Mobility-as-a-Service (MaaS) promises to transform urban transport, but its success in developing cities hinges on understanding how diverse users respond to specific service features. Comparative analyses between user groups, particularly those involving car versus public transport users, are limited, especially in developing countries. This study aims to assess the likelihood of adopting MaaS conditional on the presence of its core defining features, highlighting their role in enhancing service quality and passenger experience among 1243 private car and public transport users in Greater Accra, Ghana. Using ordinal logistic regression, we evaluate how seven core MaaS features, including real-time information and multimodal trip planning, shape adoption likelihood, and how this varies by socio-demographics, travel behaviour, and prior MaaS knowledge. The findings reveal strong support for real-time information and accessibility elements across user groups, while dynamic pricing and incentives, as well as multimodal trip planning, elicited scepticism, particularly among car users. Adoption likelihood was shaped not only by feature type but also by demographic characteristics: for instance, women and frequent public transport users showed greater interest in accessibility and seamless ticketing and payment features, while higher-income car users were more favourable to monthly subscription models. Findings have practical implications for inclusive mobility planning and equitable MaaS deployment in the Global South.
移动即服务(MaaS)有望改变城市交通,但它在发展中城市的成功取决于了解不同用户对特定服务功能的反应。用户群体之间的比较分析,特别是汽车与公共交通用户之间的比较分析是有限的,特别是在发展中国家。本研究旨在评估采用MaaS的可能性,条件是其核心定义特征的存在,突出其在提高服务质量和乘客体验方面的作用,在加纳大阿克拉的1243名私家车和公共交通用户中。使用有序逻辑回归,我们评估了七个核心MaaS特征(包括实时信息和多模式旅行计划)如何影响采用可能性,以及这如何随社会人口统计学、旅行行为和先前的MaaS知识而变化。调查结果显示,用户群体对实时信息和可访问性元素的强烈支持,而动态定价和激励措施以及多模式旅行计划则引起了怀疑,尤其是在汽车用户中。采用可能性不仅取决于功能类型,还取决于人口特征:例如,女性和经常使用公共交通工具的用户对可访问性和无缝票务和支付功能更感兴趣,而高收入的汽车用户更喜欢每月订阅模式。研究结果对全球南方的包容性移动规划和公平的MaaS部署具有实际意义。

Ports play a critical role in global trade and logistics, yet their efficiency must be assessed not only by operational performance but also through environmental sustainability metrics. This study evaluates the operational and environmental efficiency of Japan's top ten container ports using data envelopment analysis, combining both slacks-based measures and the undesirable output models. The research results show that Tokyo, Yokohama, and Kobe ports perform best in operational efficiency, with efficiency scores of 1.000; while Tomakomai and Hakata ports have low scores of 0.233 and 0.363, respectively, due to insufficient infrastructure utilization. In terms of environmental efficiency, Kobe and Yokohama ports also perform well, with efficiency values of 1.000, while Tomakomai Port has the lowest environmental efficiency of only 0.084. The result found that high-efficiency ports usually have advanced automation equipment and green infrastructure, while low-efficiency ports face problems of inefficient energy utilization and high emission intensity. The dual efficiency evaluation framework constructed in this research provides port managers and policymakers with a quantitative basis for green port transformation and supports Japan's sustainable port development path planning under the decarbonization goals.
港口在全球贸易和物流中发挥着关键作用,但其效率不仅要通过运营绩效来评估,还要通过环境可持续性指标来评估。本研究使用数据包络分析,结合基于松弛的度量和不良产出模型,评估了日本十大集装箱港口的运营和环境效率。研究结果表明,东京港、横滨港和神户港的运营效率表现最好,效率得分为1000分;而Tomakomai港和博多港由于基础设施利用率不足,得分分别为0.233和0.363。在环境效率方面,神户港和横滨港也表现良好,效率值为1.000,而Tomakomai港的环境效率最低,仅为0.084。结果发现,高效港口通常具有先进的自动化设备和绿色基础设施,而低效港口则面临能源利用效率低和排放强度高的问题。本研究构建的双重效率评价框架为港口管理者和政策制定者提供了绿色港口转型的量化依据,为日本脱碳目标下的港口可持续发展路径规划提供了支持。

This study presents a comprehensive Quantitative Risk Analysis (QRA) framework for assessing road transport accidents involving dangerous goods in Turkiye. The proposed methodology integrates national accident statistics, scenario-based event tree modeling, and ALOHA software/ correlations for consequence and impact assessment. Three representative routes in İzmir were selected as pilot areas to evaluate accident frequencies, physical impact zones, and associated individual and societal risks. Results indicate that LNG and LPG transport pose the highest risk levels, with scenario frequencies exceeding the regulatory threshold (1 × 10−4/year). Population exposure analysis revealed that social risk varies significantly with local demographic density. Sensitivity analyses confirmed that both the frequency of the initiating event and population distribution are critical determinants of total risk. The study presents a data-driven, nationally adapted QRA model aligned with Turkish transport infrastructure and regulations, providing a robust decision-support tool for improving road safety and emergency preparedness in dangerous goods logistics.
本研究提出了一个全面的定量风险分析(QRA)框架评估道路运输事故涉及危险货物在土耳其。所提出的方法集成了国家事故统计、基于场景的事件树建模和ALOHA软件/相关性,用于后果和影响评估。在İzmir选择了三条有代表性的路线作为试点地区,以评估事故频率、物理影响区以及相关的个人和社会风险。结果表明,液化天然气和液化石油气运输的风险水平最高,情景频率超过了监管阈值(1 × 10−4/年)。人口暴露分析显示,社会风险随地方人口密度的不同而有显著差异。敏感性分析证实,起始事件的频率和人群分布是总风险的关键决定因素。该研究提出了一个与土耳其运输基础设施和法规相一致的数据驱动的、适合全国的QRA模型,为改善危险品物流中的道路安全和应急准备提供了一个强大的决策支持工具。

Are the most cost-efficient train lines providing the best service? This study demonstrates that efficiency models often misidentify operational success, rewarding lines with significant service quality deficits. Based on a granular analysis of 174 line-year observations across 58 French regional railway lines, we propose and apply a new efficiency framework. By incorporating essential Quality of Service indicators (punctuality, regularity, frequency and crowding) into the evaluation, we reveal a fundamental reshuffling of performance rankings. Our findings show a clear divergence: cost-efficient lines with poor service are penalized, while lines delivering high-quality service see their performance scores improve significantly. The analysis further identifies the distinct characteristics of lines that experience the greatest changes in rank. As France moves towards competitive tendering in the rail sector, these results carry significant policy implications. A sole focus on cost-efficiency risks incentivizing service degradation. This research offers Public Transport Authorities a robust, quality-aware tool to facilitate more accurate performance diagnostics, identify benchmark lines, and ultimately foster a system that prioritizes both economic viability and passenger welfare.
最具成本效益的火车线路是否提供最好的服务?本研究表明,效率模型经常错误地识别运营成功,奖励具有显著服务质量缺陷的线路。基于对法国58条区域铁路线上174条线路年观测数据的细致分析,我们提出并应用了一个新的效率框架。通过将基本的服务质量指标(准点率、规律性、频率和拥挤程度)纳入评估,我们揭示了绩效排名的根本重组。我们的研究结果显示了明显的差异:服务质量差的低成本线路会受到惩罚,而提供高质量服务的线路的绩效得分会显著提高。分析进一步确定了经历最大等级变化的线条的独特特征。随着法国在铁路部门转向竞争性招标,这些结果具有重要的政策含义。只注重成本效益可能会刺激服务退化。这项研究为公共交通当局提供了一个强大的、具有质量意识的工具,以促进更准确的绩效诊断,确定基准线路,并最终建立一个优先考虑经济可行性和乘客福利的系统。

Hazardous material (hazmat) transportation presents considerable public safety and regulatory challenges, especially in dense urban environments. While drones are gaining traction as a viable solution for last-mile hazmat delivery, the literature has yet to present a comprehensive framework that integrates real-time risk mitigation with multi-stakeholder consequence assessment. This study addresses this critical gap by introducing a novel drone-based hazmat transportation framework built on two core innovations: the Accident Prediction and Mitigation System (APRiMS) and a multi-dimensional risk prediction suite. APRiMS functions as an autonomous decision-support engine, continuously processing real-time flight, shipment, and environmental data to estimate accident likelihood and initiate mitigation measures. In parallel, the framework incorporates four machine learning models that predict the potential impacts of drone-related incidents on the public, businesses, and customers. These components operate within a closed-loop architecture, wherein risk predictions dynamically inform APRiMS decisions, enabling real-time, consequence-aware operational responses. The proposed framework offers a scalable and intelligent deployment of drones for high-risk logistics.
危险物质(危险品)运输提出了相当大的公共安全和监管挑战,特别是在密集的城市环境中。虽然无人机作为最后一英里危险品运送的可行解决方案越来越受欢迎,但文献尚未提出一个综合的框架,将实时风险缓解与多利益相关者后果评估相结合。本研究通过引入一种新的基于无人机的危险品运输框架来解决这一关键差距,该框架建立在两个核心创新之上:事故预测和缓解系统(APRiMS)和多维风险预测套件。APRiMS作为自主决策支持引擎,持续处理实时飞行、运输和环境数据,以估计事故可能性并启动缓解措施。与此同时,该框架还结合了四个机器学习模型,用于预测无人机相关事件对公众、企业和客户的潜在影响。这些组件在闭环体系结构中运行,其中风险预测动态地通知APRiMS决策,从而实现实时的、后果感知的操作响应。拟议的框架为高风险物流提供了可扩展和智能的无人机部署。

This study investigates critical hazards associated with air transportation within cold chain logistics, focusing on the delivery of time-sensitive and perishable goods. Despite the growing importance of maintaining strict temperature control, there is a notable gap in research specifically targeting hazards in air cold chain logistics. Through an extensive literature review, 15 key hazards were identified and systematically categorized into five major groups: shipper, aircraft, apron, warehouse, and customs. To quantitatively assess these hazards, a hybrid approach combining Failure Modes and Effects Analysis (FMEA) with a Rule-based Bayesian Network (RBN) was employed, complemented by sensitivity analysis to ensure model robustness. Results reveal that hazards related to the shipper, aircraft, and apron exert the greatest impact, highlighting the critical role these stakeholders play in maintaining cold chain integrity. Based on these findings, targeted recommendations are proposed to mitigate risks effectively. The insights gained aim to enhance operational performance and reliability in air cold chain logistics, thereby strengthening the competitiveness and sustainability of the air cargo industry. This research helps bridge the existing knowledge gap and offers a practical framework for risk management in air cold chain transportation.
本研究调查了冷链物流中与航空运输相关的关键危害,重点是时间敏感和易腐货物的交付。尽管保持严格的温度控制越来越重要,但在专门针对空气冷链物流危害的研究方面存在明显的差距。通过广泛的文献回顾,确定了15个主要危害,并系统地分为五大类:托运人,飞机,停机坪,仓库和海关。为了定量评估这些风险,采用了一种将失效模式和影响分析(FMEA)与基于规则的贝叶斯网络(RBN)相结合的混合方法,并辅以敏感性分析以确保模型的鲁棒性。结果显示,与托运人、飞机和停机坪相关的危害影响最大,突出了这些利益相关者在保持冷链完整性方面发挥的关键作用。根据这些发现,提出了有针对性的建议,以有效减轻风险。研究的目的是提高空气冷链物流的运作表现和可靠性,从而加强航空货运业的竞争力和可持续性。这项研究有助于弥合现有的知识差距,并为空气冷链运输的风险管理提供了一个实用的框架。

The research aims to elucidate the impact of corporate sustainable policies on the reduction of carbon footprint within the business travel sector, with a focus on the mediating role of employee consciousness and the moderating influence of travel technology adoption. A survey-based, time-lagged study was conducted, drawing on responses from employees across various industries engaged in corporate travel. Findings suggest that corporate sustainable policies significantly contribute to the reduction of carbon footprint when employees exhibit high levels of environmental consciousness. Furthermore, the adoption of travel technologies was found to enhance this relationship, albeit differentially across various levels of technology integration. The study's implications emphasize the importance of fostering employee environmental consciousness and investing in travel technology for businesses aiming to realize their sustainability objectives. These insights have practical ramifications for corporate policy formulation, suggesting a strategic alignment of human resource initiatives with sustainability goals to amplify environmental performance.
本研究旨在阐明企业可持续发展政策对商旅部门碳足迹减少的影响,重点研究员工意识的中介作用和旅行技术采用的调节作用。我们进行了一项基于调查的滞后研究,收集了从事商务旅行的不同行业员工的反馈。研究结果表明,当员工表现出高水平的环境意识时,企业可持续发展政策显著有助于减少碳足迹。此外,旅游技术的采用也增强了这种关系,尽管在不同的技术整合水平上存在差异。该研究强调了培养员工环保意识和投资旅游技术对企业实现可持续发展目标的重要性。这些见解对公司政策制定具有实际影响,建议将人力资源倡议与可持续发展目标进行战略协调,以扩大环境绩效。

Green shipping technologies (GSTs) are widely acknowledged as indispensable for facilitating a green transition in the maritime sector. Technological collaboration is especially vital for developing GSTs. However, the technological collaboration network of GSTs has been underexplored. To fill this gap, this study investigates technological collaboration patterns and evolutionary characteristics amongst GST-related research communities by measuring two patent cooperation networks. Results show that the GST collaboration network evolved to much bigger and more actors, but still a quite sparse network, which is in the initial stage of development. Daewoo is identified as the most prominent key actor in the network. Four blocks are found, but the links between the blocks are weak, and the spillover effect is insignificant. This study not only enriches the sustainable shipping management and transition literature by identifying the dynamics and structure of the global GST collaboration network, but also provides valuable insights and suggestions for promoting GSTs and accelerating the green transformation of the shipping industry through collaborative innovation.
绿色航运技术(gst)被广泛认为是促进海事部门绿色转型不可或缺的技术。技术合作对发展商品及服务税尤其重要。然而,商品及服务服务的技术合作网络尚未得到充分探索。为了填补这一空白,本研究通过测量两个专利合作网络,探讨了gst相关研究团体之间的技术合作模式及其演化特征。结果表明:商品及服务税协同网络已发展到规模更大、参与者更多的阶段,但仍然是一个相当稀疏的网络,处于初级发展阶段;大宇被认为是网络中最突出的关键角色。发现了四个区块,但区块之间的联系较弱,溢出效应不显著。本研究不仅通过识别全球GST协同网络的动态和结构丰富了可持续航运管理和转型文献,而且为通过协同创新推动GST和加速航运业绿色转型提供了有价值的见解和建议。

The transition from a linear to a circular economy in food and agriculture supply chains has attracted scholars and managers due to increasing demands and environmental concerns. Incorporating sustainability with circular supply chain and transportation systems, not only addresses global environmental issues but also prevents the excessive use of non-renewable resources while covering economic and social concerns. Contrary to earlier studies, this study proposes a new sustainable circular agriculture supply chain and logistics network, incorporating a multi-objective mixed-integer linear programming model that considers current important real-world business concerns, like water consumption, agrochemical use, and new Agrivoltaic technologies. These factors are integrated to enhance transportation efficiency, productivity, revenue, and employment. Key logistic components such as facility location, transportation, inventory, and warehousing are addressed within this optimization framework. The feasibility of the proposed network is evaluated through a case in Northern Iran, addressed by the General Revised Multi-Choice Goal Programming method. Besides, this study develops a new modified multi-objective meta-heuristic algorithm, alongside other famous ones, with a comprehensive tuning strategy to tackle the proposed test problems. The performance of the algorithms is evaluated by several indicators, and a new hybrid multi-objective decision-making approach is proposed to ease the comparison of the algorithms. Adjustments in influential logistics and transportation parameters and different aspects of the proposed problem are explored through several sensitivity analyses. The results highlight the importance of facility location, effective Agrivoltaic technology, strategic product transportation, and inventory planning, which enhance circular and sustainable advancements in agri-food transportation and logistic industries.
由于日益增长的需求和对环境的担忧,食品和农业供应链从线性经济向循环经济的转变吸引了学者和管理者。将可持续发展与循环供应链和运输系统相结合,不仅可以解决全球环境问题,还可以防止过度使用不可再生资源,同时兼顾经济和社会问题。与早期的研究相反,本研究提出了一个新的可持续循环农业供应链和物流网络,结合了一个多目标混合整数线性规划模型,该模型考虑了当前重要的现实世界商业问题,如用水量、农用化学品使用和新的农业光伏技术。这些因素综合起来可以提高运输效率、生产力、收入和就业。关键的物流组件,如设施位置、运输、库存和仓储都在这个优化框架中得到解决。通过伊朗北部的一个案例,用通用修正多选择目标规划方法对拟议网络的可行性进行了评估。此外,本研究还开发了一种新的改进的多目标元启发式算法,并采用综合调优策略来解决所提出的测试问题。通过多个指标对算法的性能进行评价,提出了一种新的混合多目标决策方法来简化算法之间的比较。通过几个敏感性分析,探讨了影响物流和运输参数的调整以及所提出问题的不同方面。研究结果强调了设施选址、有效的农业光伏技术、战略性产品运输和库存规划的重要性,这些都促进了农业食品运输和物流行业的循环和可持续发展。

This paper demonstrates how air traffic services, by collaborating closely with airline customers, can implement environmental initiatives that also yield financial benefits through the application of Lean Six Sigma techniques. By streamlining operational processes -specifically those related to the descent and arrival phases of flight - aviation stakeholders can reduce fuel consumption and associated CO₂ emissions, contributing to a more sustainable and environmentally responsible industry. The research involved redesigning a process using Lean Six Sigma tools to optimize outcomes for both cost efficiency and environmental impact. The initiative, focused on aircraft arriving at Cork Airport, engaged multiple stakeholders including a neighbouring Air Navigation Service Provider and the Dublin Airport Authority. Findings reveal that by actively listening to both internal and external customer voices and applying Lean Six Sigma principles, air traffic services can effectively eliminate waste, enhance operational efficiency, and deliver measurable environmental improvements. While Lean Six Sigma has been widely adopted across various sectors of aviation, its application within air traffic control remains limited. This study offers a novel contribution by illustrating how these methodologies can be successfully employed in a highly regulated domain to drive meaningful change.
