Air transportation is a mode of transport developed specifically to provide access to long-distance destinations that may otherwise be infeasible or at least more difficult to reach. Accordingly, there are distinct aspects of air travel that require consideration when assessing accessibility by air transportation, which are not addressed in general local accessibility studies. This paper reviews studies of accessibility by air transportation. The studies in question were published in academic journals, and we analysed them using the broad theoretical framework of accessibility of Geurs and van Wee [Accessibility evaluation of land-use and transport strategies: Review and research directions. Journal of Transport Geography, 12(2), 127–140]. We discuss the characteristics of accessibility by air transportation to consider when designing research, as well as trends and knowledge gaps in the existing literature. An important gap is that, while there is a growing interest towards perceived accessibility by air transportation, accessibility measures based on this perspective have not yet been applied yet. Additionally, the literature is largely focused on the transport and land-use components of accessibility as opposed to the individual and temporal components. We finish by discussing the benefits and drawbacks of directly applying conventional accessibility measures for research on accessibility by air transportation, as well as options to modify the temporal component of conventional person-based accessibility measures for better applicability in the air travel context.

The level of greenhouse gas emissions is one of the most important issues today, both professionally and politically, because a lower level of greenhouse gas emission is mandatory for a sustainable economy. Besides industry and households, the transport sector is also responsible for these emissions. For this reason, it may be essential to set up a model with which the amount of CO2 emissions could be estimated or predicted. This article presents a model that examines the extent of economic development and CO2 emissions in European countries. The result is establishing a pattern requiring a longer time series. If the pattern is proven, a clear reassessment of the current relationship between economic development and environmental protection should be made.

This paper positions possibilities for human geographies of the sea. The growing volume of work under this banner has been largely qualitative in its approach, reflecting, in turn, the questions posed by oceanic scholars. These questions necessitate corresponding methods. Whilst this is not necessarily a problem, and the current corpus of work has offered many significant contributions, in making sense of the human dimensions of maritime worlds, other questions --and methods--may generate knowledge that is useful within this remit of work. This paper considers the place of quantitative approaches in posing lines of enquiry about shipping, one of the prominent areas of concern under the banner of 'human geographies of the seas'. There is longstanding work in transport geographies concerned with shipping, logistics, freight movement and global connections, which embraces quantitative methods which could be bridged to ask fresh questions about oceanic spatial phenomena past and present. This paper reviews the state of the art of human geographies of the sea and transport geographies and navigates how the former field may be stimulated by some of the interests of the latter and a broader range of questions about society-sea-space relations. The paper focuses on Automatic Identification Systems (or AIS) as a potentially useful tool for connecting debates, and deepening spatial understandings of the seas and shipping beyond current scholarship. To advance the argument the example of shipping layups is used to illustrate or rather, position, the point. [ABSTRACT FROM AUTHOR]

This paper contributes to the robust dialogue in animal geographies by adding a focus on mobilities. Trans-paw-tation establishes a framework for understanding animal mobilities by drawing on a range of epistemological and methodological approaches, all of which aim to better understand animals and their role in the world. It goes on to propose three approaches to trans-paw-tation and the theoretical possibilities of thinking across animal geographies and mobilities: first, by reflecting on the movement of animals and animals' movements in both the historic and contemporary city; second by examining animal policies and the ways in which animals are included and excluded from urban mobilities; and third, by considering the metaphorical and symbolic associations between animals and mobilities. These deliberations are based in South African cities where both animal and transport geographies have been exploited as a mechanism for discrimination and control, and in the postapartheid context, offer opportunities for social and spatial integration. In so doing, this paper moves beyond anthropocentric approaches to mobilities by bringing animal geographies into conversation with African and urban studies and by offering a methodological contribution towards understanding trans-paw-tation.

The article focuses on the challenge of integrating high-density housing with public transport services, examining its implementation and equity implications, particularly in Melbourne. It discusses the considerable growth in apartment housing along public transport corridors and evaluates whether public transport services have kept pace with this growth, highlighting disparities in service provision across different areas and the need for further equity assessments.

The Journal of Geographical Systems (JGS) has announced two initiatives to recognize outstanding research published in the journal. The first initiative is the JGS Best Paper Award, which aims to encourage and acknowledge excellent scholarship in the field of GIScience and spatial planning. The second initiative is the Editors' Choice, where the editors select their favorite paper from each issue. The winners of these awards are listed on the journal's website and their papers are made freely accessible for a certain period of time. The 2023 JGS Best Paper Award was given to Luyu Liu, Adam Porr, and Harvey J. Miller for their research on evaluating the reliability of public transit accessibility using real-time data. The paper demonstrates how even small levels of unreliability in transit services can significantly impact accessibility levels, particularly for lower income populations. The paper also promotes open and reproducible research practices. The Editors' Choice for Volume 26(1) is a paper by Chris Jacobs-Crisioni, Ana I. Moreno-Monroy, Mert Kompil, and Lewis Dijkstra, which proposes a sequential approach to estimate school provision, cost, and access using open databases of student counts. The paper provides valuable insights into the balance between cost, access, and residential values in school provision. Both papers are recognized for their significant contributions to the field.

Most U.S. beef packers with multiple plants now openly employ multi‐plant coordination. Using a Salop Circular City framework that includes negotiated and formula pricing, we demonstrate that multi‐plant coordination leads to wider spreads between downstream beef prices and upstream fed cattle prices if multi‐plant coordination markdowns outweigh multi‐plant coordination efficiencies. Taken together with market concentration, geography and transportation costs, and cattle cycles and related beef packer capacity utilization, multi‐plant coordination helps explain persistently wide farm‐to‐wholesale beef price spreads. We find that, as cattle inventories decline, a multi‐plant coordinator will permanently shut down a plant before the same plant run as a separate profit center will shut down, which is consistent with packer behavior in recent years. We also demonstrate that adding a strategically‐located packing plant, owned by an entrant firm, can narrow price spreads. This framework is important for ongoing policy discussions regarding the structure, conduct, and performance of the beef packing industry. [ABSTRACT FROM AUTHOR]

This paper sheds light on the understudied phenomenon of female two-wheeler riders in Bangladesh, and their everyday negotiations of moto-mobility in patriarchal public spaces. In transportation research, female riders have traditionally been characterized as occupying the pillion seat. By conducting ethnographic observations of two-wheeler training clubs in Bangladesh (Dhaka) and qualitative interviews with female riders, the paper expands the discussion of gender and mobility beyond the usual focus on car and public transport in the Global South, which is critical for planning equitable and inclusive transport policies. Using the motility framework (access, competence and appropriation), this paper unravels the cultural, spatial and social dynamics of women's everyday moto-mobility. Through engagement in women-only training clubs which also serve as gendered social spaces, female riders actively build technical and spatial competence. They opt for safety-conscious approaches in driving behaviour, subverting traditional/masculine notions of dominance and authority. The findings also reveal how young riders subvert families and communities to acquire and ride motorbikes, but still largely conform (and adapt) to social norms to manufacture respectability (following normative sartorial choices, sex-segregated seclusion/purdah). In other words, their resistance is in proportion to how much they can assert themselves without facing negative repercussions from communities and society at large. As their presence and performances of micro-subversions rewrite spatial geographies (of risk and respectability), this has implications for reshaping the everyday transport geographies of women in urban public spaces. By presenting gender scripts as an element of appropriation in the constant negotiation of mobility, this paper contextualises motility in a non-western setting, and shows how multiple (seemingly contradictory) gender performances can feed into each other and regroup to facilitate women's access (to mobility) and rights in a gendered city. • Female motorbike riders in Bangladesh negotiate patriarchal urban public spaces. • In doing so, they challenge traditional gender scripts and reconstruct new ones. • Training clubs offer women new and safe spaces for gendered sociality. • Their micro-subversions rewrite spatial geographies (of risk & respectability). • This has implications for everyday geographies of women's mobility in urban spaces.

• Actual travel distance is a stable factor in the port-hinterland relationship. • Distance-decay effect follows the exponential model instead of a power function. • The 'islands' are commonly located in the border areas between cities. Ports are pivotal in the socioeconomic development of regions, countries, and cities as they serve as gateways for the transportation of goods between sea and land. Analyses of port hinterlands can enable port authorities and shippers to develop competitive strategies while assisting local authorities in identifying areas where inland transportation systems require improvement. In general, physical distance is a robust proxy for transportation costs. However, the role of distance in the context of port regionalization remains under debate, despite the spatial interaction model, with distance decay being commonly used to analyze the port–hinterland relationship. Doubt concerning the explanatory power of distance may act as an obstacle for port managers and local authorities in assessing the market share of ports, as well as in constructing planning agendas related to facility locations. This study examines the distance decay of port hinterlands using more than 0.18 billion points of heavy-duty truck GPS trajectory data from the Guangdong–Hong Kong–Macau Greater Bay Area. We develop an algorithm to compute heavy-duty truck flows and actual travel distance between the port and identified facility areas, and we apply the weighted least squares method to evaluate the explanatory power of six distance-decay models. Our findings reveal that the actual travel distance is a significant reduction factor in the port–hinterland relationship, while it follows the exponential model instead of a power function. This paper presents new evidence to reshape the role of distance in delimiting port hinterlands, providing port managers and local authorities with novel insights into the structure of port hinterlands in the context of port regionalization.
