These technologies have the potential to revolutionize shipping operations by enhancing efficiency and promoting environmental sustainability. A comprehensive study was conducted to assess the potential impact of e-Navigation on shipping companies, with a particular emphasis on the perspectives of Hydrographic Offices (HOs). The analysis is predicated on a survey that was conducted by HOs in 43 distinct countries. As they have accumulated a wealth of knowledge and experience in the development of S-100, HOs are uniquely positioned to evaluate the practical implications of these technologies. The S-100 framework was specifically examined as a case study within the broader context of e-Navigation in order to develop a more profound comprehension of its applications and impact. The insights obtained from this study can be used by policymakers to develop regulations and frameworks that facilitate the adoption of e-Navigation technologies, thereby guaranteeing the sustainable and efficient evolution of the maritime industry. The operational implications of navigational technologies are assessed in this study, which is a critical resource for policymakers, institutions, and shipping companies to inform future decision-making. Stakeholders can more effectively navigate the future of shipping operations by incorporating e-Navigation operational insights into maritime policy.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101331"},"PeriodicalIF":2.4,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142703714","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}

However, pedestrians are vulnerable road users and account for a significant number of traffic accidents worldwide. Characterizing pedestrian behavior is crucial for enhancing safety and comfort. Several factors influence pedestrian behavior, including personal, situational, social, and cultural aspects. It is essential to consider these factors collectively for accurate predictions. Previous studies have highlighted the importance of cultural and location-specific influences on pedestrian behavior, yet many have focused primarily on risk perception, often neglecting the role of social interactions during street crossings. This study analyzes pedestrian behavior at a crossing in two culturally diverse cities: Bucaramanga in Colombia and Guimarães in Portugal. The research emphasizes the social and operational factors that affect how pedestrians cross streets. Specifically, it explores how cultural and social differences in each city influence group walking speed and mobility. The study examines several factors, including walking speed, the distance between pedestrians (whether in groups or alone), and the impact of group size and gender composition. The results demonstrate that informal rules and cultural context significantly impact pedestrian behavior during various crossing phases. Notable variations were observed in pedestrian speed before crossing and the spatial organization of groups during the crossing. To enhance road safety, interventions should consider these cultural factors and include educational programs that promote safe practices. This study contributes to a better understanding of how social factors influence pedestrian behavior and provides valuable insights for modeling pedestrian behavior, optimizing pedestrian facilities, and developing effective strategies for improving road user safety.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101333"},"PeriodicalIF":2.4,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142703713","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}

The Cross-Efficiency Method (CEM), derived from DEA, addresses these limitations. However, recently, the conventional CEM has been considered for further improvements. Firstly, it assumes equal significance for all Decision Makers’ (DMs) viewpoints by using the arithmetic mean for overall cross-efficiency calculation, which is unrealistic. Secondly, it does not consider DMs’ viewpoints psychologically. Thirdly, it does not often consider achieving consensus through efficiency calculations. Finally, it includes all viewpoints for efficiency calculation, regardless of their relevance, which can bias the results. Thus, the primary objective of this study is to develop hybrid <em>Q</em>-based CEMs to address these shortcomings. Also, this study is the first to use the <em>Q</em> methodology to address the limitations of traditional CEM. The <em>Q</em>-based aggressive and benevolent CEMs, known as QACEM and QBCEM, provide policymakers with several advantages. Firstly, they allow for the exclusion of irrelevant viewpoints from the analysis. Secondly, they enable the calculation of each DM’s appropriate contribution. Thirdly, they capture DMs’ psychological preferences using the <em>Q</em> methodology. Lastly, they facilitate consensus-building by extracting group perspectives through factor analysis. The <em>Q</em>-based CEMs were utilized to assess the performance of 25 Iranian international airports and demonstrated their effectiveness. Selecting the optimal loading factors of 0.6 and 0.7, QACEM and QBCEM included the highest possible number of DM’s viewpoints, which were 24 and 25 respectively. The results indicate that airports BND, AWZ, and OMH demonstrated satisfactory performance.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101332"},"PeriodicalIF":2.4,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142703716","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}

One of the most important drawbacks of electric vehicles is their low range. With the studies carried out in battery technology, it is aimed to increase the range distance. However, when the range distances of today’s electric vehicles considered, vehicle owners demand to recharge as soon as possible on long distances. While electric vehicle owners have the opportunity to perform many activities during charging in the city, they do not have such opportunities in intercity traffic such as on highways. For this reason, the waiting times for charging stations on intercity roads should be reduced and their availability should be increased. In this study, the Istanbul-Ankara highway, one of the most frequently used highways in Turkey, is considered. It is aimed to reach the minimum number of charging stations that meet the assumptions. The capacited range coverage location model is used to solve a real-life problem by considering the distances between fuel stations and resting facilities on this highway. With the modifications made to the base model, the obtained model has become more suitable for use in real life problems. With the results obtained, it is stated in which gas station or resting facility charging stations should be installed on the highway.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101320"},"PeriodicalIF":2.4,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652564","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 statistical model is used to analyze how the port cargo throughput movement in Mexico is affected by changes in the level of industrial activities in both Mexico and the United States, and to generate a projection of the national port cargo throughput movement for the upcoming years. To achieve this, a multivariate time series analysis with vector autoregressive models was constructed using monthly frequency data from 2010 to 2022. The results of the autoregressive model indicate that the proposed macroeconomic variables have a Granger-causal effect on port cargo throughput movement. It was also found that an incremental shock from the U.S. economy has a positive effect that is transmitted temporarily during the first six immediate months, while changes in the national economic activity also have a temporary positive effect, but only during the first immediate period. Traditional forecasting performance metrics are used to evaluate the effectiveness of the proposed model.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101322"},"PeriodicalIF":2.4,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652563","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}

Data are scarce, heterogeneous, often old and expensive to collect. This research looks at new ways to collect urban freight data and make that data available to both policy-makers and academia. Three case studies are examined: Rotterdam, the Netherlands; Brussels, Belgium; and Barcelona, Spain. They help identify new sources of data from traffic and parking policies: automated number plate recognition cameras, an on-street delivery smartphone app, and a truck pricing scheme. Both the context in which new data sources of interest to urban logistics are produced, and the level of appropriation of these data by local stakeholders and the research community are examined. We then construct an analysis grid to evaluate the diversity of systems (technical and socio-technical) producing data relevant to urban logistics. This analysis framework can be used to facilitate comparisons between data sources and thus help future case studies. In the three cases, we found that local governments use the data more than researchers do. The issue of data dissemination raises questions about costs (who is to bear the cost of storing, maintaining and extracting data sets?) as well as regulatory questions. We conclude that local administrations should be encouraged to work towards harmonizing data collection methods and data sharing conditions in order to improve the quality and comparability of the data. Cities in countries with little access to new sources of data, such as France for regulatory reasons, should try to find ways to create data source opportunities.

Using a novel method of moment quantile regression (MMQR), this study investigates the impacts of EV adoption, environmental policy stringency, economic growth, commercial transportation services, and renewable energy on transport sector’s CO₂ emissions. The results indicate that the influence of EV adoption on transport emissions varies across different quantiles. While the adoption of EVs is not significantly associated with transport CO₂ emissions at the high quantile level, a significant relationship is found in the low and middle quantiles. More importantly, transport CO₂ emissions demonstrate a significant negative correlation with the stringency of environmental policies across all quantiles. Our results highlight that the combined impacts of EVs and stringent environmental policies are more pronounced in alleviating carbon emissions compared to their individual effects. These findings hold intriguing implications for policy discussions, suggesting that EVs, along with rigorous environmental policies, offer a viable pathway to mitigate carbon emissions in the transportation industry. Furthermore, this study confirms the existence of an inverted U-shaped Kuznets curve in the context of the relationship between economic growth and transport-related emissions, implying that policies promoting economic growth might be seen as environmentally sustainable in the long term.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101330"},"PeriodicalIF":2.4,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652632","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}
