How effective are transport-related ecological interventions? |
Wildland Consultants Ltd |
November 2024 |
Purpose and objectives: |
The purpose of this research is to assess the following for roading projects in New Zealand:
A Gap analysis will be undertaken that assesses the ‘state of play’ of roading ecological interventions. The Gap analysis will also identify the residual between what ecological interventions are achieving and what they are required to achieve to meet obligations under the Resource Management Act (1991) and the Wildlife Act (1953). This research will address the knowledge gap around the effectiveness of ecological interventions made by the transport sector when carrying out infrastructure projects and maintenance and operational activities. The magnitude and severity of an impact on ecological values depends not only on the nature of the roading or activity project but also on the effectiveness of the interventions implemented. The first objective of this research is to review what the known ecological effects of roading projects have been in New Zealand since (and including) the Northern Gateway project. This will include reviewing the nature, extent and success of ecological interventions undertaken to remedy, mitigate ecological effects. The review will consider:
The second objective of this research is to use data from the review in a Gap analysis that will determine the actual performance of ecological interventions. This will be assessed against ecological criteria, and within the context of the Resource Management Act (1991). |

Evaluating different approaches to Low Emission Zones around the world |
Beca |
November 2024 |
Purpose and objectives: |
This research will provide directly transferable evidence to New Zealand, on how different cities around the world have implemented Low and Zero Emission Zones and the advantages or disadvantages of the different approaches. The 2016 study of Health and Air Pollution in New Zealand found that just over 80% of New Zealanders are exposed to poor quality air, with persisting higher rates for Pasifika New Zealanders. As New Zealand becomes increasingly urbanised more and more people are likely become exposed to poor air quality from vehicle emissions. Low emission zones have been an effective tool in improving air quality and people's health in a number of cities across the world, there are hundreds of examples across many countries in Europe and Asia that we can learn from to develop our understanding and craft appropriate legislation. To make the most out of this important research project, it is important to establish and agree clear objectives. We have grouped the knowledge gaps and study objectives described in the Consultancy Service Order into four areas: Health, Climate, Social and Design. Each with the objectives as set out below. Health: To understand the effectiveness of low emission zones as a tool to target better outcomes for peoples’ health. Climate: To understand the effectiveness of low emission zones as a tool to target environmental impacts. Social: To understand levels of public acceptability / social license to low emission zones as well as how equity aspects have been considered. Design: Distil the lessons learnt regarding development, design, implementation and monitoring of schemes, including advantages and disadvantages of charging emissions intensive vehicles from low emission zones versus prohibiting access. |

Noise disturbance from individual vehicles |
Altissimo Consulting Ltd |
December 2024 |
Purpose and objectives: |
Our research will deliver a better understanding of the significance of noise from individual vehicles compared to average levels from steady traffic, and how road layout features influence noise generation. We will establish a consistent framework for monitoring, assessing, and predicting individual vehicle noise and other nuisance noise. This framework will assist Waka Kotahi to assess projects and design elements on a consistent basis. This framework will also allow for the implementation of appropriate interventions to reduce effects. The result of this improved understanding and assessment framework will be to more effectively evaluate and design roading features, such that noise effects will be reduced. The reduced noise effects will result in improved amenity for residents near roads, and a reduced risk of health effects from road-traffic noise, particularly sleep disturbance. The end goal of our research is to provide Waka Kotahi and the wider community with better knowledge and tools resulting in is reduced harm and a better living environment for people adjacent the state highway network. The first objective of our research is to summarise known issues of noise from engine braking, and vehicles driving over bridge joints and Audio Tactile Profile (ATP) linemarking. This objective will yield an understanding of the prevalence and effect of these noise sources. This will largely be performed by a meta-analysis of existing NZ studies, and will be supplemented with the measurement results in this research project. The primary mechanisms resulting in these noise events are understood, but the evidence needs to be collated and formalized to inform decisions and policy. The second objective of our research is to address the lack of standardized approaches for predicting the level or impact of sounds from individual vehicles and sound arising from surface features. We understand that this research should address noise from vehicles traversing road design features such as:
and noise from road surface features such as:

Methods for measuring mode share and mode shift at different spatial and time scales |
ARRB Group Ltd – National Transport Research Organisation |
October 2024 |
Purpose and objectives: |
Knowledge gap A review of a range of current cost-effective methods that can be implemented to robustly measure person-kilometres travelled by mode share and mode shift at a greater resolution (time, spatially and trip purpose) than currently possible to monitor transport system changes is needed. Purpose This will enable the creation of a bespoke integrated toolkit for improved mode-share measurement that will assist with many transport output and outcome measurements, such as modal emissions and risk-exposure per mode. Objectives This research will identify the most appropriate methods for measuring person-kilometres travelled mode shift and the underpinning mode share at sub-national spatial and short time scales. The objectives of the research are to: a. identify and develop methods for measuring mode shift and mode share that are responsive to regional and local scale interventions, b. identify and develop methods for measuring mode shift and mode share at these spatial and time scales across all journey types and modes, c. quantify the uncertainty and/or confidence intervals, and d. combine the research into an integrated mode share and mode shift measurement toolkit. These objectives need to be viewed in the broader context of moving people efficiently on our transport networks across all modes (in particular road and rail), while managing congestion and costs, and achieving emission targets. |

An enhanced, nationally consistent, travel mode choice model |
Data Analysis Australia Pty Ltd |
December 2024 |
Purpose and objectives: |
Public Transport (PT) and active travel modes among network users are considered the most sustainable and low carbon form of ways to travel among locations. However, Waka Kotahi NZ Transport Agency identified that the current national transport model does not forecast PT and walking and cycling uptake during investment planning phases—with consequent uncertainty as to the outcomes of these metrics. Behavioural variables, such as attitude, improved the predictive validity of disaggregate choice models (Ben-Akiva et al., 1999). Many latest studies have found that attitudes are strong predictors of the chosen travel mode, even stronger than, for instance, the built environment and residential location (De Vos et al., 2016; Hess et al., 2018; Ton et al., 2020). However, limited transport models have included such behavioural variables, and if included in current modelling, tend to rely on fuzzy estimations only, thereby impairing their predictive power. Moreover, current evidence suggests that contemporary modelling tends to be precise but not necessarily accurate when it comes to predicting travel mode choices in the future. Emerging science and transport psychology offer the prospect of substantively improving modelling and forecasting, providing more informed investment planning and decision-making. The knowledge gaps of current transport models recognised by the Waka Kotahi NZ Transport Agency as follows: 1. Current regional-level models have limited mode share capability and there is no evident standardised approach for modelling, data collection, or accuracy requirements, either in Aotearoa/New Zealand or internationally. 2. The vast majority of mode choice modelling focuses only on: i. single-trip ii. single-mode iii. single-trip-purpose, and iv. single-person-type 3. Therefore, often omitting multi-leg, multi-purpose journeys and a broad spectrum of users. 4. Interviews with practitioners and analysis of existing models revealed that behavioural variables are often only fuzzy estimations due to a historic dearth of behavioural data. 5. Finally, a reliance on generalised costs elements of time, distance, and financial cost with elements such as transfer penalties provide only coarse calibration—while simultaneously omitting substantive user-related variables that verifiably have an influence on travel mode choice. Our team brings together experts on transport, psychology of decision-making, discrete choice modelling, and data analysis, and covers scales from individual people to systems. Our goal is to use this expertise to build a “joined together” hybrid model that uses robust objective and psychological variables to predict journey choice. A key consideration is how people make choices involving multi-mode journey options, where there is the potential for complex interactions or trade-offs between factors: a journey involving cycling may not be preferred by the same people who like to cycle if an automobile is involved and conflicts with attitudes to cars. To fill in the knowledge gaps discussed above, we propose the following research objectives: 1. Develop a review of the current and emerging scientific and transport literature pertaining to the substantive drivers or variables behind travel mode choice as they apply to: i. multi-modal, multi-leg, multi-user journeys, and critical journeys ii. interaction effects among these variables. 2. Develop a rationalised set of data inputs is required, in addition to a critique of said inputs that may be used to enhance future data quality and data gathering efforts. 3. Develop standardised procedures that enable actors around Aotearoa/New Zealand to coordinate efforts and share comparable findings. |

Establishing a methodology for integrated transport accessibility measures |
Principal Economics Ltd |
December 2024 |
Purpose and objectives: |
The purpose of this proposed research is to inform the establishment of a methodology for creating an integrated, multi-modal, multi-destination spatial accessibility measure, based on current infrastructure, demographics and destination-based accessibility, to replace vehicle mobility-based measures. The methodology should be applicable to both the current conditions of transport accessibility and scenario testing for evaluating different options. Below are listed the objectives of the research and the high-level approach. The project will proceed in two stages. The objectives are to: Stage one: a) Review national and international literature and experience of accessibility measures in transport. b) Identify typical accessibility datasets used in urban areas worldwide, which may not be readily available within New Zealand, and suggest other approaches to measurement which may be adopted in short and long terms. c) Identify how active-mode network analytics could consider levels of service and desirability of links, given the data sets currently available in New Zealand; d) Explain the various ways live and static General Transit Feed Specification (GTFS) files have been used overseas (and in New Zealand) to inform aspects of spatial accessibility (with more of a focus on connectivity rather than PT performance-analytics). Stage two: e) Identify weighting and calibration factors for saturation curves to quantify diminishing additional benefit of reaching more destination-types; f) Use modal reach curves to quantify how far people are willing to travel in different New Zealand contexts to reach different destination types; g) Develop appropriate weighting for integrating different destination types into measures which take the price of land and transport into account and represent the 'value' of reaching different destination types for different population groups. h) Inform production of a toolkit (being developed in parallel by Waka Kotahi) that will enable assessment and measurement of accessibility based on a wide range of measures, in addition to access to employment, at all levels of the transport system. |

The demographics of Vehicle Kilometres Travelled (VKT) |
Principal Economics |
February 2025 |
Purpose and objectives: |
The purpose of this research is to gain a comprehensive understanding of the motor vehicle profile of households across New Zealand, focusing on their demographic and spatial characteristics in relation to Vehicle Kilometres Travelled (VKT), emissions, and safety outcomes. The research aims to inform VKT reduction initiatives, transport policies, and decision-making at national, regional, and local levels. The study will use data from the Integrated Data Infrastructure (IDI), Household Travel Survey (HTS), and Motor Vehicle Register (MVR) to derive statistical models that can help design and target policies and activities for reducing light vehicle kilometres traveled (VKT) and achieving sustainable transport outcomes. The resulting dataset from the research project will feature data on household demographics, vehicle ownership and usage patterns, GHG emissions, and related variables. We will work with Te Manatū Waka and the client teams in using this dataset as an input to generate the synthetic dataset (SURF) to serve as a cross check against Te Manatū Waka Monty outputs. The research will compare and review the spatial distribution of VKT, emissions, health impacts and safety profiles derived from this analysis with relevant existing models, i.e. HAPINZ and VEMT The research will proceed in two stages, with a continue or stop decision to be made at the end of stage one. The objectives of the research project are as follows: Stage one a. Review existing studies by Te Manatū Waka, Waka Kotahi, and other published sources to analyse residential/private light VKT and identify best practices for modelling and allocating light VKT. b. Identify the range and variances of household and individual demographic characteristics that can be extracted from the IDI and the Household Travel Survey (HTS) data for analysis and link them to vehicle ownership, use, and GHG emissions. Stage two c. Link odometer readings (VKT) to personal and household demographics while maintaining privacy and anonymity of records adhering to Statistics NZ IDI Five safes framework and confidentiality rules. d. Leverage the MVR to create a comprehensive fleet VKT/GHG profile regionally for use in the VEPM. e. Derive associations between demographics of VKT and GHG emissions, including safety and emissions profiles of households. f. Evaluate the safety profile of the vehicle fleet in terms of star ratings and compare it to regional DSI rates to identify areas where interventions may be necessary to reduce the risk of trauma. g. Use HAPINZ air quality health data to record health conditions due to transport emissions spatially as a layer and integrate it with the Vehicle Emission Mapping Tool (VEMT). h. Derive spatial and regional calculations of VKT emissions (CO2, NOx) for different demographic characteristics of households and compare them to official type-approval emissions profiles in Right Car. i. Create statistical models that link the main characteristics and impacts of people, households, location, vehicles, and vehicle use associated with patterns of VKT, including high-growth VKT. j. flexible outputs that can be input into a SQL database and include an accessible Synthetic Unit Record File (SURF) using a statistical model to be specified by Te Manatū Waka and the synthpop R package. |
