The increase in motorization creates an urgent need to improve traffic congestion management techniques in urban areas. In this context, network-level control approaches are gaining prominence, and the Macroscopic Fundamental Diagram (MFD) aggregated modeling paradigm is frequently used as a fast and reliable tool to monitor city congestion levels, particularly when the city is divided into regions, each with its own MFD curve. This paper proposes and tests a hierarchical control scheme to implement a city-level Route Guidance strategy. At the upper level, Model Predictive Control (MPC) is used to determine the optimal split ratios between regions, while at the lower level, an actuation system spreads control signals to drivers by simulating Variable Message Signs on the infrastructure. The objective of this paper is to investigate and validate the robustness of this approach. The framework is tested in a complex and realistic traffic scenario representing the entire city of Luxembourg, considering various operating conditions (e.g., parameter settings, fluctuations in travel demand), behavioral factors (e.g., drivers’ compliance) and performance indicators (e.g., system effects on both controlled and uncontrolled zones). Our results show that the control method effectively utilizes the network’s capacity, even with low driver compliance, and drives the entire network to the saturation regime, where optimal throughput is achieved.

由于机动化的增加，迫切需要改进城市地区的交通拥挤管理技术。在这种背景下，网络级控制方法日益突出，宏观基本图（MFD）聚合建模范式经常被用作监测城市拥堵水平的快速可靠工具，特别是当城市被划分为多个区域时，每个区域都有自己的MFD曲线。本文提出并测试了一种实现城市级路径引导策略的分层控制方案。在上层，模型预测控制（MPC）用于确定区域之间的最佳分割比率，而在下层，驱动系统通过模拟基础设施上的可变消息标志将控制信号传递给驾驶员。本文的目的是研究和验证这种方法的鲁棒性。该框架在代表整个卢森堡市的复杂而现实的交通场景中进行了测试，考虑了各种操作条件（例如，参数设置、出行需求波动）、行为因素（例如，驾驶员的合规性）和性能指标（例如，系统对受控和非受控区域的影响）。我们的结果表明，该控制方法有效地利用了网络的容量，即使在低驱动器遵从性的情况下，也能将整个网络驱动到饱和状态，从而实现最佳吞吐量。

Meta-analyses are an important source of road safety evidence. However, their source data may be biased by both evaluation quality and journal quality. This motivated us to explore the link, focusing on the effectiveness of physical road safety measures. We collected and combined two kinds of datasets: evaluation quality of research (seven samples) and journal quality (eight ranking lists). In the end, only the CMF Clearinghouse dataset of more than 1000 evaluations could be used. Despite some inconsistencies, six of eight rankings showed the expected positive relationship: the better journal ranking, the better evaluation ranking (and vice versa). This calls for the attention of authors and readers, as well as meta-analysts, particularly in the context of predatory journals and their potential impacts on the quality of road safety meta-analyses.

元分析是道路安全证据的重要来源。然而，他们的源数据可能会受到评价质量和期刊质量的影响。这促使我们探索这种联系，重点关注道路物理安全措施的有效性。我们收集并合并了两类数据集：研究评价质量（7个样本）和期刊质量（8个排名列表）。最后，只能使用CMF Clearinghouse超过1000个评价的数据集。尽管存在一些不一致，但8个排名中有6个显示出预期的正相关关系：期刊排名越高，评价排名越高（反之亦然）。这需要作者和读者以及元分析人员的注意，特别是在掠夺性期刊及其对道路安全元分析质量的潜在影响的背景下。

Commuting time is closely associated with both life dissatisfaction and obesity, particularly for working women with childcare responsibilities. This study uses childcare time as an indicator of childcare intensity to examine how commuting time and childcare intensity are related to women’s life dissatisfaction and obesity. Using data from the China Health and Nutrition Survey (2006, 2009, 2011, and 2015), this study employs an ordered probit model, a binary probit model, and a generalized additive model (GAM). After controlling for year, region, age, income, education, marital status, travel mode, and time use, we systematically explore the relationships between commuting time, childcare intensity, life dissatisfaction, and obesity. The ordered probit model reveals a significant inverted “U” shaped relationship between commuting time and women’s life dissatisfaction, peaking at around 90 min. GAM robustness checks show minimal correlation below 30 min, a rising trend between 30 and 90 min, and a decline thereafter. Among women who spend less than 20 h per week on childcare, the turning point in the inverted “U” shaped relationship with life dissatisfaction is delayed to 106 min, while the relationship between commuting time and obesity is significantly positive and linear. Moreover, the associations between commuting time, life dissatisfaction, and obesity are particularly pronounced among women employed in non-state-owned enterprises, public transportation users, and those residing in urban. The study provides insights into understanding the commuting-stress-health nexus, highlighting the significant influence of gender-specific roles in the workplace and home.

通勤时间与生活不满和肥胖密切相关，尤其是对有育儿责任的职业女性而言。本研究以育儿时间作为育儿强度的指标，考察通勤时间和育儿强度与女性生活不满和肥胖的关系。利用中国健康与营养调查（2006年、2009年、2011年和2015年）的数据，本研究采用有序probit模型、二元probit模型和广义加性模型（GAM）。在控制了年份、地区、年龄、收入、受教育程度、婚姻状况、出行方式和时间利用等因素后，我们系统地探讨了通勤时间、育儿强度、生活不满和肥胖之间的关系。有序概率模型显示通勤时间与女性生活不满之间存在显著的倒“U”型关系，在90分钟左右达到峰值。GAM稳健性检查显示，30分钟以下相关性最小，30至90分钟之间呈上升趋势，此后呈下降趋势。在每周花在育儿上的时间少于20小时的女性中，与生活不满的倒“U”型关系的拐点延迟到106分钟，而通勤时间与肥胖之间的关系呈显著的正线性关系。此外，通勤时间、生活不满和肥胖之间的关联在非国有企业就业妇女、公共交通使用者和居住在城市的妇女中尤为明显。这项研究为理解通勤压力与健康之间的关系提供了见解，强调了工作场所和家庭中特定性别角色的重大影响。

A cross-methodological review on the safety effects of partial vehicle automation 部分车辆自动化对安全影响的跨方法回顾

We present a cross-methodological review on the safety implications of Partially Automated Vehicles (PAV). We inventory theoretical considerations on possible safety effects, and evaluate results from computer simulations, driving simulators, Experimental Driving Studies (EDS), Naturalistic Driving Studies (NDS), and real-world crash data (censuses), to gain insight in detrimental and beneficial safety effects of partial automation.

Theoretical concerns center around incompatibility between the requirement of constant supervision and the potential for increased distraction, reduced vigilance, mode confusion and dis- and misuse, alongside technological limitations such as system reliability outside the Operational Design Domain (ODD). Computer simulations show mixed results, and suggest that benefits of automation may emerge only at higher levels of automation. Simulator studies, EDS and NDS support concerns about a detrimental impact of automation on human drivers, although beneficial effects on Surrogate Safety Measures (SSM), reflecting smoother driver behavior are also reported. These results are uncertain, due to limited generalizability of simulator studies and SSM. Census data indicate reduced crash rates but do not reveal causality.

Detrimental effects on the human driver are a consistent finding across several methodologies, but studies adopting methodologies with higher representativeness nuance these findings, showing net safety benefits. Although automation may mitigate some theoretical concerns by relaxing requirements on the human driver, alternative explanations relating to confounding factors, such as the presence of dedicated safety systems, cannot be excluded.

The findings emphasize the need for real-world validations, refinement of Human–Machine Interfaces (HMIs), and strategies to address fleet heterogeneity. This review underscores the critical role of integrated evidence in shaping policies for safer adoption of PAV technologies.

我们提出了对部分自动驾驶汽车（PAV）的安全影响的跨方法综述。我们列出了可能的安全影响的理论考虑，并评估了计算机模拟、驾驶模拟器、实验驾驶研究（EDS）、自然驾驶研究（NDS）和现实世界碰撞数据（普查）的结果，以深入了解部分自动化的有害和有益的安全影响。理论关注的焦点是持续监督的要求与增加分心、降低警惕性、模式混淆和滥用的可能性之间的不兼容性，以及技术限制，如操作设计域（ODD）之外的系统可靠性。计算机模拟显示了不同的结果，并表明自动化的好处可能只有在更高的自动化水平上才会出现。模拟器研究、EDS和NDS都支持了对自动化对人类驾驶员不利影响的担忧，尽管也报道了对替代安全措施（SSM）的有益影响，反映了驾驶员更平稳的行为。由于模拟器研究和SSM的推广能力有限，这些结果是不确定的。人口普查数据显示撞车率下降，但没有揭示因果关系。对人类驾驶员的有害影响是几种方法的一致发现，但采用具有更高代表性的方法的研究对这些发现进行了细微差别，显示出净安全效益。虽然自动化可以通过放松对人类驾驶员的要求来减轻一些理论上的担忧，但不能排除与混杂因素有关的其他解释，例如专用安全系统的存在。研究结果强调了对实际验证、人机界面（hmi）的改进以及解决车队异质性的策略的需求。这一综述强调了综合证据在制定更安全地采用PAV技术的政策方面的关键作用。

States and their respective national civil aviation authorities promote improvements to the global civil aviation system by enacting and enforcing safety regulations for aircraft design, operations, personnel training, infrastructure, and air traffic management, among others. Weak safety oversight systems can have significant social and economic implications, but local factors may affect their implementation capability. ICAO has driven the continuous development of states’ safety oversight functions, supporting them in evaluating the effectiveness of these functions by conducting audits under the USOAP program. While the benefits of these assessments have been widely recognized, the scholarly literature on the factors commonly associated with safety oversight effectiveness across states is limited. This study connects public governance theory with aviation state safety oversight, proposing a framework that links macro-level public-service capacity to sector-specific regulator performance. The theoretical framework is tested quantitatively by applying metrics collected by the Worldwide Governance Indicators, specifically Government Effectiveness (GE) and Regulatory Quality (RQ), as well as the ICAO safety oversight audits’ Effective Implementation (EI) metric. The research design combines confirmatory factor analysis and covariance-based structural equation modeling to validate the latent governance constructs and estimate their effects on EI. Results supported the proposed framework, which links broader dimensions of governance and aviation safety oversight, particularly between GE and EI. Theoretically, the results support the factorial validity of GE and RQ as well as the proposed governance–oversight framework. Recommendations are presented for aviation safety oversight organizations to consider governance measures in safety oversight assessment mechanisms and to promote additional research on the factors associated with oversight effectiveness.

各国及其各自的国家民用航空主管部门通过制定和执行飞机设计、操作、人员培训、基础设施和空中交通管理等方面的安全法规，促进改善全球民用航空系统。薄弱的安全监督系统可能会产生重大的社会和经济影响，但当地因素可能会影响其实施能力。国际民航组织推动了各州安全监督职能的不断发展，通过在USOAP计划下开展审计，支持各州评估这些职能的有效性。虽然这些评估的好处已得到广泛认可，但关于各州安全监督有效性的普遍相关因素的学术文献有限。本研究将公共治理理论与航空国家安全监管联系起来，提出了一个将宏观层面的公共服务能力与特定部门监管机构绩效联系起来的框架。理论框架通过应用全球治理指标收集的指标进行定量测试，特别是政府有效性（GE）和监管质量（RQ），以及国际民航组织安全监督审计的有效实施（EI）指标。研究设计结合验证性因子分析和基于协方差的结构方程模型来验证潜在的治理结构，并估计其对EI的影响。结果支持提议的框架，该框架将治理和航空安全监督的更广泛维度联系起来，特别是在通用电气和EI之间。从理论上讲，结果支持GE和RQ的析因有效性以及所提出的治理-监督框架。建议航空安全监督组织考虑在安全监督评估机制中采取治理措施，并促进对与监督有效性有关的因素进行进一步研究。

This study examines the short-term effects of a sudden fuel price increase on urban public transit and interurban private car travel demand in Iran, where fuel prices are regulated. Using log–log regression models, we estimate elasticities to quantify the relationship between fuel price and travel demand, controlling for weekends, holidays, seasonal variations, and special events. In the urban section, Automated Fare Collection (AFC) data from the subway and Bus Rapid Transit (BRT) systems in Tehran is utilized. For the first time in this context, the Trip-Chaining Method (TCM) is applied to AFC transactions to derive daily origin–destination matrices, enabling calculation of mode-specific demand and Passenger-Kilometers Traveled (PKT). The estimated cross-price elasticities are 0.10 for the subway and 0.079 for the BRT, while aggregate public transit demand measured in PKT shows an elasticity of 0.098. For the interurban analysis, traffic loop detector data are used, with daily Vehicle-Kilometers Traveled (VKT) as the dependent variable. The direct elasticity of VKT with respect to fuel price is −0.19, indicating that a 1 % increase in fuel price reduces interurban travel demand by 0.19 %. These elasticities closely align with international evidence from variable-price contexts, remaining below unity. Additionally, a Difference-in-Differences (DID) analysis confirms the impact of the fuel price shock: transit ridership increased by about 6–9 %, while interurban VKT decreased by around 14 % shortly after the reform. Overall, the findings offer new evidence from a heavily subsidized fuel market and contribute to understanding how travelers adjust to major fuel price reforms.

本研究考察了燃油价格突然上涨对伊朗城市公共交通和城市间私家车出行需求的短期影响。使用对数-对数回归模型，我们估计弹性来量化燃料价格和旅行需求之间的关系，控制周末，假期，季节变化和特殊事件。在城市部分，利用了德黑兰地铁和快速公交系统的自动收费（AFC）数据。在这种情况下，首次将行程链方法（TCM）应用于AFC交易，以获得每日出发地-目的地矩阵，从而能够计算特定模式的需求和乘客-公里数（PKT）。地铁的估计交叉价格弹性为0.10，BRT的估计交叉价格弹性为0.079，而PKT测量的公共交通总需求弹性为0.098。对于城际分析，使用交通环路探测器数据，以每日车辆行驶公里（VKT）为因变量。VKT相对于燃料价格的直接弹性为- 0.19，表明燃料价格每上涨1%，城市间旅行需求就会减少0.19%。这些弹性与来自可变价格背景的国际证据密切一致，仍低于统一水平。此外，一项差异中的差异（DID）分析证实了燃油价格冲击的影响：在改革后不久，公共交通客流量增加了约6 - 9%，而城际交通客流量下降了约14%。总的来说，研究结果提供了大量补贴燃料市场的新证据，有助于了解旅行者如何适应重大的燃料价格改革。

This research presents a detailed investigation of the materials used in the construction of the roads of the ancient city of Pompeii, focusing in particular on the paving of the Via del Foro. Through excavation and laboratory analysis, the study aims to characterize the granular composition and mechanical properties of these materials. Excavation revealed stratigraphic layers composed of various materials, including limestone, volcanic rock, and ceramic fragments. Samples collected from these layers underwent comprehensive laboratory testing, including grading, shape index, flakiness index, water absorption, Los Angeles abrasion, and durability assessments. The results indicate variations in particle size distribution, shape characteristics, water absorption capacities, resistance to fragmentation, and durability among the samples. Furthermore, the study uses Building Information Modeling (BIM) to digitally reconstruct the excavation site and simulate excavation phases, illustrating the potential of BIM in archaeological conservation efforts. These findings provide valuable insights into ancient Roman road construction techniques, material selection practices, and preservation strategies, linking archaeology, engineering, and digital technologies to enhance our understanding and management of cultural heritage sites.

本研究对庞贝古城道路建设中使用的材料进行了详细的调查，特别关注了Foro大道的铺设。通过挖掘和实验室分析，研究旨在表征这些材料的颗粒组成和力学性能。挖掘揭示了由各种材料组成的地层，包括石灰石、火山岩和陶瓷碎片。从这些层中收集的样品进行了全面的实验室测试，包括分级、形状指数、片状指数、吸水率、洛杉矶磨损和耐久性评估。结果表明，不同样品在粒径分布、形状特征、吸水能力、抗破碎性和耐久性方面存在差异。此外，该研究使用建筑信息模型（BIM）对挖掘现场进行数字化重建，并模拟挖掘阶段，说明了BIM在考古保护工作中的潜力。这些发现为古罗马道路建设技术、材料选择实践和保护策略提供了有价值的见解，将考古学、工程学和数字技术联系起来，以增强我们对文化遗产遗址的理解和管理。

Through excavation and laboratory analysis, the study aims to characterize the granular composition and mechanical properties of these materials. Excavation revealed stratigraphic layers composed of various materials, including limestone, volcanic rock, and ceramic fragments. Samples collected from these layers underwent comprehensive laboratory testing, including grading, shape index, flakiness index, water absorption, Los Angeles abrasion, and durability assessments. The results indicate variations in particle size distribution, shape characteristics, water absorption capacities, resistance to fragmentation, and durability among the samples. Furthermore, the study uses Building Information Modeling (BIM) to digitally reconstruct the excavation site and simulate excavation phases, illustrating the potential of BIM in archaeological conservation efforts. These findings provide valuable insights into ancient Roman road construction techniques, material selection practices, and preservation strategies, linking archaeology, engineering, and digital technologies to enhance our understanding and management of cultural heritage sites.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"36 ","pages":"Article 101830"},"PeriodicalIF":3.8,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145897986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
