University campuses represent important transport attraction poles in cities due to the large number of students, faculty and administrative staff who commute to the campus daily. The campus location can significantly increase traffic around the area, especially during the class entry and exit times. Therefore, public transport systems are essential to facilitate access to the university campus worldwide, especially for students. This study aims to evaluate the level of importance and satisfaction with factors that affect public transport use among university students. In this context, a best-worst scaling experimental design is used to carry out an important performance analysis (IPA) of public transport services to university campuses in Gran Canaria by estimating a Mixed Logit model. Thus, it will be possible to determine what attributes should be prioritised when implementing policies for improving these services. The results showed that public transport managers and university authorities should primarily focus on providing direct services and improving punctuality and bus frequency. Our results also provide valuable insights into the search for the best policies that match students’ transport mobility preferences with the service provision.

To regulate the dividend behavior of listed companies, it is essential to identify the dominant factors influencing dividend policies. The introduction of high-speed rail (HSR) in cities can enhance market accessibility, generating competition, growth and governance effects, thus providing an opportunity to address this issue. Using a sample of Chinese A-share listed companies, this study finds that list companies' cash dividend levels significantly decrease after the introduction of HSR in a city. This indicates that capital needs, rather than agency problems, are the dominant factor influencing the company's dividend policy. And the capital needs originate from competition effects rather than growth effects. Furthermore, this paper rules out potential interference from financing environment and governance effects. The findings support the capital needs hypothesis induced by competition effects and offer insights for regulating dividend policies of listed companies, promoting long-term stable and healthy development of the capital market.

The strategic positioning of warehouses is fundamental for mitigating urban freight transport challenges and advancing Sustainable Development Goals (SDGs), influencing both the volume and efficiency of freight movements. This study explores the relationship between spatial accessibility and warehouse location decisions, emphasising the integration of accessibility metrics in urban planning. By applying Exploratory Factor Analysis (EFA), we developed a comprehensive accessibility indicator that incorporates transportation infrastructure, land use patterns, temporal constraints, and individual stakeholder needs. Using Fortaleza, Brazil, as a case study, we assessed the spatial distribution of this indicator and its correlation with the density of large warehouses established. Our findings indicate a significant spatial relationship between high accessibility zones and warehouse locations, highlighting the indicator's effectiveness in guiding logistical operations and urban policy. The research underscores the importance of accessibility in fostering sustainable and equitable urban development, offering valuable insights for both public authorities and private logistics sectors in optimizing urban freight distribution.

This review employed network analysis to systematically examine 92 journal articles supported by VOSviewer, with the goal of bibliographically analysing and identifying the external researched themes influencing the development of low-cost carriers in the Asia-Pacific region. The analysis revealed that the development of LCCs in the Asia-Pacific region is predominantly influenced by 54 researched themes, categorised under 12 major themes. Among these themes, the most extensively researched were “aviation-related regulations, policies, and laws”, “airports' infrastructure, capacity, and operations”, “market conditions”, “passenger factors”, and “competitive aviation market”. Furthermore, this study proposed potential research directions and areas to guide future academic investigations and inform policy and decision-making with respect to the LCCs’ future development and operations.

This paper reveals the mechanism of how different personal variables interactively impact the purchasing behaviors for automated vehicles (AVs). Data is collected from a state-wide public survey study. The structural equation model-based path analysis is employed to reveal the variables' interrelationship. A hierarchical model is used to quantitatively understand the willingness to pay extra money for different automations levels. The revealed internal relationships between variables facilitate understanding why the variables impact an individual's purchasing behavior. The results show that rural residents are less likely to purchase an AV due to their lower income and familiarity levels compared to urban residents. Highly educated individuals who drive more frequently are more likely to pay for an AV because they demonstrate a higher ability to afford one. Safety concerns remain the primary factor influencing purchasing behavior. This study contributes to the literature by revealing internal heterogeneity and the psychological effects that influence purchasing behaviors for AVs, as well as the willingness to pay extra for each level of automation. The results are expected to be beneficial for government policymakers, vehicle manufacturers, and organizational stakeholders in devising long-term policies.

This study aims to evaluate passengers’ valuations of occupancy levels and public transport policy options during the COVID-pandemic. An important objective of the research is to understand how passengers value uncertainty in the occupancy level for their trip.

We estimate a mixed logit model, using stated choice experiments among 195 respondents. One of the features of the stated choice experiments is a simple representation of probabilities for different occupancy levels.

Our results suggest that the highest occupancy level dominates passengers’ choices, regardless of probability. This implies that respondents have a strong aversion to high occupancy rates, even at low probabilities. In terms of policy options, we find that respondents value blocked seats positively, which is consistent with the aversion to high occupancy rates. The obligation to wear face masks and reserving seats for travelers in vital professions are also valued positively.

Blocked seats, obligatory face masks and reserving seats for vital professions are viable policy instruments in a future pandemic. Moreover, the strong aversion to high occupancy rates may also be relevant for public transport policy in times without pandemic. Further research could be aimed at testing the relevance and order of magnitude of this finding in the post-COVID era.

In the situation of the COVID-19 pandemic, the intercity railway sector faces significant challenges related to service quality and gender equity. This research aimed to explore the differences in service quality perceptions between male and female passengers, examining how these perceptions influence their intentions to use intercity rail transportation. Employing Structural Equation Modeling, the study analyzed responses from 1593 passengers across four major regions of Thailand, utilizing a comprehensive questionnaire that assessed factors such as Service Quality and Health Motivation. The findings revealed that female passengers place a higher emphasis on service quality, particularly concerning safety and cleanliness, which significantly impacts their travel intentions, while male passengers focus on safety and infrastructure. Moreover, health motivation emerged as a crucial factor influencing female passengers' decisions to use railway services, especially in the context of the ongoing pandemic. The study recommends implementing enhanced safety measures, improving communication about service changes and safety protocols, and offering flexible pricing models to address the distinct needs of male and female passengers. These policy recommendations aim to promote gender equity and improve overall passenger satisfaction in the intercity railway sector, contributing to a more inclusive and responsive transportation system in the post-pandemic era.

We propose a new theoretical autonomous vehicle (AV) acceptance model and use pre-post data to predict acceptance intention changes in the post-pandemic era. Based on the Technology Acceptance Model (TAM), this paper further incorporated trust, perceived risk, social influence, and perceived COVID-19 risk into the original TAM to explore the public acceptance of AVs. Moreover, combining the structural equation model and ordered logit model, this paper adopted a hybrid choice model including psychological attributes, socio-demographic attributes, travel attributes as well as ethics, legal responsibilities, and vehicle safety levels to clarify determinants of the public AV acceptance changes before and after the pandemic. This study solicited 466 residents in China, and used online surveys to collect stated preference data. The results show that the significant positive impact of COVID-19 on the changes in acceptance of AVs for people's mobility, especially for the higher automation levels. It makes AVs more appealing after COVID-19 outbreak. In addition, perceived usefulness, perceived ease of use, trust, and social influence also have a significant positive impact on the public AV acceptance changes. Gender, age, dedicated lanes, government subsidies, traffic accident experience, travel mode, travel expense, and other factors are related to AV acceptance changes as well. We provide insights for measuring the changes in acceptance of AVs across time due to public health emergencies.

To investigate the environmental implications of a collaborative approach between fixed-route transit and demand-responsive transit, this paper studies a bimodal hierarchical transit system, with a specific focus on the impact of CO₂ emissions. In this system, demand-responsive transit serves regions with lower demand, while fixed-route transit extends its service to the central business district. Subsequently, a continuous approximation model is formulated, optimizing critical network design parameters such as stop spacing, line spacing, and headway. This optimization process balances passengers' time costs, agency expenditures, and environmental considerations. A series of comparative analyses are conducted to assess the influence of incorporating emission-related costs into the network design. The inclusion of environmental factors in the design process results in an approximate 8.3% reduction in CO₂ emissions. Furthermore, numerical case studies are presented, encompassing a broader spectrum of key design parameters, including the value of time and variations in demand. The findings also demonstrate that the proposed hierarchical transit system exhibits lower CO₂ emissions when compared to the paired-line system.

Governments support the switch to electric vehicles (EVs) through subsidies and other incentives, as this is expected to help meet climate targets. This research examines the affordability of EVs for Irish households, focusing on equity implications and the impact of affordability on achieving decarbonisation goals. Affordability is estimated for eight scenarios, considering both current and reduced EV prices, and assessed across Ireland. The research finds that flat-rate subsidies do not adequately support lower-income households, impede EV adoption, and could jeopardise the achievement of emission reduction targets. Need-based subsidies would ensure more inclusive EV uptake. If current prices are considered, the target for the number of EVs on the road by 2030 can be met only with the purchase of small-sized EVs. This suggests that achieving EV targets is unlikely without promoting smaller vehicles. The current €3500 EV grant may be insufficient for many households without extended loan terms. Therefore, differentiated subsidies based on income and household size are recommended to increase EV adoption. Households in remote rural areas, where forced car ownership is high, require higher subsidies. In contrast, urban areas could receive lower subsidies to promote the use of more sustainable transport modes, such as cycling, shared mobility, and public transport.
