    Correlations Between Transportation and the Covid-19 Pandemic
    (AIP Conference Proceedings, 2022) Barberi, Salvatore; Arena, Fabio; Termine, Francesco; Canale, Antonino; Olayode, Isaac Oyeyemi; Neduzha, Larysa; Zuccalà, Yuri
    ENG: COVID pandemic has abruptly changed people habits and lifestyles worldwide, including the usage and perception towards all the different transportation systems; to this date (mid-2021), the pandemic has been going on for over a year now, and there is still no certainty about when it will end. A drastic decline in the number of commercial flights both national and international has happened, as a consequence of the lockdown policies adopted by the various countries around the globe in order to prevent the infection from spreading around, and with variable trends depending on the period and the reciprocal agreements between the various states. Land-side public transportation too has witnessed a backlash mainly due to similar policies or even not leaving home during lockdowns, often working remotely from home, and switching from public transportation to driving, walking or cycling if necessary. COVID-19 and transport are linked by a two-way relationship: if it is true that COVID-19 impacts on transport systems, it is also true that transport systems, in turn, have a very important role in the spread of the pandemic. Swabs first and vaccines recently, are raising new hopes about the pandemic ending soon. The consequences of COVID-19 will in any case be significant, and will revolutionize the way of conceiving transport, meaning new challenges for scientific research.

    Pollutant Emissions in Ports: A Comprehensive Review
    (MDPI, 2021) Barberi, Salvatore; Sambito, Mariacrocetta; Neduzha, Larysa O.; Severino, Alessandro
    EN: In recent decades, maritime transport demand has increased along with world population and global trades. This is associated with higher pollution levels, including the emissions of GHG and other polluting gases. Ports are important elements within maritime transport and contribute themselves to pollutant emissions. This paper aims to offer a comprehensive yet technical review of the latest related technologies, explaining and covering aspects that link ports with emissions, i.e., analyzing, monitoring, assessing, and mitigating emissions in ports. This has been achieved through a robust scientific analysis of very recent and significant research studies, to offer an up-to-date and reliable overview. Results show the correlation between emissions and port infrastructures, and demonstrate how proper interventions can help with reducing pollutant emissions and financial costs as well, in ports and for maritime transportation in general. Besides, this review also wishes to propose new ideas for future research: new future experimental studies might spin-off from it, and perhaps port Authorities might be inspired to experiment and implement dedicated technologies to improve their impact on environment and sustainability.

    The Role of Cold Ironing in Maritime Transport Emissions
    (AIP Conference Proceedings, 2022) Barberi, Salvatore; Campisi, Tiziana; Neduzha, Larysa
    ENG: Maritime Transport is one of the sources of atmospheric pollution, contributing with gaseous emissions mainly caused by marine engines and fossil fuel combustion, and characterized by the production of substances such as CO2, CO, NOx, SOx and PMx, harmful to the environment and human health. Cold Ironing, also known as Alternative Maritime Power (AMP) or Shoreside Supply, is one of the most relatively recent technologies designed to reduce emissions in the maritime industry: it consists in a three-parts system to connect shore-side located power sources, especially with renewable energies and smart grids, to on-board systems able to receive and store electricity, through intermediate connection devices that allow electricity to flow from the port into ships. This technology has been proved to bring financial and environmental benefits, considering also the rise in fuel costs; however, it is still facing some challenges in getting widespread worldwide, mainly due to retrofitting and upgrade costs. It will also require more specific policies and regulations involving stakeholders of different technical and geographical nature. Scientific research is however promising under all these aspects, as it is demonstrating significant reductions in terms of emissions and externalities.
