This study investigates the completeness, positional accuracy, and reliability of traditional utility records compared to Subsurface Utility Engineering (SUE) investigation data by examining documented utilities for a highway reconstruction project in South Dakota. SUE investigations followed the Quality Level standards defined in the American Society of Civil Engineers (ASCE) 38–22 “Standard Guideline for investigating and documenting existing utilities.” A composite map was developed by overlaying the traditional and SUE investigation datasets. An analysis of the linear footage mapped revealed significant under-documentation in the traditional records, known as One Call records, with SUE investigations designating and mapping 160% more utility infrastructure across all asset types. Positional accuracy metrics further exposed deficiencies in traditional mapping. Only 32% of utility footage analyzed aligned within 2 feet (ft) when comparing One Call records to SUE investigation data. Moreover, about 21% of utilities in One Call records deviated by over 20 ft compared to the SUE data. These findings demonstrate the necessity of rigorous SUE practices to mitigate risks from inaccurate and incomplete utility data. SUE provides comprehensive, precise subsurface infrastructure mapping, which is essential for informed engineering design, conflict prevention, and efficient, low-risk construction. This study affirms SUE’s value in reducing utility-related risks and supporting efficient project delivery through accurate subsurface mapping.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"32 ","pages":"Article 101539"},"PeriodicalIF":3.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144694814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments were conducted on isomorphic courses to compare driving behavior across a real vehicle, a DS, and a dot vehicle (a sprite in a driving game).

MCI considers contextual integrity (CI) in tandem with societal preferences and individual level preferences, which is captured using demographic data. Therefore, it captures the individual-level, group-level, and societal-level factors that drive peoples’ preferences regarding AV privacy. Empirical insights into the relationships among the social forces captured at these three levels are drawn from survey data collected in South Korea. The findings reveal that although social goals and demographic variables initially show some association, the introduction of CI parameters significantly diminishes this relationship, highlighting the primacy of informational contexts in shaping AV privacy attitudes.

By advancing the CI framework to include social goals, this study contributes to the broader discourse on responsible innovation, offering a robust approach to managing privacy challenges in emerging technologies.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"32 ","pages":"Article 101536"},"PeriodicalIF":3.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144662017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, Zero Emission Vehicles (ZEVs) are essential for decarbonizing the transport sector and reducing air pollution. To estimate the potential benefits and burdens of these novel powertrains, the Life Cycle Assessment (LCA) methodology can be used and offer a comprehensive approach. However, when comparing ZEVs to diesel Internal Combustion Engine Vehicles (ICEVs), it is crucial to rely on robust results to ensure comparability. The present study presents a systematic literature review of LCA applications to Heavy-Duty Vehicles (HDVs), employing a rigorous methodology to provide an unbiased and comprehensive overview. The study aims to: (1) investigate the state-of-the-art methodological approaches in LCA implementation to HDVs (i.e., qualitative assessment) and (2) quantify the carbon footprints of current ICE-HDVs and ZEVs (i.e., quantitative assessment). After a screening step, a sample of 24 publications, comprising both scientific articles and industrial reports, has been extracted from several databases. Quantitatively, the analysis highlights a significant variability of the carbon footprint results, ranging between 431–1780 tons CO<sub>2</sub>eq for diesel ICEVs, 175–1626 tons CO<sub>2</sub>eq for battery electric vehicles, 366–2944 tons CO<sub>2</sub>eq for fuel cell electric vehicles. Instead, from the qualitative standpoint, the review reveals that, while quite consensus exists on the functional unit, there are still major differing methodological choices that cause significant variability of carbon footprint among studies. Also, the analysis highlights the strong need for improved primary data coverage and greater harmonization of LCA methods and assumptions.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"32 ","pages":"Article 101563"},"PeriodicalIF":3.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144780870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed greater trust and less blame attributed to humans in both ATC and VD, except in the Level 3 AI trainee model where humans were blamed more than AI. We also found both similarities and differences in people’s perceptions of the two contexts.

Nevertheless, there is a lack of understanding about citizens’ perceived roles, responsibilities, and preferred involvement in sustainability transitions, not least in contexts beyond inner city environments. Based on five focus groups conducted in a semi-urban area outside Stockholm, Sweden, this study explores how citizens envision and relate to sustainable mobility in their local context, what measures they propose and how they perceive their role in a sustainable transition. Based on the findings, the study suggests that the design of future sustainable transport policies must be informed by the complex and often conflictual relationship between greater sustainability, and people’s current everyday lives as configured around meaningful practices. As illuminated in the studied semi-urban context, many established everyday practices are car-dependent.
