In this paper a system analysis integrated approach to the pro-ecological urban traffic management and control problems is presented. In this context the optimal, in the sense of air pollution, traffic road control problems in the street canyons are formulated and solved. A general traffic control idea for the street canyons is proposed with emphasis placed on the development of advanced hydrodynamic control model of the street canyon including: multi-lane, 1-D bi-directional model of movement of several types of vehicles, of several emission types, and of emitted pollutants. The optimal in the sense of total travel time, pollutant emission and concentration pro-ecological control problems for an isolated street canyon and three integrated substitute street canyons representative for the city inner are formulated and illustrated by 12 numerical examples.
