The findings provide clear evidence that airline subsidies significantly boosted regional air passenger flows, while airport subsidies had limited influence. This research is novel and valuable as it empirically evaluates the effectiveness of the ETC scheme in supporting New Zealand’s domestic aviation during the post-lockdown period, an area that has received little attention in prior studies. It contributes to the growing body of literature on COVID-19-related aviation policies, specifically their role in sustaining regional aviation markets. While this study focuses on New Zealand’s unique context, its implications extend to policymakers globally, offering insights for designing effective aviation subsidy policies that promote regional aviation recovery and growth in the post-pandemic era.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101405"},"PeriodicalIF":2.4,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563013","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}

By leveraging detailed emissions data and forecast scenarios up to 2050, the research quantitatively assesses the potential reductions in greenhouse gases and other pollutants under current and upcoming emission regulations. The findings indicate significant environmental benefits from stricter emission standards and a transition towards electric and autonomous vehicle technologies, with notable reductions in NO_x, particulate matter, and CO₂ emissions. However, the study highlights the critical dependence of these outcomes on integrating vehicles with cleaner electricity grids and higher market penetration rates of advanced technologies. The research provides critical insights into the effectiveness of emission regulations and technological advancements in reducing vehicle-related pollution to achieve the EU’s climate targets by 2050.

This reliance on motorcycles as the predominant mode of transport demands attention, as it conflicts with the principles of sustainable mobility. The present study collected survey data from 430 respondents in order to explore this phenomenon. The study then examined socioeconomic conditions, mobility patterns, and behavioral factors among the respondents using the theory of planned behavior (TPB) framework, with the structural equation model (SEM) serving as the analytical tool. The findings of the study reveal that cost savings, time efficiency, and societal factors exert a significant influence on the high reliance of low-income communities on motorcycle use. These findings underscore the practicality and affordability of motorcycles, which, in the absence of viable alternatives, become the primary mode of daily commuting.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101404"},"PeriodicalIF":2.4,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143550394","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}

These services are provided by motorcycled food delivery riders (FDRs), who are often informally employed, poorly paid, and work under time pressure, which might increase the risk of traffic crashes. Until now, few studies have been concerned with the effects the Covid-19 pandemic has had on driving behavior, especially for FDRs. Furthermore, it remains unclear whether work conditions and financial vulnerability could influence driving behavior. In addition, related studies have been conducted in Europe, but research in this field in South America seems to be lacking. Therefore, this paper aims to identify the antecedents of risky driving behavior for FDRs in Brazil during the Covid-19 pandemic. Therefore, an extended framework based on the protection motivation theory was proposed. Data were obtained from 295 FDRs and were analyzed using Partial Least Squares Structural Equation Modeling. The results showed that working conditions and financial vulnerability positively affect their driving behavior. Additionally, coping appraisal has a negative and significant effect on risky driving behavior. The effect of threat appraisal on risky driving behavior was found to be positive, which could be indicative of a typical behavior of young drivers. Therefore, FDRs perform a risky activity due to long working hours and the pressure for fast deliveries. Also, to meet short delivery time, FDRs adopt a risky behavior (red-light running, driving while checking cell phones and not using safety equipment).</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101403"},"PeriodicalIF":2.4,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520981","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}

To do this, a case study with company-specific data is implemented. The findings show, first of all, that the lead time plays an important role in whether D&amp;D occurs. Longer lead times exceeding the D&amp;D free time result in D&amp;D costs which increase the shippers’ TLC considerably. Second, the impact of D&amp;D on the TLC is shipping line dependent. Hence, shippers can limit the TLC increase by choosing shipping lines that offer more free time for intermodal transport. Third, increases in the warehousing cost component can result in higher TLC compared to the TLC when D&amp;D charges occur, suggesting that it might become more interesting for the shipper to store its goods in the container throughout the hinterland chain and thus pay D&amp;D instead of in a warehouse. These results, although case-dependent, give insights into alternative storage options throughout the chain and their costs for shippers as well as that incurring D&amp;D charges can be acceptable under certain logistics strategies.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"20 ","pages":"Article 101397"},"PeriodicalIF":2.4,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817808","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}

To accommodate changes in ridership patterns, it is important to consistently update knowledge of the factors that most influence a rider’s decision to use public transportation. Origin-Destination Direct Ridership Models are one of the methods used to accomplish this, as they examine the sensitivity of transit demand to changes across a series of explanatory variables. This study replicated a time-of-day, multi-level Origin-Destination Land Use Ridership Model (OD-LURM), previously developed using 2014 ridership data, with 2022 SmarTrip card data from the Washington, D.C. Metrorail System. Directly comparing model results from 2014 and 2022, the magnitudes of the effects of various determinants on Metrorail ridership were examined, considering three different groups of variables at the level of origin stations, destination stations, and OD-station pairs. The effects of the total number of jobs within a half-mile radius, parking users, parking capacity, bus line counts, and median household income on ridership in the AM peak, PM peak, and off-peak time periods were reduced compared to the previous study, sometimes drastically. The results also indicated a weaker model fit using the updated data. Overall, this replication study provides new context behind changes in post-pandemic ridership, and the results suggest persistent changes in travel behavior since the pre-pandemic period.
