1. CEDR-INTERLINK PROJECT
CEDR – Conference of European Directors of Roads
Objective: develop and apply way to define, link, manage infra asset info
Focus on Roads
Using W3C Linked Data approach
Allign with parallel standardisation initiatives
Share best practice between NRAs
September 2016 – Autumn 2018
Deliverable: European Road Object Type Library (OTL)
To be tested in three test cases: Nordic countries, Germany, Netherlands

WHY LINKED DATA / SEMANTIC WEB?
(Open) Data: data common denominator in life-cycle and over supply-chain;
data liberated from applications
Linked: data from multiple sources connected
Web: based on common W3C technology
Semantic: adding meaning to data to make it computer interpretable

LD / SW is a powerful (the only?) technology that can help to meet
the business needs

EUROPEAN ROAD OTL (EUROTL)
Framework of harmonised and linked existing OTLs on European level for
Road Asset Management Data
The EUROTL is a set of recommendations for National Road Authorities
Tested in three test cases: Nordic, Germany, Netherlands
After the project, road authorities can:
Gradually evolve from document- to data-driven, in a hybrid solution
Make data sets uniform using Modelling & Linking Guide
Reuse OTLs from the EUROTL and connect to national OTLs

USE OF THE EUROTL
1. Use M&LG to (re)model internal OTLs
2. Re-use OTL(s) that are part of EUROTL
3. Share national OTLs for reuse by others
4. Define best practice
5. Harmonise
6. Standardise: prescribe the use of a part of the EUROTL

4. DISCUSSION
In small groups, please, discuss the following:
If you were advising the government or a public body with a large stock of
infrastructure assets, what recommendation would you provide for
improving their asset information management?

LESSONS FROM THE NETHERLANDS
Based on experiences with Rijkswaterstaat, Dutch national road authority
AIM started in 2011, since 2014 applied in major road reconstruction project
Now for all new projects, starting with large maintenance contracts
Some achievements have been brought into international standardisation
Lessons
Synchronous developments in departments
Strive for sharing data
Use linked data power
Align with supply chain partners and other authorities
Slice your OTL up in manageable domain OTLs
16 May 201723 | The INTERLINK Approach - Using open standards for road asset information management
5. THREE TEST CASES
NRA use cases and data
Nordic (Sweden & Norway) – Trimble, Triona
Germany – AEC3, interactive instruments, planen bauen 4.0
The Netherlands – RHDHV, TNO, Semmtech
Use case-based definition of EUROTL requirements (bottom-up)
Demonstrate that business needs can be met with INTERLINK Approach
Use existing commercially-available software
Help NRAs and industry to understand implementation

Load from NRA system with condition data
Relationship through network model
Mobile plugin to ArcGIS Online
Real-time condition update
Permissions based, suitability = ‘for information’
Contractual data handover = ‘for approval’
Linking data from multiple domains to derive asset
management value
Identify assets
Book road space
Inspect, record, update system
Submit FYI and formal approval
Overlay with accident records
6. VISION FOR ASSET INFORMATION MANAGEMENT
Data should be liberated and shared
Big-mama, Mother-of-all-Models doesn‘t exist: Combine existing (open)
standards in separate modules, with network model as a core
The actual ICT landscape is hybrid and will be so for a long time
Linked Data is the glue
Develop your OTLs from the bottom up and reuse where possible

Bart Luiten, Aonghus O'Keeffe 18
ROADMAP FOR YOUR ORGANISATION
Choose strategically for data-orientation using (open) data standards
Accept multiple formats / levels of information and use linked data as glue
Select your modelling (& linking) guide, pref. harmonised with business
partners, KISS
Define your modular OTL framework , pref. harmonised with business
partners
Select, develop, implement your separate OTLs; starting small, reusing
where possible
Implement in object-based systems, visualise data
16 May 201735 | The INTERLINK Approach - Using open standards for road asset information management
SUGGESTIONS FOR JOINT EFFORTS
Just-do-it on a small scale, learning by doing
Experiment with Linked Data / Semantic Web
Share knowledge and experiences
Leadership
Shared vision on asset information management
Collaboration between public – industry – academia
National Proof of Concept project, demonstrating added value & feasibility
Share, harmonise, standardise modular OTLs
Stay in touch with European / international developments
