Research Report 018 Land transport pricing for New Zealand

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

As part of the management of the land transport system of New Zealand, a study of land transport pricing policies, with particular emphasis on road pricing, has been carried out. The study comprised a review of relevant literature and the development of a proposed land transport pricing research programme for New Zealand. The report of this study consists of three parts:

a description of the current structure and pricing of land transport infrastructure in New Zealand
a review of the literature on land transport pricing to identify the principles underlying transport pricing policies and current and proposed policies from other countries, and
the identification of a proposed land transport pricing research programme for New Zealand.

Research Report 310 The safety benefits of brighter roadmarkings

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

Since about 1997 the brightness of roadmarkings on a number of New Zealand state highways has been increased. This study was undertaken to determine whether an increase in safety, as measured by reduced crashes, could be associated with the use of these brighter roadmarkings. Keywords: curve, delineation, edgeline, edgemarker, ratio, reflectivity, regions, retroreflectivity, roadmarking, road safety, statistical analysis, straight, visibility

Research Report 242 Harmonising automated rut depth measurements

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

A computer simulation study was conducted to investigate the viability of harmonising rut depth measurements from different automated rut depth measurement profilometers. A computer program was written which allowed for a standard reference transverse profile to be analysed by any number of profilometer sensors and spacings. The software generated a variety of rut depth statistics. The software was used to investigate the effect of the number of sensors on the predicted rut depth. It was found that the accuracy of the rut depth was proportional to the number of sensors and that this sampling effect results in an underestimation of 2–4 mm for the profilometers used in NZ. The pseudo-rut model was found to be inappropriate for predicting rut depth. It did not prove possible to test the wire model due to the shape of the reference profiles.

Research Report 375 Applying health impact assessment to land transport planning

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

This research draws on learning from New Zealand and other countries to meet the following research objectives:

to assess the need for health impact assessment (HIA), in the context of the New Zealand Transport Strategy and relevant legislation
to evaluate the role of HIA in land transport planning to date in New Zealand and explore barriers to the use of HIA
to understand the best point(s) for application of HIA within the New Zealand transport sector
to produce recommendations for better integration of HIA with other development processes in the transport context. Three data collection components were undertaken between September 2008 and January 2009:

an international literature review
a descriptive review of transport planning processes in New Zealand
four case studies examining application of HIA transport in New Zealand. Findings indicate deficiencies in current assessment processes and a need for HIA.

Research Report 243 An integrated traffic model for Auckland cities

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

This study carried out in 1999–2002, attempted to demonstrate and quantify benefits of an integrated approach to traffic signalisation and management of urban street networks that straddle boundaries of Transit New Zealand and Local Authority jurisdictions. A methodology based on two traffic simulation computer models, TRANSYT11 and AIMSUN2, was tested. Salient aspects of the methodology are discussed and relevant issues identified. The methodology was applied to an assessment of the performance of a street network in the Auckland region (Manukau City), New Zealand. The analysis predicted potential improvements were achievable when one of the traffic management improvement techniques was used.  However, because of the large number and complexity of developmental issues, and the incompatibility of the two programs, the methodology was assessed as unsuitable as a practical tool for local road controlling authorities. Keywords: AIMSUN2, modelling, New Zealand, road, safety, traffic, traffic control, traffic models, TRANSYT11, VISSIM, VISUM

Research Report 311 Energy risk to activity systems as a function of urban form

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

This project aimed to develop analytical methods for assessing energy risks due to a peak and decline in global oil production. Additionally to develop modelling capabilities to link these analyses to urban form. The aim was to provide a new capability for long term development planning. The need for communication between members of the community, councillors and practitioners with diverse backgrounds and interests are realised. Thus, the goal in modelling was to provide accurate risk assessment and clear visual-based communication of results. Keywords: energy, urban form, transport policy, modelling.

Research Report 309 Trials of the use of recycled hot mix and ground tyre rubber in hot mix asphalt

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

This research, carried out in 2003–2004, aimed to facilitate the recycling of asphalt mix, recycled asphalt pavement (RAP), and crumb rubber (CR) from waste tyres into New Zealand roads. The objectives were to allow for the revision of the appropriate specifications to encourage recycling of these materials and to use field trials to prove the performance of recycled and crumb rubber modified mixes in practice. Keywords: asphalt mix, crumbed rubber, hot mix, recycled asphalt, recycled rubber, roads, trials

Research Report 044 Heavy transport routes: their identification and evaluation of a pilot route

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

An investigation into the feasibility of increasing the legal loads for heavy vehicles on New Zealand roads was begun in 1993. Roads carrying major flows of heavy vehicles in both the North and South Islands were identified, and those that have potential to be used as heavy transport routes were selected. These are routes that carry significant flows of heavy vehicles, and that have a clear purpose (eg mill to port). To evaluate the potential for increasing the legal gross weight of heavy vehicles that could be carried on these heavy tranport routes, the route between the wood-pulp mill at Kinleith, near Tokoroa in the centre of the North Island, and the Port of Tauranga on the Bay of Plenty, was taken as a pilot. The main concern was to evaluate the road geometry and vehicle weight constraints of the pavements and bridges along the pilot route.

Research Report 376 Agglomeration elasticities in New Zealand

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

This paper analyses the relationship between the multi-factor productivity of New Zealand businesses and the effective employment density of the areas where they operate. Quantifying these agglomeration elasticities is of central importance in the evaluation of the wider economic benefits of transport investments. We estimate that firms in an area with 10% higher effective density will have productivity that is 0. 69% higher, once we control for industry-specific production functions and the sorting of more productive firms across industries and locations. We present separate estimates of agglomeration elasticities for specific industries and regions, and examine the interaction of agglomeration with capital, labour and other inputs.

Research Report 031 User perceptions of the New Zealand state highway system

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

This report is of market research into the perceptions and views of road users about the state highway system in New Zealand. The research involved group discussions, a household survey and a survey of commercial road users. It investigated users' rating of the importance of 24 attributes of the state highway system and their assessment of the performance of the existing system against each attribute. It covered perceptions both of the state highway system as a whole and of particular routes. The report highlights those road attributes which users rate as important but for which, they consider, the present system performance is inferior. These are the attributes that warrant high priority for attention by Transit New Zealand.
