Despite its significant technical potential, the social dimensions of V2G adoption remain underexplored, particularly in understanding EV users' concerns and perceptions about this emerging technology. By conducting interviews with 33 battery EV users in Utrecht, Netherlands, this research investigates individual concerns and opinions regarding V2G applications, focusing on potential battery degradation and its implications for daily EV use. The findings reveal a spectrum of concerns among users. Private EV owners who prioritize battery longevity frequently express apprehension about the potential for accelerated degradation associated with V2G usage. In contrast, users who have greater confidence in the technology are generally less concerned. Many participants highlighted the need for robust, evidence-based information on the impact of V2G on battery health before deciding to engage in such programs. EV daily usage and mobility patterns also play a role in this process, where those with high daily mileage or irregular driving patterns, are concerned about the potential impact on vehicle availability and performance. These insights underline the need to address user-specific concerns and tailor V2G programs to accommodate diverse EV usage patterns.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"164 ","pages":"Pages 231-240"},"PeriodicalIF":6.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Walking accessibility disparity or inequity among different age groups is further quantified using Gini coefficients and Theil indices. The comparative case study focuses on Kwun Tong, an old urban area, and Kai Tak, a new development area in Hong Kong. The results show that the new development area exhibits lower walking accessibility across all age groups and a higher level of inequity for young and middle-aged pedestrians compared to the old development area, while the inequity difference for the elderly is not significant. This disparity can be attributed to the concentration of POIs within a few business clusters and insufficient pedestrian facilities. Additionally, the elderly have the worst walking accessibility among the three age groups. The findings highlight the necessity to incorporate pedestrians’ diverse preferences in planning new development areas to create a pedestrian-friendly environment for all.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"165 ","pages":"Pages 97-106"},"PeriodicalIF":6.3,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, amidst the array of novel concepts, the industry's understanding of the enablers and barriers of ULS remains incomplete. This paper introduced an analytic framework for both public and private sectors to revisit the ULS plans in a nascent stage. Through a comprehensive document review, we delineate the typical approaches to initiate ULS from the perspectives of government and consortia. Fifty-four factors characterizing the sponsors' visions, project startup prerequisites, and implementation barriers were identified. We conducted semi-structured interviews and a two-round Delphi survey with 18 experts to elucidate how these factors influence ULS adoption and explore causal relationships in new system front-end planning. Subsequently, a grounded-theory framework was constructed to interrelate multi-thematic concepts. Our research findings indicate several key points: (i) the gestation of ULS project is a collaborative effort between public and private sectors looking for shared visions and common interests; (ii) the unilateral promotion of emerging transport systems/modes could face diverse barriers and disadvantages due to the complexity, uncertainties, and lack of precedents; (iii) positioning ULS programs within a public-private partnership agreement fostered by incentive policies is crucial to achieving social, technological, and business preparedness for transformation.

{"title":"From pilot to policy: Examining the transition towards institutionalized practices in freight curbside management","authors":"Laura Palacios-Argüello ,&nbsp;Juan Pablo Castrellon ,&nbsp;Ivan Sanchez-Diaz","doi":"10.1016/j.tranpol.2025.02.005","DOIUrl":"10.1016/j.tranpol.2025.02.005","url":null,"abstract":"<div><div>Streets are contested urban public spaces due to their limited availability. While they serve various functions, the needs of certain uses—such as freight—often have been overlooked in space allocation policies affecting urban livability. Recently, freight curbside management has emerged to address these conflicts, allowing service and delivery vehicles to better use street space, contributing to cities’ sustainability targets. Although pilots testing freight curbside interventions are a first step for policymakers to evaluate the effectiveness of these interventions, the transition from pilot to established practices remains underexplored. Therefore, the aim of this research is to understand the success and failure factors that influence the institutionalization process of interventions tested in freight curbside pilots. To achieve this, this paper analyses cases from various cities worldwide that have implemented such pilots, using the lens of institutional theory. Case selection criteria were based on the maturity level of freight curbside pilots. Specifically, the paper focused on those cases that had already implemented pilots, undergone monitoring, evaluation, and possible continuation processes. Data collection and analysis revealed coercive, normative, and mimetic forces driving change towards institutionalized practices. The data analysis identified 23 themes across four content domains, i.e., organizational, economic, technological, and regulatory. Successful institutionalization process relies on strategically selecting high demand loading zones and demonstrating public benefits. Enhancing user experience is also crucial. However, some interventions fail to become institutionalized due to regulatory constraints, business model issues, and land use regulations. This highlights the need for flexible, context-specific approaches. The analysis of institutional pressures revealed that coercive pressures influence transitions from themes related to the legal mandate of public agencies, pilot scope definition, and user experience, while normative pressures shape transition regarding public benefit, business models, stakeholder involvement, and data management themes. Mimetic forces guided early-stage pilots through lessons learned from cities with prior experience in curbside pilots. The findings provide recommendations and guidelines for the development of future pilots, useful for planners aiming at generating long-term curbside policies that solve freight-related street space conflicts.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"164 ","pages":"Pages 244-254"},"PeriodicalIF":6.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143378079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
