COVID-19 SERVICES UPDATE: Information on Waka Kotahi services

In collaboration with the Road Efficiency Group (REG), Waka Kotahi is releasing versions of the Asset Management Data Standard (AMDS) for review.

Road Efficiency Group

Further versions containing additional asset types and non-asset entities will be released for review to seek feedback prior to the roll out of the AMDS beginning in July 2021 and completed by 2029.

The reasons for releasing the AMDS in draft versions before final publication are to:

  • test suitability for use and gauge impact on people, systems and processes
  • stimulate discussion between transport asset data and asset management experts across the sector
  • gather feedback to iterate and improve
  • provide visibility to asset management software (AMS) vendors
  • enable early prototyping which will be undertaken by a small, representative group of road controlling authorities to test the impact of the new standard ‘in action’.

Work programme and timeline

If you would like to provide feedback, please request access below. We would especially appreciate feedback from those who work within the local government and transport sectors.

The data model

12 blue circles with the names of the concept schemes inside placed around in a circle with lines connecting them in the middle.

We have illustrated the second release of the data model for AMDS at a high-level. We invite you to play around with the model to explore the asset types being proposed, their structures and relationships.

Technical specifications

The technical specifications, asset definitions and contextual data for the following asset types is the second of four modules released for feedback over the review and feedback period:

  • Locations: A draft cross-agency Location referencing standard is the first major component. It proposes a location referencing standard to be used across sectors and infrastructure types. It proposes a spatial first concept, with linear referencing and centre-line included for pavement and surface and rail assets
  • Zones: The second significant and related area is the concept of zones. Zones will allow us to capture multiple overlays to transport assets including environment, heritage, safety, speed, multi-modal and land use areas. It will help to resolve the handling of lanes, centre-line and linear referencing
  • Devices: Release v0.2 will then add to the ‘devices’ group and will include physical traffic controlling devices like traffic islands, speed humps and road markings plus street lights.

Note: Remaining ITS assets plus structures including bridges, geo-technical and water assets will follow in Release v0.3 in early 2021. Release v0.3 will also include changes to pavement and surfacing, barriers and device supporting structures in response to feedback to v0.1.
