摘要：AbstractThis paper addresses the problem of modelling and simulation of the vehicular traffic flow in a road network by adopting a measure-theoretic framework. This allows to describe the system from both, a microscopic and a macroscopic point-of-view simultaneously, in the sense that two scales co-exist and are coupled, namely a set of moving agents and an average density. The resulting mathematical model consists of a strongly coupled PDE-ODE system with non-local interactions. Within this work we specify this multiscale model for a single-lane roundabout, that is, an example of a road network. Then, we focus on the computational aspects in order to develop a setup for numerical simulations and to analyse the results of some experiments. This multiscale simulator can reproduce phenomena that characterize the real physical system, e.g. self-organization effects, and thus it can be adopted as an environment for control algorithms benchmarking or as a tool for simulation-based traffic flow control and optimization.
