Online Fast and accurate simulation of the emission and dispersion of traffic emitted pollutants is an important challenge of many European cities. Such a simulation is a tool for cities in supporting environmental decisions, and optimizing vehicular traffic in cities subject to constraints on pollution levels.
In this presentation a digital twin of urban air pollution with applications of traffic control is provided. Data from traffic air pollutant sensors, Copernicus services, and ECMWF forecasts are continuously coupled in an automated way to HPC simulations, which result in re-analysis and forecast for the urban traffic control. Establishment of the online simulation, the crucial point of digital twins will be aslo detailed.
The digital twin has been analysed in the TCI use case analysis process. The presentation will show the contributions by different platforms as well and the status of the joint white paper.
