This paper presents the results of a scoping review concerning the state of knowledge with respect to the impacts of COVID-19 on daily personal travel in the Global South. Based on the available literature in the Global South, the paper aims to: (1) provide an overview of the current state of knowledge regarding the personal daily travel of different socio-economic and demographic groups during COVID-19; (2) synthesise the literature to explore the needs of the different socio-economic and demographic groups; and (3) identify groups who received less attention in transportation research in the Global South so far. The paper reviewed 47 studies and found that while investigating personal travel during COVID-19, the most explored socio-economic and demographic attributes were sex, age, income, occupation and educational qualifications. Some regional differences were evident in terms of mode choice during COVID-19. Through the review, it is also noticeable that none of the studies explored LGBTQ+ communities’ and individuals with disabilities’ transportation needs and challenges and how COVID-19 has impacted their personal travel. Other overlooked socio-economic and demographic groups in the Global South whose personal travel during COVID-19 and the post-pandemic period needs investigation are migrant and seasonal workers, children and youths, ethnic minorities, racial minorities, religious minorities, linguistically diverse individuals, indigenous individuals, and individuals residing in rural areas.

Maritime autonomous surface ships (MASS) are transforming the future of maritime transport. They are expected to shoulder important roles in seaborne trade and maritime resilience. As the primary operator of traditional ships and a significant component of maritime transport, seafarers are inevitably directly and indirectly affected by levels of automation introduced into the shipping space. Therefore, in addition to increasing attention to automated system designs, a holistic understanding of human elements in MASS operations is necessary. The current research (1) reviews human-centred MASS research, (2) categorises MASS impacts on seafarers, and (3) summarises responses to prepare seafarers for this emerging technology. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, a total of 101 articles were collected from Scopus. The systematic review reveals that MASS impacts seafarers from the following dimensions: employment, task contents, requisite skills, and human risks. Moreover, regulations and education frameworks can be adapted to respond to changes in seafarer demand and supply. Future research directions are also proposed and can serve as recommendations for future human-centred research on MASS. The research findings enhance the understanding of seafarer elements in MASS operations and provide policy implications for future seafarer management.

Public transport service reliability is crucial for all stakeholders, including users, operators, and society. Bus bunching, where two or more buses on the same route travel closely together, significantly undermines service reliability. This paper reviews bus bunching, its causes and consequences, and control strategies from demand, supply, and decision-making perspectives. It identifies gaps in the literature, emphasising the need for realistic evaluations of control methods and real-world applications. The paper reveals that most bunching solutions prioritise operators over public transport users, and the trade-offs posed by these methods require further examinations. Hybrid methods combining holding with other measures have outperformed standalone holding methods but need real-world testing. User-centric approaches, such as encouraging and incentivising passengers to choose less crowded vehicles or wait, have demonstrated some potential in alleviating service bunching. However, their effectiveness in real-world applications present important research directions. In summary, the practical classification and framework presented in this review can assist policymakers in making informed and optimised decisions by considering various variables and performance measures involved in the process, and in finding balanced solutions for passenger and operator.

Parking in dense urban areas is a major challenge for last mile logistics. Parking shortage and policies that do not address commercial vehicles’ needs often lead these vehicles to park illegally. This paper conducts a scoping literature review on the parking behaviours of commercial freight and service vehicles, methods used to model these behaviours, and factors that determine their outcomes. Thirty-four studies are included in the review. It is found that commercial vehicles’ parking behaviours mainly comprise parking location and type choices including illegal parking, parking duration, and parking cruising. Methods used to model these behaviours primarily include discrete-choice modelling, regression analysis, survival analysis and simulation. We identify key knowledge gaps and provide insights on research opportunities in modelling more complex parking decisions, investigating parking cruising of commercial vehicles, evaluating the implications of freight demand management, and developing data fusion techniques.

A variety of shared mobility hubs, offering shared mobility and other services, have emerged in many cities across the globe. This paper provides a literature review on of the definition and categorisation of shared mobility hubs, guidance for the design of these hubs, and develops a multidimensional typology for shared mobility hubs. The typology, named the SmartHubs Integration Ladder, is based on three integration dimensions: physical, digital, and democratic. The literature review shows that digital and democratic (participation) integration dimensions, and universal design principles are typically missing in shared mobility hub concepts, definitions and planning practice. This implies that existing shared mobility hubs will not reach their full potential in terms of user and societal value. The “smarter” shared mobility hubs are physically, digitally, and democratically, the more user and societal value can potentially be created.

With the spread of smartphones and mobile internet, Global Positioning System (GPS) data from vehicles has become widely available. This data represents a unique opportunity to automatically extract road network features and generate detailed maps that can be used in the creation of transport network models, while minimising the quantity of resources usually invested in that task. Accurate transport network models can be used in a variety of applications either in transport simulation models or autonomous vehicles navigation. Although two relevant literature reviews were performed during the last decade, they were not systematic and did not explore the road network inference methods from a transport network modelling point of view. The objective of this research is to perform a systematic and reproducible literature review on the use GPS data in transport network modelling and provide limitations and future work to extract a road network representation for transport models and autonomous vehicles navigation. This was done by systematically examining the studies’ different approaches with respect to relevant criteria. Most studies produced a simple representation of the road network, not detailed enough for transport models. Other limitations were the bias introduced by the GPS sample and the reproducibility of the different methods.

This study is a review of the existing literature on the topic of bike-transit combination. The aim is two-fold: (i) to identify factors that influence its successful uptake, and (ii) to discuss the potential of the bike-transit combination and its impact on urban transport systems. The review showed that the bike-transit integration is complex and can be influenced by a variety of factors. These factors are mainly related to the quality of public transport, the cycling network and the integration of these two. Improving them can have a positive impact on bike-transit uptake. Land use and built environment characteristics also play an important role, suggesting that the local context plays a significant role on its successful uptake. In general, the review reveals that bike-transit has shown potential in improving the performance of existing public transport systems, by expanding catchment areas and improving accessibility, but its impacts on car use have not been explicitly studied. The review concludes that the bike-transit combination shows a promising path to sustainable urban mobility and is a topic worth further investigation. However, it also calls for more integrated research approaches and an explicit focus on which types of travel behaviour are substituted by the bike-transit combination.

Although many barriers remain to the employment of people with disabilities, public transportation can play a key role for integration and retention of people with disabilities in employment. However, research is needed to better understand how public transportation influences access to work for people with disabilities. This study aims to identify public transportation-related barriers and facilitators to the employment of people living with disabilities. A scoping review approach was adopted, with a keyword search through six databases. Studies’ characteristics, transportation barriers, and facilitators to employment of people with disabilities were extracted from the selected articles. The results were presented descriptively and narratively. In total, 74 studies were included. Barriers and facilitators were grouped under four themes: (1) public transportation, (2) employment, (3) personal factors, and (4) social network. This review highlights the key role of public transportation in accessing and maintaining employment for people with disabilities. It also reveals gaps in the literature and a need to investigate the issue through the lens of employers, public transportation services, and social environmental facilitators.

Our societies struggle to provide a good life for all without overconsuming environmental resources. Consequently, scholarly search for approaches to meet environmental and social goals of sustainability have become popular. In transport research, accessibility is a key tool to characterise linkages between people, transport, and land use. In the current paper, we propose a conceptual framework for measuring just accessibility within planetary boundaries. We reviewed transport studies and discovered a substantial literature body on accessibility and social disadvantage, much vaster compared to the literature around environmental and ecological impacts of accessibility. We also show a gap in approaches that have integrated these two perspectives. Building on the review, we suggest a conceptual framework for incorporating environmental and social sustainability goals in accessibility research. We conclude the paper by pointing to key challenges and research avenues related to the framework, including (i) dealing with uncertainty and complexity in socio-ecological thresholds, (ii) integrating environmental limits into the conceptualisations of transport equity, (iii) measuring accessibility through other costs than travel time, and (iv) integrating both quantitative and qualitative data.

Urban freight systems embed and reflect spatial inequities in cities and imbalanced power structures within transport decision-making. These concerns are principal domains of “transportation justice” (TJ) and “mobility justice” (MJ) scholarship that have emerged in the past decade. However, little research exists situating urban freight within these prevailing frameworks, which leaves urban freight research on socio-environmental equity and justice ill-defined, especially compared to passenger or personal mobility discussions. Through the lens that derives from TJ and MJ’s critical dialogue, this study synthesises urban freight literature’s engagement with equity and justice. Namely, the review evaluates: How do researchers identify equitable distributions of urban freight’s costs and benefits? At what scale do researchers evaluate urban freight inequities? And who does research consider entitled to urban freight equity and how are they involved in urban freight governance? The findings help inform researchers who seek to reimagine urban freight management strategies within broader equity and justice discourse.
