A First Examination of Cost-of-Living Concern, Neighbourhood Perceptions, Active Travel, and Wellbeing in Cities Beck, Matthew J.; Greaves, Stephen This paper is a first step in the literature, looking at potential links between cost-of-living stress and the perceptions of local neighbourhoods, under the hypothesis that greater pressure about housing affordability, transportation costs, or indeed cost-of-living overall could lead to a degradation in how the neighbourhood within which a person lives is perceived. We find confirmation that cost-of-living goes beyond technical measures of housing stress and indeed beyond just housing stress alone. Of relevance is that those who could be classified as having rising concern (consumables) have among the highest levels of relative stress. We find that there is generally just as much concern about the rising cost of fuel, which is directly related to trip making, further compounding transport accessibility and equity. Overall, our first attempt to investigate the potential nexus of cost-of-living, neighbourhood perception, wellbeing, physical activity and active travel, produces enough evidence and insight to establish that there are potential links which are likely to play out in unknown ways during cost-of-living crises. We argue that our results are sufficient enough that research should extend them to transportation costs and trip making more generally and urge other researchers to consider building on these insights.

An analysis of increasing petrol prices on travel behaviour Pellegrini, Andrea; Beck, Matthew J.; Rose, John M. This paper examines how rising petrol prices affect weekly travel behaviour, with particular attention to modal substitution and trip suppression. The analysis draws on stated responses from 808 Queensland residents, each of whom first reported their travel behaviour for the week prior to the survey and then indicated how that behaviour would change under three hypothetical petrol price scenarios set at AUD 2.50, AUD 3.00, and AUD 3.50 per litre (noting fuel prices at the pump varied between an average of AUD 2.20 and AUD 2.53 during the survey period). Weekly trip frequencies are jointly modelled for eight travel outcomes, including car travel as driver, car travel as passenger, public transport, taxi, rideshare, cycling, walking, and avoided trips. The latter category is included within the hypothetical setting to capture the extent to which increase in petrol prices may lead travellers to cancel or forgo trips altogether, rather than simply reallocate travel across modes. The empirical analysis is performed implementing a multivariate Generalised Poisson framework with dependence across travel alternatives introduced through a Gaussian copula. The results indicate that higher petrol prices substantially reduce car travel both as driver car passenger, while increasing public transport use, particularly at the higher price scenarios. However, the substitution towards public transport is only partial. A sizeable share of the adjustment instead occurs through avoided trips, suggesting that fuel price increases are more likely to suppress travel rather than simply induce a reallocation across modes. The findings further show that behavioural responses vary with socio-economic circumstances and perceived transport disadvantage, implying that the burden of higher fuel prices is unevenly distributed. Overall, the paper shows that rising petrol prices affect not only mode choice, but also the ability of individuals to maintain everyday mobility and activity participation.

The global conflict in the Middle East is having a significant impact on the availability of oil to many countries, with Australia feeling the impact more than most countries. Fuel prices escalated during the first three weeks of the war (up to the end of March 2026), typically being 30-50% higher than the retail prices at the pump under normal market conditions. Supply uncertainty has also created problems in distribution, especially for farmers, trucking companies and retail outlets. In response to the escalated fuel prices at the pump, the Federal government announced, on 31 March, a reduction in fuel excise for three months (from 52.6 to 26.3 cents per litre) with state and territory leaders agreeing to pass on the additional goods and services tax windfall to motorists (further reducing the total to 20.6c/litre as well as the removal of the heavy vehicle road user charge for the same period (the latter of 32.4 cents per litre is reduced to zero). This paper explores ways in which users of passenger cars have responded to these price hikes and supply uncertainty. A series of questions incorporated in a survey of 1,000 New South Wales (Australia) residents in the first two weeks of April 2026, up to a temporary ceasefire and US blockage of the Strait of Hormuz, sought evidence on behavioural change responses such as modal switching for work and non-work-related travel, changes in car kilometres, car sharing, working from home, purchase of an electric or hybrid vehicle, and switching car use between petrol/diesel and electric vehicles in the current household fleet. These responses are embedded in a number of scenarios that vary fuel prices and fuel scarcity (availability and rationing) to assess the likely behavioural response in the short run and in the longer run if a scenario becomes reality. Overall, the key policy takeaway is that fuel pricing is most effective as a short run signal and selective rationing tool, while long run resilience depends on structural adaptation, especially vehicle technology, income buffering, and access to substitutes.

Trust and Legitimacy in a Contentious Policy Change Beck, Matthew J. This paper examines public responses to the introduction of paid visitor parking as a contentious local policy change in a tourism-dependent region. While parking pricing is widely recognised as an effective tool for managing demand and generating revenue, less is known about how such policies are interpreted and legitimised by affected communities. Using the Blue Mountains in New South Wales as a case study, the study treats the introduction of paid parking as a natural experiment in user-pays reform under conditions of infrastructure funding pressure and climate-related disruption. A mixed-methods approach is employed, combining survey data, factor analysis, clustering, and qualitative thematic analysis to identify patterns in attitudes and interpretation. The findings show that acceptance is not primarily driven by demographic characteristics or behavioural exposure, but by institutional trust, beliefs about collective responsibility, and perceptions of governance quality. Three distinct attitudinal segments are identified, reflecting differing configurations of support, trust, and normative beliefs. Despite the scheme’s demonstrated effectiveness as a revenue-generating instrument capable of supporting substantial infrastructure investment, public acceptance remains contested. The policy is frequently interpreted through a “revenue raising” frame, particularly where trust is limited. The paper argues that parking pricing operates not only as an economic instrument but as a governance signal, with legitimacy contingent on transparency, fairness, and the visible reinvestment of revenues.

Declining revenue from traditional road funding sources, rising infrastructure costs, and the transition to electric vehicles have increased the urgency of road user charging reform as a key demand management strategy. While such schemes can improve transport system efficiency by pricing congestion and other externalities, their implementation requires careful balancing with concerns around fairness and affordability. Public acceptability therefore remains a critical constraint on policy adoption. This paper examines which policy features most strongly influence support for road user charging and how these preferences can inform the design of policies that advance efficiency, fairness, and affordability objectives. A best worst scaling approach is used to elicit the relative importance of policy features, with choices modelled using a hybrid choice framework that captures both observed preferences and underlying attitudes. Three distinct behavioural classes are identified, reflecting differing priorities related to efficiency, fairness and consistency, and broader public benefit. Across these groups, governance and institutional arrangements are central to perceived legitimacy. Features such as public ownership, not for profit operation, independent investment decision making, and transparent revenue use are strongly preferred, while more complex pricing mechanisms are viewed less favourably. The findings highlight the importance of trust, fairness, and affordability in supporting effective and acceptable reform.

This paper draws on insights from a series of expert roundtable discussions involving stakeholders from government, industry organisations, and research institutions with the primary objective of gathering multidisciplinary perspectives to inform the development of an overarching conceptual framework that supports the design of context-sensitive and effective behaviour change interventions. Themes emerging from the discussions were critically reviewed and mapped to relevant behavioural constructs such as attitudes, perceived behavioural control, subjective norms, and intention. The ensuing framework synthesises theoretical foundations from established behaviour change models with real-world experiences in the transport domain, offering a structured lens through which to interpret the drivers and barriers of behavioural shifts. Key insights that emerged include the critical role of overarching policies and goals enabled through collaborative governance, the need for inclusive and user centred interventions aligned with personal and societal benefits and the need for stakeholder collaboration within and across different sectors. By presenting evidence-informed recommendations and a cohesive conceptual framework, this paper offers a foundation for advancing sustainable transport through targeted and systemic behavioural change initiatives.

This paper addresses that gap by estimating a single choice framework that spans new and second-hand passenger vehicle markets, allowing direct comparison of how consumers value vehicle attributes and how substitution patterns differ across the two segments. We use a discrete choice experiment administered to a New South Wales sample, with alternatives that include new and second-hand vehicles and an opt-out, and attributes that reflect both markets, including purchase price, body type, vehicle size, powertrain, range, delivery availability for new vehicles, and odometer and condition for second-hand vehicles. Preferences are estimated using a two-class latent class model with error components to capture correlation in unobserved utility and segment-specific substitution within new and second-hand markets. The results show substantial heterogeneity in valuations and clear differences between new and second-hand decision processes, with second-hand quality signals exerting economically meaningful effects and price sensitivity being stronger for second-hand choices. Powertrain attributes matter, but their implications vary by market segment and by class, indicating that technology preferences interact with the institutional and informational features of the market in which the vehicle is acquired. Applying the estimated class-membership model to population microdata, we generate conditional parameter and willingness-to-pay distributions for a large synthetic population and predict market shares for simulated vehicle profiles. The simulation results underscore that secondary-market dynamics materially shape predicted demand patterns, which has implications for policies and market designs that aim to influence fleet composition through interventions that operate in, or propagate through, the second-hand market.

The objective of this study is to examine how electric vehicle (EV) owners perceive a range of post-purchase issues that are relevant to EV adoption. Using a nationwide sample of 1,794 Australian EV owners, we analyse the importance assigned to seven post-acquisition concerns: range anxiety, public charging availability, charging duration, upfront price and value for money, model availability and consumer choice, trust of new technologies, and battery fire safety. The empirical findings suggest that there exist differences across EV users in terms of socio-economic factors, home charging infrastructure factors and vehicle characteristics with respect to the seven rating dimensions. Further, post-purchase concerns appear to be highly positive interdependent, particularly regarding charging infrastructure, technological trust and safety, and financial aspects. Finally, simulation results show that public charging infrastructure remains highly important, even if all respondents are assumed to have access to solar panels for EV charging activities.

The ultimate purpose of such interventions is often improved citizen wellbeing, yet this is seldom measured or monetized. Adding such valuation provides a way to more comprehensively reflect the value of associated interventions. Subjective wellbeing measurement is broadly divided between hedonic and eudaimonic streams, benefit monetization focusing on the value of changes in life satisfaction (part of hedonic wellbeing). While improving life satisfaction might have initial value, this might not be sustained if eudaimonic wellbeing is not concurrently promoted, suggesting land use transport policy/planning should take a broader view of what it means for people to be ‘well’ than is embedded in life satisfaction. However, no values have been identified for changes in levels of eudaimonic wellbeing, partly because of lack of agreement about how to best measure eudaimonic wellbeing. To address this monetisation gap, the paper develops a value for changes in eudaimonic wellbeing, measured using Ryff’s (1989) Scale, and explores implications for valuing wellbeing as life satisfaction. The resulting eudaimonic wellbeing values are likely to be particularly useful for evaluating land use/transport initiatives with a local focus, such as walking and place-making improvements, but the monetised values are more broadly applicable. Literature implied that changes in eudaimonic wellbeing may have higher monetized value than changes in life satisfaction, because of the broader societal connections embedded within eudaimonic wellbeing, an expectation confirmed in the analysis, highlighting the policy importance of eudaimonic wellbeing.

Hensher, David A.; Wei, Edward; Greene, William H. Net Zero emission targets have become a politically sensitive policy in many, but not all, countries. It is suggested that they are not achievable and are potentially misaligned with energy security as Net Zero becomes intertwined with the move towards renewables and away from fossil fuel energy sources, where the latter is widely seen as the baseload for many nations. Australia is embroiled in a political debate on whether Net Zero as a target will achieve its emission objectives in the presence of escalating energy prices and uncertainty in respect of cost and damage to an economy, given a wealth of fossil fuel resources, as well as some support for nuclear power which currently is not sanctioned by the Federal government. There has been a lot of media attention to Net Zero (CO2) or greenhouse gas emissions, and it is unclear whether it is well understood, and what it might mean for Australia, given there are views that it is either a great idea or a bad idea. This paper draws on a new survey in Australia to gain an appreciation of public understanding of Net Zero and what the public thinks it might mean for Australians, and how their preferences are aligned with support for political parties. We estimate a hybrid logit choice model of support for political parties that encapsulates the endogeneity of “soft” variables such as latent attitude variables that are driven by observable “causes,” and unobservable heterogeneity, which together with contextual and socioeconomic characteristics provide evidence on preference bias for or against Net Zero associated with political affiliation.

Travis Over the last decade (2015–2025), Mobility-as-a-Service (MaaS) has rapidly evolved from a visionary concept into a mature, user-centric socio-technical ecosystem. This paper marks a ten-year methodological milestone by conducting a PRISMA-guided systematic review of 92 peer-reviewed journal articles from Web of Science, Scopus, and Google Scholar. The existing body of quantitative modeling literature informing MaaS design, operations, and regulation remains fragmented across disciplines, assumptions, and decisionmaking layers. In response, we propose a unified framework that categorizes the literature into six methodological families: simulation models, optimization models, discrete choice models, other statistical methods, data-driven and predictive machine learning models, and game theory and mechanism design models. Using this framework, we map these modeling methods onto four core MaaS research themes: demand-side modeling, supply-side operations, MaaS ecosystem governance, and platform and subscription bundle design. Major findings indicate that existing demand studies have predominantly relied on stated-preference valuations of MaaS subscription plans and bundles, with only limited revealedpreference validation; optimization models have increasingly formalized allocation, matching, and assignment under operational constraints, albeit often assuming overly simplified traveler behavior; and machine learning techniques have expanded rapidly but are generally deployed as stand-alone prediction tools rather than integrated into policy-constrained decision support systems. In addition, the maturity levels of each methodological family reveal significant disparities: foundational areas such as revealed-preference modeling and choice-based optimization are well-established (extensively studied), while emerging fields like machine learning and game theory remain less studied or in early-stage exploration. To advance the field, we provide a forward-looking agenda of 20 research directions, prioritizing more data-driven behavioral modeling, tighter demand–supply integration in operational settings, new multi-sector partnerships, and the concept of Mobility-as-a-Feature. We emphasize planning for equity and long-term impacts and the responsible incorporation of emerging technologies into next-generation MaaS. This systematic methodological review provides evidence-based guidance and a structured roadmap for researchers, operators, and policymakers, addressing identified gaps and highlighting areas requiring further development to support robust, policyaligned decision-making in MaaS.

While we see claimed success in Japan and China, this is the result of a government led and controlled initiative with extensive subsidy, something which appears to be beyond possibility in most countries. Certainly, to date, there are examples of Governments (e.g., across Europe) claiming interest and commitment but no financial support beyond existing subsidy to public transport available to all users. In researching MaaS over the last 10 years, we have come to the position that its future may reside in a greater involvement of non-mobility service providers (NMSPs) in recognition that a multi-service focus may offer up some real prospects of not only delivering desirable travel behaviour change but in facilitating a scalable outcome. Mobility as a Feature (MaaF) is one interpretation of this revised eco-system and has informed us of the potential opportunities that can be invoked through participation of NMSPs. To understand whether this has prospects, a survey in six countries in 2024 was undertaken to identify initiatives that are already in place within private enterprise and government agencies that align well with contributing to sustainable travel behaviour goals. The results suggest that much is already happening, but it has not been recognised as a MaaS/MaaF-like initiative. This paper presents the evidence and suggests a re-interpretation of what a future MaaS portfolio may look like, noting that this scalable future does not have to depend on the transport service providers working together other than their presence in providing services in the market to anyone wishing to use them. The focus historically on transport service providers appears to have been a major roadblock in progressing MaaS.

Established objectives for behaviour change interventions include reducing emissions, alleviating congestion, and enhancing overall well-being through targeted interventions. Drawing on existing frameworks for behaviour change, the paper focuses on the key dimensions which are relevant to the design and evaluation of policy measures. A multi-dimensional conceptual framework of behaviour change interventions in transport is proposed to highlight the importance of combining ‘hard’ measures, such as road user charges and infrastructure investments, with ‘soft’ measures, like public awareness campaigns and incentive programmes. The other three dimensions cover the timeframe for change, the level of change impact and the “push” and “pull” change strategies. Evidence of previous impact is presented, distinguishing between marginal and non-marginal changes and, where appropriate, the longevity of impact. The evidence demonstrates that tailoring these strategies to specific population segments and geographic contexts is crucial for delivering impact, particularly given the diverse travel needs and socio-demographic factors that exist within different jurisdictions. The paper concludes with recommendations for advancing research to better understand the synergetic effects of various behaviour change interventions using the proposed framework.

This paper advances the understanding of sustainable transport policy by highlighting WoC and segmentation as complementary tools for designing and implementing effective interventions. Data is collected from over 4,000 respondents spread across Australia, Finland, New Zealand, the United States, the United Kingdom, Singapore, and Sweden, investigating respondents’ WoC over the period 2023–2025. We also explore the influence of 50 transport-influencing initiatives on how people travel. From a three class Latent Class Analysis model we labelled the classes as “Urban strivers” (characterised noticeably by a majority of members in full-time employment); “Settled simplifiers” (in addition to retirees, including homemakers and other "not working"); and “Dynamic jugglers” (including part-time and flexible workers). Dynamic jugglers are found to be the most receptive of the range of transport-influencing initiatives explored. The comparative analysis of these three classes demonstrates how segmentation, when combined with WoC, can guide policymakers in tailoring transport interventions more effectively.

The most challenging transport reform has always been associated with re-pricing of car use. Despite the growing levels of congestion on our roads, there is general reluctance to support a package of pricing reforms designed to make each and every car user potentially better off financially and/or in saving time. There exist a number of systemwide charging reforms such as the Oregon kilometre-based charging regime, but they are in the main opt-in models, which offer an appealing way for politicians to support the ideals of giving everyone a choice. The cordon-based congestion charging schemes in London, Milan, Stockholm, Gothenburg, New York, and Singapore, while applying to all users who enter a specific location, are limited to one location as is the idea of a congestion-free priced lane. This paper focuses on re-pricing options (with varying charges) to identify how residents are likely to respond to peak period distance-based charging throughout an entire city, cordon-based charges in a defined geographical area, and congestion-free priced lanes on major roads. A series of road pricing initiatives were offered to over 4,000 individuals in seven countries, seeking advice on whether a particular initiative is likely to have a positive or negative impact (or none at all) on how they travel, revealing support or otherwise for a specific re-pricing regime. For each road pricing initiative, we ran a generalised ordered logit model to identify what contextual variables influence the probability of an initiative being associated with a positive impact, a negative impact, or no impact. We are especially interested in understanding how prior “windows of change” associated with lifestyle, mobility, work, commuting, and environmental preferences condition support or otherwise for each road pricing reform initiative. The findings provide suggestions on the extent to which each of the eight initiatives assessed can deliver support or otherwise for road pricing reforms from individuals whose recent past is associated with one or more of the 70 windows of change investigated.

Pellegrini, Andrea; Fielbaum, Andres Shared on-demand mobility can be made more sustainable, but this often involves trade-offs in comfort and cost. For example, electric vehicles emit less CO2 but may require higher fares to compensate for charging time, while walking segments can reduce vehicle-kilometres travelled by avoiding detours, yet offer less comfort than door-to-door services. This study examines travellers’ willingness to choose more sustainable shared mobility options and identifies which users are most likely to make such choices. To do so, we apply an integrated choice and latent variable model to data collected via a discrete choice experiment (DCE) administrated to a sample of residents of the Greater Sydney Area, Australia. Specifically, respondents were presented with three shared mobility options, two of which required walking to reach pickup or dropoff points. Each option was described by a set of attributes, including waiting time, in-vehicle time, emission reduction relative to conventional vehicles, walking time and price. In addition to completing the DCE, respondents answered a series of attitudinal questions designed to capture key travel-related dimensions: safety of car, pro-walk orientation, time sensitivity, and variety-seeking behaviour. Results indicate that respondents who place high value on car safety are less likely to choose carbon neutral trips, whereas pro-walkers are more inclined to select shared mobility services that involve walking to PUDO points. The results are then used to compute willingness to pay values for five distinct user profiles. Our main findings are that (i) Users are generally willing to pay a higher fare to reduce emissions; (ii) Personalized sustainability options yield greater participation and emission reductions than uniform policies; and (iii) Regular public transport users show higher willingness to walk, highlighting potential synergies between on-demand mobility and transit.

To do so, we employ a multivariate multiple discrete-grouped extreme value (MDGEV) model (Bhat et al., 2020) that allows the simultaneous evaluation of where and for how long vehicles are charged across multiple locations, while also capturing potential correlation effects among charging sites. Further, state dependent variables are incorporated into the specification to capture habit persistence effects, whereby past charging choices influence subsequent decisions. The empirical findings indicate that solar panel ownership increases the likelihood of home charging but is associated with shorter charging durations compared with households without photovoltaic access. Residing in major cities is found to be linked to a greater reliance on non-home charging, confirming the prolonged challenges faced by electric vehicle owners in densely populated urban areas. Habit persistence is estimated to play a key role in the charging-decision making process, with EV owners exhibiting routine behaviour when selecting the facility for their next charging activities. The estimated results are next used to investigate how charging duration patterns change under the universal adoption of solar panels and flexible electricity plans, revealing that both policies will impact the rate and duration of charging across locations.
