Traditional ways of monitoring urban traffic data and managing the information are no longer valid, as the landscape is altered by cutting-edge technologies (computer vision and artificial intelligence), new societal values (environmental awareness) and changing urban mobility modes (self-driven vehicles, bicycles, etc.). Intelligent Transport Systems are key enablers to meet ever-growing citizens' needs in terms of mobility services and offer tailor-made measures to the new variety of urban mobility scenarios. Among them, the development of advanced Traffic Management Systems, such as UrbanDynamics, can significantly contribute to: (i) optimise the use of the existing infrastructures, (ii) foster a more extensive use of collective and sustainable transport modes, and (iii) integrate private vehicles in multimodal combinations. The compliance of these objectives is perfectly aligned to current Smart City challenges to achieve safer, cleaner and more competitive urban mobility.
