Project introduction

Auckland Network Optimisation is a joint programme between NZ Transport Agency Waka Kotahi and Auckland Transport to improve network efficiency and effectiveness making it safer and easier for people and goods to get around the region using our existing network.

About the Auckland Network Optimisation Programme

With Tāmaki Makaurau Auckland growing fast, an additional 700,000 to 1 million people are expected to call the city home over the next 30 years, requiring over 270,000 jobs. An effective response is necessary to manage and offset traffic congestion on the road network today, and in the years that follow. 

Auckland Network Optimisation aims to improve the performance of Auckland’s transport network, by providing more effective travel choices that focus on efficiency, resilience and value for money while improving overall safety

A major part of Tāmaki Makaurau Auckland’s future growth in travel demand will need to be addressed by utilising existing transport corridors. To achieve this, the city needs to make better use of the existing transport system to help shape a more vibrant, resilient and productive future transport network where everyone can get where they need safely and quickly. There is a focus on overall travel time savings by improving efficiency for freight, high occupancy vehicles and public transport.

  • Smarter use of the existing network

    Network optimisation looks at making relatively inexpensive and quick changes to our roads and paths to improve, efficiency and safety, support economic growth outcomes, and reduce reliance on only major infrastructure projects to improve our transport network.

    The 10-year programme consists of around 200 individual projects and activities which together as a package will improve our network’s productivity, sustainability, agility and reliability. It is made up of both physical and technological projects which will provide more travel choices with a focus on higher occupancy modes, resilience, more effective freight movement and better managed congestion for everyone on our roads.

    Examples include converting existing lanes to new bus or transit lanes keeps people and goods moving and supports reliable public transport which contributes to a more connected and productive city. Closing the gaps in deficiencies in our network will better connect people and places to thriving communities whilst providing more travel choices.

  • Technology driving better transport outcomes

    Some projects you won't see but will notice their impact when using the transport network. These include trialling new technology for improvements to intersection operations, the introduction of additional bus priority at traffic signals and new systems for the network operators to optimise the network in real-time.

    Leveraging our existing network using data, technology and insights will allow us to optimise the use of the network to help manage flows and congestion.

    Key initiatives include:

    • Bus Booster: to improve the customer experience by reducing customer wait time, AT has recently introduced technology at signalised intersections, called the Bus Booster, to give buses priority, so they can keep to schedule.
    • Smart Detection: camera technology that detects queues of vehicles, pedestrians, and cyclists at signalised intersections to adjust the traffic signals in real-time and improve intersection efficiency.
    • Dynamic Streets: use technology to change traffic lane usage for different purposes at different times of the day based on demand which goes beyond standard fixed time special vehicle lanes.

  • Programme background

    In 2020, Auckland Transport (AT) and NZ Transport Agency Waka Kotahi (NZTA)boards signed off the Auckland Network Optimisation Programme (ANO) Business Case and approved funding for a Single Stage Business Case (SSBC).

    In early 2022, both boards approved the joint business case. The joint business case recommended around 200 projects to be delivered by 2031. This package includes both physical infrastructure and technology, innovation and, behaviour change projects and activities. 

    NZTA and AT have a crucial role in supporting Aotearoa New Zealand towards its economic growth outcomes and a resilient future. The actions and decisions taken for the land transport system today, will help shape the future.

  • Programme benefits

    The ANO programme strongly aligns with the outcomes that the Government expects will be achieved and are outlined in the Government Policy Statement 2024.

    • Reduced journey times and increased travel time reliability.
    • Less congestion and increased patronage on public transport.
    • Better use of existing capacity.
    • Improved access to markets, employment and areas that contribute to economic growth.
    • More efficient supply chains for freight.
    • A more resilient network.
    • Reduction in deaths and serious injuries.
