School transportation services are often essential to disabled children's education access. The organisation of school bussing affects their experiences of inclusion and exclusion in educational settings. Disability is often overlooked in active school travel and children's independent mobility research, underscoring the need to examine ableism in school transportation services. This scoping review considers manifestations of ableism in school transportation studies. Findings highlight ableist school transportation elements that families of disabled students experience, such as inadequate educational programming, limited transportation availability, poor transportation service quality and scheduling, and inaccessible schoolyard designs. These issues contribute to inequitable psychological, financial, and administrative burdens for families of disabled students. Scholars are encouraged to explicitly identify and interrogate ableism in future research by employing critical theoretical frameworks that help to recognise and challenge the normalised exclusions it causes in school transportation. Further research is needed to evaluate policies and processes that schools, school boards, and student transportation service providers use to ensure accessible transportation for disabled students.

The transitional process from “space” to the more complex “place”, through human-assigned locational significance, has garnered significant interest in various disciplines including psychology (e.g. place attachment, place identity), urban planning (e.g. new urbanism, placemaking), and transport (e.g. transit-oriented development, complete street). This interest has yielded valuable yet fragmented insights and definitional inconsistencies in place-based terminologies resulting in perceived disorganisation of the literature and hindrance to transdisciplinary scholarship. This study aims to bring these disciplinary scholarships into a unified conceptual framework to foster interdisciplinary discourse, understanding, and collaboration. Based on a scoping review of 194 journal articles and conference papers, 13 books, and 2 reports, the study found that places are studied from the perspective of “interpreters”, “shapers”, and “connecters”. The place-based vocabularies and methodologies as used within each of these perspectives are synthesised, defined, and framed to enable cross-disciplinary discourse. The framework outlines the strength of interlinkages among the three perspectives, with shapers serving as an intermediary between interpreters and connecters, borrowing concepts and methods from both ends of the spectrum (e.g. subjective vs. objective analysis of places). Significant gaps in research among the linkages are presented, paving the way for future collaboration and understanding of places in the context of transport research.

This article aims to assess how well the economic impact of transport infrastructure is understood. Analyses of large samples of individual investment projects based on data in the so-called Flyvbjerg database have documented systematic construction cost overruns and first-year traffic demand shortfalls. They have interpreted these findings as being indicative of negative social welfare consequences of typical transport infrastructure investment projects, but that interpretation has been challenged on methodological grounds. The evidence base of ex post social cost–benefit analyses is growing and it, too, has challenged the suggestion that transport infrastructure projects destroy social welfare. Overall, it seems fair to conclude that our understanding of the project-level social welfare consequences of transport infrastructure is improving but remains far from conclusive. In contrast, aggregate-level quantitative meta-analyses provide robust results of a significant and positive relationship between transport infrastructure and economic activity at the level of regions or countries, especially in the long run and at higher levels of geographical aggregation. These aggregate-level results imply that project-level analyses should indeed consider the entire life cycle of projects, not just construction and the first year of operation, and that they should also acknowledge the presence of network effects as well as wider economic impacts – as difficult to measure and controversial as they are.

Background
Identification of priority interventions to support modal shift to walking and bike riding is challenged by the myriad of interventions available, and a lack of synthesised evidence for what types of interventions are most effective. With increasing investments in active travel, there is substantial demand for synthesised evidence of efficacy between intervention types. This systematic review aimed to measure the effectiveness of interventions to increase active travel with a primary outcome of modal shift.
Methods
The electronic databases MEDLINE, PsycINFO and Web of Science were searched. Eligible study designs included randomised and non-randomised studies of interventions with specific study design features that enabled the estimation of causality with minimal risk of bias. Studies were categorised by intervention types described within the Behaviour Change Wheel.
Results
106 studies that assessed the impact of an intervention on walking, cycling or active transport overall were included. Findings demonstrate that physical environmental restructure interventions, such as protected bike lanes and traffic calming infrastructure, were most effective in increasing cycling duration (OR = 1.70, 95% CI 1.20–2.22). Other intervention types, including individually tailored behavioural programmes, and provision of e-bikes, were also effective (OR = 1.33, 95% CI 1.23–1.43, OR = 1.13, 95% CI 1.02–1.22). An intensive education programme intervention demonstrated the greatest impact on walking (OR = 1.96, 95% CI 1.68–2.21). This body of research would benefit from more rigors in study design to limit lower quality evidence with the potential for bias.
Conclusion
This review provides evidence for investment in high-quality active transport infrastructure, such as protected bike lanes, to improve cycling and active transport participation overall. It also provides evidence for investment in other non-infrastructure interventions. Active transport research needs to move towards trials with consistent outcome measures to inform which combinations of interventions (including disincentives) are most effective.

Research in experimental psychology has contributed to the understanding of safe and effective transport. Analysing the perceptual-motor skills that support safely riding a vehicle and navigating the traffic environment has practical implications for improving educational programs, transport policies, and infrastructure and vehicle design. First, our critical review presents the state of art on experimental studies examining perceptual-motor skills in cycling. Experimental studies have often used cycling simulators or virtual reality lab settings leading to circumstances where perception and cognition are measured independent of action. Other experimental studies have examined perceptual-motor skills for controlling a vehicle but rarely used in-situ settings that sample real traffic contexts. Last, experimental studies have often investigated how individuals perform and behave to achieve the task-goal without considering the individual constraints, notably dynamic perception of body size and the action capabilities of the participants. Instead, we argue that current research would benefit from viewing cycling as a person-plus-object system, emphasising the mutual and reciprocal couplings between the individual, the vehicle and the environment. Anchored in ecological psychology, our review explores how an affordance-based control approach brings a novel perspective to study cycling by addressing how individuals attune to relevant information for action, grounded in and scaled to their action capabilities, and perceiving the opportunities for action offered by the environment (defined as “affordances”) to navigate dynamic traffic safely and effectively.

Increasing uptake of public transport as part of a sustainable transportation future requires improving people’s experience and perception of personal safety and security. People with marginalised identities like LGBTQI+ are more likely to be targets of harassment and other forms of violence, including when using public transport. This paper provides a systematic literature review on the security experiences of LGBTQI+ public transport users and practice-ready recommendations for addressing LGBTQI-directed violence on public transport. Search criteria included security/safety, LGBTQI+, and public transport. The resulting 51 publications provide key findings across five themes, starting with a foundational understanding of LGBTQI-directed violence in public transport settings. Public transport characteristics provide additional context for LGBTQI+ people’s risk of violence. LGBTQI+ people’s perceptions of personal security and fear of violence inform the discussion of consequences to LGBTQI+ wellbeing and effects on mobility. Current practices and knowledge gaps help frame how public transport researchers and practitioners can create a more inclusive planning and design process for public transport operations that are safer and more secure for all users. In doing so, public transport becomes a key vehicle for challenging – rather than perpetuating – societal normalisation of violence.

In the face of the challenge of a transformation of urban mobility, experimental approaches have seen a rise: Tactical urbanism, open streets, pop–up bike lanes, and superblocks have spread globally, and under the term street experiments, an expansive body of literature has emerged. This debate is based on the notion that experiments have a transformative capacity to provide an impetus for wider change. However, the understanding of this is still limited and forms only a tacit background in most articles. This systematic review therefore analyses the implicit and explicit theories of change that underpin the literature on street experiments. From a qualitative content analysis of 62 papers, it distinguishes four perspectives: the local implementation, innovation, citizens, and critical perspective. It also identifies the theoretical frameworks and components used to analyse or conceptualise the pathways from street experiments to transformation, finding a wide range from comprehensive frameworks – such as the multi–level perspective – to smaller, inductive components. However, their added value is partially limited because they are not sufficiently empirically grounded or conceptually adapted to the specificities of street experiments. The paper concludes that to construct more robust theories of change, there is a need to use available theory to conceptualise key impact mechanisms such as “learning” or “acceptance”, inductively connect abstract theoretical models with the complex reality of street experiments, and empirically assess assumptions.

Forecasting is vital in shipping economics and directly affects the business decisions of shipping companies and the quality development of the shipping markets. This study critically reviews variables, methods, and results used for shipping economic forecasting. This study provides an extensive review of the development of the shipping market forecasting models, which can be broadly categorised into artificial intelligence and classical economic models. Our review identifies forecasting applications in the following areas: freight markets, newbuilding and second-hand ship markets, and ship-demolition markets. We review the evolution of the forecasting methods over time and distinguish six types of feature engineering (i.e. the process of preparing and transforming input data) that improve model generalisation performance (i.e. ability for the model to work outside training data) in the existing literature. We further discuss the improvement, input determination, evaluation metrics, and hyper-parameter optimisation of models. Our analysis shows that support vector regression and artificial neural networks are the commonly used techniques; Grid search and evolutionary optimisation are popular for hyperparameter optimisation in current research. Finally, we discuss the achievements and limitations of the existing literature. The survey concludes with the identification of existing gaps and recommendations for future research.

Travel time use – also called “travel-based multitasking” – has been increasingly recognised as an important component of activity-travel behaviour, influencing time-use and travel-related choices. This paper discusses a taxonomy issue in the literature and is the first to provide a systematic and comprehensive overview of the state of knowledge on the effects of travel time use on different dimensions of activity-travel behaviour, namely, time-use, mode choice, value of travel time savings, travel experience, and second-order effects. Regarding the taxonomy issue, we conceptualise when it is suitable to employ the terms “travel time use” and “(travel-based) multitasking”. Particularly, we suggest employing “travel time use” as the overarching term to refer to the act of undertaking activities while travelling, while “(travel-based) multitasking” is regarded as special case of travel time use when two or more cognitively/physically demanding tasks overlap. Regarding the knowledge consolidation, considering current and future transport options, we conduct a meta-synthesis to identify prevailing hypotheses about the effects of travel time use on activity-travel behaviour and then review empirical studies to examine the extent to which the current knowledge corroborates predominant hypotheses. Considering these findings, we discuss a research agenda to appraise the effects of travel time use on activity-travel behaviour.

Ridesourcing has received significant attention globally due to its rapid expansion. As it has been more than a decade since the first ridesourcing operation, there is a growing interest in its long-term impacts, in particular on vehicle ownership, which is a key factor behind car use and various traffic-related and environmental externalities. The two-sided business model of ridesourcing positions both drivers and passengers as customers of these platforms, making the net impact a function of effects on both groups. This systematic literature review explores the relationship between ridesourcing and vehicle ownership from both perspectives. Utilising the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, this review analyses 31 peer-reviewed articles and three reports to evaluate these impacts. The findings reveal a general negative association between the use of ridesourcing and the number of vehicles in the household, though the causality of this relationship remains unclear. Notably, while a stated reluctance to purchase cars exists among individuals in the presence of ridesourcing, in most cases in developing countries the "value enhancement effect” (the incentive for ridesourcing drivers to acquire new vehicles) has dominated the “substitution effect” (the reduction in car purchases among ridesourcing customers), leading to an increase in vehicle ownership, whereas developed countries exhibit mixed outcomes. The review thus highlights the heterogeneous relationship between ridesourcing and vehicle ownership across different countries and regions, varying with many factors including levels of development and urbanisation. Additionally, the study identifies gaps in existing knowledge and proposes directions for further research on the impacts of ridesourcing.
