We present a case study considering the simultaneous use of road and rail transport to replenish a distribution center in Belgium from a supplier in Spain, aiming for a modal shift from road to sustainable rail transport. Product demand is non-stationary, meaning the demand distribution changes over time. Although the underlying demand distribution is not directly observable, demand observations provide partial information. We apply the synchromodal replenishment policy proposed in Yee et al. (2024) that combines a committed, stable rail order with flexible short-term orders on rail and road. The short-term orders are based on inventory levels and partial information about the non-stationary demand. The case study demonstrates the value of adding short-term flexibility to rail orders to induce a modal shift. Our analysis shows how the proposed policy improves the modal shift compared to a benchmark policy without flexible rail orders. The retailer can reduce the carbon footprint of its replenishments without compromising service levels or costs. We also show how offering the flexible rail option increases the rail operator’s revenues. These findings highlight the potential of synchromodal replenishment with flexible rail orders to facilitate a modal shift.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101342"},"PeriodicalIF":2.4,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093454","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}

One of the reasons for this growth is the high demand for air travel coupled with low entry barriers to the industry. Despite this growth, airports’ operational and commercial aspects remain complex. For instance, terminal overcrowding is a significant problem, potentially causing flight delays and passenger dissatisfaction. Consequently, airport planners and management must employ effective customer service strategies. Systems modeling has emerged as a cardinal approach in the aviation industry to address these challenges. This study adopts the system dynamics approach to improve the overall service performance of an airport terminal. For testing ground, we have considered one domestic airport located in Bangladesh. First, different service policy categories were defined for the airport. Subsequently, the service levels were determined and the impact of the proposed policies on service quality and passenger volume was assessed. By implementing better service policies, the time required for passengers to complete various procedures from entry to the final boarding gate decreased by up to 50.53 %. Therefore, better service policies improve the quality of service and minimize the risk of passengers missing their flights. The insights gained from this study can help administrators make informed decisions for improving the service at airport terminals.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101345"},"PeriodicalIF":2.4,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093453","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}

Road transportation is the most commonly preferred mode for transporting hazardous materials domestically. Enhancing the safety of hazardous material transportation operations by road is a primary concern for the sector. To prevent hazardous materials (hazmat) road transportation accidents, it is essential to gather information from accident reports, including accident precursors and outcomes, to improve safety. However, research investigating accidents related to the transportation of hazardous materials on highways is limited. This study aims to determine sequential rules based on temporal dependencies between accident precursors and outcomes, unlike previous studies, using hazmat road transportation accident records within the scope of inland transportation in Turkey from 2015 to 2020. The TRuleGrowth algorithm, a significant task in data mining, was used to analyze accidents and present 75 sequential rules for the most frequently occurring combinations of outcome variables, including injury, fatality, injury and fatality, and damage level.

To address this knowledge gap, this study examines access to the regional bus system of Minas Gerais state, Brazil via a new index adapted to the minimal data typically available at the regional scale. Within Minas Gerais, major urban areas and some of their neighboring municipalities had the highest levels of bus access. Conversely, 49 of 853 municipalities (5.7%) lacked access to the regional bus system entirely. These inaccessible municipalities had smaller populations and were located on or near state borders, while municipalities with high levels of transportation access tended to have higher population densities, gross domestic product (GDP) per capita, and concentrations of paved highways. These results confirm that regional bus access is associated with the demographic, economic, infrastructure, and spatial characteristics of municipalities. Ultimately, this study reveals significant disparities in regional bus access throughout Minas Gerais, providing a foundation for further research on transportation accessibility and mobility in Brazil while demonstrating methods suitable for analyzing regional transportation access in low-data contexts around the world.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101348"},"PeriodicalIF":2.4,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093465","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 study uses two robust regression models to answer two research questions related to the key metrics of pollutant concentrations and long-term health benefits following LEZ implementations. The two pollutants, Nitrogen Dioxide (N<em>O</em><sub>2</sub>) and Fine Particulate Matter (<em>PM</em><sub>2.5</sub>), were examined with the “openair” software in R, which is used to analyse trends in air pollution. The impact that different policies have on several health metrics were also examined through data collated from literature reviews. The results obtained after analysing London’s LEZ (2008) and ULEZ (2019) were then used to evaluate the viability of Manchester’s Clean Air Plan. The results show that there is statistically significant evidence of LEZs curbing pollution levels, which in turn contributes to long-term health benefits. It is concluded that the current trajectory of Manchester’s air pollution policy, which falls short of having an LEZ, is likely not impactful enough on pollutant concentrations and health, especially in relation to <em>PM</em><sub>2.5</sub> levels. Future research at planned time intervals is suggested for modelling the extent of the impact of Manchester’s Clean Air Plan.

Different factors influencing cost overruns were considered: project size, type, planning duration, start year, and historical policy changes. The results revealed that the general patterns of cost overruns observed internationally do not apply to Switzerland: projects tend to overrun estimated costs during the planning phase but underrun during the construction phase, leading to accurate overall cost estimates (4.7% median overrun). Projects exhibited large and asymmetrical cost accuracy ranges throughout the planning and construction phases.
