Research Report 542 Ongoing domestic freight volume information study

Published: Mar 2014
  • Reference: 542
  • ISBN: 978-0-478-41903-0
  • Author: R Paling, Richard Paling Consulting, Auckland | M King, Murray King and Francis Small Consultancy, Wellington | J Ballantyne and C McBride, Traffic Design Group, Lower Hutt | A Gray, Statistics Research Associates, Wellington

The availability of comprehensive and reliable information on the movement of freight is increasingly seen as an important element in the effective planning for the sector, both by those providing infrastructure and those providing services. However, the main source of data on freight movements, the Ministry of Transport's National Freight Demand Study, was based on data that is now...

Research Report 546 Measuring the resilience of transport infrastructure

Published: Feb 2014
  • Reference: 546
  • ISBN: 78-0-478-41915-3
  • Author: JF Hughes and K Healy - AECOM New Zealand Ltd

Internationally there is a growing call to improve the resilience of our critical infrastructure. This is in response to a realisation that the services we take for granted may be robust in the face of predictable hazards/failures, but are in fact extremely fragile in the face of unanticipated shocks.

In the context of transport infrastructure, operators strive to ensure that transport...

Research Report 543 Pavement design for specialist surfacings

Published: Jan 2014
  • Reference: 543
  • ISBN: 978-0-478-41905-4
  • Author: G Arnold, A Stubbs and J Vercoe - Road Science

Leutner shear tests to measure bond strength and flexural beam tests to measure flexibility were conducted on specialist surfacing resins used in New Zealand for coloured and high-friction surfacings. The flexural beam tests found the specialist surfacing resins, except for one, to be very flexible at 5 and 20 degree test temperatures. This flexibility showed that the specialist surfacing resins...

The goal of the research was to evaluate the effects of alcohol on the performance of New Zealand drivers across 0.05% and 0.08% blood alcohol concentration (BAC) levels. An experimental test was conducted with 61 participants assigned to one of two alcohol dose conditions or a placebo control group. Comparison of alcohol doses showed that a BAC of 0.08% produced a level of impairment...

  • Reference: 535
  • ISBN: 978-0-478-40784-6
  • Author: D Barnston, R Brill, A Harding, NJ Jamieson, M Ladd, N Stillwell - Opus International Consultants

A potential gap between available location technology and its use on the ground was identified in the New Zealand land transport sector. This research sought to bridge that gap and support the NZ Transport Agency's ('Transport Agency') goal to increase the use of appropriate location technology by its key providers. Consultation with these was undertaken to understand the...
