The International Conference on Urban Transport and the Environment have successfully been reconvened for 27 years, always attracting a wide international spread of delegates, well established as the premier event of its type. Meanwhile, the substantial growth of maritime shipping has resulted in large transported quantities around the world, creating a demand for innovative solutions for ports and fleets, well reflected by the success of the First International Conference on Maritime Transport, held in 2019. These two apparently parallel topics meet in the transport and environmental management of coastal cities, both being affected positively and negatively by landslide and seaside traffic. The continuing requirement for better urban transport systems and the need for a healthier environment creates a fertile environment for original ideas, innovative approaches and applications of advanced technologies, their tests and evaluations in practice. Moreover, there is a growing need for integration with IT systems and applications to improve safety and efficiency. Maritime Transport is highly interconnected with rail, road and air services, as well as inland waterways. Each of these must therefore operate complimentary of one another to maximise efficiency and respond rapidly to variable economic and political contingencies. The variety of topics covered by the conference reflects the complex interaction of the transport systems.
