The dry bulk shipping market is highly competitive, with many small-scale ship owners engaging in short-term contracts. However, ship owners often find it challenging to acquire new fixtures after each voyage, and there is a risk of wasting time and cost on looking for a new fixture. This study aims to explore how to improve the use of vessels in the dry bulk spot market by avoiding the risk of wasting time. We construct a database to explore where and when vessels get new fixtures during their voyage by combining the automatic identification system and fixture data. The data shows ships without new fixtures during a previous laden voyage spent more time ballasting than those with new fixtures. For ships without new fixtures during a previous laden voyage, we confirm that the elapsed time from discharge and sailing distance to loading areas are critical for vessels in selecting their next destinations by developing a multinomial logit model. A simple simulation of sailing at different speeds from different discharging ports shows potential strategies, such as vessel speed and direction of the navigation, to improve the probability of getting a new fixture.

In the context of sustainable logistics, innovative approaches are imperative, with intermodal transport being recognised as a pivotal solution for mitigating environmental impact and enhancing efficiency. This study analyses the dynamic interaction between diesel, LNG and electric trucks in direct transport as well as in the pre- and on-carriage segments of intermodal transport chains. Utilising a discrete-event simulation model founded upon genuine operating data derived from an Austrian forestry enterprise, this study undertakes a comprehensive investigation into the ecological and economic ramifications of alternative drive systems. The findings indicate that LNG lorries emerge as a particularly cost-effective solution, while electric lorries demonstrate the lowest greenhouse gas emissions. However, the findings also highlight the impact of limitations in charging infrastructure and high energy costs on the efficiency of these vehicles. Diesel lorries offer a balanced middle ground but cannot dominate in either category.
The study emphasises the transformative potential of alternative fuel technologies in multimodal systems and provides a basis for decision-making for the sustainable design of logistics chains. The study underscores the significance of a diversified fleet strategy to achieve environmental and economic objectives, particularly in the context of the European climate targets for 2030 and 2050.

Errand delivery as an emerging delivery method, has experienced rapid expansion during and after the pandemic. Enterprise users play a pivotal role in the success of errand delivery, serving as the recipients and participants in the service. This study constructed a new theoretical framework based on a second-order structural equation model that integrates the perceived SERVQUAL model within the TOE-TAM model. It investigates how the service quality of this emerging delivery method influences the perceptions of enterprise users and subsequently impacts their intention of errand delivery(INED). The findings indicate that technological, organizational, and environmental factors of errand delivery, grounded in an expanded perception of service quality, significantly influence user perceptions, subsequently affecting their INED. In particular, technology plays a pivotal role in this influence. Additionally, perceived usefulness and perceived ease of use serve as intermediaries between TOE and INED. In summary, this study comprehensively explains the motivational factors behind errand delivery. Further, this research offers managerial insights for errand delivery companies and platforms, as well as relevant industry professionals, to help them attract enterprise users, enhance satisfaction, and prepare for competition within the crowdsourced delivery sector.

The growing literature on the critical success factors (CSFs) of the public-private partnership (PPP) projects mostly focus on one or a couple countries generally from several Asian economies or developed countries. This study, on the other hand, analyzes a large sample of Islamic countries (many of which remained untouched before) from Middle East and North Africa, Sub-Saharan Africa, and Asia. Based on a sample of 36 transport experts working in the government from 25 Islamic countries, this paper employs a questionnaire survey to evaluate how they assess the CSFs in the transport PPP projects. According to the responses to the questionnaires, financial strength of the private partner, political support, political stability, effective monitoring of the private partner, and favorable legal framework are the top five CSFs. In addition, our complementary factor analysis groups 18 CSFs into five factor groupings such as (i) transparent and competitive bidding, (ii) financial strength and stability, (iii) effective relationships between public and private parties, (iv) financial markets and risk management, and (v) public and political support. The findings reported can help policy makers better design the PPP procedures, reduce the associated risks, and ensure value for money.

In 2023, Total Freight Volume of Sea-Rail Intermodal train in China reached 11.7 million TEUs, setting a historical record. However, this volume only accounts for 3 % of the total throughput at China's coastal ports, compared to 20 %–40 % in other developed countries. This indicates that there is still significant potential for development in China's sea-rail intermodal transport. This paper identifies two main reasons hindering its development. On the one hand, the conflict between railway operators and shippers leads to wasted train capacity, preventing an increase in transportation volume. On the other hand, the high cost of empty container repositioning has resulted in a shortage of empty container resources, leaving many regions without sufficient empty containers to meet transportation demand. This paper aims to integrate the transport demand for loaded and empty containers throughout the entire train journey, maximizing the effective utilization of train capacity and achieving a “Full-length and Full-occupied” strategy for the entire route. This paper optimizes train scheduling under random demand, minimizing the conflicts above while alleviating the shortage of empty containers. The study first uses Monte Carlo simulation to generate data on random demand. Then, it establishes a collaborative optimization model for loaded and empty containers to maximize the railway operators' transportation profits. Finally, Ningbo-Zhoushan Port and its hinterland are used as an empirical case to demonstrate the feasibility of this strategy. The results show that while capacity utilization increased by 10 %, profit margins also increased by 27 %, indicating that train capacity waste was controlled and more transportation demand was met.

Digital transport infrastructure (DTI) assets efficiently support people's daily activities of an economy. However, there remains limited research into examining how they impact environment. Acknowledging this gap, we identify the influence mechanisms of DTI comprising population size, economic growth and data flow under an expanded STIRPAT, and then examine them by developing the fixed- and mediation-effect econometric models. The results reveal that DTI can reduce pollution emissions at the national level within the economically developed regions, while its effect on the less developed economy is insignificant. Empirical evidence also indicates that there is an inverse relationship between the population size/data flow and air pollution, which however is aggravated by the economic growth. Moreover, the inhibitory effects of the population size and data flow on environmental emissions was positively changing (i.e., from insignificant to significant) during the period of 2006–2021. This research sets forth a platform to rethink the implications of environmental policies for DTI development within the long-term context.

In recent years, innovative city logistic concepts for courier, express, and parcel (CEP) shipments have raised particular interest in contributing to a more sustainable transportation system. One solution can be the utilization of existing urban rail infrastructure. A so-called ‘cargo tram’ transports goods to an intermodal city hub, where cargo bikes cover the last leg to the receiver. Although conceptional or economic studies exist, detailed analyses of the transport-related effects, e.g., through freight demand models, still need to be carried out. Hence, in this study, we develop a methodology to integrate urban rail-based parcel transport in terms of a cargo tram into the existing agent-based freight, i.e., parcel, demand model logiTopp. Instead of a single mode choice, a two-stage selection model based on transport chains is developed, comprising a rule-based and utility-based stage. The proposed methodology is implemented in logiTopp, and the model is applied to the city of Karlsruhe, Germany, where the overall effects of rail-based parcel transport are simulated and evaluated in proof-of-concept scenarios. The analysis shows that the proposed transport chain selection model produces overall reasonable results. Moreover, they indicate that the realization of a rail-based parcel transport can reduce the overall mileage and number of trips caused by CEP shipments. However, the potential is driven by several factors, such as the number and location of city hubs, the maximum range of cargo bikes, and the overall evaluation of the cargo tram. Additional empirical investigations are necessary to validate the results from the proof-of-concept scenarios.

Air transportation is undergoing a transformative phase with emerging technologies that are expected to revolutionize the industry. This paper employs artificial intelligence (AI) to conduct a comparative SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis of key emerging technologies within the domain of air transportation. The technologies under consideration are urban air mobility (UAM), unmanned aerial vehicles (UAVs), electric aircraft, supersonic aircraft, and sustainable aviation fuels (SAFs). Automated SWOT analysis holds the potential to release cognitive resources for more challenging tasks and mitigate subjectivity—a commonly raised critique regarding traditional SWOT analysis. It turns out that AI-generated SWOT analysis yields meaningful content, which should be of interest for industry stakeholders concerned with the future course of air transportation. The paper also discusses the limitations of this approach.

Developing a robust reporting culture is essential in aviation as it facilitates proactive accident prevention. Although pilots' attitudes towards incident reporting have attracted international research interest, similar research in Greece—a member state of ICAO and EASA—remains very limited, leaving the operational, regulatory, and cultural factors influencing Greek pilots' reporting practices largely unexplored. This research utilized qualitative methods, including semi-structured interviews (N = 18) with military, commercial and general aviation pilots operating in Greece, to explore their views and attitudes towards incident reporting. A detailed representation of the participants' views was facilitated through Thematic Analysis and certain characteristics of Content analysis based on their narratives. The findings of this study aligned with previous research as fear of blame, stigmatization and career progression concerns were among the most substantial barriers to incident reporting, emphasizing that the under-reporting issue persists. Novel insights included the tendency of participants deriving from the commercial sector to be more willing to report safety events, as a result of their aircraft being fitted with a flight data monitoring device. Additionally, participants viewed high reporting frequency as a practice that could draw organizational attention to them and was therefore perceived as a deterrent. Differences between military, commercial and general aviation participants were minimal, indicating a common attitude towards reporting in all three sectors. Recommendations from participants emphasized fostering a just culture over a blame-centric one, advocating for a trustworthy reporting system where fear of punishment does not deter reporting, and where valuable outcomes are shared to boost motivation and strengthen their reporting culture. It is envisaged that enhanced safety-related education should be fostered among pilots, managers and top executive leadership with special focus on the value of incident reporting so as to maximize the benefits of such systems and minimize under-reporting.

The rapid expansion of China's high-speed rail (HSR) network has substantially reduced intercity travel time. However, few studies have examined door-to-door HSR accessibility and disparities for different parts of HSR journeys within major metropolitan areas. Using train timetables and intracity transport data, this study analyzes the disparities in HSR accessibility in the Yangtze River Delta (YRD). HSR accessibility patterns for cities of different levels are further analyzed for passengers using private or public transportation to connect with HSR stations. These findings highlight disparities in HSR accessibility across cities. Time spent on intracity travel constitutes a significant portion of the entire journey and it accounts for up to half of the total travel time when using public transportation. Cities of a higher administrative level tend to have a relatively larger percentage of their total travel time on intracity travel, which diminishes the overall efficiency of intercity HSR services. In county-level cities, substantial inequality in private and public transport connections is found. This study underlines the significance of inner-city transport connections to HSR stations and the provision of public transport services. It also enriches HSR accessibility studies by considering diverse components of door-to-door travel.
