Dear Colleagues,

Transportation systems are beneficial to society, but they also account for serious challenges and various side-effects, e.g., accidents, injuries and fatalities, congestion, noise, air pollution, and petroleum dependence. In the context of the 2030 Agenda for Sustainable Development, harnessing the advancements in technology can bring improvements to the transportation system. These issues are at the forefront of the agenda of most policymakers. Recently, unprecedented changes in mobility patterns arose from the context of the COVID-19 pandemics, with consequent impacts on citizens' life. Although there was a slowdown in the economic activity and mobility during 2020 mostly due to the pandemic, resulting in a major drop in accidents, pollutant emissions, and mobility levels in general, the truth is that soon transportation activity will continue to increase to face society needs. Thus, evaluating and curbing traffic-related impacts is crucial for a better life, air, and health quality. There is the need of rethinking the transport system to effectively address numerous issues from transport efficiency and flexibility to climate change actions. In this field, intelligent transport systems can be valuable and the understanding derived from sensor and monitoring-based data can be remarkable, from getting insights into active travel and pedestrian movements to the development of more sustainable driving and traffic operations, that can therefore improve the sustainability of both passenger and freight transportation. In this Special Issue, we invite the submission of outstanding research papers that specifically focus on intelligent transportation, with a holistic perspective involving different viewpoints of the mobility agents, policymakers and car manufacturers, on emerging mobility services, safety and driving behaviour, environmental and air quality impacts, and anticipating traffic and environmental impacts of both conventional and automated and connected vehicles. The scope of this Special Issue is to cover state-of-the-art contributions under the form of original research and/or review papers with a general focus on intelligent transportation and on, but not limited to, the following topics:

• Transportation system preparation for extreme events;
• Traffic-related environmental and air quality impacts;
• Safety and security in all transportation modes;
• Intelligent transportation and smart cities;
• Freight innovative solutions;
• Smart cities transportation and land-use planning;
• Innovative sources of information in intelligent transportation systems;
• Driving behavior and operation assessment;
• Automated and connected vehicles;
• Future trends for smart mobility.
