Routable Road Centreline A Main Roads Perspective
Steve BostonManager Asset & Network InformationAugust 2009
Asset and Network Information
Main Roads Western Australia is entrusted with providing access to one of the largest geographically spread roads networks in the world.
Our purpose is to provide safe and efficient road access that will enhance community lifestyles and ensure economic prosperity
We are road managers
Asset and Network Information
How do we manage our data ?
We manage our roads from an asset management perspective.
All road agencies worldwide manage their assets in a linear referencing manner.
Spatial is important to us, but not our main focus.
We are ‘roads’ centric, not ‘GIS’ centric with all our data management
Asset and Network InformationOur use of spatial is increasing All our road attribute data is spatial but we
don’t store it that way GIS applications are in use and are being
developed further Mobile solutions will see a greater use of
spatial data collection and GPS positioning in the field
Our external customers are demanding greater access to our data
Internally, our reliance on and preference for linear is unlikely to change.
Asset and Network Information
Integrated Road Information System (IRIS)
IRIS is a customised COTS solution IRIS manages most of our corporate
road data and information IRIS manages our Network Control
System (linear referencing) The NCS is essentially our x, y and
measure (slk) IRIS is based on a link / node model.

Asset and Network Information
What’s in IRIS All State, local roads and PSP’s ~
150,000 km’s Administrative data eg road
hierarchy, RAV routes Inventory data eg speed zones,
lanes, surface. Road Use data eg traffic volumes,
vehicle classifications, travel time, crash
Road Condition data eg roughness, video
Asset and Network Information
How do we manage the data?
Integrated system (IRIS) that’s centrally managed
Data management plans and owners for all data
Standards and representation guidelines in place
Road Information Centre – Knowledge Base
On every desktop including remote access by contractors
Asset and Network Information
Maintenance of dataNCS and administrative data State roads are updated as a result of Main Roads
initiating ‘work’ on the network Local road updates are lodged with MRWA by LG using
ROMANInventory State and some Local road data updates by data
owners as part of change process Local road updates provided by LG within ROMAN /
IRIS update processRoad Use Continuous monitoring Programmed capture programsCondition Regular network surveys
Asset and Network Information
RRC Issues Main Roads spatial centreline suits asset
management requirements at present. We currently don’t have a business case to
capture some navigation attributes. Without a business need it’s impossible to
have sustainable data maintenance in place Customer service obligations are now driving
us towards evolving a Navigation capable centreline
The challenge for the RRC group has always been in understanding the gap
Asset Management ≠ Navigation ≠ Mapping
