THE INTERLINK APPROACH - USING
OPEN STANDARDS FOR ROAD ASSET
INFORMATION MANAGEMENT
bSI Tokyo 2018 | Bart Luiten - [email protected]
1. CEDR-INTERLINK PROJECT
Client = 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
Align with parallel standardisation initiatives, bSI, OGC, national
Share best practice between NRAs
September 2016 – Autumn 2018
Deliverable: European Road Object Type Library (EUROTL)
Tested in three test cases: Nordic countries, Germany, Netherlands

2. UNDERSTANDING THE
INDUSTRY’S NEEDS
18 October 20183 | The INTERLINK Approach - Using open standards for road asset information management
Preliminary Needs Statements
Literature review
Interviews
Surveys
Analysis
Final Needs Statements
INDUSTRY’S NEEDS AND NEXT
STEPS
Needs statements, e.g.
Publish information requirements
Gather information through life cycle using best available structure & format
Use open standards for GIS, BIM, systems engineering
Work towards a digital twin
Information management functionality based on use cases
Recommendations to NRAs
Linked data & standardisation – active contribution, sharing, open
Capital works and maintenance contracts – validate, certify, scale
Project and asset managers – start small – top five
Learn from each other – UK, DE, NL, NO, SE, FI
Recommendations to Supply chain
Software companies – extension to LD/SW
Engage with INTERLINK consortium 18 October 20184 | The INTERLINK Approach - Using open standards for road asset information management
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, powerful, complete, distributed W3C technology
Semantic: adding meaning to data to make it computer interpretable;
automatic data verification and reasoning
18 October 20185 | The INTERLINK Approach - Using open standards for road asset information management
LD / SW is a powerful (the only?) technology that can help to meet
the business needs
CEDR-INTERLINK video on the European Road OTL
https://youtu.be/gczSTEyif5Y18 October 20186 | The INTERLINK Approach - Using open standards for road asset information management
EUROPEAN ROAD OTL (EUROTL)
A network of harmonised and linked existing standards and OTLs 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 OTLs and their datasets uniform using Modelling & Linking Guide
Reuse standards and OTLs from the EUROTL and connect to national
OTLs

LINKING EUROPEAN ROAD OTL
TO OTHER STANDARDS

Links to existing
international
standards and OTLs
Links to existing
national standards
and OTLs
HOW NRAS CAN USE THE
EUROTL
1. Do your own test case using INTELRINK results
2. Use M&LG to (re)model internal OTLs
3. Re-use OTL(s) that are part of EUROTL
4. Share national OTLs for reuse by others
5. Define best practice
6. Harmonise
7. Standardise: prescribe the use of a part of the EUROTL

5. THREE TEST CASES: PROVE
ADDED VALUE AND FEASIBILITY
NRA test cases and data
Nordic (Sweden & Norway) – Trimble, Triona
Germany – AEC3, interactive instruments, planen bauen 4.0
The Netherlands – RHDHV, TNO, Semmtech
Test 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

Query objects by ASB-ING class in triple store
Visualise in IFC viewer (Desite)
6. VISION FOR ASSET
INFORMATION MANAGEMENT:
KEEP IT SIMPLE AND STANDARD
Data should be liberated and shared
Big-mama, Mother-of-all-Models doesn‘t exist: Combine existing (open)
standards in separate modules, with road network model as a core
The actual ICT landscape is hybrid and will be so for a long time
Linked Data technology is the glue
Develop your OTLs from the bottom up and reuse where possible
Link to existing standards and OTLs as much as possible
18 October 201815 | The INTERLINK Approach - Using open standards for road asset information management
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 network of OTLs, pref. harmonised with business partners
Select, develop, implement your separate OTLs; starting small, reuse where
possible
18 October 201816 | The INTERLINK Approach - Using open standards for road asset information management
CURRENT STATE OF THE
PROJECT
Project nearly finished: final report publicly available in November
Modelling & Linking Guide
EUROTL core, its ontologies, fully documented
Linked standards:
INSPIRE - Road Network, incl. GeoSPARQL and GML
ifcOWL, ISO linear referencing
AM4INFRA taxonomy
SOSI, CoClass, ASB-ing, OKSTRA, COINS
National projects in Norway, Netherlands, Ireland, Sweden
CEN TC442-WG4-TG3: standardise M&LG
How about building SMART?
