Our research goal was to assess expected efficiency of «Clean air» Federal project with its activities aimed at reducing ambient air contamination and population health risks.We revealed that finding solutions to the project tasks on emissions reduction that had been set without taking into account peculiarities of city design, development, landscapes, meteorological conditions, and other factors, would not result in improved ambient air quality. Road and transport systems are to be modernized basing on transport flows modeling and application of calculations taking into account transport flows structure, speed, and intensity as well as some other parameters.
