  A general proecological urban road traffic control idea for the street canyon
is proposed with emphasis placed on development of advanced continuum field
gasdynamical (hydrodynamical) control model of the street canyon. The continuum
field model of optimal control of street canyon is studied. The mathematical
physics' approach (Eulerian approach) to vehicular movement, to pollutants'
emission, and to pollutants' dynamics is used. The rigorous mathematical model
is presented, using gasdynamical (hydrodynamical) theory for both air
constituents and vehicles, including many types of vehicles and many types of
pollutant (exhaust gases) emitted from vehicles. The six optimal control
problems are formulated.
