3 The objective of the Agency is to undertake its functions in a way that contributes to an affordable, integrated, safe, responsive and sustainable land transport system. Each year, the NZ transport Agency funds innovative and relevant research that contributes to this objective. The views expressed in research reports are the outcomes of the independent research, and should not be regarded as being the opinion or responsibility of the NZ transport Agency. The material contained in the reports should not be construed in any way as policy adopted by the NZ transport Agency or indeed any agency of the NZ Government.

While research reports are believed to be correct at the time of their preparation, the NZ transport Agency and agents involved in their preparation and publication do not accept any liability for use of the research. People using the research, whether directly or indirectly, should apply and rely on their own skill and judgement. They should not rely on the contents of the research reports in isolation from other sources of advice and information. If necessary, they should seek appropriate legal or other expert advice.

This was in response to the findings of a 2005 Ministry of transport (MoT) study , which had been commissioned to assist the government in making decisions on the relative competitive position of road and rail transport for Freight transport .

9 The MoT study revealed there was little New Zealand research available regarding actual resource usage particularly regarding the relative efficiency of the modes in the use of fuel and damage to goods during transit. This paucity of information on relative resource usage was hampering the robust economic assessment of transport -related capital works projects that could provide alternatives to roading. Methodology Monitoring/tracking system A stand-alone data logger that could covertly track the movement of an empty 20 ft container was designed and constructed for this research.

10 This logger measured the number, frequency, magnitude and time of any sudden movements and impacts a container experienced along its journey. The logger was built from off-the-shelf modules and consisted of a battery-powered device using a global positioning system receiver and 3-axis accelerometers to monitor movements and impacts. The data acquired from the global positioning system and accelerometer modules was stored in a 256-megabyte storage device. Routes Five return shipments of the 20ft instrumented container were undertaken in 2006. These five shipments encompassed the transport modes of coastal shipping , rail and road, and were from/to Seaview in Lower Hutt to/from either Christchurch or Tauranga.
