Recommended Reference Profiles - RTTI

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.

Recommended Reference Profiles

The documentation on this page give a harmonised interpretation of the data categories in the Delegated Regulations A, B, C and E of the EU ITS-Directive 1040.

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 670/2022

For the Delegated regulation 670/2022 data profiles for the following datacategories will be developed:

The types of data on infrastructure:
1. road network links and their physical attributes:
  1. geometry;
  2. road width;
  3. number of lanes;
  4. gradients;
  5. junctions.
2. road classification;
3. location of tolling stations;
4. location of service areas and rest areas;
5. location of recharging points for electric vehicles and the conditions for their use;
6. location of compressed natural gas, liquefied natural gas, liquefied petroleum gas stations;
7. location of refuelling points and stations for all other fuel types;
8. location of delivery areas.
The crucial types of data on regulations and restrictions:
1. static and dynamic traffic regulations, where applicable:
  1. access conditions for tunnels;
  2. access conditions for bridges;
  3. permanent access restrictions;
  4. speed limits;
  5. freight delivery regulations;
  6. overtaking bans on heavy goods vehicles;
  7. weight/length/width/height restrictions;
  8. one-way streets;
  9. boundaries of restrictions, prohibitions or obligations with zonal validity, current access status and conditions for circulation in regulated traffic zones;
  10. direction of travel on reversible lanes.
2. traffic circulation plans.
Other types of data on regulations and restrictions:
1. the location and identification of traffic signs reflecting traffic regulations and identifying dangers:
  1. access conditions for tunnels;
  2. access conditions for bridges;
  3. permanent access restrictions;
  4. other traffic signs reflecting traffic regulations.
2. static and dynamic traffic regulations, where applicable, other than traffic regulations referred to in point (2);
3. identification of tolled roads, applicable fixed user charges and available payment methods (including retail channels and fulfilment methods);
4. variable road user charges and available payment methods, including retail channels and fulfilment methods.
The crucial types of data on the state of the network:
1. road closures;
2. lane closures;
3. roadworks;
4. temporary traffic management measures.
Other types of data on the state of the network:
1. bridge closures;
2. accidents and incidents;
3. poor road conditions;
4. weather conditions affecting road surface and visibility.
The types of data on the real-time use of the network:
1. traffic volume;
2. traffic speed;
3. location and length of traffic queues;
4. travel times;
5. waiting time at border crossings;
6. availability of delivery areas;
7. availability of recharging points and stations for electric vehicles;
8. availability of refuelling points and stations for alternative fuel types;
9. price of ad hoc recharging/refuelling.
