After evaluating 23 underpasses with line transects and infrared cameras, we found that all underpasses were used by wildlife, with nine protected mammals recorded, while Tibetan antelopes (<em>Pantholops hodgsonii</em>) used exclusively larger underpasses during migration. Smaller underpasses located further from highways were more effectively used. This first assessment of WCSs distribution and density along the railway, comparing large and small WCSs, recommends prioritizing larger WCSs construction tailored to Tibetan antelope migration needs in future designs.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"146 ","pages":"Article 104866"},"PeriodicalIF":7.3,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144364772","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}

However, data-driven approaches require substantial user-specific data, limiting their effectiveness during the early stages of vehicle ownership or for newly registered EVs with limited historical records. This study introduces the Energy Consumption Transformer (ECT), a large-scale pre-trained model designed for data-scarce scenarios. ECT leverages transferable prior knowledge learned from over 310 thousand real-world trips. This pre-trained knowledge is then integrated with proprietary knowledge from limited EV trips, enabling accurate prediction even with minimal data. The pre-training is conducted using multi-city, multi-model datasets, ensuring the generalization of the learned knowledge. Results show that ECT outperforms existing methods in few-shot scenarios and bridges the multi-month prediction service gap during data collection. Furthermore, ECT provides efficient inference, with a response time ranging from 0.14 to 0.28 ms/trip. This study facilitates immediately available prediction without requiring extensive user-specific data collection.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"146 ","pages":"Article 104830"},"PeriodicalIF":7.3,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331054","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}

Enhancing data preprocessing through time alignment and anomaly removal, this study analyzed 14,570 HDDVs, showing a 78.8 % NO<sub>X</sub> reduction in China VI versus China V vehicles.

Both NO<sub>X</sub> emissions and fuel consumption increased at low speeds. Lower ambient temperatures minimally affected NO<sub>X</sub> emissions and fuel consumption, but increased NO<sub>X</sub> outliers. Elevated altitude slightly increased fuel consumption, while its influence on NO<sub>X</sub> emissions showed no consistent trend.
