The COVID-19 pandemic has triggered pronounced fluctuations in the shipping market, complicating decisions on freight rate setting, capacity allocation, and investment planning. Understanding how inflation influences container shipping is therefore essential for shipping companies seeking to anticipate market changes more accurately. This study examines the nonlinear relationship between container freight rates and inflation, focusing on the China–Europe route and the China–North America West Coast route. To ensure robust results, the analysis incorporates three control variables: port congestion index, container trade index, and container fleet growth. The findings reveal an inverted N-shaped relationship between inflation and freight rates, with two inflection points demarcating shifts in the direction of the effect: inflation exerts a positive influence within the range between the two points but a negative influence outside it. The inflection points observed in this study are higher for the United States compared to Europe, likely due to differences in economic performance and monetary policy. These results highlight the need for shipping companies to adapt their operational and pricing strategies based on the specific economic conditions of the regions in which they operate.

新冠肺炎疫情引发航运市场剧烈波动，使运价设定、运力分配和投资规划等决策复杂化。因此，了解通货膨胀如何影响集装箱运输对于寻求更准确地预测市场变化的航运公司至关重要。本文以中国-欧洲航线和中国-北美西海岸航线为研究对象，探讨了集装箱运价与通货膨胀之间的非线性关系。为了确保稳健的结果，分析纳入了三个控制变量：港口拥堵指数、集装箱贸易指数和集装箱船队增长。研究结果揭示了通货膨胀和运费之间的倒n型关系，两个拐点划分了影响方向的变化：通货膨胀在两个拐点之间的范围内产生积极影响，但在这两个拐点之外产生消极影响。本研究中观察到的美国的拐点高于欧洲，可能是由于经济表现和货币政策的差异。这些结果突出表明，航运公司需要根据其经营所在地区的具体经济条件调整其业务和定价战略。

This paper investigates preference heterogeneity in the Value of Travel Time Savings (VTTS) among Express Lane (EL) users, highlighting how VTTS varies across individuals. The study contributes to the literature by demonstrating how travel demand modeling can be effectively conducted using a large, high-resolution dataset that integrates transponder-based Express Lane usage with travel time savings derived from probe vehicle data. VTTS is estimated through a trip generation model, where the dependent variable is trip frequency.

To address the absence of user-specific socio-demographic characteristics and to capture the full spectrum of preference heterogeneity, the study employs three advanced ordered logit models: the generalized ordered logit (GOL), the heteroskedastic ordered logit (HOL), and the latent class ordered logit (LCOL). Results reveal substantial heterogeneity in user preferences. Notably, infrequent Express Lane users demonstrate a higher willingness to pay for time savings compared to regular commuters, suggesting that EL usage patterns reflect deeper differences in value perception.

By identifying nuanced user segments and their evolving preferences, this study offers actionable insights for transportation agencies, planners, toll operators, and policymakers. The findings support the development of dynamic tolling and incentive-based strategies that are responsive to user diversity.

本文研究了快速通道（EL）用户出行时间节省价值的偏好异质性，重点分析了不同个体之间的差异。该研究通过展示如何使用大型高分辨率数据集有效地进行旅行需求建模，从而为文献做出了贡献，该数据集将基于应答器的快速车道使用情况与探测车辆数据节省的旅行时间相结合。通过一个行程生成模型来估计VTTS，该模型的因变量为行程频率。为了解决用户特定社会人口特征的缺失问题，并捕捉偏好异质性的全部范围，本研究采用了三种先进的有序logit模型：广义有序logit （GOL）、异方差有序logit （HOL）和潜在类别有序logit （LCOL）。结果揭示了用户偏好的实质性异质性。值得注意的是，与经常通勤的人相比，不经常使用快速通道的用户表现出更高的为节省时间而付费的意愿，这表明，快速通道的使用模式反映了价值感知的更深层次差异。通过识别细微差别的用户群体及其不断变化的偏好，本研究为交通运输机构、规划者、收费运营商和政策制定者提供了可操作的见解。研究结果支持根据用户多样性制定动态收费和基于奖励的战略。

As urban land increased in mainland Portugal by 55.9% between 1990 and 2012 and the country developed an extensive motorway network, we set out to investigate the effect of motorways on urban sprawl across mainland municipalities. We document the evolution of urban sprawl for these 275 municipalities across several dimensions, including the population density of urban land, its degree of fragmentation and shape irregularity (which we combine in a summary “total interface” indicator), and the differences between the central urban unit and “peripheral” urban land. Given that the spatial distribution of motorways is likely to be endogenous, we use road itineraries of the 18th century as an instrumental variable. Our results suggest that motorways contribute to the fragmentation of urban land into numerous urban patches. Also, we identify important within-municipality heterogenous effects, in that motorways do not cause the contiguous growth of the central urban unit, but contribute in a significant manner to the development of peripheral urban land. There is also some evidence that motorways contribute to an increase in the shape irregularity of urban areas. Finally, we show that motorways cause a decrease in urban population density, but only in the group of more urbanised municipalities.

1990年至2012年间，葡萄牙大陆的城市用地增加了55.9%，并且该国发展了广泛的高速公路网络，因此我们着手调查高速公路对大陆各城市城市扩张的影响。我们从几个维度记录了这275个城市的城市蔓延演变，包括城市土地的人口密度、破碎程度和形状不规则性（我们将其结合在一个总结的“总界面”指标中），以及中心城市单元和“外围”城市土地之间的差异。考虑到高速公路的空间分布可能是内生的，我们使用18世纪的道路路线作为工具变量。我们的研究结果表明，高速公路导致城市土地破碎成许多城市斑块。此外，我们还发现了重要的城市内部异质性效应，即高速公路不会导致中心城市单元的连续增长，但对周边城市土地的发展做出了重大贡献。还有一些证据表明，高速公路加剧了城市地区的形状不规则性。最后，我们表明高速公路导致城市人口密度下降，但仅在城市化程度较高的城市群体中。

New energy vehicle promotion (NEVP) is of considerable significance for improving road transportation efficiency (RTE) and promoting regional economic growth (REG). This study quantifies provincial RTE in China using panel data and employs a panel vector autoregression model to examine both static and dynamic relationships among NEVP, RTE, and REG. Through empirical measurement, it is found that the national RTE scores range between 0.80 and 0.86, exhibiting a non-monotonic trajectory. The eastern region recorded the highest average RTE of 0.86, while the central region showed the lowest, at 0.80. The northeastern region demonstrated the highest average NEVP at 8.31 %, whereas the western region had the lowest, at 2.73 %. According to REG indicators, the western region achieved the highest average annual GDP growth rate, reaching 9.18 %. The empirical analysis reveals that the relationship between NEVP and RTE is primarily characterized by mutual constraints. REG significantly facilitates NEVP, though with notable regional disparities: the promotive effect is stronger in both eastern and western regions compared to the central region. The marginal contribution of this study lies in employing the non-radial directional distance function to measure RTE, while integrating NEVP, RTE, and REG within a unified analytical framework for correlation analysis.

新能源汽车推广对于提高道路运输效率（RTE）和促进区域经济增长（REG）具有重要意义。本研究利用面板数据对中国省级RTE进行量化，并采用面板向量自回归模型来检验NEVP、RTE和REG之间的静态和动态关系。通过实证测量，发现全国RTE得分在0.80 ~ 0.86之间，呈现非单调轨迹。东部地区的平均RTE最高，为0.86，中部地区最低，为0.80。东北地区平均NEVP最高，为8.31%，西部地区最低，为2.73%。根据REG指标，西部地区年均GDP增长率最高，达到9.18%。实证分析表明，新经济价值与资源效率之间的关系主要表现为相互制约。REG对新农业发展具有显著的促进作用，但存在显著的区域差异：东部和西部地区的促进作用都强于中部地区。本研究的边际贡献在于采用非径向定向距离函数测量RTE，并将NEVP、RTE和REG整合在一个统一的分析框架内进行相关性分析。

Online grocery shopping with doorstep delivery is reshaping everyday decisions, often prioritising speed and convenience at the cost of higher transport emissions. Consumer choices are therefore central to promoting sustainability in this context. Grounded in the SHIFT model, this study explores how nudging strategies can promote sustainable behaviour among Generation Z consumers. Drawing on behavioural insights from Kahneman's book ‘Thinking, Fast and Slow’, which investigates how subtle cues influence decision-making. Two online surveys using a randomized experimental design tested nine nudging strategies. Among these, financial penalties and eco-label prompts proved most effective in encouraging slower delivery choices. Participants with prior pro-environmental awareness were less inclined to choose an express delivery, while older Gen Z respondents (closer to 30) tended to favour express delivery regardless of the nudge, suggesting that lifestyle differences shape responsiveness to nudges. These findings indicate that the success of a nudge depends not only on its design but also on consumers' prior awareness and demographic profiles. By focusing on the underexplored Generation Z segment and comparing a diverse range of nudges, this study contributes to behavioural research and offers actionable insights for retailers and policymakers aiming to reduce the environmental impact of last mile delivery.

在线购物和上门配送正在重塑日常决策，通常以更高的运输排放为代价，优先考虑速度和便利。因此，在这种情况下，消费者的选择对促进可持续性至关重要。本研究以SHIFT模型为基础，探讨了推动策略如何促进Z世代消费者的可持续行为。卡内曼在《思考，快与慢》一书中研究了微妙的线索是如何影响决策的。两项使用随机实验设计的在线调查测试了九种助推策略。其中，经济处罚和生态标签提示在鼓励选择较慢的交付方式方面被证明是最有效的。先前具有环保意识的参与者不太倾向于选择快递，而年龄较大的Z世代受访者（接近30岁）倾向于选择快递，而不管是否有推动，这表明生活方式的差异决定了他们对推动的反应。这些发现表明，轻推的成功不仅取决于它的设计，还取决于消费者先前的意识和人口统计资料。通过关注未被充分开发的Z世代群体，并比较各种各样的推动因素，本研究有助于行为研究，并为旨在减少最后一英里配送对环境影响的零售商和政策制定者提供可操作的见解。

Urban logistics solutions have gained paramount significance owing to the rapid growth in concerns about urban areas today. Urban consolidation centres are one of the most attractive and promising solutions for urban logistics, thanks to their numerous critical benefits, including reducing the frequency of transportation, decreasing the number of trucks used, optimizing deliveries, and mitigating the adverse effects of transportation in urban areas. The installation in their optimal positions enables the highest contribution to be made from them, which is a critical factor for their future success. This study aims to enhance sustainability in the supply chain, promote urban welfare in Istanbul, and achieve Turkey's urban logistics goals by providing two distinct location selection suggestions for the European and Anatolian sides of the city. Accordingly, the problem was solved with a triple-staged approach. The first approach is based on stakeholder viewpoints, utilizing the Analytical Hierarchy Process method with 34 stakeholder participants. The second approach is based on traffic counts and uses the Centre of Gravity. The last one is based on a questionnaire completed by 526 participants, encompassing the views of logistics and supply chain managers and scholars. Utilization of a triple-staged approach enables a technical novelty and provides an elaborate consideration of the problem. The study also notably differs from existing studies by including suitability for parking, a critical issue for reducing driver fatigue and protecting employees and thereby making a significant contribution to social sustainability in the supply chain.

由于今天对城市地区的关注迅速增长，城市物流解决方案具有至关重要的意义。城市整合中心是城市物流最具吸引力和前景的解决方案之一，因为它有许多关键的好处，包括减少运输频率、减少使用的卡车数量、优化交付，以及减轻城市地区运输的不利影响。将它们安装在最佳位置可以使它们发挥最大的作用，这是它们未来成功的关键因素。本研究旨在通过为伊斯坦布尔的欧洲和安纳托利亚地区提供两种不同的选址建议，提高供应链的可持续性，促进伊斯坦布尔的城市福利，并实现土耳其的城市物流目标。因此，用三阶段方法解决了这个问题。第一种方法是基于利益相关者的观点，利用层次分析法与34个利益相关者参与者。第二种方法是基于流量计数并使用重心。最后一个是基于526名参与者完成的问卷调查，包括物流和供应链管理人员和学者的观点。使用三阶段方法可以实现技术上的新颖性，并提供对问题的详细考虑。该研究还与现有研究明显不同，包括停车的适宜性，这是减少驾驶员疲劳和保护员工的关键问题，从而为供应链的社会可持续性做出重大贡献。

This study examines how digitalisation and energy structure affect logistics eco-efficiency (LECO), a critical metric for balancing economic and environmental goals in the logistics sector. Using balanced panel data from 36 OECD countries (2008–2020), the analysis employs the Super-SBM-Undesirable model, Tobit regression, and the Method of Moments Quantile regression. Results reveal that digitalisation and renewable energy significantly enhance LECO, while non-renewable energy has a detrimental effect. Notably, digitalisation plays an important moderating role in the energy–LECO relationship. At moderate digital maturity, the benefits of renewable energy are amplified; however, higher digital intensity triggers a rebound effect, diminishing or even reversing these gains. Conversely, digital advancement mitigates the negative impact of non-renewable energy. These insights suggest that policymakers prioritise investments in digital infrastructure and sector-specific applications to enhance logistics eco-efficiency. More importantly, they should align digital transformation strategies with environmental goals to fully leverage the moderating role of digitalisation in energy–LECO interactions.

本研究探讨了数字化和能源结构如何影响物流生态效率（LECO），这是平衡物流业经济和环境目标的关键指标。利用来自36个经合组织国家（2008-2020年）的平衡面板数据，该分析采用了Super-SBM-Undesirable模型、Tobit回归和矩量分位数回归方法。结果表明，数字化和可再生能源显著提高了LECO，而非可再生能源对LECO有不利影响。值得注意的是，数字化在能源- leco关系中起着重要的调节作用。在数字化适度成熟时，可再生能源的好处被放大；然而，更高的数字强度会引发反弹效应，减少甚至逆转这些增益。相反，数字进步减轻了不可再生能源的负面影响。这些见解表明，政策制定者应优先考虑对数字基础设施和特定行业应用的投资，以提高物流生态效率。更重要的是，他们应该将数字化转型战略与环境目标结合起来，充分利用数字化在能源- leco互动中的调节作用。

More importantly, they should align digital transformation strategies with environmental goals to fully leverage the moderating role of digitalisation in energy–LECO interactions.</div></div>","PeriodicalId":47810,"journal":{"name":"Research in Transportation Economics","volume":"114 ","pages":"Article 101665"},"PeriodicalIF":3.4,"publicationDate":"2025-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145474484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sex category and gender-related constructs have been associated with driving-related outcomes and behavioural differences. This study investigated three research objectives: (1) the differences in the perceived frequency of driving behaviours between sex categories and countries; (2) the differences in the gender stereotypes while driving between sex categories and countries; and (3) the mediating role of awareness and endorsement of gender stereotypes in the relationship between gender roles and the perceived frequency of driving behaviours in Türkiye and France. Data were collected from 901 participants (486 from Türkiye and 415 from France). Results revealed significant cross-country differences, with participants from Türkiye generally being more aware and endorsing stereotypes, whereas participants from France associated this to a lesser degree. In both countries, a higher degree of femininity was associated with higher awareness of stereotypes concerning women drivers. This association was subsequently linked to a greater endorsement of gender stereotypes for women drivers and to more favourable perceptions of women's driving behaviour (i.e., higher positive behaviours and lower aberrant behaviours). These findings highlight the association of both individual and country differences on driving perceptions, suggesting that stereotype-driven biases in driving behaviour perceptions may contribute to gender-based inequalities in road safety.

性别类别和与性别相关的构念与驾驶相关的结果和行为差异有关。本研究调查了三个研究目标：(1)不同性别类别和国家之间驾驶行为感知频率的差异；(2)不同性别类别和不同国家间驾驶时的性别刻板印象差异；(3)性别刻板印象的认知和认可在性别角色与驾驶行为感知频率之间的关系中的中介作用（土耳其和法国）。数据收集自901名参与者（486名来自日本，415名来自法国）。结果显示了显著的跨国差异，来自冰岛的参与者通常更意识到并支持刻板印象，而来自法国的参与者在这方面的联系程度较低。在这两个国家，女性化程度越高，对女性司机的刻板印象就越清楚。这种关联随后与对女性司机的性别刻板印象的更多认可以及对女性驾驶行为的更有利的看法（即，更多的积极行为和更少的异常行为）联系在一起。这些发现突出了个人和国家差异与驾驶观念的关联，表明驾驶行为观念中由陈规定型观念驱动的偏见可能导致道路安全方面基于性别的不平等。

This paper uses a Brazilian dataset to estimate the relationship between fuel usage and speed for jet passenger aircraft. This exercise appears to be unique, with prior evidence on the fuel-speed relationship coming entirely from engineering models. The regressions generate U-shaped fuel-speed curves like those from the engineering approach, focusing on groups of narrow-body aircraft types (NEO vs. pre-NEO), rather than individual aircraft models. The empirical estimates are used to evaluate the desirability of environmental aircraft speed limits, which would force planes to fly at a speed that minimizes fuel usage, thereby reducing carbon emissions but imposing longer flight times on passengers.

本文使用巴西的数据集来估计喷气式客机的燃料使用和速度之间的关系。这项实验似乎是独一无二的，之前关于燃油速度关系的证据完全来自工程模型。这些回归会产生u形的燃油速度曲线，就像工程方法那样，重点关注窄体飞机类型（NEO与pre-NEO），而不是单个飞机模型。经验估计用于评估环保型飞机速度限制的可取性，这将迫使飞机以最大限度地减少燃料使用的速度飞行，从而减少碳排放，但给乘客带来更长的飞行时间。

We explore how hierarchical interventions change people's decisions to postpone or cancel travel, comparing the effects of different travel characteristics and external risks. Three travel scenarios (daily grocery shopping, going to a restaurant, and attending a one-off sports match) are considered under three types of travel hindrance (pandemic, heavy rain and traffic congestion). A survey conducted in Japan, Germany and the UK reveals the following results. First, half of the respondents postpone or cancel travel only with a provision of risk information. Second, more than half of the respondents who would not postpone travel with risk information alone change their minds if economic compensation is offered. Third, the minimum discount rate, applied for a future visit, that would change the current behaviour lies within the reasonable range, about 20–40 %. The required discount rate for cancelling is higher than that for postponing. Fourth, when compensation is offered, people postpone or cancel travel if they prioritise for finishing things quickly, are concerned about environmental issues or evaluation by others, feel hassled when cycling or driving a car, or have an attitude of avoiding situational risk.

我们探讨了等级干预如何改变人们推迟或取消旅行的决定，比较了不同旅行特征和外部风险的影响。在3种旅行障碍类型（大流行、暴雨、交通堵塞）下，考虑了3种旅行场景（日常购物、外出就餐、观看一次性体育比赛）。在日本、德国和英国进行的一项调查显示了以下结果。首先，半数受访者只有在获知风险信息后才会推迟或取消旅行。其次，超过一半的受访者表示，如果提供经济补偿，他们会改变主意，而不仅仅是风险信息。第三，为将来的访问申请，将改变当前行为的最低折扣率在合理范围内，约为20 - 40%。取消所需的贴现率高于延期。第四，在获得补偿后，如果人们优先考虑尽快完成任务，担心环境问题或他人的评价，在骑车或开车时感到烦恼，或者有避免情境风险的态度，人们会推迟或取消旅行。
