A comprehensive understanding of stakeholders’ views on current challenges, opportunities and the overall direction of transport policy and practice was examined, including the role of technology and community involvement. Seven themes were identified: policy and governance; community and stakeholder participation; infrastructure and resource allocation; innovation and adaptive strategies; data-driven and evidence-based approaches; operational efficiency and effectiveness; and environmental sustainability and health. This paper further investigates these themes and their interconnections using a systems thinking approach, revealing a complex web of feedback loops and leverage points that shape the urban mobility landscape. Our findings highlight the critical role of integrated policy frameworks, community engagement, technological innovations, and a multidisciplinary approach in transitioning towards a more sustainable, efficient, and inclusive urban mobility system. By mapping the intricate interactions between these themes, this study contributes to a deeper understanding of the systemic changes required to enhance sustainable urban mobility in Dublin and offers insights that could inform policy and practice in other urban contexts facing similar challenges.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101280"},"PeriodicalIF":3.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142699566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a comprehensive design of an intelligent decision support system (DSS) to address these gaps. The design includes conducting a system impact analysis to identify new stakeholders, proposing a new DSS architecture with review and learning functions, and concretizing various potentially effective decision-making models and information inputs. Using a real-world freight delivery scenario and a risk-based decision-making approach, we present a case study to instantiate the DSS design, including graphical user interface designs and a step-by-step use case scenario. This work aims to adapt post-diagnosis decision-making for automated trucks at both technological and managerial levels, thereby enhancing vehicle reliability and transport efficiency.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101284"},"PeriodicalIF":3.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142757205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study uses a combination of exploratory data analysis and random forest regression to investigate restoration time − a key delimiter of corrective maintenance. Using data from the Swedish railway network, the study investigates the driving factors of restoration times. The maintenance contractor and the type of incident including repair action, failure cause, and the number of concurrent incidents were found to have the highest influence on restoration times respectively. Weather parameters only show discernible influence (both direct and indirect influence) beyond marked thresholds. For the Swedish railway network, these thresholds are −20 °C and 23 °C maximum daily temperatures, 18 mm maximum daily precipitation, and 20 m/s maximum windspeed. Precipitation’s and windspeed’s direct effects become more prominent beyond 50 mm and 35 m/s respectively.

EV adoption by residents of multi-unit residential buildings (MURBs) lags far behind, dampening adoption of EVs and potentially creating an equity gap across income and race categories. Semi-structured interviews were conducted with a sample of 30 MURB property managers in the Phoenix metro area to understand how they think about investments in EV charging infrastructure. The interviews were analyzed to identify concerns, constraints, and opportunities to promote faster electric vehicle supply equipment (EVSE) deployment in MURBs, and to understand how deployment dynamics influence equity implications for renters. To do this, the proposed research questions were: 1) What are the perceptions of MURBs managers about charging infrastructure demand and installation? 2) What experiences have MURB managers had regarding installing and/or managing charging infrastructure? and 3) What does the current layout for MURBs complexes look like, and what limitations are there in the existing infrastructure? We found that apartment complexes present financial constraints for charging infrastructure installation when retrofitting charging infrastructure. New business models that can make EV charging profitable are needed, and there are limitations in electrical infrastructure requirements. Access to charging infrastructure presents equity issues among different renter income groups because properties catering to higher-income residents are more inclined to install EVSE compared to rental properties serving lower-income residents.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101263"},"PeriodicalIF":3.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings of our study demonstrate that the perceived advantages, perceived barriers, public opinion, and government initiatives significantly influence the desire of women in Saudi Arabia to use HFCVs.

To assess the impact of waiting time, the model compares an acceptable waiting time (5 min) with the average waiting time of the service. A threshold walking time of 8 min defines the service coverage area. Results indicate that the collective fixed-route service covers only 39.49% of the city’s urban area.

Yet, there is little research on how these changes in urban form could affect an important relationship in transportation and health: vehicle miles traveled (VMT) and air pollution. For example, studies show urban areas typically have a higher building density, which can trap in more air pollution relative to rural or open spaces where pollution can disperse more widely. A lack of detailed data on VMT, as well as methodological challenges have made assessing this relationship difficult. To address this, we use a quasi-experimental framework and a unique dataset to examine how a dramatic change in vehicle miles traveled (VMT) during the COVID-19 pandemic affected air pollution and if or how urban form moderated this relationship. We use detailed county-level daily VMT and air quality data in the contiguous U.S. between January and August 2020. Our results show statistically significant positive correlations between VMT and air pollution in urban counties, but in rural counties the marginal effect of VMT on air pollution was either statistically insignificant or very small. Results from this study suggest that efforts to reduce the marginal impact of VMT or vehicle emissions in urban areas could lead to a greater improvement in air quality when compared to more rural counties due to the built environment.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"28 ","pages":"Article 101288"},"PeriodicalIF":3.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
