Original abstract

In this study authors focus on traffic dynamics and its impact on the pollutants dispersion in two street canyons forming an intersection equipped with traffic lights. A model based on Eulerian-Lagrangian approach to moving objects has been developed and integrated into a commercial CFD code StarCD. Inclusion of traffic dynamic leads to a better description of dispersion processes of pollutants in an intersection, where peak values of pollutant concentrations are often located. Informations about traffic situation were obtained from in-situ measurement. Results of CFD predictions of NOx concentrations are compared with measurements acquired from an automatic monitoring station located in the intersection.
