Along with the increase in passenger flow, the number of private cars is also increasing. This paper discusses the highly relevant issue of determining the efficiency of mobility in the South Moravian Region, including both private and regional public transport. For the assessment, the study utilises a non-parametric DEA-CCR model. The objectives of the study are to (i) identify the main evaluation criteria of the transport efficiency for passengers, (ii) determine the frequency of single-transport usage and alternative combinations, and (iii) use DEA to identify an efficient transport design and discuss the suitability of the method for this transport issue. It has been observed that travel time and travel cost are the main criteria for passengers. These factors, along with the carbon footprint and frequency of transport usage, were incorporated into the analysis. Respectively, we chose time, cost, and carbon footprint as inputs, with transport usage as the output for the key variables for the DEA application. Despite walking having the lowest carbon footprint and cars having the highest, the results indicate that both are the most efficient modes of movement within the region. Furthermore, the public transport system in Brno and the regional transport in Blansko are classified as efficient based on analyses by individual municipalities. We discovered that neither the travel cost nor the carbon emissions deter individuals from using automobiles. As a recommendation, the cars stand out as a significant mode of transport, which necessitates a specific efficiency assessment based on different criteria. Moreover, while bicycles are recognised as a significant eco-mobility alternative, they are deemed inefficient due to their infrequent daily usage. The results of the DEA analysis indicate that urban and regional public transportation, as well as their combination, represent an inefficient mode of transportation for passengers (except Brno and Blansko). This suggests that regional and municipal authorities should support further development of public transportation, improve infrastructure for cycling and other micromobility options, advocate for greater emissions reduction, and promote broader public transport usage.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"19 ","pages":"Article 101358"},"PeriodicalIF":2.4,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093459","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}

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.

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.
