Because of the low living standard of the population motor vehicles are not renewed in time. Practically, new cars are not acquired; vehicles that have been operated for a long time are still exploited. The situation with exported transport vehicles is similar: they are obsolete and depreciated. Therefore, the degree of the exhaust standard excess is high and no toughening can achieve its considerable reduction. The fact that there is no prohibition to realize ethylated fuel excluded the possibility of using modern means of exhaust neutralization.

            Motor transport is exploited very intensely. There are no strongly expressed peaks in the density of traffic flow along the main thoroughfares of Bishkek. In fact the intensity is constant from 8:00 to 20:00.
