In attempting to understand and prevent fare evasion, existing research and policy have often categorised fare evaders based on passenger 'types' or profiles. However, such categorisations of 'malicious' or 'virtuous' behaviours rely on underlying moral claims which often go unexamined. In this paper, we study how different actors construct such moral claims as part of everyday interactions. We demonstrate that the everyday moralities of not or under-paying are diverse, locally occasioned, and emotionally charged. Drawing on social media and video data from Chile and the UK, we examine interactions between passengers, by-standers, transport workers, and transport operators. We highlight the diverse resources that actors draw upon to construct moral claims around fare evasion, including the mobilisation of alternative moral categories; attempts to produce exceptions to formal rules; and the foregrounding of moral emotions. The paper engages with an interdisciplinary body of work which reassesses existing policies and societal responses to fare evasion, while also contributing to a nascent literature on everyday morality and mobilities.

This study explores the feasibility of integrating battery technology into electric buses, addressing the imperative to reduce carbon emissions within the transport sector. A comprehensive review and analysis of diverse literature sources establish the present and prospective landscape of battery electric buses within the public transportation domain. Existing battery technology and infrastructure constraints hinder the comprehensive deployment of electric buses across all routes currently served by internal combustion engine counterparts. However, forward-looking insights indicate a promising trajectory with the potential for substantial advancements in battery technology coupled with significant investments in charging infrastructure. Such developments hold promise for electric buses to fulfill a considerable portion of a nation's public transit requirements. Significant findings emphasize that electric buses showcase considerably lower emissions than fossil-fuel-driven counterparts, especially when operated with zero-carbon electricity sources, thereby significantly mitigating the perils of climate change.

Background: A rail passenger delay compensation scheme aiming at improving attractiveness of rail services and providing minimum customer service standards for delayed passengers operates in the European Union and Great Britain. British rail passengers are eligible to claim 50% of fare for delays of more than 30 min and 100% for delays of over 1 h. The scheme rules were chosen arbitrarily and are homogeneous across all ticket types and journey lengths. As longer journeys are usually more expensive and subjected to longer delays, long distance operators are likely to see more passengers being eligible to claim compensation. This, combined with higher engagement rates due to differences in sensitivity to lateness or opportunity cost of not claiming compensation is likely to have an impact on the differing revenue burden for operating companies. Objective: Against this background, this study aims to quantify the revenue impact of homogeneity of scheme rules for different types of train operators to advance understanding of the scheme's costs and motivate further research into the economic rationale behind the scheme's provision and design. Methodology: An econometric model was constructed to empirically test the impact of performance levels and train operator characteristics on the compensation payments made to passengers through the 'Delay Repay' scheme in Great Britain. Results: The combined differences in the nature of operation and engagement levels mean that with delay levels and engagement increasing with journey length and fare, short, medium and long distance train operating companies (TOCs) repay on average respectively 0.3%, 0.8% and 1.8% of their ticket revenues, increasing the scheme's proportionate burden on the revenues of long distance operators. Further research is needed to either explain the economic or regulatory reasons behind the differing revenue impact of the scheme on different types of TOCs or suggest how the scheme can be redesigned to take these differences into account.

Background: The COVID-19 pandemic had a significant impact on the operations and functionality of the public transport sector in the UK. This paper reflects on the experience of this sector through the pandemic period, and considers recommendations for any future mitigations required for either new COVID-19 waves or a different public health emergency. Methods: Semi-structured interviews were carried out with public transport experts, organisational leaders, workers and passengers in two phases: Phase 1 from January to May 2021, and Phase 2 from December 2021 to February 2022. Interviews were analysed thematically. Results: Using the 'What? So What? Now What?' reflective model, ideas are drawn out to describe (a) what changes occurred, (b) what effects these changes had on service provision as well as perceptions of risk and mitigation and (c) what lessons have been learned and how these findings can feed into pandemic preparedness for the future. Respondent reflections focussed on the importance of communication, leadership, and maintaining compliance. Conclusions: The wealth of experience gained through the COVID-19 pandemic in the public transport sector is extremely valuable. Through reflection on this experience, specific recommendations are made relating to these factors, covering: maintaining links across industry, access to information and data, understanding of mitigation effectiveness, improving messaging, challenges of behavioural mitigations, and clear lines of accountability. The recommendations made on the basis of this reflective process will help to improve public health strategy within the public transport sector. [ABSTRACT FROM AUTHOR]

The virucidal activity of the Zoono Z71 Microbe Shield surface sanitizer and protectant, a quaternary ammonium compound (QAC)-based antimicrobial coating that was used by the United Kingdom rail industry during the COVID-19 pandemic, was evaluated, using the bacteriophage ∅6 as a surrogate for SARS-CoV-2. Immediately after application and in the absence of interfering substances, the product effectively reduced (>3 log10) the viability of ∅6 on some materials that are typically used in rail carriages (stainless steel, high-pressure laminate, plastic). If, after the application of the product, these surfaces remained undisturbed, the antimicrobial coating retained its efficacy for at least 28 days. However, efficacy depended on the material being coated. The product provided inconsistent results when applied to glass surfaces and was ineffective (i.e., achieved <3 log10 reduction) when applied to a train arm rest that was made of Terluran 22. Regardless of the material that was coated or the time since application, the presence of organic debris (fetal bovine serum) significantly reduced the viricidal activity of the coating. Wiping the surface with a wetted cloth after the deposition of organic debris was not sufficient to restore efficacy. We conclude that the product is likely to be of limited effectiveness in a busy, multiuser environment, such as public transport. IMPORTANCE This study evaluated the performance of a commercially available antimicrobial coating that was used by the transport industry in the United Kingdom during the COVID-19 pandemic. While the product was effective against ∅6, the efficacy of the coating depended upon the material to which it was applied. Similarly, and regardless of the surface material, the presence of organic debris severely impaired viricidal activity, and efficacy could not be recovered through wiping (cleaning) the surface. This highlights the importance of including relevant materials and conditions when evaluating antimicrobial coatings in the laboratory. Further efforts are required to identify suitable infection prevention and control practices for the transport industry. [ABSTRACT FROM AUTHOR]

Experiments were conducted in an UK inter‐city train carriage with the aim of evaluating the risk of infection to the SARS‐CoV‐2 virus via airborne transmission. The experiments included in‐service CO2 measurements and the measurement of salt aerosol concentrations released within the carriage. Computational fluid dynamics simulations of the carriage airflow were also used to visualise the airflow patterns, and the efficacy of the HVAC filter material was tested in a laboratory. Assuming an infectious person is present, the risk of infection for a 1‐h train journey was estimated to be 6 times lower than for a full day in a well‐ventilated office, or 10–12 times lower than a full day in a poorly ventilated office. While the absolute risk for a typical journey is likely low, in the case where a particularly infectious individual is on‐board, there is the potential for a number of secondary infections to occur during a 1‐h journey. Every effort should therefore be made to minimize the risk of airborne infection within these carriages. Recommendations are also given for the use of CO2 sensors for the evaluation of the risk of airborne transmission on train carriages. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to explore the voice of the customer (VOC) of public transport (PT) users and non-users and to identify the role VOC plays in PT service quality analysis and improvement practices. Design/methodology/approach: This research is based on quantitative and qualitative data collection. Quantitative data were collected through two questionnaires; the first is based on ranking data: 192 responses and the second on the Kano model: 46 responses. The qualitative data was obtained through 10 semi-structured interviews with senior management from seven bus companies in the UK. Findings: Findings indicate that VOC differs between PT users and non-users and compared with the perspectives of PT Providers. The research also revealed that VOC plays a crucial role in PT service quality improvement (QI). Practical implications: The findings can be used by PT service providers to better understand the VOC of PT users and non-users, which will assist in strategic and QI decision-making. Furthermore, an in-depth study of VOC in PT is provided, which progresses the academic field on this topic and advances research in this area. Originality/value: This research brings new insight into the most important quality attributes for PT users and non-users. Moreover, the paper fundamentally contributes to the literature, which until now had severely limited input pertaining to the role of VOC in PT and little knowledge of service QI tools and practices in this sector.

In a drive to achieve net zero emissions, U.K. transport decarbonisation policies are predominantly focussed on measures to promote the uptake and use of electric vehicles (EVs). This is reflected in the COP26 Transport Declaration signed by 38 national governments, alongside city region governments, vehicle manufacturers and investors. However, emerging evidence suggests that EVs present multiple challenges for air quality, mobility and health, including risks from non-exhaust emissions (NEEs) and increasing reliance on vehicles for short trips. Understanding the interconnected links between electric mobility, human health and the environment, including synergies and trade-offs, requires a whole systems approach to transport policymaking. In the present paper, we describe the use of Participatory Systems Mapping (PSM) in which a diverse group of stakeholders collaboratively constructed a causal model of the U.K. surface transport system through a series of interactive online workshops. We present the map and its analysis, with our findings illustrating how unintended consequences of EV-focussed transport policies may have an impact on air quality, human health and important social functions of the transport system. We conclude by considering how online participatory causal modelling techniques could be effectively integrated with empirical metrics to facilitate effective policy design and appraisal in the transport sector.

The combined decentralisation of many firms and services and the increasing concentration of traditional public transport services in the main corridors of urban centres have made it more difficult for people to access jobs, in particular when residing outside these prime accessibility areas. This is the first national study within the context of Great Britain to examine whether better public transport job accessibility, modelled at the micro level of individuals, improves employment probabilities for people living in Great Britain. While previous studies have typically concentrated on US metropolitan areas, our study uses British national employment micro datasets to assess which urban and rural areas and population groups would benefit from better public transport services. In an important departure from most standard accessibility methodologies, we computed a public transport job accessibility measure applied nationwide and combined this with individual-level employment probability models for Great Britain. The models were corrected for endogeneity by applying an instrumental variable approach. The study finds that better public transport job accessibility improves individual employment probabilities, in particular in metropolitan areas and smaller cities and towns with lower car ownership rates and in low-income neighbourhoods. It further shows that mainly lower educated groups and young people would benefit from better public transport job accessibility. The findings in this study are important for policymakers in that they imply that, in particular, job seekers who rely on public transport services may benefit from more targeted public policies to improve their accessibility to employment and thereby their social mobility.

Few contemporary studies of change in industrial relations use Carter Goodrich's classic concept of the 'frontier of control' (FoC), especially in cross-national comparative research. Our study maps FoC struggles in two public transport organizations in the UK and the Republic of Ireland. Qualitative methods generate significant insights into complex day-to-day workplace control patterns in these two cases. Despite changes in the frontier of control in both organizations over time, it is observed that employment relations in the Irish case are more cooperative than in the British. The frontier of control still matters, because workplace control regimes shape managerial ability to secure worker consent and are always potentially contestable terrains. [ABSTRACT FROM AUTHOR]

Covid-19 has had a major impact on public transport systems across the world. Public financial support has been needed to maintain services in the face of drastically reduced ridership and adjustment to the need for social distancing. This paper explores the challenge this poses to current methods of delivery of public transport services and argues that a simple return to the status quo is unlikely as public transport adjusts to a new normal of more home working and fear of crowded spaces. In turn this impacts most on the transport disadvantaged. The paper argues that this may spell the end of the prevailing model of a deregulated competitive public transport that has prevailed in the United Kingdom and require a major rethinking of the way to provide an efficient and effective transport system. Such a rethink will depend on understanding the interplay of private and social norms and building public trust. • Transport impacts of Covid-19. • Public transport. • Government funding. • Transport planning. • United Kingdom.

A recent explosion of research on the travel behaviour of the millennial generation has found that compared to past generations they are taking longer to get a driving license, driving less, owning fewer cars and using transit more. Yet these findings are not universal with some countries seeing increases in driver licensing, little change in driving or reductions in public transport use. Most past research has explored wider social and economic explanations for these trends, such as income constraints and delays in adult life transitions. Very few studies have examined the role that local context plays in explaining the change (or the lack of change) in millennial travel behaviour. This paper aims to compare how trends in young adult travel behaviour differ across diverse city contexts. It uses a comparative descriptive analysis of household travel surveys from cities in three countries (UK, USA and Australia), focussing on auto-miles and transit-miles travelled. We find that each city experienced markedly different trends in young adult travel behaviour that are unlikely to be explained by economic differences alone. We suggest that changes to the transport systems in these cities are likely to be playing an under-recognised role in shaping travel behaviour. We suggest that further research should pay greater attention to the role of the transport system in supporting changes to travel behaviour among the next generation of young adults. • Explores travel behaviour of millennials in 6 areas of the UK, USA and Australia • Macroeconomic trends impact car use among millennials. • Some evidence life stage is impacting travel of millennials. • City investments in transit likely play an important role in these trends.

In recent years, concerns over effective consumer representation of public transport users have increased considerably, as public transport has undergone substantial regulatory reforms. The ultimate goal of deregulation is to protect and benefit the public at large. Hence, this paper explores how this goal is being pursued by examining the roles of statutory, independent passenger watchdogs and their relationships with authorities and operators in regulated and deregulated bus regimes. Drawing on a case study of London TravelWatch and Transport Focus in Great Britain, our findings show that statutory passenger watchdogs are effective in representing passenger interests due to four factors in particular: the organizational setting, research-based evidence, accommodating relationships, and public outreach. The paper also documents the differences in how these passenger watchdogs build their relationships with key stakeholders and work with them within the strategic-tactical-operational framework.

Harnessing a unique data source – longitudinal travel smartcard data linked to passenger demographics from 2019 to 2022 – we use methods of survival analysis to model the recovery of public transport patronage among 183,891 senior citizens resident in the West Midlands metropolitan region in the United Kingdom. Comparing pre and peri-pandemic patronage, we identify pronounced social and spatial inequalities in the speed of return to public transport. We find that male, younger and non-White passengers are more likely to return to public transport as soon as movement restrictions were lifted, whereas passengers from White ethnic background and affluent areas do not return to public transport within the first year after the outbreak. Pronounced social inequalities persist into the middle of 2021, and only thence they began to attenuate as part of a wider return to public transport among passengers post retirement age. In 2022, 80% of these passengers have returned to public transport but the frequency of use has remained lower than prior to the pandemic. We discuss implications for transport policy and planning. • We analyse smartcard records of 184 k senior citizens with linked age, gender and ethnicity. • We study patterns in public transport demand since the COVID-19 pandemic to the present. • We find unequal speed of return to public transport by socio-demographics and geography. • We identify a specifically ethnic dimension in unequal return to public transport. • Inequalities and social gradients in public transport demand reduce but persist.

In Britain, many disabled people have access to a car through the Motability Scheme. However, with recent news of thousands of disability claimants losing their cars in cuts, it is worth reflecting on the cultural and symbolic importance of the motor car. This article considers the car’s ability to expand spatial and experiential horizons and offer a site of sanctuary for disabled people, and asks what can be lost in the wake of the recent government reassessment of the scheme.

Background: Changes to the environment that support active travel have the potential to increase population physical activity. The Cambridgeshire Guided Busway is an example of such an intervention that provides new traffic-free infrastructure for walking, cycling and public transport. This qualitative investigation explored the diverse experiences of new transport infrastructure and its impacts on active travel behaviours. Methods: Thirty-eight adult participants from the Commuting and Health in Cambridge natural experimental study were purposively selected according to their demographic and travel behaviour change characteristics and invited to participate in semi-structured interviews between February and June 2013. A mixed-method, following-a-thread approach was used to construct two contrasting vignettes (stories) to which the participants were asked to respond as part of the interviews. Inductive thematic qualitative analysis of the interview data was performed with the aid of QSR NVivo8. Results: Perceptions of the busway's attributes were important in shaping responses to it. Some participants rarely considered the new transport infrastructure or described it as unappealing because of its inaccessibility or inconvenient routing. Others located more conveniently for access points experienced the new infrastructure as an attractive travel option. Likewise, the guided buses and adjacent path presented ambiguous spaces which were received in different ways, depending on travel preferences. While new features such as on board internet access or off-road cycling were appreciated, shortcomings such as overcrowded buses or a lack of path lighting were barriers to use. The process of adapting to the environmental change was discussed in terms of planning and trialling new behaviours. The establishment of the busway in commuting patterns appeared to be influenced by whether the anticipated benefits of change were realised. Conclusions: This study examined the diverse responses to an environmental intervention that may help to explain small or conflicting aggregate effects in quantitative outcome evaluation studies. Place and space features, including accessibility, convenience, pleasantness and safety relative to the alternative options were important for the acceptance of the busway. Our findings show how environmental change supporting active travel and public transport can encourage behaviour change for some people in certain circumstances. [ABSTRACT FROM AUTHOR]

Abstract: Using photographs, this paper explores the gendered link between transport and the urban environment. It becomes apparent that moving around in urban spaces is an experience which is or can be fundamentally different for women and men. From pictures I conclude that a historical analysis of gender and urban transport ought to be a straightforward task to undertake: women are clearly visible in the visual record of the transport environment. However, a look at the historiography shows that research on gendering the city mostly deals with workplaces, women’s employment, class and race segregation in urban areas, welfare programmes specially designed to helped women, urban housing and marginalisation of women, housewives, healthcare, homeless women and politics. Gender and transport is hardly to be found: how women move and moved through urban space has not received sustained attention. Further, the main body of scholarly texts lacks in historical concern, stemming from such diverse disciplines as sociology, geography, economic and political sciences, women’s studies and planning. In this paper, I examine the interrelation between transport, gender and space to explain eventual gender inequalities we are confronted with at the end of the twentieth century, firstly to shed light on the experience of women travelling on public transport; secondly to examine moving around in cities in a wider sense by focussing on walking; and thirdly to seek to explain the change of urban structures that determine transport by analysing traffic planning. Eventually these three aspects of gendered transport in cities reveal what different spaces and places women used, experienced and how such a specific experience promoted the construction of gendered social and economic identities.

Abstract: This paper reviews public transport crowding valuation research, using a number of primary studies conducted in the UK, USA, Australia and Israel. We identify three measures used to value crowding (a time multiplier, a monetary value per time unit and a monetary value per trip), and associated ways of representing crowding in stated preference experiments. Although a number of different types of crowding in terms of location are identified, namely in-vehicle, access-way, entrance and platform/station, the majority of reviewed studies investigate only in-vehicle crowding. Despite the different characteristics of the reviewed studies, they all report that crowding would increase the value of travel time savings, which can be viewed as an additional component of generalised time. This paper also comments on the role that the WTP for crowding reduction can play in project appraisal, and suggests some important avenues for future public transport crowding valuation research.

Abstract: Domestic express coach services in Germany have long been heavily restricted by regulation, although offerings comparable to countries like, for example, Great Britain or Sweden bear substantial opportunities for competition, the environment, and mobility. In this paper, we motivate market entry in the German express coach market for local public and integrated transport companies by high profitability rates in other countries and the availability of bus facilities and skills. This is followed by the evaluation of supply and demand. Supply is represented by an analysis of external and internal costs showing that express coaches have significant cost advantages that are intensified by the possible internalization of external costs. Demand is represented by a survey of customers that is evaluated with a conjoint analysis. Our results suggest a market share for express coach services in Germany of at least 5.3%.

Abstract: The 1998 White Paper proposed integration as the solution to Great Britain’s land transport problems. Most commentators agree that this much vaunted New Deal for Transport has been a failure. Yet some ten years later policy papers from bodies such as the Institution of Civil Engineers and the Centre for Cities are still proposing integration as a possible panacea. There are a number of reasons for the failure of integrated transport over the last decade. The first is the failure to define the concept. The second is the failure to operationalise the concept. The third is the lack of an evidence base on the success of integrated transport policies. Evidence is now emerging in Britain on the benefits (and indeed the costs) of some aspects of integrated transport policies. The fourth, and perhaps the most crucial, is the lack of will in terms of politicians, civil servants and the public at large, to adopt the behavioural changes necessary for an integrated transport policy to be successful. A series of organisational and funding changes are proposed that could advance the prospects for integration. [Copyright &y& Elsevier]

Abstract: In January 2009, following a lengthy industry review and consultation process, the New Zealand Public Transport Management Act (PTMA) came into force. The Act allows Regional Transport Authorities, as the primary procurers of public transport services, to place either a control or a contracting requirement upon services that are registered as commercial requiring no subsidy. The imposition of either the control or the contracting requirement is designed to facilitate greater system integration, improve service continuity and enhance services to the customer, andallow the Authority to invest in key strategic projects, such as integrated fares and ticketing, so as to grow patronage. The PTMA’s other objective is to ensure improved value for public subsidies. Recent years have seen significant subsidy inflation for seemingly little commensurate benefits. The Act will allow the Regional Transport Authority to achieve greater value for money through improved farebox, a shift to longer, larger contracts to increase competition in the market, a more appropriate allocation of risk, and the removal of the ability of operators to ‘game’ the current system by using strategically placed commercial services as barriers to competition. Similar concerns have also stimulated new legislation in the UK and this paper illustrates the parallels in the environment and proposed response. [Copyright &y& Elsevier]

Abstract: In the context of growing policy awareness in the UK of the links between transport and social exclusion, this paper describes case-study research of four different transport projects funded under the UK Department for Transport''s Urban Bus Challenge Fund (UBC) with the specific aim of facilitating social inclusion in the areas they serve. Through surveys and interviews with end-users, the study qualitatively and quantitatively evaluated the value of these new services to local residents in terms of their increased economic opportunities and other quality of life benefits. It also aimed to identify their wider contribution to the renewal and regeneration of the deprived areas they serve through depth interviews with professional local stakeholders.

Enhancing the bus experience through improved information provision is a key element of UK Government transport policy. Real time passenger information (RTPI) is perceived to reassure waiting passengers, to benefit the bus operator through increased revenue and the local authority, by promoting social inclusion and achieving a modal shift. RTPI also provides an important tool for operators by allowing them to monitor services and refine their schedules. The aim of this paper is to understand the reasons for implementing RTPI in the bus sector, and to determine the key issues impacting on the likely success of such a policy. A case study approach investigates the experiences of two provincial towns in the UK. The paper suggests that, whilst it is unclear whether RTPI has resulted in an increase in bus patronage, it is considered to be most effective when combined as part of a package of measures. It is intended that the findings from the two case studies will reveal lessons of relevance to authorities contemplating the introduction of RTPI. [ABSTRACT FROM AUTHOR]

Two major passenger transport executives and the Countryside Agency launched the Wayfarer project in the UK in 1980. The principal aim was to investigate ways of encouraging visitor access to the countryside by public transport. One initiative stemming from the project was the introduction of a multi-modal ticket in 1983, known as Wayfarer, to encourage a day excursion market from urban centres to the countryside, and in particular to one of the busiest natural parks in the world, the Peak District National Park. Over 20 years later the Wayfarer ticket is still being marketed to encourage sustainable travel for leisure. This paper's purpose is to profile Wayfarer users, to explain key reasons for ticket choice, and give insights into the use of public transport for recreational travel. The study also attempts to evaluate the extent to which modal shift can be encouraged. The results indicate that this type of multi-modal passenger transport ticket, marketed for recreational and tourism purposes, has the potential to offer a more sustainable modal choice to residents and visitors.

This paper reports research on the valuations of public transport time relative to car travel time and on the valuations of the walk time, wait time and service headway associated with public transport use. The results are derived from a meta-analysis of a very large data set of British empirical evidence and are set against a review of previous research. A large number of methodological and policy relevant results emerge, some of which challenge established conventions, and the implications for value of time recommendations, policy and further research are spelt out.

The aim of current transport policy in the UK and many other developed countries is to reduce reliance on private motor vehicle transport in order to promote public health and reduce environmental degradation. Despite the emphasis in these policies on the unhealthiness of private motor car use, epidemiological studies have consistently shown that car access is associated with longevity and better health. We examine this paradox using a postal survey of adults in the West of Scotland (n=2043, m=896, f=1147) to investigate the psychosocial benefits associated with private and public motor vehicle transport. Those with access to a car appear to gain more psychosocial benefits (mastery, self esteem, and feelings of autonomy, protection, and prestige) than public transport users from their habitual mode of transport. Being a car driver conferred more benefits than being a passenger, except for self esteem which was only associated with driving among men. Self-esteem was also associated with type of car among men but not women. This study suggests that if people are to be encouraged to reduce private motor vehicle use, policies need to take into account some of the psychosocial benefits people might derive from such use.

A series of experiments was undertaken on an intercity train carriage aimed at providing a "proof of concept" for three methods in improving our understanding of airflow behaviour and the accompanied dispersion of exhaled droplets. The methods used included the following: measuring CO2 concentrations as a proxy for exhaled breath, measuring the concentrations of different size fractions of aerosol particles released from a nebuliser, and visualising the flow patterns at cross-sections of the carriage by using a fog machine and lasers. Each experiment succeeded in providing practical insights into the risk of airborne transmission. For example, it was shown that the carriage is not well mixed over its length, however, it is likely to be well mixed along its height and width. A discussion of the suitability of the fresh air supply rates on UK train carriages is also provided, drawing on the CO2 concentrations measured during these experiments. [ABSTRACT FROM AUTHOR]

• Improvements to train technology cannot solely be relied upon to reduce emissions. • Decarbonisation of the electricity generation mix is needed to reduce emissions. • Electric trains produce lower levels of cumulative emissions than hydrogen trains. • Conventional train emissions were 2.6 times lower than conventionally fuelled cars. • By 2050 conventional trains produce 5–14 times more emissions of new technology. Electric trains (ET) and hydrogen trains (HT) are considered zero emission at the point of use. True emissions are dependent upon non-tailpipe sources, primarily in energy production. We present UK carbon dioxide (CO 2) operating emission model outputs for conventionally fuelled trains (CFT), ETs and HTs between 2017 and 2050 under four National Grid electricity generation scenarios. Comparing four service categories (urban, regional, intercity and high speed) to private conventionally fuelled vehicles (CFV) and electric vehicles considering average distance travelled per trip under different passenger capacity levels (125%, 100%, 75%, 50% and 25%). Results indicate by 2050 at 100% capacity CFTs produce a fifth of the emissions of CFVs per kilometre per person. Under two degree generation scenario, by 2050 ETs produced 14 times and HTs produced five times less emissions than CFTs. Policymakers should encourage shifts away from private vehicles to public transport powered by low carbon electricity. [ABSTRACT FROM AUTHOR]

Rationale: Residents of neighbourhoods with high destination accessibility (higher population density, more-interconnected streets, and better access to services, public transport and parks) are more physically active. Evidence on the factors that underlie these associations is sparse and inconsistent., Objective: We examined (1) five socio-demographic and four non-destination perceived neighbourhood attributes as moderators of the relationship between objectively-assessed destination accessibility and moderate-to-vigorous physical activity (MVPA); (2) perceived indicators of destination accessibility as mediators of those relationships; and, (3) the generalizability of findings across 14 cities., Methods: Data were from the International Physical Activity and Environment Network (IPEN) Adult study (N = 6822), which provided comparable objective and perceived environmental variables and accelerometer-based MVPA from 14 cities across 10 countries. Mediation and mediation moderation analyses were performed., Results: Objective net residential density, public transport density, and number of parks in the neighbourhood were consistently associated with MVPA across all examined socio-demographic groups and non-destination perceived neighbourhood characteristics. However, only the association between number of parks and MVPA was mediated by its conceptually-comparable perceived indicator. While the associations of objective intersection density and land use mix with MVPA were moderated by both gender and perceived pedestrian infrastructure/safety, only the latter moderating effects were mediated by the conceptually-comparable perceived indicators. Perceived neighbourhood safety and/or aesthetics moderated the associations of objective ratio of retail/civic land to total area and distance to nearest transport stop with MVPA. These associations were not mediated by the conceptually-comparable perceived indicators., Conclusion: Densely populated neighbourhoods with access to public transport and parks have the potential to significantly and equitably contribute to adults' MVPA on a global scale. Perceived neighbourhood aesthetics, pedestrian-friendliness and safety can magnify the positive effects of mixed-use neighbourhoods on residents' MVPA by interacting with the perceived ease of access to a variety of destinations., (Copyright © 2018 The Authors.
