High-Speed Rail (HSR) projects such as the local East Coast Rail Link (ECRL) are development projects that are very meaningful to the well-being of the community between the east coast and the west coast of the Malaysian peninsula. To study the actual achievement of environmental performance from this project, researchers need to identify the level of involvement and interaction networks of actors in managing environmental issues and problems during the construction phase. The lack of accurate data for the construction phase compared to the operation phase is still underexplored, which has prompted this research to include the Social Network Analysis (SNA) method in an effort to answer a research question, namely: does the social network among stakeholders serve as a channel for transferring information related to environmental issues in the Besut Railway Project in Terengganu? This study employs a qualitative approach, utilizing observation and interviews with 25 respondents. The data collected were analyzed using UCINET version 6.7 software. The findings indicate that the train developer contractor exhibited a greater level of engagement in addressing environmental issues compared to other stakeholders. This is supported by the values of the level center and betweenness. Additionally, the study recommends several measures to tackle environmental challenges associated with railway projects, including conducting comprehensive environmental impact assessments (EIA) and social impact assessments (SIA), engaging stakeholders in the decision-making process regarding environmental concerns, and enhancing public awareness of these issues. In conclusion, addressing the environmental problems arising from railway projects necessitates collaboration among all parties. The public should not leave this responsibility solely to contractors; through community participation, environmental issues can be minimized, leading to more effective implementation of local railway projects.

高速铁路（HSR）项目，如当地的东海岸铁路线（ECRL），是对马来西亚半岛东海岸和西海岸之间社区的福祉非常有意义的发展项目。为了研究该项目环境绩效的实际成果，研究人员需要确定参与者在建设阶段管理环境问题和问题的参与程度和互动网络。与运营阶段相比，建设阶段缺乏准确的数据仍未得到充分的探讨，这促使本研究采用社会网络分析（SNA）方法来回答一个研究问题，即：在登嘉楼Besut铁路项目中，利益相关者之间的社会网络是否作为传递与环境问题相关信息的渠道？本研究采用定性方法，利用观察和访谈25名受访者。采用UCINET 6.7版软件对收集的数据进行分析。研究结果表明，与其他利益相关者相比，火车开发商承包商在解决环境问题方面表现出更大的参与度。这是由level center和betweness的值支持的。此外，该研究还建议采取几项措施来应对与铁路项目有关的环境挑战，包括开展全面的环境影响评估（EIA）和社会影响评估（SIA），让利益相关者参与环境问题的决策过程，以及提高公众对这些问题的认识。总之，解决铁路项目产生的环境问题需要各方的合作。公众不应将这一责任完全推给承包商；通过社区参与，可以最大限度地减少环境问题，从而更有效地实施地方铁路项目。

Aligned with sustainable development goals (SDGs) and European Union policy goals, including the Green Deal, this study examines the integration of low-emission zones (LEZs) with rail logistics to enhance sustainable urban freight transport. While existing research focuses on standalone LEZs policies for passenger vehicles, the role of rail in freight decarbonization has been underexplored. The study develops a dynamic simulation model to compare the policies of only LEZs, LEZs + Rail, and LEZs + Multimodal, to assess their impact on emissions and logistics efficiency, focusing on achieving the SDGs. A case study from the European logistics sector was conducted in Rotterdam, The Netherlands. To ensure robustness of the simulation, the freight data and emission factors for validating the model were adopted from the Covenant-Zero-Emission-City-Logistics-Rotterdam and STREAM report for freight transport (CE Delft). This study is structured into four phases. The first phase involves data collection, system characterization, input of the simulation model, and assumption validation. The second phase is emission estimation using the Groot-Rijnmond model. The third phase includes the formulation of the dynamic simulation model. Finally, the fourth phase involves the development of scenarios and the testing of policies. The results highlight the potential of the LEZs–rail synergy to enhance the efficiency of the last mile logistics and significantly reduce transportation-related emissions in dense urban settings. The findings indicate that dynamic access pricing and multimodal logistics hubs facilitate a 55 percent shift toward rail freight, improving economic efficiency and resilience to supply chains. Furthermore, while a fixed congestion charge reduces freight emissions approximately 20 percent by 2030, a fully optimized dynamic pricing + rail strategy achieves a 50–55 percent reduction. Sensitivity analysis confirms the robustness of the results, demonstrating the applicability of the model to complex and dynamic decision-making contexts. This study offers theoretical contributions and practical insights for decision makers looking to improve the sustainability of urban logistics while ensuring economic viability and operational efficiency.

根据可持续发展目标（sdg）和欧盟政策目标（包括绿色协议），本研究探讨了低排放区（LEZs）与铁路物流的整合，以加强可持续的城市货运。虽然现有的研究主要集中在客运车辆的独立低碳区政策上，但铁路在货运脱碳中的作用尚未得到充分探讨。该研究开发了一个动态仿真模型，以比较仅限lez、lez + Rail和lez + Multimodal的政策，以评估其对排放和物流效率的影响，重点是实现可持续发展目标。在荷兰鹿特丹进行了欧洲物流部门的案例研究。为了确保模拟的鲁棒性，用于验证模型的货运数据和排放因子采用了公约-零排放城市-物流-鹿特丹和货运STREAM报告（CE Delft）。本研究分为四个阶段。第一阶段包括数据收集、系统表征、仿真模型输入和假设验证。第二阶段是使用Groot-Rijnmond模型进行排放估计。第三阶段包括动态仿真模型的建立。最后，第四个阶段涉及场景的开发和政策的测试。研究结果强调了低污染区与铁路协同作用的潜力，可以提高最后一英里物流的效率，并显著减少人口密集城市环境中与运输相关的排放。研究结果表明，动态准入定价和多式联运物流中心促进了55%的铁路货运转移，提高了经济效率和供应链弹性。此外，到2030年，固定的拥堵费可以减少约20%的货运排放，而完全优化的动态定价+铁路战略可以减少50 - 55%的排放。敏感性分析证实了结果的稳健性，表明该模型适用于复杂和动态的决策环境。本研究为决策者在确保经济可行性和运营效率的同时提高城市物流的可持续性提供了理论贡献和实践见解。

Metro systems play a key role in supporting sustainable urban transportation; therefore, understanding how passengers evaluate their service quality is essential. The objective of the current study is to investigate the key factors influencing passenger satisfaction using the Q method. Participants ranked 34 service-related items through a drag-and-drop interface of an online Q-sorting questionnaire. The resulting Q-distribution data, extracted from 34 valid Q-sorts, were examined using principal component analysis with Varimax rotation, revealing seven distinct group viewpoints. The findings show that “accessibility to stations and destinations”, “punctuality”, as the first to second ranks; as well as “travel speed” and “accessibility to various parts of the city”, together as the third rank, respectively, consistently appear as the most influential elements across groups. In contrast, factors such as extended train door-opening times and staff effort in resolving complaints were considered less important. The insights show which service features most affect perceived quality and offer practical advice on how to improve the metro system performance.

地铁系统在支持可持续城市交通方面发挥着关键作用；因此，了解乘客如何评价他们的服务质量是至关重要的。本研究的目的是使用Q方法来调查影响乘客满意度的关键因素。参与者通过在线q排序问卷的拖放界面对34个与服务相关的项目进行排名。从34种有效的q分类中提取的q分布数据，使用主成分分析和Varimax旋转进行了检查，揭示了7种不同的群体观点。调查结果显示，“到达车站和目的地的可达性”、“准点率”为第一至第二名；“出行速度”和“可达性”分别排在第三位，在各群体中始终是最具影响力的因素。相比之下，延长列车开门时间和工作人员解决投诉的努力等因素被认为不那么重要。这些见解显示了哪些服务特征最能影响感知质量，并就如何改善地铁系统性能提供了实用的建议。

Following the global shift towards Electric Vehicles (EVs) from conventional vehicles, Nepal has been marching towards development of charging infrastructures and promotion of EVs. Department of Transport Management (DoTM) shows that share of diesel import is on the higher side, and it is important to consider electrification of diesel-based transportation systems with higher priority. This study develops real-world driving cycle of a public bus considering the urban environment of Kathmandu Valley. A route is selected to incorporate major business centers of the valley. Global Positioning System (GPS) logger is used for data collection for a period of 3 months at 1 Hz. Gradient is determined using Geographic Information System (GIS) software, Open Street Map (OSM) and Shuttle Radar Topography Mission (SRTM) data sources. 18 assessment parameters are selected for cycle assessment. 80% data set undergoes Markov Chain and Monte Carlo simulation to construct candidate driving cycles. An energy consumption model developed in MATLAB Simulink is used to compare energy consumption. A candidate driving cycle of 1200s with 10.39% Mean Absolute Percentage Error (MAPE) and Root Mean Square Error (RMSE) of 1.82% is chosen as the final driving cycle. Comparison with other standard driving cycles revealed that Kathmandu Driving Cycle is around 22–36% more demanding. Further, not considering the gradient underestimates the energy consumption by 45.85%. This study, thus, highlights significance of real-world driving cycle construction considering local environment for appropriate energy management strategy, powertrain sizing and infrastructural development.

随着全球从传统汽车转向电动汽车（ev），尼泊尔一直在朝着充电基础设施的发展和电动汽车的推广迈进。交通管理部门（DoTM）显示，柴油进口份额偏高，重要的是要优先考虑柴油运输系统的电气化。本研究以加德满都谷地的都市环境为背景，开发了公共巴士的真实驾驶循环。选择一条路线，将山谷的主要商业中心纳入其中。GPS （Global Positioning System，全球定位系统）记录仪以1hz频率采集数据，采集周期为3个月。利用地理信息系统（GIS）软件、开放街道地图（OSM）和航天飞机雷达地形任务（SRTM）数据源确定梯度。选取18个评估参数进行周期评估。80%的数据集通过马尔可夫链和蒙特卡罗模拟来构建候选驾驶循环。利用MATLAB Simulink开发的能耗模型对能耗进行比较。最终选择1200秒的候选驾驶周期，平均绝对百分比误差（MAPE）为10.39%，均方根误差（RMSE）为1.82%。与其他标准驾驶周期相比，加德满都驾驶周期的要求约为22-36%。此外，不考虑梯度，低估了45.85%的能耗。因此，本研究强调了考虑当地环境的真实驾驶循环构建对于适当的能源管理策略，动力总成尺寸和基础设施发展的重要性。

This study aimed to investigate teachers’ driving behavior and analyze the relationship between their attitudes based on the Health Belief Model (HBM) and driving behavior in Nakhon Ratchasima Province, Thailand. The sample consisted of 800 secondary school teachers. Factor analysis and structural equation modeling (SEM) were employed for data analysis. The measurement model demonstrated acceptable fit indices (RMSEA = 0.063, CFI = 0.916, TLI = 0.907, SRMR = 0.062). The SEM results revealed that health motivation (β = −0.127, p < 0.05) and perceived severity, benefit and cue (β = −0.144, p < 0.05) significantly reduced risky driving behavior, whereas perceived barriers increased risky behavior (β = 0.315, p < 0.001). These findings suggest that road safety interventions for teachers should focus on reducing perceived barriers, enhancing perceived susceptibility, benefits and cues to action, and strengthening health motivation. The results provide practical guidelines for developing policy recommendations and safety measures targeting teachers.

本研究旨在调查泰国那空叻差玛省教师的驾驶行为，并基于健康信念模型（HBM）分析其态度与驾驶行为的关系。样本包括800名中学教师。采用因子分析和结构方程模型（SEM）对数据进行分析。测量模型具有可接受的拟合指标（RMSEA = 0.063, CFI = 0.916, TLI = 0.907, SRMR = 0.062）。扫描电镜结果显示，健康动机（β = - 0.127, p < 0.05）和感知严重性、利益和提示（β = - 0.144, p < 0.05）显著降低危险驾驶行为，感知障碍（β = 0.315, p < 0.001）显著增加危险驾驶行为。这些研究结果表明，教师的道路安全干预应侧重于减少感知障碍，增强感知易感性、利益和行动线索，并加强健康动机。研究结果为制定针对教师的政策建议和安全措施提供了实用指南。

Free Trade-Industrial Zones, with their unique characteristics, can drive regional and national economic growth. However, without aligning with core objectives, they risk becoming import hubs for consumer goods, leading to capital flight and weakening the economy. This study examines the Anzali Free Trade-Industrial Zone’s performance over two decades, analyzing investment, export, and import data through a mixed-methods approach, including library research and interviews with zone administrators.

Findings show a decline in imports, stable exports, and significant growth in locally manufactured goods for international and domestic markets—indicators of increased employment. Yet, regulatory inconsistencies, limited value-added processing, and infrastructure gaps, especially related to the North-South Transport Corridor, pose challenges. To address these issues, attracting targeted investments in processing industries, fostering industrial ecosystems, and strengthening maritime links are crucial. Additionally, leveraging regional strengths by investing in sectors like fisheries and agriculture, improving transportation infrastructure—such as connecting to the national railway—and expanding trade agreements and reducing tariffs could enhance trade volume.

Given its strategic location, the Anzali Zone has the potential to become a major economic hub in northern Iran. Achieving this requires strategic planning, effective regulation, and regional cooperation, which would significantly boost export-led growth and regional development.

自由贸易产业区以其独特的特点，带动了区域和国家经济的发展。然而，如果不与核心目标保持一致，它们就有可能成为消费品的进口中心，导致资本外逃，削弱经济。本研究考察了安扎利自由贸易工业区二十年来的表现，通过混合方法分析了投资、出口和进口数据，包括图书馆研究和对自贸区管理者的访谈。调查结果显示，进口下降，出口稳定，面向国际和国内市场的本地制成品大幅增长，这些都是就业增加的指标。然而，监管不一致、增值加工有限以及基础设施差距，特别是与南北运输走廊相关的基础设施差距，构成了挑战。为解决这些问题，吸引有针对性的加工业投资、培育工业生态系统和加强海上联系至关重要。此外，通过投资渔业和农业等部门、改善交通基础设施（如连接国家铁路）、扩大贸易协定和降低关税来发挥区域优势，可以增加贸易额。鉴于其战略位置，安扎里区有潜力成为伊朗北部的一个主要经济中心。实现这一目标需要战略规划、有效监管和区域合作，这将大大促进出口导向型增长和区域发展。

Faced with chronic traffic congestion and spatial inequities, global megacities urgently need urban air mobility (UAM) integration to enhance transportation resilience and promote equitable mobility. This study constructs a constrained clustering model to identify vertiport locations, considering no-fly zones and integrating passenger flow demand and point of interest (POI) distribution. By constructing a two-layer transport network and employing percolation theory, we systematically evaluate how vertiport deployment strategies impact regional-level resilience and equity. The findings of the Beijing case reveal the relationship between deployment scale and resilience equity. Moderate deployment helps to improve and compensate for regional resilience differences, balance efficiency and fairness, but large-scale deployment exacerbates inequality. This research underscores the importance of strategic and non-uniform vertiport siting to mitigate urban transport disparities, providing theoretical insights and policy recommendations for equitable UAM development.

面对长期的交通拥堵和空间不平等，全球特大城市迫切需要城市空中交通（UAM）一体化，以增强交通弹性，促进交通公平。本文在考虑禁飞区的基础上，结合客流需求和兴趣点分布，构建了一个约束聚类模型来确定垂直机场的位置。通过构建两层运输网络并运用渗透理论，我们系统地评估了垂直机场部署策略如何影响区域层面的弹性和公平性。北京案例的发现揭示了部署规模与弹性公平之间的关系。适度部署有助于改善和弥补区域弹性差异，平衡效率和公平，但大规模部署会加剧不平等。本研究强调了战略性和非统一垂直机场选址对于缓解城市交通差异的重要性，为公平的垂直机场发展提供了理论见解和政策建议。

Effectively designed parking solutions play a crucial role in mitigating urban challenges such as traffic congestion, excessive fuel consumption, and reduced safety. This study integrates GPS data with traveler survey data to model parking choice behavior, including preferences for parking type and choice for specific garage. Given the hierarchical nature of the choices, a nested logit model was estimated within a Bayesian framework using the Metropolis-Hastings algorithm. This approach is particularly efficient for high-dimensional models due to its fast convergence and straightforward implementation. The model was subsequently implemented within an agent-based transportation system simulation tool, POLARIS, to analyze the variations in drivers’ parking choice under diverse parking fee and capacity restriction scenarios. Analysis of the simulated scenarios for the Chicago network representing 8.5 million population revealed that while parking fee adjustments significantly impact travelers’ parking choices, fee variations during peak periods have minimal effect. For instance, a 50% rise in garage fees decreased the number of garage travelers by approximately 20%. However, raising garage fees by the same amount (50%) in the city during peak traffic periods led to a marginal drop of 7% in garage demand. Parking agencies generally set fees on the higher side to increase profit margins. However, parking policies should be designed to balance both travelers’ and transportation agencies’ interests in the long run. In addition, this study shows that allocating a portion of parking spaces to reserved parking or specific vehicle types, for a better curb space and parking management, significantly influences travelers’ decision-making in the parking choice selection.

有效设计的停车解决方案在缓解交通拥堵、过度油耗和安全性降低等城市挑战方面发挥着至关重要的作用。本研究将GPS数据与旅行者调查数据相结合，对停车选择行为进行建模，包括对停车类型的偏好和对特定车库的选择。考虑到选择的层次性，使用Metropolis-Hastings算法在Bayesian框架内估计嵌套logit模型。由于其快速收敛和简单的实现，该方法对高维模型特别有效。该模型随后在基于代理的交通系统仿真工具POLARIS中实施，以分析不同停车收费和容量限制情景下驾驶员停车选择的变化。对代表850万人口的芝加哥网络的模拟情景分析显示，停车费用的调整对旅客的停车选择有显著影响，而高峰时段的费用变化影响最小。例如，车库费上涨50%，车库旅行者的数量减少了大约20%。然而，在交通高峰期将车库费提高50%，导致车库需求小幅下降7%。停车代理机构通常将收费定得较高，以增加利润率。然而，从长远来看，停车政策的设计应该平衡旅客和运输机构的利益。此外，本研究还表明，为了更好地控制路边空间和管理停车，将一部分停车位分配给预留停车位或特定车型，显著影响出行者的停车选择决策。

End-of-life vehicles (ELV) management is crucial for sustainable development in a circular economy and waste minimization for the conservation of natural resources. However, there is still improper connection between the National Automotive Policy (NAP) 2020 implementation and the ELV strategies development in the supply chain of the Malaysian automotive industry. ELV recycling and remanufacturing companies face difficulties adopting appropriate ELV implementation strategies for used parts recovery in ELV. Therefore, this study aims to develop a strategic framework to improve the value chain of ELV in Malaysia. The study adopted qualitative interview approach with a total of nine respondents from six ELV recycling companies as multiple case studies. The three directions identified are optimization of ELV used parts/cores supply and demand, recovery of ELV used parts/cores, and improvement of ELV used parts/cores quality. Nine sub-strategies were proposed to address the corresponding critical enablers (strengths and opportunities) and inhibitors (weaknesses and threats) to improve the ELV value chain. Based on their contextual relevance, these sub-strategies were categorized into two main strategies: 1) value chain development, and 2) human capital and technological development. Lastly, a strategic framework which consists of three key focus directions and two main strategies was developed. The proposed strategic framework serves as a pathway for implementing future ELV policy in Malaysia, in line with NAP 2020. The ELV-related companies, government agencies and industry stakeholders especially in developing countries can adopt this strategic framework to formulate appropriate directions and strategies to optimize their ELV value chain for sustainable development.

报废车辆（ELV）管理对于循环经济的可持续发展和减少废物以保护自然资源至关重要。然而，国家汽车政策（NAP） 2020的实施与马来西亚汽车行业供应链中的ELV战略发展之间仍然存在不适当的联系。ELV回收和再制造企业在采用合适的ELV实施策略进行ELV废旧零部件回收方面面临困难。因此，本研究旨在制定一个战略框架，以改善马来西亚的电动汽车价值链。本研究采用质性访谈法，选取6家ELV回收公司共9名受访者作为多案例研究。确定了三个方向：电气化车废旧件/芯供需优化、电气化车废旧件/芯回收、电气化车废旧件/芯质量提升。提出了9个子战略，以解决相应的关键推动因素（优势和机会）和抑制因素（弱点和威胁），以改善ELV价值链。根据其上下文相关性，将这些子战略分为两个主要战略：1)价值链发展战略和2)人力资本和技术发展战略。最后，制定了由三个重点方向和两个主要战略组成的战略框架。拟议的战略框架是在马来西亚实施未来低成本汽车政策的途径，符合NAP 2020。特别是发展中国家的电动汽车相关企业、政府机构和行业利益相关者可以采用这一战略框架，制定适当的方向和战略，优化其电动汽车价值链，实现可持续发展。
