Transport policies targeted towards cutting greenhouse gas (GHG) emissions from private cars are subject to increasing scholarly attention. An increasing literature investigates the role of policy entrepreneurs in promoting climate policies. Their role in maintaining policies is, however, rarely addressed in this literature. As climate policies are contested, they are also prone to weakening and rollbacks – and policies targeting private cars are no exception. Comparing the electrification of the vehicle fleet and increased use of biofuels in the Norwegian private car transport segment, we argue that by concentrating on the processes and analysing the connection between actors and policies across measures, we can better understand why and how policy instruments are maintained. The cases are interesting because they are the two most important climate policies in Norway targeting private cars. To stay successful, we find that policy entrepreneurs have to continue to remain active and alert after a policy-decision in their favour has been taken. To avoid rollback and achieve further policy change, they make use of different entrepreneurial strategies. We also find that in a democracy like Norway, where minority governments are common, the national budget negotiations create particularly important policy windows for low-carbon transport policies. We conclude that policy entrepreneurs play pivotal roles in maintaining policies and preventing backlash. Successful policy entrepreneurship is conditioned by persistence and ability to analyze the parliamentary situation combined with skillful choices of entrepreneurial strategies.

How travellers perceive the quality of public transport services has profound influence on their satisfaction and thus of their inclination to choose this mode of transport. Punctuality, which may be interpreted as timetable adherence or overall travel time predictability, is often pointed out as the most important constituent of overall service reliability of public transport systems. However, in order for operators to be able to improve passengers’ perceptions of service reliability, an empirically derived linkage between perceptions and actual service performance indicators must be established. This paper has addressed this issue by using six-year longitudinal dataset on half-year resolution level from the regional public transport system of Scania, Sweden, to relate various indices of actual service reliability, obtained from service performance indicators, to stated satisfaction with punctuality for trains and buses. This was done by means of linear regression models using a stepwise approach to eliminate redundant variables, based on the level of independence of each variable. The results indicate that average arrival delay and frequency of early departures in relation to schedule are the most important factors of service reliability to explain travellerś perceptions of punctuality. Thus, for instance, average arrival delay and schedule adherence are indicated to have three times larger impact on satisfaction than frequency of early departures. But we also find that other service quality factors such as cleanliness, safety, and seat availability are also indicated to have an impact on perceptions of service reliability. It is emphasized that appropriate service performance data, and their relation to perceptions of passengers, constitutes crucial information for commercial and public providers in their ambition to improve levels of passenger satisfaction with operations but that the optimal level of punctuality is likely to differ between different passenger categories, and thus services.

Purpose
Research on dry ports has grown globally, yet systematic evidence on Africa remains fragmented across numerous journals, countries and a loosely connected author network. This fragmentation limits the development of an Africa-specific conceptualisation of dry ports and makes it difficult to compare experiences across regions. This article presents a systematic literature review and bibliometric analysis of dry port studies with an explicit African focus, consolidating dispersed evidence into a continent-centred synthesis.
Methods
Searches in Scopus, Web of Science, EBSCO Host, Engineering Village, ProQuest and Google Scholar identified 418 records. After applying predefined inclusion/exclusion criteria, 70 publications (69 journal articles and one book chapter) were retained for analysis.
Results
The evidence base spans 51 journals and 27 African countries, with concentrations in Nigeria, Ethiopia, Tanzania, South Africa and Kenya. Results show a marked post-2019 increase in African dry port studies but reveal a fragmented author network and dispersed publication outlets. Synthesis across the retained studies highlights three continent-specific features: (i) dry ports often respond to structural constraints including weak inland connectivity, customs/clearance frictions, and limited multimodal integration; (ii) governance and institutional arrangements—including concessioning, regulatory coherence and overlapping mandates—strongly determine performance; and (iii) corridor logistics and regional integration shape the siting and roles of inland terminals beyond seaport decongestion rationales.
Conclusions
The review contributes an Africa-centred consolidation of a previously fragmented field, clarifies where and why research attention clusters, and distils core themes that distinguish African dry ports from developed-economy trajectories, providing a baseline for comparative work and future inquiry. In so doing, the review advances theory on port–hinterland systems by foregrounding institutional and corridor-based dynamics. It offers policy-relevant insights for designing dry ports as instruments of regional integration rather than purely as seaport extensions.
关于干港的研究已经在全球范围内发展起来，然而关于非洲的系统证据仍然分散在许多期刊、国家和一个松散连接的作者网络中。这种碎片化限制了非洲陆地港概念的发展，并使比较各区域的经验变得困难。这篇文章提出了一个系统的文献综述和文献计量分析的干港研究与明确的非洲焦点，巩固分散的证据到一个以大陆为中心的综合。方法在Scopus、Web of Science、EBSCO Host、Engineering Village、ProQuest和b谷歌Scholar中检索到418条记录。在应用预定义的纳入/排除标准后，保留70篇出版物（69篇期刊文章和1本书章节）用于分析。结果该证据库涵盖51种期刊和27个非洲国家，主要集中在尼日利亚、埃塞俄比亚、坦桑尼亚、南非和肯尼亚。结果显示，2019年后非洲干港研究显著增加，但作者网络分散，出版渠道分散。对留存研究的综合分析强调了三个特定大陆的特征：(i)陆港经常受到结构性限制，包括内陆连通性弱、海关/清关摩擦和有限的多式联运一体化；（ii）治理和制度安排——包括特许权、监管一致性和重叠任务——在很大程度上决定了绩效；(3)走廊物流和区域一体化塑造了内陆码头的选址和作用，超出了海港缓解拥堵的理由。该综述有助于以非洲为中心，整合以前分散的领域，澄清研究重点集中在哪里以及为什么集中，并提炼出将非洲干港与发达经济轨迹区分开来的核心主题，为比较工作和未来的调查提供基线。在此基础上，本文提出了基于制度和走廊的动态机制，从而推进了港口-腹地系统的理论研究。它为将陆港设计为区域一体化的工具而不仅仅是海港扩建提供了与政策相关的见解。

This study explored public opinions on the expansion and safety of autonomous shuttles using data from the Connected Autonomous Shuttle Supporting Innovation (CASSI) pilot program in Cary and Charlotte, North Carolina. The objective is to understand the factors influencing public support or opposition to autonomous shuttle expansion, investigate perceptions of safety, and uncover reasons for reluctance to re-ride. For this purpose, the study employed ranked cross-correlation analysis, association rule mining, mediation analysis, and thematic analysis. Key mediators, such as post-ride safety perception and the intention to re-ride, were identified, and the findings reveal that they significantly influence public support for shuttle expansion. In addition, the importance of positive initial experience, timely service, and enhanced operational performance in fostering public acceptance was also highlighted. Overall, the findings underscore the need to address safety concerns, ensure accessibility, and improve shuttle operations to promote large-scale adoption. This study provides valuable insights into the intersection of public opinion on safety and autonomous shuttle operation, guiding policymakers and service providers to better integrate these vehicles into urban transportation systems.

Rapid motorization in Pakistan has intensified air quality challenges, yet limited research has examined how vehicular growth contributes to environmental degradation and what institutional responses have emerged. This study investigates the linkages between rising vehicle numbers, weak regulatory enforcement and deteriorating air quality in Islamabad, Pakistan. Qualitative in-depth interviews were conducted with officials from the Capital Development Authority, Environmental Protection Agency and Islamabad Transport Authority to explores institutional capacities, policy implementation gaps and emerging strategies such as public transport expansion and electric vehicle promotion. Twelve participants were selected through purposive sampling, and the collected data were analysed thematically using MAXQDA software. The findings reveal that rapid growth in private vehicle ownership, combined with poorly maintained fleets and the absence of systematic inspection regimes, has accelerated atmospheric emissions in the capital. Institutional inertia, resource scarcity and socio-economic justifications for tolerating old vehicles further exacerbate the problem. While initiatives such as the Bus Rapid Transit system and planned electric vehicle policies signal potential, their scale remains insufficient. The current study contributes to debates on urban air quality governance in the Global South by highlighting how weak institutional frameworks and competing development priorities undermine environmental sustainability. It calls for integrated policy reforms, investment in sustainable public transport and robust enforcement mechanisms to mitigate transport-related emissions.

Mobility-as-a-Service (MaaS) is emerging as a paradigm-shifting solution for urban transportation, yet its research and implementation have been largely confined to developed countries. A significant knowledge gap exists regarding its viability in the unique context of developing nations, which are often characterized by fragmented transport systems, cash-dominant economies, and severe traffic congestion. This study addresses this gap by investigating the factors influencing MaaS adoption willingness among university students in Hanoi, Vietnam, a city that epitomizes these challenges. We frame our analysis through a “cash, code, and congestion” lens to dissect the structural and behavioral barriers to adoption. Employing a survey-based methodology with 372 student respondents, this research utilizes Classification and Regression Trees (CART) to develop predictive models for two distinct user segments: private vehicle users and public/shared transport users. The models identify the key determinants of adoption and reveal the detailed decision-making profiles of each group. Our findings reveal a strong latent demand for MaaS, but uncover fundamentally divergent adoption logics between the two segments. For private vehicle users, adoption is primarily driven by their existing digital habits with ride-hailing apps, with financial considerations acting as a secondary factor. Conversely, for public/shared transport users, the practical utility of their daily journey, particularly commute distance, is the most critical predictor. The results underscore that a one-size-fits-all MaaS strategy is unviable. As a conclusion, this study provides empirical evidence for segment-specific pathways to MaaS adoption in a developing country context. We propose that successful MaaS implementation in a Vietnamese context such as Hanoi requires targeted value propositions: focusing on cost-efficiency and superior convenience to attract private users, while emphasizing operational reliability and functional optimization for public transport users. These strategies must be coupled with systemic solutions to overcome the “cash, code, and congestion” barriers, ultimately positioning MaaS as a key enabler of sustainable urban mobility.

The aim of the article is to measure changes in the level and shape of the diurnal profiles of car traffic and bus demand in Rzeszów (Poland) over 2018–2024, and to assess the persistence of these changes. The study analyzes the interplay between transport supply (e.g., the organization and functioning of public transport) and demand (i.e., behavioral changes among residents), offering a comprehensive view of how the pandemic and the geopolitical crisis associated with the war in Ukraine disrupted mobility patterns and prompted adaptive responses within the urban mobility system. Rzeszów, as a dynamically developing urban center, provides a valuable case for examining the long-term implications of pandemic-induced restrictions. By observing the forced reduction in mobility during the pandemic, the study identifies where and to what extent spatial mobility can be limited without compromising the resilience of the socio-economic system. This empirical context offers a unique opportunity to explore how urban mobility can be managed more effectively and where unnecessary or excessive movement might be reduced in pursuit of broader sustainability goals. The findings contribute to current European and global debates on sustainable urban mobility, demonstrating that targeted mobility management − guided by evidence from real-world constraints − can support the transition toward more resilient, efficient, and environmentally responsible transport systems. In light of broader challenges such as war in Ukraine, inflation, migration, and the digitalization of transport services, the Rzeszów case exemplifies how cities can respond to disruptions while aligning with long-term policy objectives related to climate neutrality, accessibility, and smart urban growth. Policy implications are articulated across four scales. Citywide, the observed re-profiling of demand, subdued mornings and stronger afternoon/early-evening activity, supports selective mobility reduction and time-sensitive allocation of public-transport supply and traffic management. Corridor-level, central corridors and radial approaches to the city centre emerge as candidates for strengthening collective transport, while peripheral distributor corridors with rising car pressure merit targeted service upgrades paired with calibrated demand restraint. At the junction-level, inner-city junctions and transfer nodes are suitable for signal priority, access management, and turn-movement control; time-of-day management should prioritise 14:00–18:00 and after 18:00.

At the junction-level, inner-city junctions and transfer nodes are suitable for signal priority, access management, and turn-movement control; time-of-day management should prioritise 14:00–18:00 and after 18:00.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"23 ","pages":"Article 101644"},"PeriodicalIF":3.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145570000","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}

A select group of world cities has passenger boat services as an integral part of their public transport system. Early Bangkok had an almost exclusively water-based transport system, largely replaced by roads with rail added in the 20th century. Boat services were restored on a limited number of waterways and have grown rapidly in popularity and patronage, including for commuting to work and school. In this study, the service coverage of the urban territory of one such boat service is examined, along with its time efficiency. The Saen Saep service parallels Phetchaburi Road, which is at saturation. The boat service provides a faster service than is available by car, bus or motorcycle on this transport corridor. There remains considerable growth potential of the boat service since it is the exclusive user of the khlong. This study supports the view that water-based public transport could be greatly expanded to become a central feature of Bangkok’s mobility system.
