INSPIRE network – the backbone of asset information management for European road lifecycle management with linked data

(Submission #205)


From September 2016 to August 2018 a CEDR (Conference of European Directors of Roads) research project has been conducted by the consortium INTERLINK into asset information management for European roads’ lifecycle management, using linked data. This research aims to improve interoperability between the European National Road Authorities (NRAs) and their stakeholders.

INTERLINK objectives

There are four main objectives of the INTERLINK research. Firstly, to explore the procurement of road asset information by NRAs for better asset management. The research also investigates suitable data structures for asset information, and aims to develop common principles for a European Road Object Type Library (OTL). It also designed and tested a basic European Road OTL, connected to existing open standards. For road asset managers it is of crucial importance that the European Road OTL facilitates the mapping of the existing country-specific ontologies and information models. European directives like INSPIRE can be a bridge between the country-specific ontologies and information models and the European Road OTL.

Common principles

These principles describe a hybrid approach combining the strengths of currently applied open standards such as INSPIRE with linked data and semantic web technology. Bringing the available OTLs together in a harmonized framework requires a set of modelling and implementation principles. The INTERLINK project proposes a new approach towards the standardisation of information exchange and sharing and proves this concept based on real-life use cases. Applying linked data and semantic web technologies gives NRAs the opportunity to guide standardisation initiatives towards an evolutionary, modular and bottom-up approach. The European Road OTL, as a software vendor-neutral and open standardised system with a focus on data sharing, will eventually be applicable to the whole lifecycle of infrastructure assets.

A roadmap for the European Road OTL

A roadmap for development and implementation of the European Road OTL has now been established. During the lifetime of INTERLINK, a proof-of-concept of the approach was developed by using some of the selected OTLs in three test cases. In these test cases the INSPIRE network, the Linear Reference Network (LRN) is the backbone system in of the European Road OTL with IFC Alignment and InfraGML Alignment as linked files. In our presentation, we will show the results of these test cases and how the implementation of INSPIRE can support the development of improved asset information management and improved cooperation between decision-makers, asset managers and contractors, Doing it Together with industry and road authorities.
