To support the energy demand of EVs at fast-charging stations whilst minimizing the cost of the system, a mixed-integer optimization model is developed considering the spatiotemporal demand (existing demand and EV demand), the details of the electric grid distribution network, spatiotemporal power generation of solar panels, energy storage systems’ (ESSs’) charge/discharge schedule, and the capacity constraints. The case study (major cities in Michigan) shows sensitivity to the seasonal variation in the grid and solar conditions and the DER’s unit cost. Based on the result, providing the maximum area for solar panels leads to the maximum cost savings. Lithium-ion SLBs offer a cost-effective solution for energy storage, efficiently utilizing time-of-use electricity rates and intermittent solar energy.

For this reason, we conducted a choice experiment(CE) in Heilongjiang province, which is located in northeastern China, with the aim of investigating consumers’ choice preferences for EV in severe cold regions. In this paper, we applied multinomial logit models(MNL), random parameters logit models(RPL), and latent classes models(LCM) to explore the differences in attribute preferences and willingness to pay(WTP) for consumers’ choice of EV in cold environments. The results of this study show that the respondents are more concerned about the purchase price, driving range, charging station density, and charging time of EV. Based on the results of the LCM model, respondents were divided into two categories: price-sensitive type and charging time-sensitive type. We found that low-income women who own a garage are more likely to fall into the first category, focusing more on the purchase price, fuel cost, and carbon emission attributes of the EV. Higher-income men without a garage are more likely to fall into the second category, focusing more on purchase price, charging time,driving range, and the car’s power performance attributes during the selection process.

China, the United States, and the United Kingdom led environmental EV research during this period, with cluster analysis revealing associations between international collaboration patterns, geographical attributes, and research performance. Countries with strong qualitative research performance showed corresponding excellence in sustainability indices. Comparative analysis revealed that, among major journals and countries, articles in multidisciplinary journals (AMDJ) demonstrated stronger research performance, while articles in environment-specific journals (AESJ) were characterized by stronger research leadership. Analysis of EV research revealed several core themes, including climate change responses, energy management systems, battery and environmental sustainability, and renewable energy, alongside expanding research on charging infrastructure that parallels EV diffusion Furthermore, AESJ emphasized environmental, economic, and system-level perspectives of EVs, while AMDJ primarily addressed EV value chain development, infrastructure optimization, and challenges associated with technological implementation. This study represents the first thorough analysis of environmental EV research across sub-domains, one which identifies associations between research performance, collaboration, and sustainability measures.

The research team collaborated with Massachusetts Bay Transportation Authority (MBTA) to utilize Outdoor Information Panels (OIPs) along major highways to deliver real-time travel information (RTTI) to encourage increased transit use. An online interview and a household survey were conducted in sequence to gather Great Boston Area (GBA) travelers’ travel experience, preferred RTTI contents, OIP graphic designs, and their stated mode shift in response to OIPs. The top three information items found to encourage transit use are real-time total travel time, next two train arrivals, and real-time parking availability. Additionally, travel cost is more influential for commuter rail (vs. subway) trips and major event (vs. generic) trips. 79% of transit user participants agree that OIPs would improve their travel experience. Trips with more flexible schedules and/or less requirement on carrying passengers and goods, such as social/recreational and major-event trips, are more influenced by RTTI than work, family, and shopping trips. Transit nonusers show a lower tendency to increase their transit use compared to transit users, with their potential increases varying more by trip purpose. A 2.1% emission reduction from work trips is estimated using a regional travel demand model for the GBA. Frequent transit users and nonusers (car users) contribute significantly to emission reductions. Frequent transit users contribute due to their substantial increase in transit use per person, despite being a smaller proportion of the traveling population, while nonusers contribute due to their large proportion, despite a smaller per-person increase in transit use.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"19 3","pages":"Pages 247-261"},"PeriodicalIF":3.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings indicate that students are responsive to the financial aspects of cycling, suggesting that subsidies for the purchase of bicycles or bike-share services could increase cycling rates. However, the study also highlights that infrastructure factors—such as the availability of dedicated cycle lanes, secure bicycle parking, and e-bike charging points on campus—are equally, if not more, important in determining the likelihood of students cycling to university. Additionally, linear green infrastructure, such as roads with greenery along the edges (e.g. grass verges, trees, or bushes), was found to be the second most important type of infrastructure for encouraging students residing in the urban area to cycle. Latent psychological factors, such as perceptions of urban safety for cycling and anticipated health and fatigue effects, were also significant in influencing the decision to cycle.
