报告内容简介:The dynamic part of the urban system, consisting of various types of transportation modes and commuters interacting in highly non-trivial ways, is a typical many-body system with both complex and universal behaviours. In this talk, I will present a few approaches in analysing and understanding such complex systems from quantitative, physical points of view, focusing on both the microscopic aspects and emergent phenomena arising from non-linear interactions between different components. In the first example, I discuss about the spatiotemporal dynamics of the traffic flow and the emergence of traffic congestions. In the second example, I discuss about traffic flow management near road intersections in a decentralised way without the use of traffic lights. For the third example I discuss about the dynamics of the taxi systems with and without ride-sharing. I will introduce some concepts about non-equilibrium phases in driven many-body systems, as well as various techniques including modern machine learning and artificial intelligence for the optimisation and efficient management of the urban transportation system.
