Publications & presentations

We carry out transport research, think-pieces and policy guidance for national agencies, local councils, and other clients, and regularly publish and present to the industry (including many award-winning papers). Below are links to our latest published work:

  • Writing submissions: how to be effective?

    This presentation was given to the 2005 Community Road Safety Symposium. It draws the following conclusions:

    • Maintain a submission template
    • Agree on a process for dealing with diverging views
    • Submission process to suit size of organisation
    • Time management is critical
    • Earlier involvement equals increased effectiveness
  • Cycle paths at signalised cross intersections

    This remit was given to the Signals NZ User Group (SNUG) at the 2005 annual meeting in Christchurch. It draws the following conclusions:

    The current practice of not providing cycle signals is questionable.

    Cycle signals reduce LOS for both motorists and cyclists.

    Designers need to ascertain on a case-by-case basis that pathways are the right concept.

  • ARTA cycle route network analysis tool

    This conference remit describes an innovative approach developed to analyse cycle route network concepts. The remit is based on a study undertaken for the Auckland Regional Transport Authority (ARTA).

    The remit covers how to use demographic data (population, education and employment) in a GIS environment to identify which network of potential cycle routes will be most effective in increasing the number of cyclists in Auckland.

  • Making a congested offset signalised T-intersection work

    The given problem is a signalised staggered T intersection that is congested. The queue space between adjacent T intersections is filling up. There are also significant queues on the side streets. The recommendations are that modelling software should be used that is appropriate for the task, and the engineer needs to be aware of the limitations of the different software packages.

  • Paramics modelling of congested offset T-intersection

    The given problem is a signalised staggered T intersection that is congested. The queue space between adjacent T intersections is filling up. There are also significant queues on the side streets.

    The recommendations are that modelling software should be used that is appropriate for the task, and the engineer needs to be aware of the limitations of the different software packages.

  • Stops and Goes of Traffic Signals: a traffic signal auditor's perspective

    Land Transport NZ (formerly Transfund NZ) commissioned Axel Wilke to prepare this booklet. The purpose was to contribute to the objectives of the New Zealand Transport Strategy by improving the efficiency and safety of the network.

  • Building our way out of congestion

    Government policy explicitly states that we will not try to build our way out of congestion. Yet Government transportation spending is at record levels, having more than doubled in the past five years and expected to continue growing significantly. The predominant share of this is for roading, much of it for new roads, and this allocation is not planned to reduce over the next decade.

  • Planning for certainty through sustainable transportation

    This paper, from the 2005 Transit NZ Roading Symposium, looks at available data to understand congestion trends, travel time variability and fuel price and supply and looks at ways to provide certainty for transportation. The paper argues that more emphasis should be put on travel demand management and support for walking, cycling and public transport. In turn, these measures (and sustainable transportation in general) have the potential to make car travel times more predictable, thus enhancing the opportunities for “planning for certainty”.

  • Accommodating cyclists at signalised intersections

    This paper, from the 2005 NZ Cycling Conference, explores how cyclists can be accommodated at signalised intersections using specific cycle facilities and creating a more cycle-friendly environment by speed control.

  • Planning and design for cycling: developing best practice in New Zealand

    A "Cycle Network and Route Planning Guide" has been produced to provide a best practice framework for local cycle planning strategies. Similarly, a "Cycle Design Supplement" (based on the Australian "Guide to Traffic Engineering Practice, Part 14: Bicycles" but with a number of significant differences) now provides consistent guidelines for the design of cycle facilities in New Zealand.
