Intelligent transport systems (ITS) apply technology solutions to deliver operational and transport management outcomes, as well as contributing to safer roads.
Waka Kotahi NZ Transport Agency owns and operates a significant number of ITS. The ITS equipment supports traffic operations and incident management. They range from traffic signals and variable message signs, through to the supporting ITS communication network infrastructure to transport operations centres (TOC).
Each ITS asset requires a set of unique and unambiguous requirements for successful implementation and operation of the asset. This is delivered through published standards and specification documents.

The standards and specifications provide assurance for delivery of solutions and the equipment and systems required to build and configure them. This breaks out into three key areas:
- Design assurance (standards)
Design assurance is delivered through a series of design standards. The standards ensure road network level operational outcomes and design for safety, security and maintainability are accounted for in solutions being delivered to Waka Kotahi. Design standards address risks typically generated at the front-end of roading or infrastructure projects. Their objective is to ensure solutions address the correct operational need and solutions are fit for purpose.
- Delivery assurance (specifications)
Delivery assurance is managed through a series of delivery specifications which support procurement and systems integration. The key risks that specifications address are ensuring the correct equipment is being procured, that it will integrate with operational systems and will deliver the correct functionality and performance requirements.
- Core requirements (standards and specifications)
Core standards outline common conditions and obligations and are applicable across all Transport Agency ITS design standards. Core specifications define common requirements and are applicable across all Transport Agency ITS delivery specifications. Their purpose is to provide clarity for each core subject area by managing duplication of common requirements within the design standards and delivery specifications.
