This study examines the factors influencing the travel behaviour of Delhi's working population, utilizing retrospective cross-sectional data from 2005 to 2019 collected across four neighbourhoods. The research provides empirical evidence on how travel mode choices have evolved over time in response to changes in the built environment and socioeconomic conditions. GIS-based analysis was conducted to assess the impact of temporal variations in the built environment on travel behaviour. Results reveal a 21% increase in the reliance on private modes of transportation between 2005 and 2019, with the most significant rise observed in 4-wheeler usage. Conversely, bus usage declined by 32%, attributed to various factors including overcrowding, hygiene concerns, and perceived reliability issues. However, in 2019, Connaught Place reported the highest bus usage at 28%, attributed to its high bus stop density, while enhanced metro facilities across the neighbourhoods led to a 20% increase in overall metro ridership. Multinomial logistic regression analysis identified key socioeconomic determinants of travel behaviour, including age, gender, income, vehicle ownership, and commuter attitude. In 2005, two-wheeler preference over buses was primarily driven by vehicle ownership (O.R.: 620.95), gender (O.R.: 4.20), and income (O.R.: 1.28). By 2019, commuter attitude (ProPV) emerged as a significant factor, alongside vehicle ownership (O.R.: 136.72), ProPV (O.R.: 21.41), and income (O.R.: 2.14). A similar trend was observed for car usage, highlighting the increasing influence of commuter behaviour and attitudes on travel choices over time. These findings underscore critical policy implications for the development and enhancement of Delhi's transport system, offering insights that could be applicable to other cities facing similar challenges. [Display omitted] Key Highlights. ⁃ Travel behaviour is complex, differing by region and evolving over time. ⁃Habitual behaviour shapes work travel mode choices in Delhi. ⁃Mixed land use and good transit access boost public transport use. ⁃Safety and comfort are key in car choice for Delhi's workers. ⁃Built environment, socioeconomics, and behaviour influence Delhi's travel modes. ⁃Delhi's transport planning needs balanced infrastructure and behaviour strategies.

Public opinion has been identified as one of the main drivers of political action in support of sustainable-transport transitions, making it essential to understand when aiming for effective transport policy. Drawing from both quantitative and qualitative data from the 2021 Montréal Mobility Survey, this paper analyzes public perceptions towards two transport projects—a light-rail transit (LRT) and a bus-rapid transit (BRT). Quantitative statements pertaining to five project impacts were compared between the two projects. Both projects had high levels of agreement (between 67% and 80%) regarding expected regional and environmental impacts, but agreement levels were lower for expected neighborhood, cultural, and residential displacement impacts (between 49% and 30%). To contextualize the quantitative findings, qualitative data were pulled from open-ended questions for both projects and analyzed using an applied-thematic-analysis approach. The qualitative responses focused primarily on negative perceptions, providing insight into potential factors contributing to the erosion of social acceptability. Our analysis of open-ended questions underscored contrasting perceptions between the two projects in terms of improvements in accessibility to destinations (minimal for the BRT vs noticeable for the LRT), governance (transparent for the BRT vs opaque for the LRT), consultation processes (adequate for the BRT vs insufficient for the LRT), and construction impacts (lengthy and disruptive for the BRT vs rapid for the LRT). These contrasting quantitative and qualitative results highlight the need for mixed methods when assessing public perceptions. Findings from this paper can be of benefit to practitioners and policy makers as they aim to ramp up efforts to expand public-transit systems. • Adequate public consultation can contribute to positive public perceptions. • Suburbanites' opposition to change may hinder LRT effectiveness. • Perceived equity of public transit projects can influence social adhesion. • Better communication is warranted on benefits and impacts of transport projects.

• Intention to use ST at T1 is the best predictor of STC at T2. • Time is the major barrier to using a sustainable alternative. • What predicts intention? Perceived behavioral control is the stronger predictor. • Responsibility's Ascription and Consequences'awareness affect STC via Moral Norm. • Social Norms affect STC through Perceived Behavioral Control. According to the European Environment Agency (European Environmental Agency, EEA, 2018), road transport is responsible for 72% of all transport-related greenhouse gas emissions in the European Union (EU), which accounts for 25% of total energy-related emissions (Eurostat, 2018). Thus, it is crucial to identify drivers and barriers to more sustainable transport behaviors. In this regard, the Norm Activation Model and Theory of Planned Behavior have often been used as conceptual frameworks for predicting such behaviors. The present study aimed to analyze the differential impact of both socio-psychological factors and persuasive messages sent through a Personalized Travel Plan (PTP) on Sustainable Transport Choices (STC). To reach this aim we administered a survey two times (T1: Oct./Dec. 2020; T2: March/May 2021) to 398 car users. Measures of constructs included in the Norm Activation Model and the Theory of Planned Behavior, such as behavioral intention, attitude, perceived behavioral control, beliefs, and personal and social norms, were detected. Participants were then exposed to a PTP built on feedback information regarding kilocalories, CO 2 emissions, cost, and time savings when using sustainable transport compared to driving a car. Structural Equation Modeling (SEM) analysis shows that intention to use sustainable transport in T1 is on one side directly predicted by personal norm, perceived behavioral control, and attitude, and on the other side emerged as the main predictor of sustainable travel choices in T2, together with kcal spent, whereas time was the major barrier. Implications and future developments are discussed in the light of the conceptual framework. [ABSTRACT FROM AUTHOR]

Healthcare contributes significantly to carbon dioxide emissions, which can be reduced by promoting sustainable mobility amongst staff commuting. This study aims to investigate the national sustainable transport infrastructure for staff of healthcare facilities and utilise this data to develop a novel scoring and ranking system. This was an empirical retrospective observational study. Data was collected on all 47 hospitals sustainable transport infrastructure. A working group calculated the weighted scores for each sustainable transport data point. These scores were used to calculate the Total and Active Sustainability Scores for each hospital, allowing a ranking to be formed. 7 of 47 (15 %) hospitals had EV charging on campus. 17 of 47 (36 %) hospitals had secure bike parking. 2 of 47 (4 %) hospitals had a "bike hub". 18 of 47 (38 %) hospitals had a bike lane. 13 of 22 (59 %) city hospitals had bike sharing facilities. 42 of 47 (89 %) hospitals had one public transport route. City hospitals ranked higher in both Total & Active Sustainability Scores. This study explored a new concept of measuring sustainable transport infrastructure. Frameworks examining sustainability are available, however, none allowed for ranking of hospitals. This study highlights the lack of both research in this field and sustainable transport infrastructure in hospitals. • Development of a novel sustainable transport infrastructure scoring system. • Paucity of sustainable transport infrastructure in hospitals for staff nationally. • Actively commuting to work is beneficial to climate change and public health.

In this article, we analyse India's transport sector policy. The study examines the two important modes of transport, viz., road and rail, and analyses the efficiency of transport infrastructure from 2011 to 2019. Through Data Envelopment Analysis (DEA), we evaluate modes in terms of the capacity of registered road goods vehicles and railway goods wagons, truck km/train km and energy consumption and corresponding freight traffic. The analysis gives valuable insight into the fact that rail infrastructure is more efficient than road infrastructure. Still, current transport sector policies promote energy-intensive carbon-fuel road vehicles rather than energy-efficient alternative transport modes. The study suggests the changes that may be incorporated in inputs to improve the efficiency of the road infrastructure. The Data Envelopment Analysis (DEA)-Malmquist Index analysis reports the need for total factor productivity improvement in rail transport and the introduction of technological innovations in road and rail transport sector management. The study employs a well-to-wheel (WTW) based index to ascertain the energy consumed and pollutants emitted by freight-carrying road and rail modes between two leading business hubs of India, i.e., Ludhiana and Mumbai. The paper identifies policy gaps and suggests a holistic approach for need-based roadway investment and a time-bound development of railway infrastructure in India. Our study generates valuable implications for India's policy planners and government authorities and provides new insights to other countries. • The study examines road and rail transport, and analyses the efficiency and energy consumption of these modes. • The study suggests the changes to improve the efficiency of the road infrastructure. • The Data Envelopment Analysis (DEA)-Malmquist Index analysis and well-to-wheel (WTW) based index have been employed for the analysis. • The paper suggests a need-based roadway investment approach and a time-bound development of railway infrastructure.

Transitioning to electric motorcycles (EMs) can reduce dependence on carbon-based fuels, mitigate air pollution, and lower greenhouse gas emissions in countries where motorcycles dominate the transportation landscape. However, the factors influencing fleet electrification in these countries remain largely unknown. Given that this challenge pertains to the prior adoption of new technology, technology acceptance theories can provide valuable insights into the adoption of EMs. Additionally, misinformation about EM risks and self-assessment of knowledge could interact as determinants of adoption. This study integrates the Technology Acceptance Model (TAM), the Theory of Planned Behavior (TPB), and perceived risk to elucidate the impact of psychosocial factors on consumers' intentions to use EMs. Furthermore, it examines the direct and moderating effect of subjective knowledge about EM technology on the formation of this behavioral intention. Structural Equation Modeling (SEM) analysis was applied to investigate data collected from 762 respondents through personal interviews using a questionnaire. The results confirm that all original TAM and TPB constructs significantly influence behavioral intention, aligning with theoretical expectations. As hypothesized, perceived risk was found to exert a negative influence on the intention to adopt EMs. Additionally, subjective knowledge was observed to moderate the relationship between perceived usefulness and subjective norms concerning the intention to use EMs. These findings offer a roadmap for developing strategies aimed at encouraging adoption intentions toward EMs, particularly in countries like Vietnam. • Misinformation about EM risks and self-assessment of knowledge could interact as determinants of adoption. • The model was developed by intergrating TAM, TPB and perceived risk. • Structural Equation Modeling (SEM) analysis was applied to investigate data collected from 762 respondents. • Perceived risk was found to exert a negative influence on the intention to adopt EMs. • Subjective knowledge was observed to moderate the relationship between perceived usefulness and subjective norms.

• Working from home (WFH) is permanent and could encourage significant trip avoidance. • Despite greater WFH, private motor vehicles could become more dominant post-pandemic. • The expected long recovery of public transport use is a concern. • Significant increases in bicycling and walking are anticipated to continue. An unexpected outcome of the COVID-19 pandemic were the dramatic travel behaviour changes experienced in cities worldwide, which, could result in more sustainable transport systems. Consequently, there is a need for longer-term post-pandemic travel behaviour change research. This study aimed to investigate city-level travel behaviour changes during and post-pandemic. To our knowledge, this is the first qualitative study exploring the permanency of COVID-19 travel behaviour changes. This study involved a literature review of 41 studies and in-depth interviews with 19 transport stakeholders in metropolitan Melbourne, Australia. Melbourne is a valuable study area, given that it was the most locked-down city globally. Overall, the results of this study suggest that post-pandemic travel behaviour will be different to pre-pandemic, with working from home (WFH) an integral influence on travel behaviour. In addition, several overarching travel behaviour changes were identified: WFH significantly increased during the pandemic and is anticipated to continue post-pandemic. Both public transport and private motor vehicle (PMV) trips decreased during lockdowns; while PMV rebounded quickly, public transport remained low, and a long recovery is expected. Active transport (cycling and walking) increased during the pandemic and appear likely to endure. Finally, while shared travel modes have received less attention, modal variance is expected in the future. This study has made several key contributions. It consolidated our understanding of the wide range of urban travel behaviour changes experienced during and anticipated post-COVID-19. Secondly, it synthesised current knowledge of recent post-COVID-19 travel behaviour change research. Thirdly, this study demonstrated that complementary qualitative studies strengthen transport research by unearthing new insight into the reasons underpinning travel behaviours, which could be vital for developing solutions. Furthermore, this study identified critical future research topics. Given that most countries are learning to live with the virus, it is an opportune time to investigate whether these intended travel behaviours have endured. [ABSTRACT FROM AUTHOR]

The manuscript presents the management of waste from marine vessels and cargo handling companies in a selected European Union port. The main objective of the paper is to analyse and evaluate the existing waste management model in the port of Szczecin in the context of circular economy. The expert research carried out is aimed, inter alia , at identifying which of the solutions currently in use need to be improved from an environmental perspective. These measures could serve as a basis for the development of green logistics chains for waste generated in connection with the organisation of shipping. What is of particular importance in this regard is the information flow, which preferably should be an integral part of an international IT system enabling tracking of waste streams from their place origin to final disposal. In light of the above, it is particularly important to look for solutions which will support the creation and adoption of models providing sufficient control over the entirety of green waste management activities, in line with the circular economy concept.

Transportation is a major contributor to anthropogenic climate change driven primarily by private automobility and for nearly a century, cities have used a suite of policies and regulations that reinforce high rates of car ownership. One such regulation is minimum parking requirements, enacted to ensure that private properties can accommodate the storage of private vehicles. In recent years, cities have begun to reevaluate these parking requirements, with some municipalities reducing them, others providing opportunities for flexible parking, and some even removing parking requirements in part or all of the city. This article explores the relationship between parking requirements and car ownership by analyzing a survey of 56 municipalities across Sweden. In this paper, we develop two methods for comparing different parking metrics that municipalities use (parking spaces per apartment and parking spaces per building area). Our analysis examines variation between different sizes and classifications of municipalities. We find that across all municipalities, there is a positive relationship between minimum parking requirements and car ownership, meaning that higher minimum parking requirements are associated with higher rates of car ownership. City size is an important factor in rates of car ownership, but our analysis shows that even among similarly sized municipalities, minimum parking requirements tend to be associated with higher rates of car ownership. These findings show that reducing parking minimums can be an effective policy to reduce car ownership, but it is important to consider that these changes only impact new development and repurposing parking areas in existing housing areas may be an equally effective policy to curb car ownership. • Research on the relationship between minimum parking requirements and car ownership. • Analyze a survey of parking requirements and car ownership in 56 municipalities in Sweden. • Develop and compare two different methods for comparing parking numbers used by municipalities. • Results show a positive relationship between minimum parking requirements and car ownership within similarly categorized municipalities.

Transformative changes are needed in the transport sector to limit global warming. Radical transport disruptions experienced during the COVID-19 pandemic, such as greater Working from Home (WFH) and active travel, present a unique opportunity to reimagine more sustainable transport systems. The aim of the current study was to develop a 2050 transport vision and identify short term priorities for Melbourne (Australia) based on in-depth stakeholder interviews. To the best of our knowledge, this is the first backcasting study since COVID-19. As the city with the 'longest lockdown', Melbourne has valuable lessons for the rest of the world. Overall, participants reported that they were uncertain about the future of the central business district. Participants envisaged that the transport system would be carbon-neutral or carbon-positive. However, private motor vehicles (including electric and automated) were not considered the solution for handling the scale of trips anticipated with the projected population size. Instead, participants perceived that in Melbourne by 2050, there will be less work-related travel due to greater job flexibility and WFH. More localised neighbourhood living (20-minute cities), with most short trips undertaken by active travel, and longer trips by public transport. Furthermore, it was projected that regional centres will grow and the transport system will be for the whole state of Victoria and not just Melbourne. Finally, the study identified short term (2021–2030) travel behaviour priorities and eight immediate actions, including: urban design focusing on inspiring active travel; reallocating road space to prioritise active and public transport modes; planning for micromobility urban freight; improving public transport services; expanding public transport networks; installing electric vehicle charging infrastructure; supporting WFH to encourage trip avoidance; and encouraging political consensus when building major transport projects. • A transport vision and immediate actions for Metropolitan Melbourne (Australia). • Private motor vehicles are not the solution for the scale of trips anticipated. • Local living with short trips by active travel and longer trips by public transport. • Less work-related travel with greater job flexibility and working from home. • Regional centres will grow, and the transport system will be for the whole state.

The continuing growth in passenger transport and the associated increase in CO 2 emissions remain major challenges for our society. Shifting passenger transport to more sustainable modes of transportation contributes to addressing this challenge. Multimodal transportation hubs (MMTHs) coordinate and integrate different modes of transportation by improving transfers between them. In addition, MMTHs offer a high quality of stay with a wide range of services, as well as a compact, mixed-use urban development with a high density of uses around them. The transformation of railway stations and their environments into MMTHs is addressed in discussions of transit-oriented development (TOD) and the concept of "node and place." However, there is a lack of a systemic approach that structures the problem involving the different worldviews of the actors. In addition, the necessary changes and measures are largely unknown. Based on the soft systems methodology (SSM), we conducted 20 SSM interviews and two SSM workshops (n = 10 each). Our results show that the problem can be structured into the three layers of "national long-term integrated optimization of the passenger transport sector and spatial development," "local short-to medium-term planning and implementation," and a "regional, bidirectional transfer by policy-making and planning." The transfer layer between the national, long-term and local, short-term worldviews is key and must be strengthened. Furthermore, we present systemically desirable and culturally feasible measures for each layer to improve the current situation of the transformation—a national MMTH program, creating an overarching vision, a caretaker for local implementation to coordinate the interests of actors, and collaborative development of regional master plans and an explorative approach to ensure bidirectional exchanges between the national and local layers. Although the structuring of the problem and the measures were developed from a Swiss viewpoint, we expect that the results will also be useful for other decentralized states. • Structures the problem of transforming railway stations and their surroundings into multimodal transportation hubs (MMTHs). • Help actors responsible or affected to perceive different worldviews and develop a common understanding. • Present systemically desirable and culturally feasible measures to improve the current situation of the transformation. • A regional "bidirectional transfer layer" between the local, and the national worldviews needs to be strengthened.

PLANNED behavior theory , *PUBLIC transit , *MIDDLE-income countries , *URBANIZATION , *CHOICE of transportation , *LOCAL transit access - Abstract
Perceived accessibility refers to individuals' subjective perception of how easy it is to reach destinations using a specific mode of transport. As such, understanding the effect of perceived accessibility on travel behavior is essential for creating transport systems and urban environments that are efficient, equitable, and sustainable. This study develops a new integrated model by combining the Norm Activation Model (NAM), the Theory of Planned Behavior (TPB), perceived risk, and perceived accessibility. This enhanced model offers a comprehensive understanding of the factors influencing individuals' intentions to switch to urban train systems. Additionally, the moderating effects of perceived accessibility on the link between personal, contextual factors and switching intention are also explored. The model developed is tested using data obtained from a sample of 535 individuals in Hanoi, Vietnam. This is particularly important because more research in low- and middle-income countries (LMICs) is needed to address the sustainability challenges these nations face due to their dependency on motorized private transport. The findings show that subjective norms have the strongest effect on the intention, followed by personal norms, attitude, and perceived accessibility. This study also confirms the moderating role of perceived accessibility on the link between attitude and switching intention, while the other hypotheses regarding the moderating effects of perceived accessibility are not supported by the findings. These insights aim to inform policymakers and public transport authorities in developing targeted strategies to promote sustainable urban mobility in Vietnam. [ABSTRACT FROM AUTHOR]

• Dynamic bidirectional effects between perceived accessibility and travel decisions. • Effects differ based on transport mode and whether considering behavior or preference. • Perception-behavior theory aligns more with revealed behavior than stated preferences. • Unlike conventional wisdom, travel behavior greatly impacts perceived accessibility. • "Travel behavior" shows less perception-behavior "dissonance" than "travel preferences." In theory, the unidirectional relationship between perception and behavior has been well established. In this line, the relationship between perceived accessibility and travel behavior has also gained traction in the transport domain. There is, however, less knowledge regarding the dynamic of bidirectional effects between these two variables and (in)consistency over time. Employing the Netherlands Mobility Panel data, we investigate the direction of the (causal) effect between perceived accessibility and travel behavior/travel preference. Using a two-wave cross-lagged panel model, we test how this theory works among urban travelers (n = 4,946). The findings show that the relationship between perceived accessibility and travel-related decisions varies depending on the transport mode and whether it is about travel behavior or preference. The effects might show bidirectionality, unidirectionality, or neither. Findings highlight that the perception-behavior theory is primarily consistent with revealed travel behavior as opposed to stated preferences. We find a bidirectional perception-(travel) behavior relationship. Unlike conventional wisdom and commonly used theoretical links, we find that travel mode use has a larger impact on perceived mode-specific accessibility than the reverse effect (the more expected link). Travel behavior also shows consistently lower levels of perception-behavior dissonance than preferences do. The study finds that perception consistently influences public transport use and preferences, unlike for cars and bicycles. Policy-wise, this implies that efforts aimed at correcting misperceptions about the accessibility of public transport could still have a positive impact on individuals' decisions to choose public transport.

Germany, aligned with the European Union, has set important targets for decreasing greenhouse gas emissions by 65% by 2030 and achieving climate neutrality by 2045. In this context, Power-to-X fuels have emerged as promising solutions for defossilizing transport modes less suitable for electrification. However, a significant challenge in developing Power-to-X fuels is the lack of a well-defined regulatory framework for their production and utilization. Thus, this study investigates the regulatory landscapes of the EU and Germany, aiming to comprehend objectives, support schemes, and advancements. A total of 25 legal frameworks from the EU and Germany with direct or indirect effects on Power-to-X fuels were identified. For a detailed and comprehensive policy analysis, a qualitative inductive approach based on a coding scheme and policy content analysis, was implemented. Findings indicate that several updates in the German and EU regulatory frameworks addressed Power-to-X fuels in the 2010s and 2020s. The RED III, the REFuelEU Aviation and the FuelEU Maritime have shown to be turning points for Power-to-X fuels in the EU. In Germany, the most relevant policies are the 37. BImSchV, the National Hydrogen Strategy, and the PtL Roadmap. Key challenges are identified related to the limited coherence among policies supporting the sustainable use of resources for the fuel production. • Reviewing cross-sectoral legal frameworks in Germany and the European Union. • Identifying direct or indirect targets addressing PtX fuels in transport. • Analyzing policies to identify challenges and opportunities. • Presenting status quo of PtX deployments, national and international initiatives. • Proposing recommendations on promoting the production and use of PtX fuels.

Crises are an opportunity to learn, and transportation is no exception. The dramatic reduction in mobility levels during COVID-19, the slow recovery of transit ridership and new trends such as remote working have raised essential questions for the future of public transport. Our work focuses on transit rider segmentation, understanding the heterogeneity of users based on their behaviour before, during, and coming out of the pandemic, and what that means for the economic and social sustainability of transit systems. We asked ourselves two main questions: (i) will people continue riding transit after COVID-19? and (ii) what are riders' reasons behind increasing, maintaining, or decreasing public transport use? Using a two-wave survey conducted in 2020 and 2021, we assessed the motives behind future public transport use in two Canadian cities (Toronto and Vancouver). We used quantitative and qualitative methods, particularly latent class cluster analysis (LCCA), text mining, and qualitative content analysis. We identified six transit riders' profiles, ranging from those experiencing transport poverty who rely on public transport to those more resourced users who will ride less since they can choose alternatives such as remote work, private modes, or active travel. We discuss the policy and practice implications of these results, focusing on what public transport decision-makers should prioritize to benefit disadvantaged groups and recover ridership.

Yavas, Volkan and Ozhan Dedeoglu, Ayla
- Abstract
Despite its substantial customer value in enhancing mobility and connectivity, air transportation prompts concerns regarding sustainability across social, economic, and environmental dimensions. Recognizing the sustainability challenges in Turkey's domestic air travel market and emphasizing the importance of assessing passenger perspectives to ensure regulatory effectiveness, this study investigates how environmental attitudes, perceived value, and satisfaction influence customer preferences. Results from the structural path model analysis highlight the significant impact of emotional value, reliability, comfort, and customer value on air travel satisfaction, affecting both current and future preferences. Gender moderates the influence of safety on satisfaction, with women perceiving it as more critical. While Turkish domestic air passengers express significant environmental concerns, these concerns do not always translate directly into their travel preferences. [ABSTRACT FROM AUTHOR]

Mobility as a Service (MaaS), a rapidly growing smart mobility concept, has the potential to achieve this goal. However, measuring societal impacts of MaaS considering vulnerable social groups' (elderly, disabled, low-income people) needs is still a question for scholars, practitioners, and policy makers. This paper presents a practical 3-stage framework to evaluate the accessibility and inclusion of MaaS systems based on a range of indicators, and a multi-criteria decision making (MCDM) method. A worldwide experts' view survey was conducted among transportation academics and practitioners with 105 valid responses to prioritise the main and sub-criteria in proving an accessible and inclusive MaaS system. The results of MCDM analysis show that accessible transport services, accessible MaaS platforms, and accessibility data collection have a share of 51 %, 29 %, and 20 %, respectively. The functionality of the proposed framework has been illustrated on a real-world multi-city MaaS implementation within the Solent area, in particular Portsmouth city located in Southeast England (UK). The policy recommendations proposed in this study shed light on guiding stakeholders and policymakers to select and implement an accessible and inclusive MaaS system. • Mobility as a Service (MaaS) has the potential to contribute to socially sustainable mobility in cities. • A 3-step MCDM framework and a set of indicators are developed to evaluate inclusivity and accessibility of MaaS. • A worldwide experts' view survey was conducted among transportation academics and practitioners to rank criteria and sub-criteria. • Accessible transport services, accessible MaaS platforms, and accessibility data collection have a share of 51%, 29%, and 20%, respectively. • Functionality of the proposed framework is tested on a real-world MaaS project in the UK.

Washington, District of Columbia (DC), like many cities around the world has responded to the UN's call to help national governments deliver on their 2030 Nationally Determined Contribution (NDC) covered under the UN's sustainable development goal #13, Climate Action. DC's contributions to the United States NDC include making its transportation sector sustainable. DC is part of the Washington Metro region which includes jurisdictions in Maryland and Virginia and during the week commuters from both states increase DC's population by almost 80 % exacerbating traffic congestion. Each jurisdiction in the region is responsible for its financial, transportation, and land use policies. To determine whether this system of fragmented governance impacts DC's transportation goals, this study used Banister's sustainable mobility framework to analyze transportation projects constructed or implemented in jurisdictions in the region. The results reveal that fragmented governance has led to jurisdictions in Maryland and Virginia placing greater emphasis on transportation projects that widen, extend, or create new roads and this tends to meet neighborhood or county needs instead of regional targets which would facilitate DC's efforts to reach its sustainable development goals. The study also finds regional agencies such as the Metropolitan Washington Council of Governments, the National Capital Region Transportation Planning Board, and the Transportation Land-Use Connections Program do not have regulatory powers and hence cannot enforce transportation and land use policies nor fund any projects in the region instead each jurisdiction is responsible for its transportation and land use policies. The study also reveals that these regional agencies can be manipulated by local politicians and recommends the creation of a regional governing body that will make decisions on finance, land-use, housing, and transportation and be accountable to constituents and thus avoid interference from local politicians. • Integrating land use and transport promotes sustainable urban development. • To achieve sustainable transportation, cities need metropolitan governance. • Fragmented governance can lead to uncoordinated and contradicting actions.

Inadequate supply of transport infrastructure is often seen as a barrier to a sustainable future for cities globally. Such barriers often perpetuate significant inequalities in who can and who cannot benefit from sustainable transport opportunities, and as a result there is momentum for transformative urban planning to promote sustainable transportation equity. This study introduces a new set of two-dimensional indicators, merging elements of supply and demand, to identify barriers and imbalances in sustainable transport equity. The accessibility indicators, which are generated for bus, rail, and cycle infrastructure, consider the proximity of administrative areas to good quality transport infrastructure, as well as mode-specific demand, to clearly identify areas where the supply of infrastructure is inadequate to support local populations. We present a policy case study for Liverpool City Region, which demonstrates how these indicators can be used in an analytical framework to support transformative urban planning in long-term. In particular, the indicators reveal policy priority areas where demand for sustainable transport is greater than supply, as well as neighbourhoods where multiple transport inequalities are intersecting spatially, highlighting the need for specific types of infrastructure investment to promote sustainable transport equity (e.g. more frequent services, additional cycle paths). Our framework lays the foundations for improved decision-making in urban systems, through development of mode-specific sustainable transport indicators at small area levels, which harmonise elements of supply and demand for the first time.

[Display omitted] • Active mobility (AM) contributes to the mitigation of climate change. • The study offers a methodology to measure the street use environmental impacts. • Refurbishment return environmental rates do not exceed seven months. • Sustainable transportation requires strategies: AM, carpooling, and mass transport. • Measuring the impacts of street use could generate sustainable interventions. Active mobility (AM) is a fundamental part of a sustainable mobility system that generates environmental and social advantages; however, its use and operation are understudied using quantitative tools such as life cycle assessment (LCA), especially in the Latin American context. This study aimed to analyze the use stage of a street located in Northern Mexico. Two real scenarios were compared, one conventional (CO-SC-2020) and another sustainable (SU-SC-2022), which incorporated the concept of "complete streets" through a bicycle lane and the improvement of pedestrian spaces. Available data from the "Vía Libre" project and PIMUS, as well as SIMAPRO and Ecoinvent, were used for the LCA. The results indicated that the environmental impacts derived from transportation could be reduced through strategies such as active mobility (6.55%) and carpooling (77%), favoring the conversion of cities that consider the automobile as the guiding axis to more sustainable, inclusive, and safe cities.

- Abstract
This paper identifies the state-of-the-art key aspects for the development of mobility-as-a-service (MaaS) ecosystems and provides evidence on the importance of cyber security which has been broadly overlooked in the literature. The analysis is carried out in three stages: (i) a literature review, (ii) a presentation of expert workshop findings, and (iii) a synthesis of both findings to develop a research agenda on cyber security aspects of MaaS ecosystems. The review identifies and bridges the gap between two strands of MaaS literature: the studies that focus on the factors that drive the development of MaaS, and those that create narratives of future MaaS scenarios. The analysis employs the Business Model Canvas to synthesise important factors that underline the development of MaaS in a 7-dimension matrix. This matrix is then used to assess to what extent the available MaaS scenarios cover such dimensions, showing that the literature has overlooked the incentives for users, incentives for MaaS providers, public governance and cyber security elements of the MaaS development. Finally, this paper synthesises the findings from the review of the literature and an expert workshop to develop a research agenda to characterise and analyse the role of incentives to influence the individuals' and organisations' data sharing preferences and emerging cyber security risks in MaaS ecosystems, which will be of interest to both scholars and policymakers. Only through explicit consideration of data-sharing behaviours and risks across individuals and organisations that MaaS ecosystems can support the transition to a net-zero economy. • A 7-dimensional matrix designed for the development of mobility-as-a-service (MaaS). • MaaS scenarios found in the literature are assessed based on the 7-D matrix. • Cyber security introduces challenges in all other six dimensions. • An expert workshop contextualises the findings for the UK. • A research agenda for studying cyber security risks in MaaS ecosystems is proposed.

• This study updates knowledge surrounding transport policies. • A wide range of transport policies is evaluated. • Three policy components are identified: "traditional pull policies", "car-based push policies" and "emerging policies". • The LCA uncovers six distinct classes, illustrating a spectrum of preferences and attitudes. • The findings show potential for more radical transport policies compared to today's policy landscape. The current study contributes to the literature by exploring the acceptance and controversy surrounding different transport policies, examining how public preferences/attitudes explain these dispositions in the context of transitions towards more sustainable transport systems. A random and representative Norwegian-population-based sample (n = 1002) was used for the analysis purpose. A two-fold approach is employed. A principal component analysis is performed first to determine which transport policies (20 policies) are homogeneously evaluated. Secondly, a latent class analysis is used to classify unobserved subgroups of people and distinguish classes of acceptance/controversy patterns. We identify three distinct components of public evaluations of transport policies: "traditional pull policies" focusing on non-restrictive strategies such as incentives for public transport; "car-based push policies" focusing on actively limiting car use; and "emerging policies" focusing on innovative technologies such as electrification and automation. The latent class analysis uncovers six distinct classes, illustrating a spectrum of preferences and attitudes. These classes encompass individuals ranging from strong opposition and neutrality to strong support for various policy types. A highly environmentally conscious class, characterized by higher education levels, strongly supports diverse transport policies, including push and emerging measures, showcasing a commitment to sustainability and readiness for personal sacrifices. However, challenges arise from a class that strongly opposes all types of policies, including traditional pull measures. This class exhibits robust expectations and concerns about policy (features) impacts such as clarity, effectiveness, and fairness, and it is skewed towards a higher proportion of men, with relatively older members. Moreover, they have concerns that such policies might cause adverse consequences for them, such as additional travel time and reduced social interactions. In conclusion, the diverse patterns identified within the population highlight the need for a comprehensive approach to developing transport policies. For the transition towards more sustainable transport systems, the findings show potential for more radical transport policies compared to today's policy landscape. [ABSTRACT FROM AUTHOR]

• Climate change concern can contribute to reduced car use and sustainable mobility. • Those worried about climate change were more willing to live without a car. • Relationship between climate change concern and car use differs based on type of car. • Worry about climate change was strongly related to lower use of a conventional car. • Worry about climate change was unrelated to the use of an electric car. Climate change concern has been linked to climate-friendly behavior, but little is known on whether and how it may promote sustainable mobility. This paper investigates how worry about climate change relates to attitudes and intentions towards the car as well as the actual use of conventional and electric cars in Oslo and Viken in Norway. Findings indicate a relationship between worry about climate change and reduced car use, mediated by mode preferences and willingness to live car-free. Those concerned about climate change were less likely to commute by a conventional car and used conventional cars less both on weekdays and weekends. Worry about climate change was also related to living in a denser neighborhood, preference for travel modes other than the car, and willingness to live car-free. Raising greater awareness of climate change could contribute to climate change mitigation by promoting car-reduced or car-free lifestyles and sustainable mobility. [ABSTRACT FROM AUTHOR]

Mobility is currently undergoing a substantial transition, with emerging mobility modes holding the potential to reshape how individuals move within cities. Using a Norway-wide survey, we uncover latent subgroups of mobility patterns by examining current travel behaviors and (anticipated) future preferences across a range of alternatives, encompassing both conventional and emerging modes. The level of behavior-preference dissonance (i.e., non-alignment), various travel needs (e.g., safety, environment, cost), and sociodemographic variables are considered covariates. Results uncover seven distinct mobility classes ranging from current (un)sustainable use (behavior) to (un)sustainable future preferences. There is a noticeable preference for electric vehicles (EVs), while autonomous vehicles are less popular. Policymakers should navigate the transition to EVs with caution, ensuring that the integration of EVs complements rather than displaces active travel. In a class, despite indicating a desire for more (emerging) sustainable options, they paradoxically anticipate making more trips than other groups, potentially offsetting their environmental impact.

- Abstract
• Current trends in air transport are inconsistent with international climate goals. • Academics feature prominently among frequent flyers. • Academics of UCL are clustered based on their opinions of academic travel. • Results show that some academics seem forced to regularly fly to distant locations. • We offer tailored policy instruments to reduce the impact of – and need to – travel. Current trends in air transport are inconsistent with international climate goals. Without substantial changes from business-as-usual travel demand, neither new technologies nor alternative fuels will reduce emissions at the required rate. Air transport demand is highly skewed towards a small share of frequent flyers in all aviation users. While the unsustainability of aviation is well-recognised in academia, academics themselves are often frequent flyers – generating the emissions many of them also problematise. To investigate this contradiction, we survey 1,116 staff members from University College London (UK). We cluster academics based on their opinions of academic travel and international conference organisation, and examine how these groups participate in, and travel to, academic activities. Five clusters are identified: 1) Conservative frequent flyers , 2) Progressive infrequent flyers , 3) In-person conference avoiders , 4) Involuntary flyers , and 5) Traditional conference lovers. Despite some levels of similarity between academic travel attitudes and behaviour, results show that certain types of academics seem forced to regularly fly to distant conferences. In fact, members of our largest cluster (Involuntary flyers) have negative attitudes towards flying, yet have the plane as dominant travel mode. To reduce academic air travel (dependency), we provide tailored policy instruments for each cluster, aimed at reducing the need to travel to lowering the impact of travel. [ABSTRACT FROM AUTHOR]

We develop a microeconomic model of competition between ridesourcing, public transport, and cruising taxis to analyse how alternative ridesourcing regulation policies affect not only the ridesourcing service but also other modes of transport. To maximise social welfare in a framework with congestion externalities, we analyse three alternative regulation policies (i) a charge as a percentage of the ridesourcing trip fare (ii) a fixed charge per ridesourcing trip, and (iii) a fixed charge per ridesourcing vehicle. A randomised search algorithm is programmed and simulations are performed considering the base case of the Metropolitan Region of Santiago de Chile. We find that for the case of speeds below 9 km/h, the market power of the platform is dominated by the congestion externality effect, which leads to an optimum where the regulator charges a tax to the platform. In turn, waiting time for ridesourcing increases, but congestion decreases. Lower congestion scenarios lead to a ridesourcing subsidy, in which the regulation policy increases the number of ridesourcing drivers and reduces waiting time, at the cost of increasing congestion. For a given scenario (either low-congestion or high-congestion), we find that the profits of the agents involved (ridesourcing platform and drivers, taxi drivers, and bus operator) are sensitive to the type of regulation applied, however the total social benefit and consumer surplus are largely insensitive to the regulation adopted, therefore policymakers could take into account, for instance, the effects on the financial situation of the public transport sector when deciding which type of regulation instrument to apply to the ridesourcing sector.

Motivating active transport is a health and environmental policy priority, and plays an important role in achieving the necessary shift toward a sustainable transport system. Financial incentives to promote cycling are used in many countries, but very few studies document causal effects. Using a randomized controlled trial in the field, we provide causal evidence of the effect of different types of economics incentives on cycling activity in Norway. Participants' mobility is monitored through an innovative mobile app that registers travel behavior automatically. Results show that both a flat rate and a conditional lottery motivate people to cycle more. Compared to the control group, participants who received an economic incentive cycled 36% more and 18% more often. The conditional lottery appears to be an effective and economically efficient solution and the only treatment with a lasting effect after the incentives were removed. [ABSTRACT FROM AUTHOR]

CHOICE of transportation , *CYCLING , *ACCELEROMETERS - Abstract
• The first meta -analysis to synthesize interventions to promote cycling. • On average, interventions to promote cycling have small but significant effects. • Self-monitoring and adding objects are useful techniques to promote cycling. • Psychosocial interventions are more effective than changes to infrastructure. • Interventions that target specific groups produce larger effects. Cycling has the potential to address a number of personal and societal challenges, not least with respect to health and the need for more sustainable modes of transport. However, the best way(s) to promote cycling is still unclear. In an effort to answer this question, we identified 39 interventions designed to promote cycling, with a total sample of 46,102 participants. Random effects meta-analysis estimated a small but statistically significant effect of interventions on cycling behaviour (g + = 0.14, 95% CI [0.05, 0.23]). To identify the most effective intervention strategies, we coded the behaviour change techniques used within each of the interventions. Interventions that prompted people to self-monitor their behaviour or added objects to the environment (e.g., provided shared bikes) were more effective than those that did not use these strategies. Interventions that restructured the physical environment (e.g., built new cycle paths) were less effective than the studies that did not do this. We also identified a number of factors that moderated the effect of the interventions on outcomes; specifically, interventions that targeted a specific group, used objective measures of cycling such as accelerometers, and that were tested using independent groups designs typically yielded stronger effects. The findings should help to guide interventions to promote cycling in the future. [ABSTRACT FROM AUTHOR]

Environmental protection and counteracting the effects of global warming have become an important topic of political debate in many countries, especially in Europe. One of the main challenges they face is changing the transport system, which is responsible for a significant proportion of harmful emissions. To achieve this, in addition to improving navigation conditions, inland navigation should be included in the modern intermodal transport chain. The analysis showed that activities in this area should be carried out in two stages. First, it is necessary to meet the boundary condition, i.e., to ensure the appropriate parameters of the waterway, and then it is necessary to implement ICT systems in order to standardize and streamline the process of data transmission between the stakeholders of inland navigation (water and shipping administration, port and terminal managers, shipowners and ship crews). The article presents the status of work on the implementation of the RIS system in Poland and the prospects for its further development, including the enlargement of the area covered by the system, and analyzes the possibilities of implementing new tools dedicated to ship captains and inland shipowners. An important element of the work is to indicate the benefits of using the RIS system by transport companies and the costs of its use. [ABSTRACT FROM AUTHOR]

ELECTRIC vehicle charging stations , *ELECTRIC vehicles , *SUSTAINABLE transportation , *TRAFFIC density , *LINGUISTIC context , *ECOLOGICAL impact - Abstract
The adverse effects of traditional vehicles on the environment increase the demand for clean vehicles, such as electric vehicles (EVs). The correct positioning of the charging points for such vehicles certainly promotes the acceptance and spread of EVs. Indeed, selecting optimal locations for electric vehicle charging stations (EVCS) is crucial for shaping a sustainable future. This study introduces an integrated methodology under a double hierarchy linguistic context with a criteria importance through an inter-criteria correlation (CRITIC) technique for experts' reliability determination, an attitudinal Cronbach's method for criteria weight estimation, and a novel multi-criteria technique considering the compromise ranking of alternatives from distance to ideal solution (CRADIS) formulation for optimal EVCS location selection. Based on the results, criteria such as service capability, ecological impact, land cost, and traffic density are the most crucial, with Manapparai, India, as the optimal location for a new EVCS construction. Further, a crucial finding is that the social dimension is substantial compared to the economy and environment dimensions for EVCS location selection. The novelty of the paper is that (i) uncertainty and expression of choices in natural language form for locations for EVCS are modeled effectively using a double hierarchy structure, (ii) experts' weights are obtained methodically by considering hesitation and interactions among experts, (iii) interdependencies among criteria and importance of experts are considered during criteria weight determination, and (iv) locations are ranked by not only considering criteria type but also resembles closely to the human-centric decision process. A detailed sensitivity analysis is further conducted to prove the proposed approach's effectiveness and stability. In the context of sustainable transportation, the work could contribute to the relevant literature through a powerful decision-making tool. [Display omitted] • Preferences in the natural language are modeled as complex expressions. • Experts' reliability are methodically determined with interaction measures. • Criteria weights are calculated via attitudinal-Cronbach method. • Double hierarchy CRADIS is proposed for ranking sites. • Practicality is testified through site selection for electric vehicles.

In tandem with the urbanisation process, China's transport sector is currently experiencing rapid development and was ranked third out of all the industrial sectors in terms of generating CO 2 emissions in 2020, which poses a huge challenge to achieving carbon neutrality. Primarily using the energy consumption data from China's transport, storage and postal sectors (TSPS) and input and output data between 2007 and 2020, this study first uses the Tapio decoupling model to evaluate the decoupling effect in the TSPS. Structural decomposition analysis is then applied to explore sectoral linkages and decompose the forces driving CO 2 emissions. Additionally, we explore the main determinants of the energy structure effect and final demand in terms of energy consumption and industrial sector demand. Our results show that the target sector experienced a weak decoupling, which implies that the low-carbon transformation of this sector became increasingly apparent. Factor decomposition shows that improvements in energy intensity, energy structure and the production input and output structure have contributed significantly to reducing CO 2 emissions, but these gains have been largely offset by final demand, resulting in a net reduction of 27.97 million tons from 2007 to 2020. The increased usage of low carbon forms of energy, such as natural gas, is the key driver behind the emissions reduction effect in terms of the energy structure. However, the higher final demand from the construction sector and the wholesale and retail trades are the main factors that have increased CO 2 emissions. By adopting a sectoral and energy structure decomposition perspective, our study can be used to provide guidance to governments seeking to pursue carbon-reduction policies to achieve carbon peak and carbon neutrality, in the TSPS in particular. • Structural decomposition analysis is used to quantify the driving forces behind increasing CO2 emissions. • A decrease in energy intensity is vital to achieve carbon neutrality. • Natural gas is the main driver of reducing emissions in terms of energy structure. • Demand from specific industrial sectors is the main barrier to achieving carbon neutrality. • A pathway for achieving carbon neutrality in the transport sector is proposed.

- Abstract
Over time, rail's share of the freight market has steadily decreased and, currently, is significantly lower than that of the road. This study explores what fosters shippers' rail dispreference. The study is conducted in the domain of outbound logistics in the steel-making industry in India. Twenty-one industry experts are interviewed in-depth to capture their perceptions, and their responses are analysed. Of these, seven are industry experts, and the remaining fourteen are logistics managers working across two steel plants, among which the annual output of one is about ten times that of the other. We find that a capacity shortage in the rail sector and the monopoly position of the rail transport provider together foster multiple factors that drive shippers' rail dispreference. Further, shipper firm size moderates the influence of some of these factors, influencing shippers' rail dispreference to a lesser extent in the larger firms than in the smaller ones. The study highlights the realization that while increasing rail capacity is necessary, it is not enough by itself, but must be complemented by targeted policy changes. The study brings to the forefront the roles played by rail capacity shortage, rail monopoly position, and shipper firm size in shippers' rail dispreference. • This study explores what fosters shippers' rail dispreference.

Taxi ridesharing (TRS) systems are considered one means towards more sustainable transportation by increasing car occupancy rates and thereby significantly improving the efficiency of urban transportation systems. In this study, we consider TRS with shared pick-up and drop-off locations, where customers of a shared trip might be required to walk a short distance from their origin/to their destination. Related research has discussed the advantages of this approach over other TRS variants, including shorter travel times, lower fuel consumption and fewer emissions. However, these studies do not investigate how a TRS ought to be designed under different environmental conditions to maximize its effectiveness in terms of rejection and sharing rate. We contribute to closing this gap with three achievements. First, we propose a new mathematical model that provides a conceptualization of the TRS problem with shared pick-up and drop-off locations. Second, we implement a rolling horizon approach and conduct extensive computational experiments based on empirical data from New York City and Porto. In our experiments, we vary and combine several exogeneous (environmental) and design-oriented factors and show that both exert considerable influence on the rejection rate, sharing rate and service quality. Third, for practitioners considering a TRS with shared pick-up and drop-off locations, our guidelines highlight the importance of system design, particularly in leveraging extended waiting times to attain low rejection rates and foster high sharing rates. • Math. model for taxi ridesharing (TRS) with shared pick-up/drop-off locations • Rolling horizon solution approach to account for uncertainty of future requests • Experiments on real data from NYC and Porto with simulation of a limited taxi fleet • Analysis of system's effectiveness sensitive to design and exogenous parameters • Guidelines for practitioners who plan to design and implement TRS systems [ABSTRACT FROM AUTHOR]

• An international benchmarking of ferry operation and pier infrastructure is proposed. • Passenger-related and operator-related factors are examined. • Improving passengers' travel and multimodal transfer experience is fundamental. • Government investment in pier infrastructure and waterfront amenities is recommended. With rapid road infrastructure development in the past century, the role of water passenger transport has diminished drastically worldwide. A lot of ferry services in coastal cities have become financially unviable. However, water transport has huge potentials in promoting transport sustainability and resilience. This paper proposes a holistic framework that examines five core elements in a ferry business model, including (i) population demand, (ii) connectivity to public transit and activity nodes, (iii) individual preferences, (iv) management and operational strategies and (v) pier infrastructure. An international benchmarking framework of ferry operation and pier management across several cities with large-scale ferry development (Brisbane, Hong Kong, London, New York, San Francisco and Venice) is proposed and tested in Hong Kong. There are several general lessons. First, providing denser and more diversified opportunities (employment, commercial, recreation and open space) near the piers with good connectivity is essential. Direct access to these activities by water transport and well-developed intermodal transfer are conducive to ferry patronage. Second, improving the travel experience of passengers, including pre-boarding and on-board experience, is fundamental. Overall, integrating ferry services, pier infrastructure and promenade development in a policy package is critical to the long-term viability of ferry transport, although several critical challenges need to be addressed.

The European Union (EU), as well as many national governments, has adopted directives intended to reduce the environmental impact of transport. For example, the EU's clean fuel strategy requires member states to develop national policy frameworks for the market development of alternative fuels and their infrastructure. Given these directives, policy solutions must be formulated and proposed by member states. This paper focuses on the policy adaptation phase of a policy process, specifically on administrators' knowledge-making when constructing policy proposals. The paper combines policy theory with planning theory and provides a theoretical framework for studying policy adaptation, specifically, administrators' construction of knowledge in such processes. The empirical study is based on two cases, both situated in the Swedish context. It concludes that administrators use several sources of knowledge: process knowledge, project knowledge, and context knowledge. New policy solutions are constructed by reusing data from existing reports and policy proposals. There has been a specific focus on the use of economic analysis as an instrument for evaluating solutions. The paper shows that, in the policy adaptation phase, no new analyses are conducted and that decoupling strategies are used when dealing with economic analysis. [ABSTRACT FROM AUTHOR]

A large and growing body of evidence suggests fundamental changes are needed in transport systems, to tackle issues such as air pollution, physical inactivity and climate change. Transport models can play a major role in tackling these issues through the transport planning process, but they have historically been focussed on motorised modes (especially cars) and available only to professional transport planners working within the existing paradigm. Building on the principles of open access software, first developed in the context of geographic information systems, this paper develops and discusses the concept of open access transport models, which we define as models that are both developed using open source software and are available to be used by the public without the need for specialist training or the purchase of software licences. We explore the future potential of open access transport models to support the transition away from fossil fuels in the transport sector. We do this with reference to the literature on the use of tools in the planning process, and by exploring an example that is already in use: the 'Propensity to Cycle Tool'. We conclude that open access transport models can be a leverage point in the planning process due to their ability to provide robust, transparent and actionable evidence that is available to a range of stakeholders, not just professional transport planners. Open access transport models represent a disruptive technology deserving further research and development, by planners, researchers and citizen scientists, including open source software developers and advocacy groups but, in order to fulfil their potential, they will require both financial and policy support from government bodies. • New technologies provide opportunities for more participatory and evidence-based transport planning. • The concept of 'open access transport models' is developed and defined as being both open source and accessible. • Open access transport models can widen participation in the planning process and help develop better solutions. • Further work is needed to identify priorities for future development and to design new open access transport models. • Government support is needed to embed open access transport models in transport planning organisations and processes.

• A bicycle superhighway is proposed for an urban area. • Algorithm to identify optimum number and locations of bicycle superhighway connectors. • Household income is included in the decision-making process of individual travellers. • The potential of increase in bicycle share is quantified. • Impact of BSH on emissions and accessibilities is visualised for policy implications. Bicycle is a sustainable low-carbon transport mode. However, insufficient or unplanned infrastructure leads to decrease in the share of bicycle in many cities of developing nations. In order to increase the bicycle share and to provide safer, faster and more direct routes, a bicycle superhighway is proposed for urban areas. This study identifies the potential of increase in the bicycle share. For maximum utilization of the new infrastructure, an algorithm is presented to identify the optimum number and locations of the connectors between proposed new infrastructure and existing network. Household income levels are incorporated into the decision making process of individual travellers for a better understanding of the modal shift. A real-world case study of Patna, India is chosen to show the application of the proposed superhighway. It is shown that for Patna, the bicycle share can escalate as high as 48% up from 32% by providing this kind of infrastructure. However, together with bicycles, allowing motorbikes on the superhighway limits the bicycle share to 44%. The increase in bicycle share is mainly a result of people switching from motorbike, public transport and walk to the bicycle. Further, to evaluate the benefits of the bicycle superhighway, this study first extends an emission modelling tool to estimate the time-dependent, vehicle-specific emissions under mixed traffic conditions. Allowing only bicyclists on the superhighway improves congested urban areas, reduces emissions, and increases accessibility. However, allowing motorbikes on the superhighway increases emissions significantly in the central part of the urban area and reduces accessibilities by bicycle mode to education facilities which are undesirable. This study elicits that a physically segregated high-quality bicycle superhighway will not only attract current non-cyclist travellers and increase the share of the bicycle mode, but will also reduce negative transport externalities significantly.

- Abstract
In the pursuit of transforming the transportation sector towards sustainability, a technological shift in vehicle drive systems is being promoted worldwide. Conventional gasoline or diesel fueled cars powered by internal combustion engines (internal combustion engine vehicle, ICEV) are to be replaced with alternative cars that are electrically driven (electric vehicle, EV) and powered by a battery, which is either externally charged (battery-electric vehicle, BEV) or internally charged via a hydrogen fuel cell (fuel cell electric vehicle, FCEV). However, whether or not EVs are superior to ICEVs throughout their entire life cycle is still subject to debate. Though considerable numbers of environmental life cycle assessment (eLCA) studies and—to a much lesser extent—life cycle costing (LCC) and social life cycle assessment (sLCA) studies have already been conducted, their individual results alone do not allow decision-makers to draw conclusions concerning the overall sustainability performance of the various vehicle technologies. Therefore, we are presenting a novel approach to analyze ICEV-, BEV-, and FCEV-type passenger cars on a multidimensional basis. This approach is based upon and combines existing studies about eLCA, LCC, sLCA, and further assessments to carry out a comprehensive meta-analysis by using multi-criteria decision making (MCDM) methods. Through a transparent and differentiated presentation of the results, the adopted approach furthermore enables decision-makers to identify specific aspects influencing the overall performance of each vehicle technology and to take measures that allow for the implementation of sustainable vehicle concepts. © 2020 The Authors.

E -bike use in rural and tourist areas is under-researched and has potential to replace car journeys reducing greenhouse gas emissions and other impacts of car use. We studied the rural use of e-bikes in a tourist area (the Lake District National Park, UK) through Covid-19. Mixed methods were used; two waves (2020 & 2021) of a semi-panel quantitative survey; including open responses; supplemented by self-study field trips. Key findings include high levels of e-biking in a wet and hilly area by generally older individuals, including a high proportion of female respondents. Usage was higher in 2020, partly due to lower traffic levels during Covid restrictions, but relatively high usage was maintained in 2021. Users are substituting more car journeys than active travel and public transport trips, and amongst women, more errands than commutes. We found support for restraint of car use in the study area, along with support for secure e-bike parking, e-bike share schemes, and integration with public transport. The implications for planners and policymakers are that policies supporting rural e-biking may be well received if they form part of greener transport plans including e-bike facilities, integration with public transport and car restraint. Promotion of e-bike use needs to shift from an urban commuting focus, to also consider rural areas errands and leisure trips. National parks and other rural tourist areas may confidently assume that hills and weather do not always act as barriers. • E -bikes are being used to reduce car travel in a touristic, rural wet and hilly area and have decarbonisation potential. • There is support for car restraint in a UK National Park and a desire for secure e-bike storage. • E -bikes are being used for errands as well as commuting in a rural National Park. • Relatively high levels of use and support for e-bikes continue after easing of Covid restrictions in 2021.

43. Exploring Low-Carbon Bus Options for Urban BRT Systems: The Case of Amman.

Imam, Rana, Seong-Cheol Kang, and Quezada, Diana
- Abstract
Being able to provide high-quality, metro-like transit service at a fraction of the cost of other options, bus rapid transit (BRT) has been viewed as one of the most cost-effective public mass transport systems suitable for urban areas. Since significant amounts of greenhouse gas (GHG) and air pollutant emissions are attributed to the transport sector, deploying low-carbon buses for BRT systems should be of high priority. With a view to promoting low-carbon buses instead of diesel buses for a BRT system currently being planned in Amman, Jordan, this paper evaluates several low-carbon bus options--hybrid, plug-in hybrid, opportunity charging, trolleybus, and battery electric bus--against the baseline case of diesel buses. While low-carbon buses reduce GHG and air pollutant emissions often considerably, they usually require higher upfront capital costs and additional infrastructure investments. On the other hand, they tend to incur lower energy and maintenance costs and have a longer lifetime, particularly battery electric buses. All these advantages and disadvantages are included in the assessment of low-carbon bus options relative to diesel buses. For the trunk routes of the Amman BRT, the analysis shows that the opportunity charging bus can be the most appealing option, having a positive internal rate of return (IRR) for the incremental investment costs. For the feeder routes, both low-carbon bus options considered, hybrid and battery electric, do not result in a positive IRR. Nevertheless, the battery electric bus is found to be a comparatively better option than the hybrid bus. A sensitivity analysis was conducted for both trunk and feeder routes to examine the variability of several parameters used in the study, such as capital expenditures, electricity price, and diesel price. The results show that IRR could increase favorably under certain conditions. [ABSTRACT FROM AUTHOR]

In this paper, an in-depth examination of the use of ride-hailing (ridesourcing) in Santiago de Chile is presented based on data from an intercept survey implemented across the city in 2017. First, a sociodemographic analysis of ride-hailing users, usage habits, and trip characteristics is introduced, including a discussion of the substitution and complementarity of ride-hailing with existing public transport. It is found that (i) ride-hailing is mostly used for occasional trips, (ii) the modes most substituted by ride-hailing are public transport and traditional taxis, and (iii) for every ride-hailing rider that combines with public transport, there are 11 riders that substitute public transport. Generalised ordinal logit models are estimated; these show that (iv) the probability of sharing a (non-pooled) ride-hailing trip decreases with the household income of riders and increases for leisure trips, and that (v) the monthly frequency of ride-hailing use is larger among more affluent and younger travellers. Car availability is not statistically significant to explain the frequency of ride-hailing use when age and income are controlled; this result differs from previous ride-hailing studies. We position our findings in this extant literature and discuss the policy implications of our results to the regulation of ride-hailing services in Chile. • The most substituted modes by ride-hailing (RH) are public transport and taxis. • For every RH rider that combines with public transport, 11 riders substitute it. • Probability of sharing a RH trip decreases with income and increases for leisure. • Car availability is not significant to explain frequency of RH use. • Policy implications for the regulation of RH services in Chile are discussed.

The paper presents an in-depth analysis of a novel scheme for the sustainable mobility, based on electric vehicles, photovoltaic energy and electric energy storage systems. The work aims to analyse such innovative system, putting in evidence its advantages in comparison to a conventional one, based on the grid-to-vehicle technology. The study also provides interesting guidelines for potential users and system designers. Two case studies are presented: i) the taxi fleet of the city centre of Naples and ii) the cargo vans of the city of Salerno; both towns are in Southern Italy. For each case, the hourly power consumption of the vehicles was evaluated, as a function of the daily trip length. An accurate procedure was implemented to select the sites suitable for the installation of the charging stations, including a photovoltaic field and an electric storage system. A comparison was also performed between two different electric storage technologies: lead-acid and lithium-ion battery. The case studies were analysed by means of a detailed dynamic simulation model, developed in TRNSYS. A sensitivity analysis was also performed, to evaluate how different values of the most important design and operating parameters affect the system overall performance. It was found that the results are mostly affected by solar field area, capacity of the energy storage system and investment cost. The comparison between the two selected storage technologies did not exhibit significant differences. For both the cases investigated, it was found that, during the summer, solar energy covers an important amount of the total energy demand. On the contrary, in winter the amount of energy provided by the public electric grid was high. From an economic point of view, assuming a lithium-ion battery capital cost equal to 90 €/kWh, acceptable pay-back periods (about 6 years) were obtained, for both the applications considered. • Dynamic analysis of electric vehicle solar parking focused on sustainable mobility concept. • Transport/statistical model development for both private/public transport sector. • Environmental, energy and economic comparison between lead-acid and lithium-ion battery. • Interesting pay-back periods in case of lithium-ion battery capital cost expected reduction.

A tremendous growth has been observed in the use of personal vehicles. Increase in private vehicle use has created many environmental, social and economic problems. A multi-stage trip can help to elevate the problems of delays, environmental degradation, and congestion. Multi-stage trips provide the benefits of smarter, cleaner and sustainable transport. This paper focuses on the organization of different multi-stage trips with respect to first mile, main stage, and last mile and factors that influence the choice of these mode combinations. A multinomial logistic regression (MNL) model is used to evaluate the factors that affect the choice of different mode combinations in a multi-stage trip. For most of the combinations, the trip purpose is significantly associated with mode choice for these combinations. In most cases, availability of the car results in a decline of probability for choosing a combination involving walk. The families with children prefer to take a combination involving a car or public transport at the first or last mile. This study only focuses on the mode combination of 3-stage trips so, an analysis can also be made for multi-stage trips having more than 3 stages. • The multi-stage trip is one of the key solutions to resolve the problem being faced due to high use of private vehicles. • Multinomial logistic regression is used to evaluate the choice between different mode choice combination. • Household income has an influence on the probability of specific mode involving public transport or car for a first and last mile. • The families with children prefer to take combination involving a car or public transport at first or last mile. • It is the matter of fact that one individual link is not enough to mode choice behavior rather combination of different mode is important.

The contemporary urban transport debate is increasingly versed in terms of "sustainable" development, placing social and environmental issues on the agenda. However, despite their heterogeneity, sustainable perspectives seldom engage with the explicitly political issues that shape the relationship between transport and urban development. In this paper, we propose to re-connect urban transport with political economic considerations, and thus to mobilise and strengthen "critical" perspectives on urban transport. We develop a framework for studying transport policies inspired by Henri Lefebvre's conceptualisation of "the right to the city". The framework is illustrated with the empirical example of a "pedestrianisation" project in Brussels, a salient case of a "sustainable" transport policy. We demonstrate how ostensibly progressive intentions in terms of challenging local mobility paradigms do not necessarily translate into participative and transformative practices. Instead, they often embrace the established policy-makers, leave local power relations largely unaltered, support elite entrepreneurial agendas, and obfuscate the socio-spatially uneven landscapes of contemporary cities. We thus highlight the urgency of re-politicising urban transport theory and practice by seeking and revealing political economic choices, contradictions and conflicts that underpin transport policies interwoven with urban development dynamics. • Dominant "sustainable" perspectives on transport seldom engage with political issues. • We propose to re-connect urban transport with "critical" political economic considerations. • We offer a framework for studying transport through Lefebvre's "right to the city". • We illustrate the framework with the example of a "pedestrianisation" project in Brussels.

There is considerable interest in the contribution that workplace-based mobility management interventions can make to achieving more sustainable mobility patterns. A number of studies have evaluated the impacts of workplace-based interventions on the commuting behaviour of staff, but the broader potential of such initiatives depends on the willingness of employers to support them. Little research has been carried out examining the perspectives of senior managers. The research which has been conducted has focused on employers located in urban or rural areas. This paper reports on in-depth interviews with senior managers of employers located in two peri-urban areas on the edge of the city of Bristol, south-west England. The research was carried out during a period when public funding was available to support the introduction of sustainable transport measures. The interviews aimed to find out whether senior managers perceived the promotion of sustainable transport as relevant to their business concerns, and how this varied between different types of organisation. The results showed that all managers believed that measures to increase the use of alternative modes for commuting and local business travel could be beneficial for their business, even if these benefits were indirect and difficult to quantify. The perceived benefits of sustainable transport included: helping to ease traffic congestion on the road network, thereby reducing associated delays and stress; helping employers manage excessive demand for car parking; improving staff wellbeing; and widening the recruitment opportunities among workers lacking access to a private car. Employers who perceived the greatest benefits were also the most willing to engage with public authorities in introducing new workplace-based mobility measures. The findings on employer support for mobility management are relevant not only to peri-urban areas but also to employment sites within other areas (in particular suburban areas and the rural hinterland) where the same challenges may apply of encouraging alternatives to single occupancy car use without the means to invest in comprehensive public transport.

One of the most important problems in the cities is atmospheric emission of anthropogenic origin. This problem is the key challenge mostly for city municipalities but also for business stakeholders, which are involved in freight transport at urban areas. One of the most important and efficient solutions to reduce this negative impact is implementation of electric vehicles. In recent years many activities and developments in this area have been done. This paper is focused on utilization of multi-criteria analysis for electric vehicles selection in the context of their usability for deliveries realization in cities. Moreover, it also presents general issues regarding the use of alternative fuels in motor vehicles, with emphasis on electric vehicles. It discusses the extent to which electric vehicles are used. It describes the key parameters for determining the usability of electric vehicles in urban deliveries. Based on the formulated assumptions, a multi-criteria model is proposed to enable selecting, out of the defined vehicles catalogue, solutions that are optimal in terms of potential effectiveness. The general aim of the paper is to support the logistics companies' decision makers in the improvement of the freight vehicles fleets, taking into account the sustainable city logistics expectations.

We conducted a stated choice experiment with visitors to the Teide National Park (TNP), where a hypothetical park shuttle bus connecting its main points of interest was simulated. Using these data, we estimated a model focused on capturing systematic and random heterogeneity in the park visitors' preferences. We obtained visitors' willingness-to-pay (WTP) for saving time while searching for a parking space (when using cars), and also visitors' WTP for reducing the waiting time required to start the visit in the shuttle bus. Moreover, regarding the environmental impact of the visit, we obtained individuals' WTP for reducing CO 2 emissions. Our results suggest that visitors would be willing to pay nearly 11€ for reducing the time spent finding a parking space and 9€ for reducing the waiting time to start the visit, in one hour; further, they would be willing to pay 3€ for reducing in 20 g the CO 2 emissions per occupant. These values are higher for females, for German visitors and for those who are regular bike riders at their home location. Moreover, we found that visitors aged between 55 and 60 had the highest WTP. These results may be used to design transport management policies for relieving visitors' dependence on personal vehicles, helping to increase the visit quality and reduce the negative externalities associated with current mobility patterns in the park.
