A field deterministic model of the vehicular dynamics in a generic urban street canyon with two neighboring canyons is considered. The assumed hydrodynamical model of vehicular movement is coupled to the gasdynamical model of the air and emitted pollutants. The vehicles are assumed to move on distinct left lanes and right ones. At the upstream and downstream ends there are coordinated traffic lights which introduce control parameters to the field model. The model of optimal control of street canyon dynamics is based on the two optimal multi-criteria control problems. The problems consist of minimization of the dimensionless functionals of the cumulative total travel time, global emissions of pollutants, and global concentrations of pollutants, both in the studied street canyon, as well as together with the two nearest neighbor substitute canyons, respectively.
