The limitations of Ca-based treatments have spurred the investigation of geopolymers, yet Na<sub>2</sub>SiO<sub>3</sub> in the alkaline activator compromised the sustainability. In response, a novel waste-derived rice husk ash (RHA)-based silicate solution was introduced for geopolymer-based expansive subgrade stabilization (Slag-RHA-GP), though its environmental sustainability remains unexplored. This study conducts a cradle-to-construction life-cycle assessment of Slag-RHA-GP while comparing results with cement (OPC) and conventional Na<sub>2</sub>SiO<sub>3</sub>-based geopolymer treatment (GP) based on a hypothetical case study. Normalized mid-point impacts indicate that the Slag-RHA-GP binder exhibits ∼ 43 % improved environmental performance compared to GP. RHA-silicate substitution reduces ecosystem impacts by ∼ 79 % at the raw material production stage. Moreover, except for Hg and Se, heavy metal leaching of Slag-RHA-GP remains well below permissible levels. Slag-RHA-GP demonstrated a 31.5 % cost-effectiveness and an overall sustainability advantage of 28.9 % and 6.4 % over conventional GP and OPC, respectively. The findings will support the future adoption of sustainable geopolymer stabilizers for in-situ expansive subgrade treatment, aligning with emission neutrality goals.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"146 ","pages":"Article 104840"},"PeriodicalIF":7.3,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed multi-objective optimization model incorporates technical limitations and user preferences, considering minimum charging current and state-of-charge limits. Additionally, a model for constructing marginal emission factors based on electricity market coupling is developed. Using detailed EV charging data, it assesses long-term optimization effectiveness over three distinct scenarios. Results show the base model achieves up to 24% cost and 30% emission reductions in unidirectional, and up to 112% and 165% in bidirectional charging. The second and third models achieve smaller cost and emission reductions when considering minimum charging currents and minimum state-of-charge user preferences requirements.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"146 ","pages":"Article 104829"},"PeriodicalIF":7.3,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In view of that, this study quantifies the financial and environmental benefits of an IRHB in an urban context and compares it with different separated railway-highway (SRH) scenarios using a Multi-Criteria Decision Analysis (MCDA). Based on the findings, in urban areas where land is at a premium, an IRHB is a more cost-effective infrastructure in terms of land acquisition, house demolition, and environmental impacts than separate elevated railway and highway bridges. Furthermore, it is a strategic approach to urban development, balancing short-term financial costs with long-term environmental benefits.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"146 ","pages":"Article 104847"},"PeriodicalIF":7.3,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate travel time is the most influential factor affecting range anxiety, expressing a logarithmic relationship characterized by diminishing marginal effects.

Using a tripartite evolutionary game model, we analyze the impact of research subsidies, charging station subsidies, road access privileges, and emission penalties on stakeholder strategies. Theoretical analysis and numerical simulations based on real-world data reveal that standalone policies fail to achieve the ideal equilibrium where all stakeholders fully transition to ELVs. Among policy measures, penalties for internal combustion logistics vehicles (ICLVs) are the most effective initial measures. These policies encourage logistics companies to adopt ELVs and motivate manufacturers to prioritize ELV research, but have limited influence on leasing companies. Charging station construction subsidies play a pivotal role in engaging leasing companies. We also identify the optimal policy mix to balance transition speed and cost-effectiveness. In addition, reallocating research subsidies to charging station construction accelerates the transition further.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"146 ","pages":"Article 104838"},"PeriodicalIF":7.3,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144220946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
