Intelligent Transport Systems
Design and implementation of ITS solutions including Variable Mandatory Speed Limits (VMSL) for Smart Motorway operations, SCATS-based signal optimisation, traffic-signal contract management (NZS 3917:2013), and Variable Electronic Speed Signs for speed-management programmes.
Who it's for
- NZTA Waka Kotahi
- Local councils
The problem we solve
ITS only delivers if it's specified, integrated and contract-managed properly — signals, smart-motorway controls and speed systems that talk to the network and the operator, not just to themselves. Poorly specified ITS becomes expensive infrastructure that no one can rely on.
TTAP designs and manages ITS to the operational need — VMSL, SCATS signal optimisation, variable speed signs and signal contracts — so the technology integrates with the network and does the job it was bought for.

- Detection & traffic-data systems
- ITS design & specification
What you get
- VMSL design for Smart Motorway operations

- Variable Electronic Speed Sign design for speed-management programmes
- Traffic-signal contract management to NZS 3917:2013
- ITS specification and integration advice
- Detection and traffic-data system design
How we work
- 01
Define the operational need
We start from what the network operator needs the system to do, not from a product.
- 02
Specify & design
We specify and design the ITS — VMSL, SCATS, variable speed signs — to the relevant NZ standards.
- 03
Integrate & commission
We make sure it integrates with the existing signals, control room and data systems, and commission it properly.
- 04
Manage & optimise
We manage the signal contract and optimise operation so performance is maintained over time.
Standards
- NZS 3917:2013 (traffic signals contract)
- NZTA ITS & SCATS standards
- Land Transport Rule: Setting of Speed Limits 2024
Tools
- SCATS
- VMSL / variable electronic speed-sign systems
- Detection & traffic-data platforms

Who leads this work
Frequently asked
Can you manage our traffic-signal maintenance contract?
Yes — we provide traffic-signal contract management to NZS 3917:2013, covering specification, supplier coordination and performance, so the signals stay reliable and the contract stays defensible.
Do you work on Smart Motorway and variable speed systems?
Yes. We design Variable Mandatory Speed Limits for Smart Motorway operations and Variable Electronic Speed Signs for council speed-management programmes, specified to integrate with the wider control environment.
Can you optimise our existing SCATS signals?
Yes — SCATS-based signal optimisation is part of the service, tuning existing signals to current demand rather than assuming new hardware is the answer.
