Research Report 656 Evidential basis for community response to land transport noise

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

Environmental noise caused by road and rail traffic can cause a range of disturbance and annoyance reactions amongst local communities.

Research Report 654 Social and distributional impacts of time and space-based road pricing

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

This report outlines a general framework that can be used to analyse the social and distributional impacts of road pricing in the New Zealand context and applies it to two hypothetical case studies of road pricing schemes in New Zealand cities.

Research Report 655 Performance benefits of polymer modified bitumen binders for thin surfacings

Published: | Category: Resilience and security , Research programme , Research & reports | Audience: General

Research was undertaken at WSP Opus Research in 2018 to investigate evidence from field studies supporting the performance benefits of polymer modified binders (PMBs) in thin asphalt and chipseal road surfacings. Improved performance benefits claimed for the use of PMB modified thin surfacings include reduced rutting and fatigue cracking in dense asphalt, reduced chip loss in chipseals and open graded porous asphalts and reduced flushing in seals.

Research Report 652 Assessment process for the condition of unsealed roads

Published: | Category: Resilience and security , Research programme , Research & reports | Audience: General

Unsealed roads remain the backbone of the New Zealand’s economy. Less than 40% of local roads in New Zealand are sealed, yet most of New Zealand’s farm produce, important tourism and forestry harvest start their journey to the international market on unsealed roads. It is therefore essential to plan the investment into this network based on appropriate data.

Research Report 653 Extension of NZ Transport Agency Research Report 629: System dynamics investigation of freight flows, economic development and network performance

Published: | Category: Economic development , Research programme , Research & reports | Audiences: Heavy vehicle operators, Road traffic engineers & consultants

In 2017 we developed a system dynamics model to study inter-regional freight and traffic flows in the Auckland–Hamilton–Tauranga triangle. Here we extend the model northward to Whangarei in order to incorporate Northport. This enables us to provide an order of magnitude estimate of how many truck movements might be required to transport freight between Auckland and Northport, if most or all of the exports and imports that currently pass through Ports of Auckland were to enter and leave New Zealand via Northport instead.

Research Report 650 Understanding current and forecast visitor flows to the South Island

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

Data is required for destination management, both of current visitor activity and future activity. This report reviews the data that currently exists for visits to the South Island of New Zealand, where tourism growth has been, and is still expected to be, strong. Not surprisingly no one dataset was found that could reasonably describe visitor activity, nor were there forecasts for core visitor activities across each region of the South Island. Methods were tested to show how currently available data, including an International Visitor Survey and a measure of electronic card spending, could be adjusted to derive measures of visitor presence.

Research Report 649 Great Kiwi road trips: enhancing New Zealand’s tourism industry through better visitor journeys

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

The purpose of this study was to gain a better understanding of the expectations, motivations, experiences, information preferences and behaviour of visitors (both domestic and international) travelling on New Zealand’s transport network.

Research Report 645 Post-impact care: How can New Zealand address the fifth pillar of road safety?

Published: | Category: Safety, security and public health , Research programme , Research & reports | Audiences: General, Medical practitioners, Road controlling authorities

Post-crash care of victims is considered by the World Health Organisation to be the fifth pillar of the safe system approach to road safety. Timeliness and quality of transport of crash victims from the crash site to hospital door is crucial to medical outcomes. It is important that road controlling authorities (RCAs) and Road Policing work together with Emergency Services to provide the best possible outcomes for the available resources.

Research Report 643 Drivers’ response to warnings/information provided by in-vehicle information systems (IVIS)

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

The purpose of the research was to provide an analysis of drivers’ use of IVIS, smartphone applications and nomadic devices and their likely effects on driver performance.

Research Report 644 The crash performance of seagull intersections and left-turn slip lanes

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

A number of alternative intersection layouts are used around the country to reduce traffic delays and to improve road safety. One such group of alternative intersections are termed ‘priority controlled seagull intersections’.
