The transportation sector in the Kingdom of Saudi Arabia (KSA) is a major contributor to greenhouse gas (GHG) emissions, driven by the country's heavy reliance on oil and fossil fuels. Transitioning to a green and sustainable transport system is critical for reducing emissions and aligning with Saudi Arabia's Vision 2030 goals of diversifying its economy and promoting environmental sustainability. Thus, this research examined the adoption of a green sustainable transport system to reduce GHG emissions and reduce dependence on fossil fuels for sustainable development in the KSA. The study evaluates various factors and Artificial Intelligence (AI)-based eco-driving solutions to systematically implement green transportation systems. In this study, the Fuzzy Analytical Hierarchy Process (FAHP) method is applied to evaluate the five factors and eighteen sub-factors crucial for developing a green transportation system in the country. Next, the Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS) method is used to prioritize the most significant AI-based eco-driving solutions for the implementation of smart and green transportation in KSA. The findings of the FAHP show that environmental impact (33 %) is the most crucial factor, followed by regulatory compliance (21.3 %) and economic viability (16.9 %). The FTOPSIS indicates that the smart navigation system (CC_i = 0.682) is the most critical AI-based eco-driving solution because this can help reduce GHG emissions and increase the efficiency of traffic regulation in the country. The electric and hybrid vehicle integration (CC_i = 0.585) and carbon footprint tracking systems (CC_i = 0.355) are the next most significant solutions. This study is helpful in reducing GHG emissions, supporting sustainable development, and guiding policymakers toward effective green transport initiatives.

沙特阿拉伯王国（KSA）严重依赖石油和化石燃料，交通运输部门是温室气体（GHG）排放的主要来源。过渡到绿色和可持续的交通系统对于减少排放和符合沙特阿拉伯2030年愿景的目标至关重要，该目标旨在实现经济多元化和促进环境可持续性。因此，本研究探讨了在沙特阿拉伯采用绿色可持续交通系统以减少温室气体排放和减少对化石燃料的依赖以实现可持续发展。该研究评估了各种因素和基于人工智能（AI）的生态驾驶解决方案，以系统地实施绿色交通系统。本研究采用模糊层次分析法（FAHP）对我国发展绿色交通系统的5个关键因素和18个子因素进行了评价。接下来，使用模糊理想解决方案相似度偏好排序技术（FTOPSIS）方法对最重要的基于人工智能的生态驾驶解决方案进行优先排序，以实现KSA的智能和绿色交通。FAHP的研究结果显示，环境影响（33%）是最关键的因素，其次是法规遵从（21.3%）和经济可行性（16.9%）。FTOPSIS表明，智能导航系统（CCi = 0.682）是最关键的基于人工智能的生态驾驶解决方案，因为这有助于减少温室气体排放，提高该国的交通管制效率。电动和混合动力汽车集成（CCi = 0.585）和碳足迹跟踪系统（CCi = 0.355）是第二重要的解决方案。这项研究有助于减少温室气体排放，支持可持续发展，并指导决策者采取有效的绿色交通举措。

Digitalization has been increasing in nearly all aspects of society, facilitating new opportunities. One example is the increase in online shopping opportunities which in turn results in increased home (or near-home) deliveries. This shift within last-mile distribution must be considered by local authorities, both regarding its impacts on traditional city center deliveries, and also the expansion of last-mile deliveries to residential areas where the infrastructure is not designed to safely or efficiently accommodate larger freight vehicles. Increased understanding of the impacts of digital transitions on urban mobility is needed to better integrate freight and logistics into urban planning and to establish strategies and policies for supporting urban freight and last-mile transitions. At the same time, this digitalization provides further opportunities for knowledge development by expanding the availability and richness of data. Local authorities must initiate collaboration with the private sector (i.e., logistics service providers, receivers, and end consumers) to develop policies that facilitate the collection of last-mile delivery data in ways that benefit all stakeholders. This study, motivated by a mapping of last-mile deliveries to shopping malls, reflects on these issues, and then further suggests areas for future research and strategies for local authorities to consider.

数字化几乎在社会的各个方面都在增加，创造了新的机会。一个例子是网上购物机会的增加，这反过来又导致了家庭（或近家）送货的增加。地方当局必须考虑到最后一英里配送的这种转变，既要考虑到它对传统的市中心配送的影响，也要考虑到将最后一英里配送扩展到居民区，因为那里的基础设施无法安全或有效地容纳大型货运车辆。需要进一步了解数字化转型对城市交通的影响，以便更好地将货运和物流纳入城市规划，并制定支持城市货运和最后一英里转型的战略和政策。与此同时，这种数字化通过扩大数据的可用性和丰富性，为知识发展提供了进一步的机会。地方当局必须启动与私营部门（即物流服务提供商、接收方和最终消费者）的合作，以制定有利于所有利益相关者的方式收集最后一英里交付数据的政策。这项研究的动机是对购物中心的最后一英里配送进行测绘，它反映了这些问题，然后进一步提出了未来研究的领域和地方当局考虑的策略。

This paper investigates the adoption and operational challenges of electric jeepneys (E-jeepneys) within the framework of the Philippine Public Utility Vehicle Modernization Program (PUVMP). Through qualitative case studies of 4 jeepney entities, the study explores primary motivations, business models, and challenges encountered during the transition from traditional to E-jeepneys. Key findings emphasize the important role of government subsidies, alternative financing schemes, and local government support in facilitating vehicle acquisition, route planning, and smooth operations. Operational benefits, such as reduced costs and enhanced service capabilities through cooperative alliances, are identified as critical factors contributing to the successful adoption of E-jeepneys. However, challenges remain in infrastructure development, operational sustainability, and regulatory alignment across diverse localities. The study underscores the importance of tailored policies, robust infrastructure investments, and sustainable business models to support ongoing transport modernization efforts. These insights may guide policymakers and stakeholders navigating similar initiatives globally.

本文调查了菲律宾公共事业车辆现代化计划（PUVMP）框架内电动吉普尼（E-jeepneys）的采用和运营挑战。通过对4个吉普尼实体的定性案例研究，本研究探讨了从传统吉普尼向电动吉普尼过渡的主要动机、商业模式以及遇到的挑战。主要研究结果强调了政府补贴、替代融资方案和地方政府支持在促进车辆购置、路线规划和顺利运营方面的重要作用。运营效益，如通过合作联盟降低成本和增强服务能力，被认为是成功采用e -jeepney的关键因素。然而，在基础设施建设、运营可持续性和各地监管协调方面仍存在挑战。该研究强调了有针对性的政策、稳健的基础设施投资和可持续的商业模式对支持正在进行的交通现代化工作的重要性。这些见解可以指导决策者和利益相关者在全球范围内开展类似的举措。

Crowdshipping has grown in popularity as a sharing economy model, but ensuring its sustainability remains a challenge. This study explores how public transit riders can be engaged in crowdshipping services to avoid generating additional motorized traffic. The propensity of public transit users to participate in crowdshipping and their responses to alternative task attributes are explored through an in-person survey conducted at selected subway stations in Stockholm. The influence of different socio-demographic factors and trip features on the propensity for participation is examined using statistical analysis and regression models. To quantify the trade-offs among required detours, compensation, and parcel weight when accepting crowdshipping tasks, alternative discrete choice models are investigated. The results reveal that factors such as age, employment, and income, along with trip characteristics, significantly affect participation propensity. The estimated willingness to work as a crowdshipper aligns with previous studies showing that age and income level were important factors. A latent class model further reveals a clear division between two groups: one younger, lower income group with higher willingness to work, and another older, higher-income group with lower willingness. As a result, dedicated strategies need to be considered by future crowdshipping service providers and policymakers.

众筹作为一种共享经济模式越来越受欢迎，但确保其可持续性仍然是一个挑战。本研究探讨了公共交通乘客如何参与众包服务，以避免产生额外的机动交通。通过在斯德哥尔摩选定的地铁站进行的面对面调查，探讨了公共交通用户参与众包的倾向以及他们对替代任务属性的反应。利用统计分析和回归模型考察了不同社会人口因素和旅行特征对参与倾向的影响。为了量化在接受众包任务时所需的弯路、补偿和包裹重量之间的权衡，研究了可选的离散选择模型。结果表明，年龄、就业、收入等因素以及出行特征对参与倾向有显著影响。据估计，作为众包商的意愿与之前的研究一致，表明年龄和收入水平是重要因素。潜在阶级模型进一步揭示了两个群体之间的明确划分：一个是年轻的、收入较低的、工作意愿较高的群体，另一个是年龄较大的、收入较高的、工作意愿较低的群体。因此，未来的众包服务提供商和政策制定者需要考虑专门的策略。

This study examines how external price shocks originating in global energy markets (Brent and Dubai oil) and maritime freight systems (BDTI and BCTI) are transmitted to consumer price indices (CPI) in four economies of the Global South: China, India, South Korea, and Saudi Arabia. Using a time–frequency connectedness framework, the analysis captures the evolving intensity and directionality of inflationary spillovers across short, medium, and long-term horizons. The findings reveal that freight indices not only mediate energy shocks but increasingly act as independent inflationary forces—suggesting the emergence of logistics infrastructures as systemic amplifiers of global price volatility. The analysis shows that energy-importing economies such as China and South Korea are persistently exposed to externally induced price instability, particularly in economies with high energy-import dependence such as China and South Korea, though the categorization does not imply a uniform geopolitical or developmental status. These results challenge domestic-centered views of inflation and underscore the need for a structural understanding of global price formation that accounts for trade dependence, transport asymmetries, and geopolitical exposure.

本研究考察了源自全球能源市场（布伦特和迪拜石油）和海运系统（BDTI和BCTI）的外部价格冲击如何传导到全球南方四个经济体（中国、印度、韩国和沙特阿拉伯）的消费者价格指数（CPI）。该分析利用时-频连通性框架，捕捉了通胀溢出效应在短期、中期和长期范围内不断变化的强度和方向性。研究结果表明，货运指数不仅可以调节能源冲击，而且越来越多地成为独立的通胀力量，这表明物流基础设施的出现是全球价格波动的系统性放大器。分析表明，能源进口经济体，如中国和韩国，持续暴露于外部引起的价格不稳定，特别是在能源进口高度依赖的经济体，如中国和韩国，尽管分类并不意味着统一的地缘政治或发展地位。这些结果挑战了以国内为中心的通货膨胀观点，并强调需要对全球价格形成进行结构性理解，以解释贸易依赖、运输不对称和地缘政治风险。

We investigate gasoline demand growth in Brazil over a 16-year period, assessing its response to electric vehicle (EV) adoption and taxation measures. Using a spatial-based econometric model with data from 2006 to 2021 across all Brazilian states, we observe that annual gasoline sales nearly doubled from 2006 to 2014, reaching 0.22 m³ per capita, and then stabilized. Our model reveals that the EV motorization rate negatively impacts gasoline demand, with an elasticity of −0.126, compared to 0.609 for internal combustion engine vehicles. The results show that aggressive fuel taxation alone is insufficient to achieve long-term reductions in demand. However, fleet electrification is more effective, potentially reducing per capita gasoline consumption by 90% between 2021 and 2034 when it is strongly incentivized. A combined approach integrating taxation and electrification offers the most efficient pathway for reducing demand while generating revenue for public investment in Brazil’s transition to a carbon-free transportation sector.

我们调查了巴西16年来的汽油需求增长，评估了其对电动汽车（EV）采用和税收措施的反应。我们使用基于空间的计量经济模型，分析了2006年至2021年巴西各州的数据，发现从2006年到2014年，巴西的汽油年销量几乎翻了一番，达到人均0.22立方米，之后趋于稳定。我们的模型显示，电动汽车机动化率对汽油需求的影响为负，弹性系数为- 0.126，而内燃机汽车的弹性系数为0.609。研究结果表明，仅靠征收高额燃油税不足以实现需求的长期减少。然而，车队电气化更有效，在2021年至2034年期间，如果得到强有力的激励，人均汽油消耗量可能会减少90%。在巴西向无碳交通部门转型的过程中，税收和电气化相结合的方法为减少需求，同时为公共投资创造收入提供了最有效的途径。

The bodily injury severity of a vehicle involved in a crash has traditionally been defined in literature as the one associated with the most serious injured occupant and, therefore, excluding from the analysis the injured victims other than the most serious one. In this study, we propose an aggregate injury severity indicator for a crashed vehicle, based on the alternative metrics used in road safety research to calculate the monetary value of the change in risk of death and injury for each person in the vehicle. The main advantage of our indicator is that, by projecting the different qualitative levels of injury severity into monetary values, it allows aggregating the injury severity levels sustained by all occupants of a vehicle into a single value. We analyse the effect of the gender of the driver and its interaction with other risk factors on the expected monetary value of the injury risk of the vehicle. We found evidence of gender differences in driving, consistent with ‘couple driving behaviour’, where a man is more likely to be the driver when a woman (presumably the couple) is also in the vehicle. When the driver was a woman, the expected monetary value of the injury risk was on average reduced by 22 % for the occupants of the vehicle, and by 34 % for the passengers, i.e. excluding the driver's injuries. The reduction of the monetary value of the injury risk of passengers was higher for young female drivers than for old ones, with young-older female drivers (aged 66–74 years) being riskier for occupants than the young-older male drivers. In conclusion, analysing the gender differences in the aggregate expected injury severity for all occupants of the vehicle provides road safety policy makers with a better approximation of the injury severity resulting from motor vehicle crashes.

传统上，在文献中，涉及碰撞的车辆的身体伤害严重程度被定义为与受伤最严重的乘员相关的伤害严重程度，因此，从分析中排除了除最严重的受害者以外的受伤受害者。在这项研究中，我们基于道路安全研究中使用的替代指标，提出了碰撞车辆的总伤害严重程度指标，以计算车辆中每个人的死亡和受伤风险变化的货币价值。我们的指标的主要优点是，通过将不同的伤害严重程度的定性水平投射到货币价值中，它可以将车辆中所有乘员所遭受的伤害严重程度汇总到一个单一的值中。我们分析了驾驶员的性别及其与其他风险因素的相互作用对车辆伤害风险的预期货币价值的影响。我们发现了驾驶中存在性别差异的证据，这与“夫妻驾驶行为”是一致的，即当女性（大概是夫妻）也在车里时，男性更有可能是司机。当司机是女性时，车内人员受伤风险的预期货币价值平均降低了22%，乘客的预期货币价值平均降低了34%，即不包括司机的伤害。与老年司机相比，年轻女性司机对乘客伤害风险的货币价值降低更高，年龄在66-74岁之间的年轻女性司机比年龄在年轻男性司机对乘客的风险更高。总之，分析车辆中所有乘员的总体预期伤害严重程度的性别差异，为道路安全政策制定者提供了一个更好的近似机动车辆碰撞造成的伤害严重程度。

The main advantage of our indicator is that, by projecting the different qualitative levels of injury severity into monetary values, it allows aggregating the injury severity levels sustained by all occupants of a vehicle into a single value. We analyse the effect of the gender of the driver and its interaction with other risk factors on the expected monetary value of the injury risk of the vehicle. We found evidence of gender differences in driving, consistent with ‘couple driving behaviour’, where a man is more likely to be the driver when a woman (presumably the couple) is also in the vehicle. When the driver was a woman, the expected monetary value of the injury risk was on average reduced by 22 % for the occupants of the vehicle, and by 34 % for the passengers, i.e. excluding the driver's injuries. The reduction of the monetary value of the injury risk of passengers was higher for young female drivers than for old ones, with young-older female drivers (aged 66–74 years) being riskier for occupants than the young-older male drivers.

With the extensive adoption of electrification technology in China's new energy vehicle market, traditional automakers are accelerating their transition towards electrification, thereby reshaping the competitive landscape. Meanwhile, mobile communication technology, which serves as the foundation of networking and intelligent development, not only facilitates the rapid emergence of new automotive manufacturers but also introduces novel opportunities and challenges to the new energy vehicle industry. This study employs a discrete choice model to empirically analyze how network configuration impacts the sales of new energy vehicles, aiming to explore how network connectivity empowers these vehicles in the post-subsidy era. The findings demonstrate that: (1) The mobile network configuration can positively affect the market share of new energy vehicle products, among which consumer satisfaction plays a partial mediating role. (2) From the perspective of specific network configuration, the impact on automotive market share is mainly driven by the role of 4G network, while the impact of 4G to 5G network upgrade is a gradual process. (3) For domestic car brands and car brands with relatively low prices, network integration plays a more obvious role in improving the car market share.

Ground access mode choice directly impacts an airport's commercial income generation, imposes a range of environmental externalities and requires often-considerable capital investment and infrastructure development. Historically, these revenue planning, environmental management and capital investment decisions were predicated on the knowledge that airport ground access occurred via private vehicles or by conventional public transport modes. However, the introduction of new forms of ride-hailing and ridesharing mobility services by Transportation Network Companies (TNCs) is disrupting the status quo and posing new revenue and infrastructure planning challenges for airports. Australia is one country experiencing this new business model. The aim of this paper is to examine the situation in Australia and explore the extent to which major passenger airports in the country are adapting to the advent of TNCs and ridesharing services. The situation at the 10 busiest passenger airports is examined. The findings show that while these airports still routinely plan for conventional forms of ground access, TNC's represent a trend breaker which demands new ground access management strategies. Recommendations to help airport management respond to the introduction of widespread ridesharing and the arrival of TNCs in terms of landside asset configuration and the potential for regulatory and financial strategies are proposed.

地面通道模式的选择直接影响机场的商业收入，带来一系列的环境外部性，并且通常需要相当大的资本投资和基础设施建设。从历史上看，这些收入规划、环境管理和资本投资决策都是基于私人车辆或传统公共交通方式进入机场的知识。然而，运输网络公司（TNCs）引入的新形式的叫车和拼车移动服务正在打破现状，并对机场的收入和基础设施规划提出了新的挑战。澳大利亚就是一个正在经历这种新商业模式的国家。本文的目的是研究澳大利亚的情况，并探讨该国主要客运机场适应跨国公司和拼车服务出现的程度。调查了10个最繁忙的客运机场的情况。调查结果表明，虽然这些机场仍然按照常规方式规划地面通道，但TNC代表了一种趋势，需要新的地面通道管理策略。本文提出了建议，以帮助机场管理部门在陆地资产配置以及监管和财务战略的潜力方面应对广泛的拼车和跨国公司的到来。

The market for used vehicles has grown rapidly worldwide. However, information asymmetries and a lack of quality guarantees negatively influence consumer participation in this market. In this study, we conduct an online survey with discrete choice experiments to elicit consumer preferences for e-commerce platforms aimed at facilitating used vehicle transactions in China. Our experimental design includes a suite of attributes that are representative of current e-commerce platforms for used vehicles, covering the type of sellers, the provision of multiple essential services (e.g., loan, insurance, and inspection), and service fees charged by platforms when transactions occur. Estimating mixed logit models using our survey data, we find that providing information on the available services alone does not significantly affect consumers' choice of e-commerce platforms for used vehicles. However, respondents substantially value additional services offered by the platform and are willing to pay extra service fees, especially for inspection services. Our results provide new evidence on how consumers perceive e-commerce platforms for used vehicles and highlight the importance of inspections in consumers’ decisions on purchasing used vehicles through e-commerce platforms.

二手车市场在世界范围内迅速增长。然而，信息不对称和缺乏质量保证对消费者参与这个市场产生了负面影响。在这项研究中，我们通过离散选择实验进行在线调查，以了解消费者对旨在促进中国二手车交易的电子商务平台的偏好。我们的实验设计包括一套代表当前二手车电子商务平台的属性，涵盖卖家类型、提供多种基本服务（如贷款、保险和检验）以及交易发生时平台收取的服务费。使用我们的调查数据估计混合logit模型，我们发现单独提供可用服务的信息并不会显著影响消费者对二手车电子商务平台的选择。然而，受访者非常重视平台提供的额外服务，并愿意支付额外的服务费，特别是检查服务。我们的研究结果为消费者如何看待二手车电子商务平台提供了新的证据，并强调了检查在消费者通过电子商务平台购买二手车决策中的重要性。
