New Zealand has adopted the raised-profile type of audio tactile profiled (ATP) roadmarkings. This research was undertaken in 2011/2012 to help address gaps in available international literature on the stability of motorcycles when travelling on or across ATP roadmarkings.

The research investigated the stability of motorcycles when contacting ATP roadmarkings, through evidence of...

Detailed observations of air quality and local meteorology were conducted on either side of a stretch of the Auckland southern motorway, and in the surrounding residential neighbourhood. The data revealed emissions from motorway traffic contributed, on average, to a 10% elevation in concentrations of particulate matter at a roadside site relative to a setback site (150m away or more) and to a...

This report summarises research carried out in 2011–12 to quantify the effects of roadside barriers and clear zones on mitigation of run-off-road crash numbers and crash severity for New Zealand road and roadside characteristics through statistical and computer simulation modelling. The purpose of the research was to provide practitioners with information that would allow them to make...

The majority of fatal and serious crashes in New Zealand occur on rural two-lane roads. Data on historic crash patterns is not always sufficient to enable a suitable diagnosis of the safety deficiencies of various sections of this rural road network. It also cannot readily identify safety issues on low-volume roads and shorter sections of highway, where the relative scarcity of crashes may mask...

The C-roundabout (cyclist roundabout) is a new multi-lane roundabout design (developed as part of a 2006 Land Transport NZ research project Improved multi-lane roundabout designs for cyclists) that aims to improve the safety of cyclists at multi-lane roundabouts and make multi-lane roundabouts more cyclist-friendly.

A C-roundabout was installed at the Palomino Dr/Sturges Rd...

The Safe System approach to road safety implies the goal of removing fatal and serious injury crashes from our road network.

This review addresses:

• alternative ways of classifying roads in relation to speed, across the road network, compatible with the Safe System approach
• how speed relates to crashes, fuel consumption and emissions

This report presents the results of a first attempt to combine detailed road geometry, road surface condition, carriageway characteristics and crash data information to develop a statistical crash prediction model for application to rural New Zealand state highways. Such a study was made possible because high-speed surveys generating simultaneously measured road condition and road geometry data...

In most cities and towns, the majority of crash black-spots occur at major intersections. Given this, crash reduction studies often focus on the major signalised intersections. However, there is limited information that links the phasing configuration, degree of saturation and overall cycle time to crashes. While a number of analysis tools are available for assessing the efficiency of...

This research, undertaken 2008-2010, investigated the comparative safety of multi-lane roundabouts versus signalised intersections, pedestrian facilities, vertical deflection devices and visibility to the right. Guidance for practical application of the relevant measures to enhance roundabout safety has been developed and is included in this document. The Dutch turbo-roundabout was reviewed...

A key problem for local authorities is the lack of robust techniques for evaluating crash risk at high-volume, urban, priority-controlled intersections. Some crash prediction modelling tools are available, but they do not accurately predict crash rates at the higher-volume priority-controlled intersections, where at times, there are limited gaps in main road traffic flows, which often gives...

This report presents an updated statistical analysis of data relating to crash rates on New Zealand roads. The research was carried out during 2007-2009 and it precedes the changes in 2010 to the New Zealand T10 specification. The refinements presented are associated with accounting for differences between the local and the general (ie design) speed environment, crash severity and interactions...

The research identified how the physical noise and vibration generated by traversing ATP roadmarkings was influenced by the properties of the roadmarkings, such as their height, width and pitch, as well as by other factors, such as vehicle speed. The research established the relationship of human response to the noise and vibration generated. The physical effects of traversing ATP roadmarkings...

Road safety is an issue that impacts on all levels of government and population. Since a high of 843 fatalities in 1973 the overall crash rate has been declining and 384 fatalities were recorded on New Zealand roads in 2009. Although this represents a significant reduction in casualties, there is still a need to reduce the current rate of about one fatality per day.

Lessening the...

In this research project, the innovative 'hands-on' method, first developed by Walton and Thomas in 2005, was tested in its ability to evaluate the effects of improved road delineation on driver behaviour. The method uses hand positions on the steering wheel as an indicator of drivers' perceived risk, with drivers being more likely to place both their hands on the top half of the...

Research carried out in 2008-2010 examined the quantum and causes of non-motor vehicle injuries to pedestrians through a structured interview survey. Pedestrians sustaining injuries in locations away from the road network (eg in parks) were excluded, as the emphasis was on the role of road and footpath features. The highest proportion of trips and falls (34%) was sustained while stepping over a...

The overall research objective was to evaluate changes in pedestrian safety and traffic efficiency from installing pedestrian countdown timers. The study analysed pedestrian behaviour and safety before and after the installation of a trial countdown timer at the intersection of Queens Street, Bunny Street and Margaret Street in Lower Hutt in July 2007. The results were compared with the 2006/07...

The purpose of this research, carried out between 2008 and 2010, was to investigate the evidence for prioritising school travel initiatives, and to develop an evidence-based toolkit for the design of school travel systems, to supplement existing school travel initiatives.

There are tangible economic, safety, health and environmental reasons for giving greater priority to school...

Transverse road markings as a speed mitigation device may be a cost-effective method of reducing fatal and serious injury crashes as a consequence of speeding on a high-speed hazard approach. As no established marking layouts have been formally applied in New Zealand, investigations into the use and application of transverse road markings have been conducted over 2008 2010. The culmination of...

In the 21 years from 1987 to 2007 inclusive, 22 children were killed, 45 seriously injured and 91 received minor injuries when crossing the road to or from a school bus. In addition, six children were killed while passengers on a school bus. As a result, there is widespread concern about school bus safety. This research project aimed to identify and advance those measures seen as having the most...
