Research Report 263 The effect of cross-sectional geometry on heavy vehicle performance and safety
Published: 2005The primary objective of this study, done between July 2003 and June 2004, was to determine relationships between road cross-sectional geometry and heavy vehicle performance and then to use these relationships to estimate the effect of road geometry on heavy vehicle crash risk.
Keywords: crash risk, vehicle performance, cross-sectional geometry, safety.
Research Report 271 School journey safety: a comparative study of engineering devices
Published: 2006The aim of this research, carried out in 2004, is to improve safety for children on their home to school journey. This is to be achieved by comparing the effectiveness of engineering safety devices used both in New Zealand and overseas, and to provide a framework for the development of a comprehensive toolbox to assist engineering practitioners and the community in selecting appropriate...
Research Report 287 Multi-lane roundabout designs for cyclists
Published: 2006Multi-lane roundabouts are typically viewed by cyclists as one of the most hazardous
types of intersections to negotiate and police crash statistics bear this out. For the
purposes of this research, the definition of a ‘multi-lane roundabout’ is that of a
roundabout that accommodates more than one lane of traffic on the circulating
carriageway.
In 2003, scheme...
This study, carried out in 2004 at the Traffic and Road Safety Research Laboratory, University of Waikato, assessed driver reactions to 16 road hazard warning signs of various formats. A range of measures, including attentional and search conspicuity, implicit and explicit recognition, dynamic and static comprehension, and sign priming were collected for hazard warning signs for road works,...
Recent government legislation and policy promotes an increase in walking
and cycling as an alternative to the increasing demand for motor vehicle
travel. Concern exists, however, that an increase in these modes, particularly
cycling, could lead to a substantial increase in pedestrian and cyclist fatalities
and injuries.
In this research, carried out between 2002 and 2004,...
Research Report 293 Management of skid resistance under icy conditions on New Zealand roads
Published: 2006Traditionally, treatment of frost, ice and snow on New Zealand roads has involved spreading of mineral grit on the affected areas but this has disadvantages. Common salt was used as a de-icing agent until the early 1980s when public concerns about vehicle corrosion led to its use being discontinued. A major review of options for de-icing of state highways was then carried out in 1996 by...
Research Report 310 The safety benefits of brighter roadmarkings
Published: 2006Since about 1997 the brightness of roadmarkings on a number of New Zealand state highways has been increased. This study was undertaken to determine whether an increase in safety, as measured by reduced crashes, could be associated with the use of these brighter roadmarkings.
Keywords: curve, delineation, edgeline, edgemarker, ratio, reflectivity, regions, retroreflectivity,...
Research Report 312 Safety implications of flush medians in Auckland City: further analysis
Published: 2007Between July 2004 and February 2006, research was continued on the safety implications of flush medians in Auckland, New Zealand. A site-by-site benefit/cost analysis found that 38% of studied sites achieved a negative benefit/cost ratio, proving that separate analysis is required for every proposed flush median site. The width of a flush median was found to have no effect on overall...
Research Report 314 Accident benefits of sealing unsealed roads
Published: Feb 2007Research was carried out between 2005 and 2006 to determine if there were benefits or disbenefits associated with sealing unsealed roads, and if so, to determine a procedure for calculating the accident savings (or costs). Road data and seal extension site information were obtained from various district councils in New Zealand and combined with the Ministry of Transport’s accident data...
Research Report 322 The cost effectiveness of delineation improvements for safety
Published: Jul 2007The purpose of this research was to develop a cost management tool that would assist road controlling authorities and their consultants to prioritise delineation treatments that have added safety benefits compared with standard road markings. A spreadsheet-based cost management tool was developed and then applied to a range of typical road marking situations. It would appear that audio tactile...
Research Report 323 Curve speed management
Published: Jul 2007Horizontal curves have been recognised as a significant safety issue for many years, a more important factor than road width, vertical clearance or sight distance. This study investigates the issue of speed selection through curves from several different perspectives. The relationship between safety and curve speed in New Zealand was analysed using data from the Ministry of Transport’s...
Research Report 342 A literature review on driver fatigue among drivers in the general public
Published: Feb 2009The New Zealand government is seeking to reduce the number of road crashes that arise from driver fatigue in this country. To this end, Land Transport New Zealand commissioned a review of international driver fatigue literature (2000–2007) to assess measures against driver fatigue that would be effective for general public drivers. The review first notes that a number of disciplines...
