Recent scientific reports at European level suggest that combining passenger and freight flows (commonly referred to as <em>integrated transport</em>) could be an effective strategy to promote sustainable and energy-efficient FLM transport. Public transportation usually covers most populated areas of the city, making it suitable for this kind of dual operation. Despite their potential, integrated systems have not been extensively explored. This study develops an algorithm that optimizes the location of dual-purpose stops within Bilbao’s bus network in Spain to facilitate such integrated operations through a combination of evolutionary algorithms. The real multi-objective optimization scenario proposed as a case study formulates and solves the problem of balancing the benefits and inconveniences of incorporating such a combined service. The design of the system’s operational aspects involves the integration of the real scenario service characteristics into the problem formulation, as well as an analysis of local planning documents. The system’s performance is assessed and compared to existing public transport and freight systems, considering the Pareto trade-off of two key factors for the design of the service: the impact of the integrated transport service on the passengers’ quality of service and the mileage required to deliver goods to their corresponding destinations. Our findings indicate that operational benefits and energy savings can be achieved gauging the level of inconvenience introduced in the passenger transportation service.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"36 ","pages":"Article 101887"},"PeriodicalIF":3.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385177","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}

Supply chain management is an integral part of international trade. The inland freight transportation system is becoming demand-driven, efficient, real-time information provider, and time–cost bound. Now, synchromodal is getting priority in considering as a modern freight transportation system to improve flexibility and reduce the freight cost and passage time in a given container supply chain technology. It is essential to create multiple options for choosing nodes and modes by carrier and users for managing inland freight movement from seaport to last mile or vice versa. A mixed research method is applied to know the current position of the node, mode, and the aptitude of stakeholders to adapt synchromodality in Bangladesh. The findings and originalities of the research are insufficient freight infrastructure in terms of required nodes and modes, non-availability of national logistics policy, and application of an intelligent transportation system (ITS) for an integrated freight transportation system in Bangladesh. The impact of the research is the upgradation of the freight transport model by combining intermodal, multimodal, and synchromodal to facilitate the container supply chain from the seaport to the hinterland and maximum utilization of transport nodes and modes by carriers for the interest of port users in reducing freight transport time and cost. Finally, a synchromodal freight transportation system is required for Chattogram Port to set a real-life logistics solution for the port users.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"36 ","pages":"Article 101898"},"PeriodicalIF":3.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385234","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}

However, despite increasing vehicle diversity and supportive policies, adoption remains limited due to organizational inertia, sunk costs, and resistance to change. Short-term pilot projects, while useful for testing feasibility, often fail to capture the evolving and context-specific dynamics of fleet integration. To address this gap, we introduce and evaluate a novel long-term trial framework implemented across multiple German regions over a 12-month period. The framework embeds vehicle trials into daily operations and combines tailored onboarding, sustained engagement, and structured reflection phases. This article makes three core contributions. First, it advances both academic and practical understanding by introducing a reliable and transferable framework for long-term fleet transformation that functions as an organizational learning device. Second, it uncovers context-specific and time-sensitive challenges of integrating LEVs and cargo bikes, as shown through five stylized cases across logistics, manufacturing, services, and craft sectors. Third, it conceptualizes three learning-based pathways of organizational commitment to fleet transformation: fleet expansion, vehicle substitution, and purchase prevention, through which long-term trials can support learning-based fleet reconfiguration, including normative learning reflected in the strategic reframing of alternative vehicles. The findings highlight the value of long-term trials in supporting adaptive and real-world transitions that extend beyond the scope of short-term studies. By fostering deeper organizational learning and aligning vehicle solutions with operational realities, the framework establishes critical conditions for sustained adoption and contributes to the broader transition toward more sustainable transport practices.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"36 ","pages":"Article 101897"},"PeriodicalIF":3.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385233","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}
