Research Report 486 Travel adaptive capacity assessment for particular geographic, demographic and activity cohorts
Published: Jul 2012Transport infrastructure and network planning must now consider oil shocks and future demand growth for more energy efficient transport modes. However, data and models for this type of fuel reduction planning are not available. Travel adaptive capacity is proposed as a measure of the resilience of travel demand to a reduction in fuel use for personal vehicle trips while not reducing participation...
Research Report 432 Minimum design parameters for cycle connectivity
Published: Jun 2012This research used video surveillance of 1245 cyclists in New Zealand at pinch points to determine the relationship between the remaining lane or shoulder width and the likelihood of cyclists traversing the edge line into the motorised vehicle stream. Ten sites were observed in Wellington and nine in Christchurch. Sites were selected on the criteria of retained cycle space widths at short pinch...
Research Report 456 Improved rate-of-rotation design limits
Published: Oct 2011Rate of rotation, or 'warp factor' is a measure of the variation in crossfall of a road surface, and typically relates to a change in crossfall from that of a normal straight road to that chosen for a curve to enhance forces assisting a vehicle to stay on the road. The range of road geometries (crossfall, curvature, transition length and superelevation) typically found on the state...
Research report 407 Evidential-based guidelines for temporary speed limits
Published: Oct 2010A study was conducted to examine whether the New Zealand Code of practice for temporary traffic management guidelines for the implementation of temporary speed limits (TSL) result in driver speeds that match safe travelling speeds. Site approach and site entry speed data was collected at eight sites around Wellington, New Zealand, where TSLs were in place. Four TSLs (100 to 70km/h, 100 to 50km/h,...
Research report 402 Development of indicators for monitoring land use transport integration projects
Published: May 2010This report sets out the process needed to develop a monitoring framework for integrated land use and transport projects. The report maintains that each project will need a unique set of indicators that reflect the specific outcome objectives for the project. The monitoring framework is therefore 'policy neutral', interpreting integration as a process rather than an outcome in itself....
Research report 398 Utilisation of the kerbside through-lane at signalised intersections
Published: Apr 2010Lane under-utilisation is commonly experienced at signalised intersections. This has significant effects on intersection capacity, which has consequences for congestion, especially in the urban environment. Ultimately, this results in overly optimistic design predictions. Little research has been undertaken in New Zealand and Australia on this topic. The main focus of this study was to determine...
Research report 399 Kilometres travelled and vehicle occupancy in urban areas: improving evaluation and monitoring
Published: Apr 2010This report lays some foundations for improving how interventions (eg travel plans) are evaluated and monitored in cities. The main data source used is the New Zealand Household Travel Survey (HTS). Some Census results on distances between home and work are a useful complement.
Distance travelled to work in main urban areas (ie urban areas with populations of 30,000 or more) is a...
Research report 400 Minimising traffic delays during resealing
Published: Apr 2010This research demonstrated that:
• racked-in seals can handle the stress of high-volume traffic
• racked-in seals can be constructed in an eight-hour working period including any sweeping and road marking
• closely controlled chip application rates result in minimal loose chip on surface
• minimal loose chip results in minimal chip being flicked by...
Research report 397 Framework for a National ITS architecture
Published: Mar 2010The New Zealand intelligent transport systems (ITS) framework architecture was developed between 2007 and 2010 by Hyder Consulting Ltd for the NZ Transport Agency. It forms the basis on which to describe best practice development of a full ITS architecture for New Zealand consisting of a reference architecture, logical architecture and physical architecture. This will include a range of major...
Research Report 390 The waterproofness of first-coat chipseal
Published: Sep 2009This research project, undertaken in 2006 to 2008, confirms that traffic can force water through first-coat chipseal surfacings that do not visually show signs of cracking. The research measured the change in moisture content after rain on a number of newly sealed sites. Although this testing showed a statistically significant increase in moisture over all sites, the increase was not dramatic....
Research Report 346 The effectiveness of incident management on network reliability
Published: Jun 2008This report summarises preliminary research undertaken in New Zealand during 2006–07 to investigate the ability of intelligent transport system (ITS) treatments, such as adaptive signal control (eg, SCATS) and variable message signs (VMS), to detect and respond to serious traffic incidents, and to determine the most appropriate traffic management strategies (in terms of overall network...
Research Report 317 ITS environmental monitoring and forecasting: International trends and experiences
Published: Mar 2007The purpose of this project was to review the use overseas of environmental monitoring and forecasting systems as a component of wider-integrated ITS facilities, in particular those linked to transport and traffic management, and to consider their potential for New Zealand. It also aimed to provide direction from overseas best practice on the use of these systems to monitor, forecast and manage...
Research Report 320 Impact of urban form and other characteristics on the implementation of urban road pricing

Through the evaluation of the international systems, this...
Research Report 301 Best practice for use and design of truck mounted attenuators (TMA) for New Zealand roads
Published: 2006Truck Mounted Attenuators (TMA) are widely used on New Zealand Level 2 and 3 state
highways and on some network roads that carry high-volume high-speed traffic, to
provide safe environments for both roadwork crews and road users. They are used for
static, semi-static and mobile operations carried out on sealed carriageways.
However, current practice (specified in the 3rd...
Research Report 297 Through lane utilisation at Traffic Signals
Published: 2006Research was undertaken during 2004/05 to determine the effect of short approach through-lanes and downstream merges on lane use at signalised intersections, and to find ways of improving use. This involved surveying three intersections.
In general, short slip lanes and short approach and departure through-lanes cause short through-lanes to be used less. Accordingly, a guide was...
Research Report 302 Intelligent Transport Systems: What contributes best to the NZTS objectives?
Published: 2006The purpose of this study has been to document international experience of where the
greatest benefits have been gained from the implementation of Intelligent Transport
Systems (ITS), and to compare these benefits with the key outcomes sought in the New
Zealand Transport Strategy (NZTS) and Land Transport Management Act (LTMA).
The resulting report provides guidance on the...
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...
