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 521 An investigation into the deployment of an advisory ISA system in New Zealand

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

Excessive and inappropriate speed on our roads is a significant issue in New Zealand, and loss-of-control crashes, on rural curves in particular, are a key crash contributor. This research investigated the deployment of an advisory intelligent speed adaptation (ISA) system in New Zealand.
