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

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


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

the business needs

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

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

HAMBURG


Improve ease of information handover to existing databases

Link inspection records to bridge objects (e.g. condition rating)

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


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


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?
