The project main objective is to support for the re-use of information made discoverable/available through the European Data Portal. In order to achieve this general objective, the following specific objectives have been set:

Promoting the use of LOD DATEX II

The project will enhance the basic service of access to open traffic data through LOD enhanced Traffic Information System (TIS), according to the ITS Directive (2010/40/EU), not only for viewing or downloading but improving the extraction of meaning from the data and allowing other types of services, which can be only achieved with the use of LOD.

The project aims to promete the use LOD DATEX II as complementary to DATEX II XML, because it will facilitate the accessibility and comprehensibility of European traffic data and services. This will entail the construction of translation (DATEX II to LOD DATEX II) and validation tools, and the development of an ontological model (DATEX II Ontology) as support.

But, what is Datex II?

DATEX II is the electronic language used in Europe for the exchange of traffic information and traffic data. The development of DATEX II was initiated in the early 90s because of the need to exchange information between traffic centers of motorway operators. Soon there was the need to open this information to service providers. DATEX I was somewhat too limited for this and used outdated technical concepts. Which is why DATEX II was developed in the early years of this millennium.

Using an specific metadata model

The project aims to use a specific common metadata model to represent this type of information accessible through National Access Points (NAPs) to increase interoperability by homogenizing the descriptors of data catalogues. If necessary, implementation of a new model and validation tools.

Developing a LOD enhanced TIS

The project aims to develop a LOD enhanced TIS with semantic capabilities, which includes the use of a LOD DATEX II and a common metadata model which would allow the incorporation of new publishers, datasets, data description and discovery services.


This project aims to support the re-use of dynamic Road Traffic Data in and across two Member States, namely Czech Republic and Spain, made findable, accessible, interoperable, and reusable through the European Data Portal, and crossed with other sector data by using Linked Open Data (LOD). The usefulness of LOD datasets about traffic information does not only lies in the inclusion of traffic open data, but in the incorporation of links to other relevant thematic datasets on the Web, which will allow federated queries from different data platforms belonging to different countries and sectors (transport, geoespacial, environmental, weather, etc.). Business, researchers, national operators and administrators, and citizens in general will benefit from having dynamic traffic open data linked to other heterogeneous datasets across different Member States.

About the CEF Programmes:
The Connecting Europe Facility (CEF) is a European key funding instrument to promote growth, jobs and competitiveness through targeted infrastructure investment at European level. It supports the development of high performing, sustainable and efficiently interconnected trans-European networks in the fields of transport, energy and digital services. CEF investments fill the missing links in Europe’s energy, transport and digital backbone.

Grant Agreement number: INEA/CEF/ICT/A2018/1803421
Action No: 2018-EU-IA-0088
Start date: 01/09/2019
Duration: 37 months
Grant: EUR 760,931
The coordination of the project will be done by IRTIC (Universitat de València)

What is the European Data Portal?
The European Data Portal is an online portal that collects metadata (data about the data) published by public bodies across Europe, collating it into a searchable tool accessible by anyone. Whether it’s a transport tech start-up trying to make commuting more efficient, or a journalist investigating government spending, they can access that data via the European Data Portal.

Main Activities

Project Coordination

This activity includes the entire planification of the Project, it will also give support to the partners and will guarantee that all the control mechanisms are being applied according to the Quality Assurance Procedures. The coordination activity will be carried out out mainly by IRTIC (Universitat de València), with the administrative and financial support of LMT and RBS.

Technical and legal requirements and support to the implementation

Analysis of legal and technical background for making Linked Open Traffic Data Actionable, to find out the impact of the implementation of the European legislation on the framework for the deployment of Intelligent Transport Systems in the field of road transport and for interfaces with other modes of transport, and its Delegated acts.

Analysis of the models for road traffic and travel information in Europe, mainly focused, but not exclusively, on the European standard DATEX II, used in many of the priority areas and services mentioned in the European ITS directive (2010/40/EU).

Actions based on PSI and ITS Directives as discovery, distribution, harvesting processes will be analysed together with linked data concepts and metadata description of services. Results of this analysis in the form of a report will be used in both the design and implementation phases of the project.

Project Implementation

Linked Open Traffic Data concept development, based on the revision of the information obtained in previous activities to design and implement necessary models (ontologies + vocabularies) for use in linked open traffic data context, considering service-related metadata.

 Technical systems proposal through the design and later implementation of a friendly interface, which allows to all data to be queried through a uniform interface.

Implementation and deployment of a LOD enhanced TIS and Testing, making Traffic data LOD actionable and available in Open Data Portals.

Project Dissemination

The main objective of this dissemination activity is twofold. First, we aim to disseminate the project’s progress and outcomes to a broad audience in order to have the highest impact, considering that traffic data can be used by all kinds of private and public stakeholders who can be either end-users or service providers. Second, we also aim to disseminate both the project’s progress and outcomes to public administrations and authorities of traffic data around Europe, especially to other European NAPs (National Access Points for Traffic Data).
