THE DEMOGRAPHIC The world’s population continues to grow, and the appeal of megacities is confirmed, from Riyadh to Hanoi to Hyderabad. Today, the world’s most populous cities – Shanghai, Tokyo and Delhi – are home to over 35 million people. The need for connections between car-free city centres7 M and the suburbs, more densely populated and further away from urban people in Riyadh centres, is stimulating demand for mass transport. The increasing number of options available (train, tram, metro, bus, bike) for making a given journey means that rail needs to be integrated into seamlessmultimodal journeys. Tomorrow, the explosion in e-commerce will8.5 M people in Hanoi mean orchestrating the flow of people and goods to share urban space efficiently and viably. 11.3 M people in Hyderabad TECHNOLOGIES With generative design to optimise the use of materials and energy, connected rail infrastructure, and data-driven predictive maintenance, artificial intelligence is revolutionising the transport sector across all modes and services, while guaranteeing user safety. New transport system planning tools incorporate demographic trends and project population movements over the short, medium and long-term. Data is the keystone of this new-generation mobility. The unfailing 175 ZB protection of this data is a major challenge for these emerging the estimated technologies. To move towards the operation of more efficient and global datasphere sustainable smart infrastructure, tools such as BIM, simulation software in 2025 compared and applications, modelling, real-time control and the digital twin with 33 zettabytes in 2018 are essential when creating transport solutions and infrastructure. | 14
