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

Promoting the use of LOD DATEX II

The project will boost the basic access service to open traffic data through the LOD enhanced Traffic Information System (TIS), according to the ITS Directive (2010/40/EU). This will be enabled for viewing and downloading, as well as to improve 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 promote the use of LOD DATEX II as complementary to DATEX II XML, facilitating 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 due to the need for exchanging information among traffic centres of motorway operators. Soon there was the need to open this information to other service providers and DATEX I was somewhat too limited for this and used outdated technical concepts, this impulsed the development of DATEX II in the early years of this millennium.

Using a specific metadata model

The project aims to use a specific common metadata model to represent traffic information and make it accessible through National Access Points (NAPs). It intends to increase interoperability by homogenising the descriptors of data catalogues. If necessary, it will also take into account the 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. This 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 across two Member States, namely the Czech Republic and Spain. It aims at making data 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 the 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 various countries and sectors (transport, geospatial, environmental, weather, etc.). Business, researchers, national operators and administrators, as well as citizens, in general, will benefit from having dynamic traffic open data linked to other heterogeneous datasets across the 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.

What is the European Data Portal?
The European Data Portal is an online portal that gathers metadata (data about the data) published by public bodies across Europe, collecting 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

LOD-RoadTran18 aims at disseminate the project’s progress and outcomes to administrations and authorities of traffic data in Europe (especially to NAPs, European National Access Points for Traffic Data). However, we also aim to communicate to a broad audience as traffic data can be used by either end-users or service providers. For this reason we publish our progress in our news area and on social media. You can download information about the project from our website. 


The LOD-RoadTran18 project on Public Open Data has started

The project was approved in the framework of the 2018 CEF Telecom Call – Public Open Data (CEF-TC-2018-5).

The LOD-RoadTran18 project

INEA selects the proposal LOD-RoadTran18 for a grant under the CEF-Telecom Public Data call.
