for all stakeholders

DATEX II 4 dummies
E- language for traffic and travel information to exchange
language and presentation method independent
Focus on exchange between TCC – TCC/TIC and TIC-SP
Like a spoken language: grammar and phrasebook
Maintained by stakeholder community
Stable parts are standardised
Local additions are facilitated

What does DATEX II do?
It is like communication via a letter:
![Page 10: WHAT CAN DATEX II DO FOR YOU? - cvut.cz · PowerPoint-presentatie Author: Bard de Vries Created Date: 6/4/2014 4:56:22 PM](https://reader035.vdocument.in/reader035/viewer/2022071605/6141490a6d7bf66e09136db7/html5/thumbnails/10.jpg)

What is DATEX II in this perspective?
DATEX II = language and paper
Postal system: uses standard IT One envelope type is developed (XML)One transport type is defined in two flavoursPull (webservices and simple http)Push
Content is independent from postal system
If required other delivery methods can be developed
![Page 11: WHAT CAN DATEX II DO FOR YOU? - cvut.cz · PowerPoint-presentatie Author: Bard de Vries Created Date: 6/4/2014 4:56:22 PM](https://reader035.vdocument.in/reader035/viewer/2022071605/6141490a6d7bf66e09136db7/html5/thumbnails/11.jpg)

The content part of DATEX II
DATEX II covers:
Roadworks
Traffic Management actions (manual and automated)
Congestion information
Parking information
Weather data (rain, snow, wind, dust etc.)
Detector data per second or per vehicle
Traveltimes
VMS settings
Involved cars in accidents and characteristics of injured
It is a language: simply providing phrasebook and grammar is not sufficient

What do you have to do?
Step by step approach
Start with defining your information service in functional
terms:With who are you going to exchange
Agree on the language
What is the Roadnetwork
What Information on that Roadnetwork
Do you really have the information?
![Page 13: WHAT CAN DATEX II DO FOR YOU? - cvut.cz · PowerPoint-presentatie Author: Bard de Vries Created Date: 6/4/2014 4:56:22 PM](https://reader035.vdocument.in/reader035/viewer/2022071605/6141490a6d7bf66e09136db7/html5/thumbnails/13.jpg)
DATEX II User Forum – Prague – 19 20 May 2014
The next steps
Determine the operational level of the service
Operations supported
Timeliness requirements
Strong coupled or loose
Determine the locationreferencing method used
TMC, Agora-C, linear, Open-LR, TPEG

DATEX II is a sound basis
CEN Standardised
Clear framework for the traffic information language
Maintained by stakeholders themselves with clear procedures
Clear and (never)complete information model
Open method to adapt new requirements
Clear split between content and technology
Uses standard IT solutions for non traffic specific requirements
![Page 15: WHAT CAN DATEX II DO FOR YOU? - cvut.cz · PowerPoint-presentatie Author: Bard de Vries Created Date: 6/4/2014 4:56:22 PM](https://reader035.vdocument.in/reader035/viewer/2022071605/6141490a6d7bf66e09136db7/html5/thumbnails/15.jpg)

And then…..
Go to www.datex2.eu
Register
Look for a fitting profile
Or create one yourself after downloading all stuff. But.... This is not a rooky
exercise.
Create extensions if needed
Use the DATEX II website and available fora to ask the specialists

DATEX II and other standards
Tight relation with ISO working group especially on exchange between
traffic centres
The possibility to ISO standardise the content part is perceived to be rather limited
Relation to TPEG
TPEG is standard for a specific set of end-user services. It can be fed by some parts
of DATEX II (but surely not all)
Close liaison is established to ensure interoperability for safety related information
Relation to ETSI
Development of cooperative standards esp. V2x. For x=I tight cooperation is
required to ensure interoperability
