Various jurisdictions have either initiated testing or provided their land for private companies to test AVs. Unlike human-driven vehicles, residents are unaware of which level of government will be involved in regulating AVs. While existing literature has focused on the regulatory framework, liability laws, and institutional reforms needed for AV integration, there is a limited understanding of how the public perceives government regulation of AVs and how these perceptions influence their willingness to ride in such vehicles. This study employed the Bayesian Networks approach to analyze data collected by the Pew Research Center in 2022, exploring residents’ perceptions of government regulation of AVs and its impact on ridership. Results indicate that political ideology and education level are key factors influencing residents’ perceptions of government regulation of AVs. People with higher education levels are less likely to perceive that the government will overregulate AV use. Similarly, compared to moderate or liberal Republicans, conservative Republicans are more likely to perceive that the government will overregulate AV use. In contrast, liberal Democrats and conservative Democrats are less likely to share this perception. Other factors associated with the perception that the government will go too far in regulating AV use include older and male residents. On the other hand, people who live in metropolitan areas, those who heard/read about AVs, high-income earners, Hispanics, African Americans, and mixed races are less likely to perceive that the government will go too far regulating AV use. Overall, the difference in the government’s perception of the AV regulations has a minimal impact on ridership. However, when interacting with other variables, such as race, political ideology, and access to AV information, this impact is revealed. Specifically, the increase in the likelihood of riding the AVs was primarily influenced by higher education levels, higher income levels, access to AV information, and residence area. The study provides an overview of the influence of government regulation on AVs and can be a good tool for policymakers, as it covers a large geographical area.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101601"},"PeriodicalIF":3.3,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145004659","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 scope focuses on metropolitan areas where traveling distances from truck depots are feasible. The study considered both the initial cost and running costs, including fuel, maintenance, and insurance, utilizing simulation to account for uncertain factors such as diesel and resale prices, particularly the total cost of ownership comparison between BEVs and ICEVs in Thailand. A Monte Carlo simulation was employed to account for the uncertainties associated with specific parameters. The results showed that the current situation of BEV trucks for 6-wheel 15-ton did not provide a reasonable cost compared to the investment and operating costs of the same model of ICEV truck. However, in the sensitivity analysis, if the government could support the BEV truck manufacturer or subsidize the purchase price to the user by at least 30% with a daily demand of 150 km, BEV trucks could become more attractive than ICEV trucks. In addition, if customers agree to pay more for the trip rate of 30% than the standard rate of ICEV, BEV would be more attractive than ICEV at 130 km as well.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101600"},"PeriodicalIF":3.3,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145010470","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}

This paper helps to fill this gap by providing a high-level quantitative assessment of the extent to which overnight train services in Europe would need to be expanded in order for them to make a substantive contribution to transport decarbonisation. It describes the historical development of overnight trains in Europe, and reviews previous research on this relatively neglected transport mode. It then shows through an assessment of intra-European aviation traffic in 2022–23 that while approximately 35% of this traffic is on routes which could feasibly be served by overnight trains, several hundred additional overnight train services would be required to accommodate even 10% of current air passengers. On average only 3–4 daily return overnight train pairs per year have been added to the European network in recent years despite their supposed revival. Rolling stock availability is currently a key constraint on the expansion of overnight train provision. If overnight trains are to play a meaningful role in the decarbonisation of long distance transport, coordinated large-scale government investment in rolling stock could be necessary to facilitate a step change in service levels. Despite this, overnight trains may still provide the most viable option for providing low-carbon travel on many flows in Europe.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101599"},"PeriodicalIF":3.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144989023","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}

Researchers and practitioners have posited that this gap may exist for a range of reasons, including: that the fleet electrification is not economically rational, that the needs of fleet operators are too diverse for current market offerings, or that targeted government interventions for this segment are lacking. We conducted a survey (n = 68) of small fleet operators in British Columbia, Canada and categorized the responses into barriers related to cost, incompatibility (real or perceived) and availability. Current EVs are incompatible with the operational needs of some respondents but our results show that, in many cases, the incompatibility is perceived and EVs could meet the stated requirements of such small fleets. We also observed that common customizations to (or “upfitting” of) fleet vehicles can be readily applied to EVs, but specialized use cases must be produced by the manufacturer—which may be a supply-related barrier. We also used a total cost of ownership (TCO) to demonstrate that while economic rationality is generally stronger for lighter duty class vehicles, small fleets that drive longer distances have a greater advantage in electrification. Our findings suggest that government intervention targeted at small fleets, such as bulk purchasing programs, could increase the adoption of EVs in this segment when coupled with purchase incentives. This gap could potentially be filled by local agencies, which can play a critical role in brokering trust between parties involved by being the middle actor at the boundary of government, suppliers, and customers. Lastly, we observe that small fleet operators display some understanding of the TCO of EVs. Incorporating an educational component into a bulk purchase program, as observed in other successful procurement arrangements that we review, could enhance the confidence of fleet operators and ultimately, lead to further adoption.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101588"},"PeriodicalIF":3.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049403","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}

Here, we investigate the effects of a fare exemption policy implemented only during Sundays in São Paulo’s bus transportation network, active since December 2023. As São Paulo is one of the largest metropolises in the world, we approach the analysis by adopting a complex network model that takes into consideration the spatial architecture of bus routes along districts. Our findings indicate a statistically significant impact of the fare exemption on both weekday and Sunday travel patterns. Evaluating travel pattern variations and considering our complex network as a spatial interaction model, we could identify hotspots where changes in daily passenger volume were more significant, finding that regions where bus transportation is not considered the main mode did not show signs of change in modal choice behavior.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101595"},"PeriodicalIF":3.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145004662","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}

Drawing on national innovation system theory and the demand-pull and technology-push framework, the research investigates the impact of three key enablers—technology capability, innovation input, and government incentives—on the level of stakeholder participation in transport infrastructure technology development. The results show that national technology capability has a direct positive relationship on stakeholder participation and mediates the indirect effects of innovation input and government incentives. High government support and sustained innovation efforts translate into stronger technological capability, which leads to a higher level of participation, implying the technology-related factors’ ability to mitigate risk and improve feasibility to stakeholders. High relations are also found between government incentives and innovation input. The research has significance in exploring transport infrastructure development from a novel technology-related perspective, which could provide policy implications for policymakers and decision support for investors when participating in projects to progress the transport infrastructure technology level.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"22 ","pages":"Article 101598"},"PeriodicalIF":3.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049406","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}

From a traffic engineering perspective, this study first aims to answer the question “how much modal shift it requires to counterbalance the impact of road space reallocation on network traffic flow” by conducting a microscopic traffic simulation case study. The city center of Zurich together with the E-Bike City (EBC) network designed in <span><span>Ballo et al. (2024)</span></span> is selected for the case study. Through analyzing the changes in origin–destination travel times and network fundamental diagrams, it is first found that congestion level increases significantly in the EBC network with minimal modal shift due to the reduced queue storage space on the roads for cars. In comparison to the situation in the status-quo network, a policy goal of an over fifty percent modal shift is required to mitigate the negative impact on traffic performance. However, congestion can be completely prevented in the large modal shift scenario by better utilizing the capacity of the bike lane network. The findings showcase a possible transition pathway toward a sustainable urban road environment and its outcomes for policymakers.
