Research Report 348 The development of gravel deterioration models for adoption in a New Zealand gravel road management system

Published: | Category: Environmental impacts of land transport , Research programme , Research & reports | Audience: General

This report provides the outcomes from research based on the Land Transport New Zealand gravel road monitoring programme that commenced during 2002 and included the cooperation of 51 local authorities. These sections were monitored on a sixmonthly basis and all relevant data such as maintenance, rainfall where available and evaporation were incorporated into a national database. This research project included the provision of practical guidelines for the construction and maintenance of gravel roads. In addition, the gravel road data were analysed and outcomes are presented. The resulting models are effective indications of gravel loss on a network scale but further research would be required for more detailed models. This can be achieved by collecting more information on the impact of routine maintenance such as blading.

Research report 405 Public lighting for safe and attractive pedestrian areas

Published: | Category: Safety, security and public health , Research programme , Research & reports | Audience: General

The Australian/New Zealand standard Lighting for roads and public spaces, part 3.1: pedestrian area (category P) lighting - performance and design requirements (AS/NZS 1158.3.1:2005) sets out specifications for pedestrian lighting. The standard defines adequate and acceptable pedestrian lighting practices to make walking safe. This research project complements and extends the standard by investigating pedestrian lighting practices to make walking not only safe, but also more attractive. The project highlights issues and perspectives from which to view the effectiveness of the pedestrian lighting. This research is partly based on the observation that most lighting in the public arena has traditionally been driven by the needs of motorists, but pedestrians' needs are different. It studies those differences and guides on lighting techniques that can appropriately and specifically cater for pedestrians. The findings are based on a review of literature incorporated with information from the lighting industry.

Research Report 463 Development of tensile fatigue criteria for bound materials

Published: | Category: Activity management , CAPTIF , Research programme , Research & reports | Audience: General

Flexural beam breakage and fatigue tests were conducted in 2008–11 to determine their relationships with pavement fatigue life and tensile strain for a range of New Zealand materials for use in pavement design of stabilised aggregates. The results showed that the tensile fatigue relationships from several fatigue tests under repetitive loading could be approximated by single flexural beam breakage tests. These relationships resulted in significantly longer pavement lives than the Austroads pavement design criteria but still predicted shorter fatigue lives than what actually occurred at the Canterbury accelerated pavement testing indoor facility (CAPTIF) test track, indicating some conservatism in the approach. Further research is required to validate the tensile fatigue design procedure against actual field data. Keywords: aggregates, basecourse, CAPTIF, fatigue, beam fatigue testing, modulus, pavement design, strain, tensile strain criteria, tensile strength

Research Report 286 Investigation of implementation issues for congestion charging

Published: | Category: Integrated land use and transport systems , Research programme , Research & reports | Audience: General

The success of the recently introduced congestion-charging scheme in London has raised urban congestion charging to the fore of the transport policy debate. Also, recent legislation in New Zealand has formalised the toll road financing option, and Auckland's congestion is increasingly seen as a major issue. This project, carried out in 2003 and 2004, sought to develop best practice guidelines for developing congestion charging schemes by interviewing those involved in such systems across the world to ascertain which issues were critical to their success or failure. There was a significant degree of consensus as to what these critical success factors are:

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

Published: | Category: Safety, security and public health , Research programme , Research & reports | 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 458 A social responsibility framework for New Zealand's land transport sector

Published: | Category: Sustainable land transport , Research programme , Research & reports | Audience: General

Since the implementation of the Land Transport Management Act 2003, public sector land transport organisations in New Zealand have had the obligation to be socially and environmentally responsible, either as one of their organisational objectives (NZ Transport Agency) or in terms of the activities and combinations of activities approved for payment from the National Land Transport Fund (regional councils and road controlling authorities), While most organisations had a strong sense of what was meant by environmental responsibility, less was known about what was required to be socially responsible.

Research Report 515 - The effect of rainfall and contaminants on road pavement skid resistance

Published: | Category: Environmental impacts of land transport , Research programme , Research & reports | Audiences: Communities, General

This research project, which was undertaken between 2003 and 2006, aimed to improve the understanding of the effect that environmental factors (eg rainfall and detritus) have on the variation of measured skid resistance, both in the short and longer term. Phase 1 of the research was a field study of seven sites in the Auckland and Northland regions over 2.5+ years, with regular skid resistance measurements primarily utilising the GripTester. Phase 2 involved developing a new laboratory-based accelerated polishing device and methodology for testing large (600 x 600mm) chipseal surfaces with the Dynamic Friction Tester.

Research Report 288 Assessment of hazard warning signs used on New Zealand roads

Published: | Category: Safety, security and public health , Research programme , Research & reports | Audience: General

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, schools, slippery surfaces and curves. Conclusions are presented about the effectiveness of hazard warning signs, and the method for evaluating new and existing hazard warning signs used on New Zealand roads. Keywords: crashes, driver behaviour, hazards, risk, road accidents, road signs, roads, traffic, vehicles

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

Published: | Category: Safety, security and public health , Research programme , Research & reports | 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 401 Rationalisation of the structural capacity definition and quantification of roads based on falling weight deflectometer tests

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

Pavement performance modelling for New Zealand roading networks, currently relies on an adjusted structural number (SNP) which is a single parameter intended to describe the performance of a multi-layered pavement structure in terms of its rate of deterioration with respect to all structural distress modes, as well as non-structural modes. This parameter had its origin in the AASHO road test in the late 1950s, before the advent of analytical methods. Hence refinement to keep abreast of current practice in pavement engineering is overdue. This research describes the basis for a new set of structural indices and how these can be used to obtain improved prediction of pavement performance: both at network level and for project level rehabilitation of individual roads. The results are (i) effective use of all the data contained in RAMM, (ii) more reliable assignment of network forward work programmes, (iii) reduced cost through targeting only those sections...
