As the scarce scientific literature points to further hydrogen research, limitations in analyzed dimensions and the missing involvement of investing transportation companies, this paper compares the two technologies using an extended socio-technical approach. Successful transitions in long-established systems require a multi-dimensional view, and therefore, the theory of diffusion of innovation is extended with the PESTLE analysis, as political, economic, social, technological, legal, and environmental dimensions allow a systematic research. In order to provide a comprehensive comparison and a future technology indication, this study combines a literature review with 40 high-level expert interviews, paying particular attention to the contribution of new, unexpected narratives. Identified opportunities, and barriers reinforce advantages of BE-HDT, but opportunities of FC-HDT in individual dimensions and indicators show the high potential for system integration, with social and environmental factors contributing significantly to existing scientific research. However, as hydrogen is a key component of decarbonization, government should focus on a quota system for funded powertrain technologies to achieve a required tipping point as critical mass for widespread deployment, combined with targeted acceptance and information campaigns.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"195 ","pages":"Article 104455"},"PeriodicalIF":6.3,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683370","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}

A discrete choice random utility model is utilized to analyze weekly travel patterns and estimate changes in welfare in terms of consumer surplus by gender and travel purpose, based on a panel database that has information on multiple travel choices over 6 months. The results indicate a significant increase in the utility of the BRT and regular bus services for voucher recipients, leading to increased BRT usage, decreased regular bus usage, and travel time savings. The study also finds that travel vouchers notably enhance user welfare, especially for female participants and non-work-related trips, suggesting these trip purposes generate greater user benefits.

Sudden change to such intercontinental commuting due to lockdown restrictions during the COVID-19 pandemic provided a nuanced exploration of commuter attitudes and behaviour. Semi-structed interviews were conducted before (N = 40) and after the pandemic (N = 15). Interviews explored participants’ commuting perceptions, experience, attitudes and motivations. Findings show that effort justification (commuting as trade-off for living in Istanbul and/or in the preferred neighbourhood and as effective time use) is the primary psychological mechanism commuters use for rationalising the intercontinental commute. Our results confirm empirical research on residential location, family relations and career opportunities. This exploration contributes to urban scholarship by highlighting the relevance of intrinsic needs (i.e., place attachment) associated with urban characteristics of the city and the neighbourhood, and demonstrating the intersection of urban characteristics and psychological mechanisms in explaining commuting cognition and behaviour.

Results were presented to and stress-tested with 25 councillors, to understand to what extent sustainable transport policies for last-mile deliveries meet political will. Findings show that behaviour change, and collaborative schemes have the potential to have a stronger impact than new and clean technologies in reducing carbon emissions from last-mile deliveries, even though their implementation would be more difficult and less politically appealing. The paper also considers how different levels of governance can contribute to enable the decarbonisation pathway and reveals that lack of power, capacity and capabilities on local freight would be a major challenge for local governments.

However, many studies found that cycling during COVID-19 was primarily for recreation and exercise. In contrast, cycling for commuting declined, largely because commuting overall (especially into cities) was partially replaced by working from home. In 2020 and 2021, the City of Melbourne fast-tracked a range of cycling infrastructure upgrades in an effort to attract more workers back into the city using this sustainable transport mode. The upgrades were relatively modest – ranging from extending curb-protected lanes through a single intersection, to replacing a few kilometres of painted lane with a protected bike lane. This study examines how patterns of bicycle riding have changed in response to the COVID-19 pandemic, using bicycle count data from 15 automatic counters within 5 km of Melbourne’s city center. In addition, this paper isolates the impact of COVID-era infrastructure upgrades against the backdrop of huge fluctuations in bike riding from 2019 to 2022. Multi-level generalized linear modelling found that weekday bicycle counts were significantly dampened during lockdown and remain below pre-COVID levels on weekdays and at sites on off-road bicycle paths. However, when controlling for lockdown stage and seasonality, the average daily count at sites near upgraded infrastructure were 7.4 % higher (855 per day) than counts from sites that were never, or not yet, near upgrades (796 per day). This increase is notable given that almost all counter locations saw declines in bicycle counts even through 2022. These findings are particularly relevant for cities that are grappling with whether to continue with temporary or long-term cycling infrastructure upgrades. This study suggests that even relatively modest upgrades to cycling networks can have a measurable impact on cycling rates.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"195 ","pages":"Article 104438"},"PeriodicalIF":6.3,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619528","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}

Through ethnographic observations and interviews with cyclists, non-cyclists, and bike rental operators, it explores cycling practices within Hong Kong’s app-based bike-sharing landscape. Findings reveal that PA extends beyond individual experiences, shaped by the interplay between material infrastructure, cycling practices, formal regulations, and informal rules. Factors such as spatial (cycling areas), temporal (weather, nighttime), and material (bike parking, rental availability) conditions mediate PA. Symbolic and material power are evident in government policies that promote ‘safe cycling’ while restricting infrastructure development in urban areas, shaping cycling practices and reinforcing its marginalisation in urban mobility. Despite these constraints, residents actively reshape accessibility by informally redefining cycling spaces and reinterpreting bike reliability, both through physical and digital experiences, thereby materially and symbolically integrating cycling into transit-oriented mobility. The study also highlights the temporality of PA; for instance, night-time cycling remains viable for those leveraging cultural awareness of reduced law enforcement at particular times, preparing with proper lighting equipment, or benefiting from well-lit infrastructure. These findings demonstrate that PA is contextually produced, shaped by relational social structures rather than fixed attributes of individuals or infrastructure alone. The paper calls for policy approaches that recognise the intersubjective nature of PA, advocating for adaptive regulations and inclusive infrastructure to foster equitable and sustainable urban mobility.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"195 ","pages":"Article 104449"},"PeriodicalIF":6.3,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619368","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}

Furthermore, the results show that the overall inequality (measured by Gini indices) deviates from the standard range of Google-based values when the OSM’s point-based POI data is used.

The UAP narrowed disparities in road length (quantity) between interprovincial adjacent cities, promoted the coordinated development of road quantity and technical standards (quality) among intraprovincial adjacent cities, and enhanced cross-border road infrastructure connectivity, enabling less-developed cities to catch up with their more developed counterparts.
