This study presents a model of continuous oncoming traffic flows of vehicles along highways. The flow of atmospheric air and impurity particles is modeled numerically based on unsteady Reynolds-Averaged Navier–Stokes equations using the MTFS® authoring software. Detailing of the flow patterns allows arbitrary length regions of periodicity, taking into account a crosswind. The examples provided demonstrate some of the results of the aerodynamic interaction of two oncoming columns of vehicles. The model of aerodynamic interaction of vehicles in traffic on a straight section of road in tunnels allows an arbitrary number of vehicles in each sub-region, along with an arbitrary, periodically repeating configuration of vegetation and buildings on the side of the road to be considered.
