The analysis of the existing international practices was carried out, which shows that in the leading megacities of the world, for example, New York, London, Beijing, Paris, Berlin, there is a state or regional legislation regulating the tariff setting when organizing transportation by taxi. In Moscow, there is no such regulation, and the existing level of tariffs, and accordingly, hourly revenues, do not allow, provided that the work and rest schedule is observed, to ensure the established average salary for drivers in the city. Moreover, the tariffs from the «aggregators» operating on the taxi market can be qualified as dangerous (causing risks of accidents). Keywords: cars, taxi transportation, aggregators, tariffs, methods, hourly revenues, safety, emergency risks, regulatory legislation, international experience in tariff setting.
