The DATEX II standard supports the entire domain of road traffic and road travel data provision. As a result the DATEX II content standard offers the ablitity of a coherent dataprovision for a wide variety of services in relation to traffic and travel information and management, both on a network and individual basis. To support the different types of services using the DATEX II standard, the concept of Recommended Profiles is available. A profile is a subset of the entire standard, only containing the relevant data-elements required for a specific use case.
To ensure interoperability of information services profiles need to be implemented. Systems implementing the same DATEX II profile are interoperable by definition. To support the EU Delegated Regulations on ITS and the by EU-EIP maintained deployment guides , DATEX II developped and publishes reference profiles. The requirements for these profiles either come from the harmonisation and liaison processes run in the DATEX II organisation, the EU-EIP activity 4.5 or liaison with external stakeholder communities such as TISA and C-Roads.
The EU Delegated Regulations are supported by Recommende Reference Profiles (RRP’s). These RRP’s contain the minimum set of data-elements required to provide the information meant by the specific datacategory in the specific delegated regulation. With the DATEX II webtool it is possible to combine the RRP’s to a set of RRP’s covering the available information. Apart from that, it is possible to extent the RRP with information elements that are available in the specific source.
It is of utmost importance, regarding the EC goal to provide harmonised data exchange, that the content (data categories) of the Data exchange initiated by the different regulations are modelled identical by the different operators. The supporting documentation set out very clearly which data elements are correspding to the data categories and how they are to be recognised in the profile.
With the on-going maintenance of DATEX II, DATEX II takes care that profiles and their documentation are available when new versions of the relevant parts are published.
For the Delegated regulation 1926/2017 MMTIS data profiles for the following datacategories will be developed:
Disruptions (all modes)
Real-time status information — delays, cancellations, guaranteed connections monitoring (all modes)
For road traffic, these are covered by the profiles that are supporting the datacategories defined in Delegated Regulation 962.
Current road link travel times
Cycling network closures/diversions (under consideration)
Availability of:
publicly accessible charging stations for electric vehicles and refuelling points for CNG/LNG, hydrogen, petrol and diesel powered vehicles
Car parking spaces available (on and off-street), parking tariffs, road toll tariffs
