How the Smart Underground Space could help meet urban transport challenges?, ITASC 2017


Published on

This keynote was presented at the International Symposium for Intelligent Transportation and Smart City (ITASC 2017; Shanghai). It presents first the urban transport challenges and how the underground space helps meet these challenges. Then it presents the application of the smart technology to establish an inclusive approach of the underground space; that is based on the collection and analysis of data throughout the lifecycle of the underground space. It shows that this approach enhances both the security and efficiency of the underground space.
