This paper provides a study of the different alternatives that are being considered in the 5G-ROUTES project to establish seamless 5G connectivity in a maritime environment both from an architectural point of view and also from the definition of field trials to evaluate the performance and dependability of the proposed solution. As expected, the main challenge in providing 5G connectivity on the sea is to provide coverage over large areas of open water. Thus, as a starting point, this paper presents a measurement campaign that was conducted to assess the current coverage in the Baltic Sea, which concluded that the current terrestrial networks cannot guarantee sufficient coverage. Next, the solution architecture and trials proposed by 5G-ROUTES are described, which are based on the integration of satellite and leading-edge multi-hop connectivity in 5G networks. Utilizing satellite backhaul can potentially overcome the connectivity challenge from the terrestrial domain to the maritime domain, while multi-hop connectivity ensures that coverage is extended among the different ships that are navigating the sea. Furthermore, this paper describes how the project will evaluate, in field trials tailored to this maritime environment, common connectivity key performance indicators (KPIs) such as latency, throughput, availability and reliability. This paper concludes by providing a vision for applying the obtained results and insights to maritime transportation and other remote areas where the deployment of a suitable 5G infrastructure may be challenging or costly. The findings will be used to guide the design of future 5G networks for marine applications and to identify the most effective methods for providing secure and dependable communication in a maritime setting.

The international maritime sector plays an important part in contributing to the global sustainable economy and plays a significant role in achieving sustainable development goals. A variety of regulations and standards power the sustainability management of the global maritime sector, including the United Nations’ Sustainable Development Goals and the European Union’s new draft European Sustainability Reporting Standard. Limited research on the potential contribution of maritime policy-making to support sustainable development has led the sector to face multiple challenges. In this study, we analyzed how local policy-making can impact international goals and global sustainable development based on comprehensive datasets of 143 maritime companies. The study recommends the incorporation of sustainability dimensions of the maritime sector into all levels of policy-making and supporting the policy implementation with the local maritime governance structure. A maritime country should have strategic planning objectives that embrace maritime affairs and use the interactions identified between local development and the maritime sector. We propose a framework for maritime policy-making that supports sustainable development. A maturity model for sustainable development in the maritime sector was developed. The results can be used as guidelines for policymakers in planning sustainable development in a maritime country.

In policy-making, the design of a policy is considered to be one of the most significant steps. A well designed policy will be able to solve sectoral problems across stakeholders as well as support the competitive development of the entire economy. Enterprises of the maritime sector have been influenced by environmental, social, and governance (ESG) changes with the push coming from financiers, insurers, regulators, and customers. To meet the ESG challenges and utilize the benefits ahead, they need to be addressed in the new policy design processes. The specificities of a maritime sector as well as science-based policy-making framework are the fundamentals of successful maritime policy development. Estonia is located on the eastern border of the EU, and has always aimed to be a maritime state. National maritime policy has been adopted (2012–2020) and currently, the Estonian Transport and Mobility Master Plan incorporates maritime aspects. Actors of the maritime sector have remained dissatisfied and advocate the reinstatement and redevelopment of Estonian maritime policy. The aim of this study was to present a framework for the design of maritime policy that uses maritime economics, ESG performance goals, and policy design analyses as inputs. As a result, a maritime policy design framework is proposed.

5G systems are capable of facilitating remarkable technological advances and promoting sustainability in Internet-of-Things-centric fields, such as the Transport and Logistics (T&L) sector and applications in Connected-and-Automated Mobility (CAM). The current article provides an overview of the latest developments in the applications of the 5G mobile network standard in CAM and is specifically focused on analyzing existing and potential applications within European T&L corridors and subsequent markets. A focused marketplace analysis is conducteFd, highlighting the demands of commercialization clusters within European cross-border markets, as well as an analysis of how some of these demands can supplement the deployment of 5G products and services in the coming years. With the aim of providing a macro-level description of the landscape of 5G applications in CAM, the authors further discuss and classify the markets’ influencing factors according to the PESTEL framework, which is further enhanced to include the recent impacts of the COVID-19 pandemic and the war in Ukraine. The findings display that while 5G is a crucial underlying technology for the establishment of CAM, several factors, such as international security, political coordination at the EU level, and common technological standards across EU member states, will have a central role in the successful deployment of its applications.

The design, building and maintenance of national roads constitute a substantial part of the government budget. Taking into account the magnitude and importance of these investments, the expedience, efficiency and sustainability of roads are of great public interest and their per­formance should be measured. For performance assessment of roads or road sections it is important to gather data about different key performance indicators. Flexible pavements deteriorate under traffic loads and climate effects. This effect depends on the technology and materials of the road, but the greatest effects depend on traffic loads and volumes. Systems can be developed to give information about tire wearing and its impact on the pavement wearing. To ensure traffic safety, especially in countries with cold climate, it is very important to gather continuously data about tire tread wear. New technologies have made it possible to integrate the measuring of tire tread wear and tire type on roads continuously and present new opportunities to monitor and analyse conditions of tires. This paper is part of a road performance measurement system presenting a concept for input data collecting.

The structure and functioning of network industries have a great effect on the well-being of society, being also prerequisites for economic growth and productivity. Social goals, industry trends, ownership structures, and the economic environment play an important role in the development of such networks. Most network industries enjoy a dominant position on the market. Their performance is steered by national regulatory authorities via price control and quality requirements. For this the regulatory authorities need besides financial indicators feedback on the technical performance of the provided services. The vast development in sensing, data transmission, and collection technologies, as well as in analytical methods, has made it possible and feasible to acquire the needed feedback. Such comprehensive data enable to construct a performance measurement system to regulate, develop, and administer the networks. This paper explores the possibility of developing an overall technical performance index and presents a relevant concept. The suggested overall index would be an additional regulatory tool to evaluate the performance of network industries and their compliance with consumers’ requirements. The aim of the proposed concept is to establish empirically verifiable feedback between a given state of technology, state of institutional governance, and the performance of network industries.
