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

INDUSTRY’S NEEDS AND NEXT STEPS

Needs statements, e.g.

Publish information requirements

Gather information through life cycle using best available format

Open standards

Access info through GIS or BIM

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 16 May 201711 | The INTERLINK Approach - Using open standards for road asset information management

FROM ONE STAR TO FIVE STAR LINKED OPEN DATA: THE HYBRID APPROACH



16 May 2017


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


National

European

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?



16 May 2017


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


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



16 May 2017


NORDIC CASE – ROAD LIGHTING IN JAREN




Based on NVDB and NRA

Asset ID, functional and

technical requirements

Equipment ID, fulfilment of

requirements

Automated validation of data

against AIR

Mimic future RDF-based

NVDB asset data

Lighting object type

Design stage instance data

Construction stage instance data

Handover process

NVDB instance data


16 May 2017




Gather life-cycle data with asset object, easing future access

Record design and construction history (e.g. approval)

Structured and unstructured => hybrid, gradual transition

Extended existing BIM software to query triple store and read Linked Data

GERMAN CASE – BRIDGE IN HAMBURG

Tool from buildingSmart

German road classification system used for asset

information management

Export to IFC (67 MB)

Filter to IFC without 3D (64 KB)

Convert to IFC RDF

Link with ASB-ING

Widerlager (ASB-Ing)



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)

DUTCH CASE – REPAIR AND INSPECTION IN SOUTH HOLLAND


Maintenance contractor

Barrier inspection

Info. delivery manual

3 month delay from inspection to

NRA system update

Affects validity of KPIs

Duplicate asset information




16 May 2017




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



16 May 2017


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


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
