Research Report 383 Measurement of the reflection properties of road surfaces to improve the safety and sustainability of road lighting

Published: | Category: Research & reports , Research programme | Audience: General

This study reports on a New Zealand-wide evaluation of road surfaces for reflection properties relevant to road lighting design. The sections of road to be surveyed were chosen from the national Road Assessment and Maintenance Management database (RAMM) on the basis of location, age and surfacing material. The measurement device was the portable reflectometer known as ‘Memphis’. Road lighting for safety in New Zealand is currently based on the Australian and New Zealand standards AS/NZS 1158.1.1:2005 and AS/NZS 1158.2:2005, and use modified CIE tables of pavement reflectance based on New Zealand measurements made in 1982.

Research Report 342 A literature review on driver fatigue among drivers in the general public

Published: | Category: Research & reports , Research programme | Audience: General

The 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 study driver fatigue, each using its own definitions and so emphasising different measures. This constrains the development of measures and longer-term programmes for the general public. The review thus notes the need for evidence-based theory specific to general-public driver fatigue. This would enable clearer understanding and facilitate the design, management and evaluation of programmes.

Research Report 509 The next generation of rural road crash prediction models: final report

Published: | Category: Research & reports , Research programme | Audience: General

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 considerable potential for proactive safety improvements. This report presents the third and final stage of a study that aims to develop crash prediction models for two-lane rural roads using data from almost 7000km of the rural state highway network. The report builds upon the findings of stage 1 (scoping study) and stage 2 (pilot study) to determine the most important parameters affecting safety on rural roads in New Zealand. The models have quantified the mathematical relationship between crashes and traffic volumes, road geometry, cross-section, road...

Research Report 344 Personal security in public transport travel in NZ: problems issues and solutions

Published: | Category: Research & reports , Research programme | Audience: General

This research project explores concerns about personal security by users of public transport. The findings from an international literature review are used, and the concerns of public transport users in three New Zealand cities (Auckland, Wellington and Christchurch) that have significant public transport patronage streams are explored. Personal security concerns were found to discourage existing patrons from using public transport, and more so after dark. A number of security measures preferred by patrons are outlined. However, the project also found that only a small proportion of patrons actually noticed the presence of security measures that had been installed.

Research Report 386 Roundabout crash prediction models

Published: | Category: Research & reports , Research programme | Audience: General

The management of speed is considered an important safety issue at roundabouts. The approach speed and negotiating speed through roundabouts depends on the geometric design of the roundabout and sight distance. In New Zealand and in Australia, the design standards recommend long approach sight distances and provision of relatively high design speeds. This is in contrast to European roundabouts, where visibility is normally restricted and the geometric design encourages slow approach and negotiation speeds. This work, undertaken in 2006, extends previous research by the authors developing crash prediction models at roundabouts to include sight distance, intersection layout and observed speed variables.

Research Report 085 Review of accident analysis procedures for Project evaluation manual

Published: | Category: Research & reports , Research programme | Audience: General

The Transit New Zealand Project evaluation manual (1996) outlined the procedures to be adopted when evaluating roading projects in New Zealand. In 1996, as part of the periodic updating of project evaluation methods, two aspects of the accident analysis procedures were reviewed. The issues addressed were the increased severity of accidents that occur at higher speeds; and the prediction of reduction in accident rates that result from improving curves.

Research report 428 Trialling pedestrian countdown timers at traffic signals

Published: | Category: Research & reports , Research programme | Audience: General

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 trial at the Queen Street/Victoria Street intersection in Auckland CBD and showed very different results. The Auckland city trial indicated that, if placed in suitable locations, pedestrian countdown signals were associated with pedestrian behaviour change that enhanced safety. This study in Lower Hutt demonstrated that the observed pedestrian safety decreased as the percentage of both late starters and late finishers increased, although this was likely to be due to the nature of the intersection with one particularly long diagonal crossing coupled with the allocated phase times.

Research Report 047 Accident trends in New Zealand

Published: | Category: Research & reports , Research programme | Audience: General

Recommendations are presented for adjustments to the procedures used by Transit New Zealand for determining accident savings from road improvements for project evaluation. The adjustments allow for general trends in New Zealand road accidents arising from those road safety programmes other than road improvements.

Research Report 510 Evaluation of the C-roundabout an improved multi-lane roundabout design for cyclists

Published: | Category: Research & reports , Research programme | Audience: General

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 Drive/Sturges Road intersection in Auckland and was evaluated between 2008 and 2011 in terms of its safety, capacity, and the opinions of cyclists, pedestrians and car drivers. The C-roundabout successfully reduced vehicle speeds to 30km/h, which is close to the speed of cyclists. This made the roundabout safer for cyclists, as well as for other road users. The installation of the C-roundabout at this uncongested site had little impact on capacity. It drew positive feedback from cyclists and pedestrians, but about half of the car drivers were not in favour of it.

Research Report 180 Cycle audit and cycle review: a scoping study

Published: | Category: Research & reports , Research programme | Audience: General

This study was an investigation to see whether the process of cycle audit and cycle review developed by the Institution of Highways and Transportation in the United Kingdom should be introduced in New Zealand. The researchers interviewed traffic engineers and planners, road safety coordinators and cycle officers in nine local authorities, as well as cycle advocates, regional authority staff and Transit New Zealand staff.
