Battery-electric vehicles (BEVs) are envisioned as the best option, thanks to zero exhaust emissions and regenerative braking. BEVs can be human-driven or autonomous and will co-exist with internal combustion engine vehicles (ICEVs) for years. BEVs can help at complex intersections where traffic is saturated. However, their benefits can be reduced by poor intersection management (IM) strategies that coordinate mixed traffic configurations inefficiently. This paper studies energy savings and emissions reduction using BEVs mixed with human-driven ICEVs under eight relevant IM approaches. It shows that adding BEVs has impacts on throughput, energy consumption, waiting delays, and tail-pipe emissions that depend on the specific IM approach used. Thus, this study provides the information needed to support an optimal choice of IM approaches considering the emerging trend towards electrical mobility.</p></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1361920924003602/pdfft?md5=b6a8bb284ba3b20d8741d5ab796e7153&pid=1-s2.0-S1361920924003602-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142169138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This extends the theory of institutional entrepreneurship by demonstrating how regulatory frameworks can incentivize corporate actors to adopt sustainable practices. It highlights the critical role of regulatory environments in shaping institutional entrepreneurship, suggesting that stringent regulations can effectively drive organizations toward sustainability. This perceived normative and cognitive pressure aligns with Levy and Kolk (2002), which suggests that climate strategies are formulated by managers from countries where such environmental practices are strictly required (<span><span>Pinkse, 2007</span></span>). Compared with previous studies, this paper reveals that collective institutional entrepreneurship can create opportunities for integrating sustainability policies under favorable conditions. Unlike <span><span>Jolly et al. (2016)</span></span>, who highlighted the isolated and contested actions of individual actors, this study shows that sustainability policies and developments by legacy aviation groups often overlap at both micro (individual) and meso (organizational or institutional) levels. This intersection of corporate values with individual passengers, other subsidiary airlines and international community expectations underscores a collective institutional entrepreneurship that fosters integrated sustainability policies under favorable conditions.</p></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1361920924003511/pdfft?md5=7b1bbe314e8b2f8248cc0f76db5af40b&pid=1-s2.0-S1361920924003511-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142157524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we present the first assessment of roadkill patterns of amphibians in the Hainan tropical rainforest of southern China, based on extensive field surveys covering 58 road transects in 2021 and 2022. We investigated the effects of species characteristics, seasons, and environmental factors on amphibian roadkill patterns. We recorded 503 amphibian carcasses and identified 13 amphibian species. Abundant species are more likely to be killed. There were no significant differences in the roadkill observations between the dry and wet seasons. The number of roadkill observations correlated positively with the percentage of area with buildings. Our findings provide new insights into the ecological effects of roads and transportation in Asian tropical rainforests, which will help design and implement conservation actions. We suggest prioritizing permanent mitigation measures to reduce roadkill risk for abundant species on roads with a relatively high percentage of area with buildings in the Hainan tropical rainforest.</p></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":null,"pages":null},"PeriodicalIF":7.3,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142157525","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}

This study unveils the impact of fellow passengers on travel experiences and categorises interactions as positive, neutral, or negative, elucidating key features of this dynamic. Understanding these interactions is pivotal for developing interventions aimed at improving transportation accessibility.
