The results show that a 1℃ increase in average temperature facilitates asphalt pavement aging rate by 3% to 4%, significantly increasing pavement damage, maintenance frequency and costs. For instance, maintenance costs in New Delhi are projected to increase by up to 22.2% under SSP585 compared to historical period. Global road maintenance costs are projected to rise by $16.5–$33.0 billion, with U.S. costs increasing by $0.5–$1.0 billion. High-performance mixes, such as polymer-modified asphalt, can effectively mitigate the impact of future climate change by improving asphalt elasticity and slowing its aging process, thereby reducing the maintenance frequency and costs. Although their higher initial material cost may present economic trade-offs, the extended service life and reduced maintenance costs can offset these costs. Policymakers can utilize these findings to optimize maintenance investments, while engineers may adopt adaptive designs or materials to reduce climate-related impacts on road infrastructure.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"142 ","pages":"Article 104702"},"PeriodicalIF":7.3,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593625","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 show that HSR connectivity, as well as the number of stations and routes, increased carbon emission efficiency by 0.4%, 0.2%, and 0.3%, respectively. The effect is more pronounced in smaller cities and regions with lower marketization. Micro-level data reveals that the effective impact radius of HSR is 2000 m. HSR increases fossil energy consumption in firms while reducing electricity consumption. The primary mechanism by which HSR reduces overall carbon emissions is by improving the fossil energy carbon emission efficiency of firms. Parallel trend tests, placebo tests, and endogeneity analyses all support these findings. The results provide valuable insights for the location of industrial parks near HSR stations and highlight that power rationing may limit the speed of carbon reduction.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"142 ","pages":"Article 104685"},"PeriodicalIF":7.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143552150","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}
