The paper investigates whether refrigerated diesel light commercial vehicles (D-LCVs) could be substituted by refrigerated electric LCVs (E-LCVs) or hydrogen LCVs (H2-LCVs), considering both their economic and logistics performances. The economic performance is evaluated via the total cost of ownership (TCO) methodology, while the logistics one is estimated via a multi-agent simulation model. If LCVs are operated in urban contexts, we find that both alternative powertrains exhibit operational parity versus D-LCVs, irrespective of the weather conditions. In terms of TCO, however, only E-LCVs are almost competitive with D-LCVs, while H2-LCVs are by far costlier. If LCVs are used to distribute refrigerated goods in regional contexts (with longer travel distances), E-LCVs show lower logistical efficiency than D-LCVs under normal conditions, further exacerbated in extreme weather, although they have better TCO metrics. On the contrary, H2-LCVs achieved similar logistical efficiency than D-LCVs but continue to show very poor economics.

Developing green passenger transportation is beneficial for reducing air pollution emissions and improving the living environment of residents. However, research that comprehensively considers the two components of intercity travel, intercity transportation and intra-city connecting transportation, remains insufficient. To design an intercity green travel strategy with a continuous green guidance effect, this paper develops a tripartite evolutionary game model, with the government, high-speed rail enterprises, and intra-city public transportation enterprises as the key players. From the perspective of the entire intercity travel process, we analyze the evolutionary stable strategies of game participants and the applicable scopes of these strategies, and discuss the green travel strategies suitable for participants to adopt in different periods through case simulation. The simulation results show that (1) the cost to the government of ignoring passenger transport environmental protection significantly influences its decision-making. (2) Short-term strategy is relatively more advantageous. At this time, the government's subsidy support policy for the green passenger transport enterprises is also more effective. (3) In the long term, the government's choice of strategy will only affect itself. Green passenger transport companies will only implement green travel measures if these measures conform to the laws of the market economy—i.e., if the companies can benefit from them. This article concludes that the green travel subsidy strategy is suitable for the early intervention stage and provide corresponding policy recommendations. The research findings can provide a basis for the government to formulate implementation strategies for passenger transport environmental protection measures.

The maritime transport sector is characterised by unique dynamics, including the ease of crew exchange and the increased use of standardised languages by seafarers. These factors have led to greater multinationalism among ship crews, which presents several managerial, cultural and operational challenges. This study examines the factors, drivers and barriers affecting the integration of professional seafarers into the global maritime labour market under multinational working conditions. The study introduces a ‘harmony’ variable, derived from six attitudinal items, as a proxy for seafarers' adaptability to multinational crew environments.
A mixed-method design was employed, integrating quantitative analyses with qualitative insights to provide a comprehensive understanding of multinational working. A hierarchical cluster analysis was conducted to classify the respondents according to their harmony values. The classification of seafarers according to harmony scores was followed by the analysis of quantitative data from 322 respondents and qualitative data from 125 respondents, respectively. The findings indicate that there were no significant differences in the duration of multi-national working for seafarers at varying levels of harmony. Moreover, an analysis of the factors that contribute to the duration of multinational work revealed that marital status, competence, and raising with maritime culture were significant predictors.
In the context of multinational working, it has been observed that seafarers tend to express concerns regarding their English language proficiency, professionalism, and cultural properties. However, the participants identified several challenges that lie beyond the capabilities of seafarers, including the need for government support, global marketing, and accreditation. These findings underscore the need for policy interventions in maritime education and international cooperation to prepare seafarers for multicultural working environments. Therefore, policymakers should undergo critical reorganizations in maritime education and training to integrate their mariners with the global labour market.

Dry ports are a strategic necessity in Türkiye's Aegean Region due to increasing demand and limited port capacity. This study suggests an integrated, sustainability-oriented approach that combines Geographic Information Systems (GIS), Multi-Criteria Decision Making (MCDM) methods, and scenario-based mathematical optimization for dry port location in the Aegean Region of Türkiye. First, 17 spatial and non-spatial criteria derived from expert surveys and literature review were weighted by the Best-Worst Method (BWM). The criteria were transformed into suitability maps in a GIS environment. Second, the candidate areas were assessed with a two-objective optimization model under different scenarios subject to certain constraints. Based on the model results used in the study, suitable areas were identified as Aydın-Karpuzlu, İzmir-Tire, and Denizli-Denizler. The analyses conducted within this study are not limited to spatial analysis. This study, which has the potential to guide strategic decision-making processes, can be considered a very powerful practical tool for decision-makers.

Adopting battery electric vehicles (BEVs) is critical for achieving sustainable transport and reducing carbon emissions, yet obstacles such as range anxiety, limited environmental awareness, and resistance to innovation continue to impede uptake. This study investigates how social influence, environmental concern, face consciousness, range anxiety, and consumer innovativeness shape BEV purchase intentions, with attitude as a mediator and anthropocentric value orientation as a moderator. Partial least squares structural equation modelling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA) were used to analyse 481 survey responses. Results show that attitude mediates the effects of all antecedents, while high anthropocentric value orientation amplifies its influence on purchase intention. FsQCA identifies multiple causal pathways to high purchase intention, particularly those combining high levels of face consciousness, attitude, and anthropocentric value orientation with low range anxiety. These findings highlight the importance of integrating personal and environmental drivers into transport policies, providing evidence to support strategies that accelerate BEV adoption.

Consumer acceptance is crucial for promoting new energy vehicles (NEVs), which are reshaping the traditional automotive brand landscape. This study investigates how consumer perceptions—specifically, perceived fit (brand image and product category fit) and brand trust—affect acceptance of NEV brand extensions across varying extension distances. Analysis of data from 1058 respondents reveals that perceived fit and brand trust significantly drive acceptance, with extension distance moderating these effects: as distance increases, the importance of brand image fit decreases, whereas brand trust becomes significantly stronger. These findings inform strategies for NEV promotion, emphasizing how brands can leverage consumer perceptions and extension theory while managing extension distance.

Mobility-as-a-Service (MaaS) promises to transform urban transport, but its success in developing cities hinges on understanding how diverse users respond to specific service features. Comparative analyses between user groups, particularly those involving car versus public transport users, are limited, especially in developing countries. This study aims to assess the likelihood of adopting MaaS conditional on the presence of its core defining features, highlighting their role in enhancing service quality and passenger experience among 1243 private car and public transport users in Greater Accra, Ghana. Using ordinal logistic regression, we evaluate how seven core MaaS features, including real-time information and multimodal trip planning, shape adoption likelihood, and how this varies by socio-demographics, travel behaviour, and prior MaaS knowledge. The findings reveal strong support for real-time information and accessibility elements across user groups, while dynamic pricing and incentives, as well as multimodal trip planning, elicited scepticism, particularly among car users. Adoption likelihood was shaped not only by feature type but also by demographic characteristics: for instance, women and frequent public transport users showed greater interest in accessibility and seamless ticketing and payment features, while higher-income car users were more favourable to monthly subscription models. Findings have practical implications for inclusive mobility planning and equitable MaaS deployment in the Global South.

Ports play a critical role in global trade and logistics, yet their efficiency must be assessed not only by operational performance but also through environmental sustainability metrics. This study evaluates the operational and environmental efficiency of Japan's top ten container ports using data envelopment analysis, combining both slacks-based measures and the undesirable output models. The research results show that Tokyo, Yokohama, and Kobe ports perform best in operational efficiency, with efficiency scores of 1.000; while Tomakomai and Hakata ports have low scores of 0.233 and 0.363, respectively, due to insufficient infrastructure utilization. In terms of environmental efficiency, Kobe and Yokohama ports also perform well, with efficiency values of 1.000, while Tomakomai Port has the lowest environmental efficiency of only 0.084. The result found that high-efficiency ports usually have advanced automation equipment and green infrastructure, while low-efficiency ports face problems of inefficient energy utilization and high emission intensity. The dual efficiency evaluation framework constructed in this research provides port managers and policymakers with a quantitative basis for green port transformation and supports Japan's sustainable port development path planning under the decarbonization goals.

This study presents a comprehensive Quantitative Risk Analysis (QRA) framework for assessing road transport accidents involving dangerous goods in Turkiye. The proposed methodology integrates national accident statistics, scenario-based event tree modeling, and ALOHA software/ correlations for consequence and impact assessment. Three representative routes in İzmir were selected as pilot areas to evaluate accident frequencies, physical impact zones, and associated individual and societal risks. Results indicate that LNG and LPG transport pose the highest risk levels, with scenario frequencies exceeding the regulatory threshold (1 × 10−4/year). Population exposure analysis revealed that social risk varies significantly with local demographic density. Sensitivity analyses confirmed that both the frequency of the initiating event and population distribution are critical determinants of total risk. The study presents a data-driven, nationally adapted QRA model aligned with Turkish transport infrastructure and regulations, providing a robust decision-support tool for improving road safety and emergency preparedness in dangerous goods logistics.

Are the most cost-efficient train lines providing the best service? This study demonstrates that efficiency models often misidentify operational success, rewarding lines with significant service quality deficits. Based on a granular analysis of 174 line-year observations across 58 French regional railway lines, we propose and apply a new efficiency framework. By incorporating essential Quality of Service indicators (punctuality, regularity, frequency and crowding) into the evaluation, we reveal a fundamental reshuffling of performance rankings. Our findings show a clear divergence: cost-efficient lines with poor service are penalized, while lines delivering high-quality service see their performance scores improve significantly. The analysis further identifies the distinct characteristics of lines that experience the greatest changes in rank. As France moves towards competitive tendering in the rail sector, these results carry significant policy implications. A sole focus on cost-efficiency risks incentivizing service degradation. This research offers Public Transport Authorities a robust, quality-aware tool to facilitate more accurate performance diagnostics, identify benchmark lines, and ultimately foster a system that prioritizes both economic viability and passenger welfare.

The analysis further identifies the distinct characteristics of lines that experience the greatest changes in rank. As France moves towards competitive tendering in the rail sector, these results carry significant policy implications. A sole focus on cost-efficiency risks incentivizing service degradation. This research offers Public Transport Authorities a robust, quality-aware tool to facilitate more accurate performance diagnostics, identify benchmark lines, and ultimately foster a system that prioritizes both economic viability and passenger welfare.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"65 ","pages":"Article 101590"},"PeriodicalIF":4.4,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145885181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
