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.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"23 ","pages":"Article 101697"},"PeriodicalIF":3.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146037373","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}

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.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"23 ","pages":"Article 101720"},"PeriodicalIF":3.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146037376","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}

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 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.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"23 ","pages":"Article 101671"},"PeriodicalIF":3.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145684477","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}

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.
