The work purpose consists in the analysis of the situation in passenger transportation of countryside and bus distribution on routes. The route investigation was carried out at different daytime by means of passenger number calculation and data recordings in the prepared tables during a day, a week, a month and also during the year, that is, using a calculating-table method. The analysis of bus operation on a route allowed drawing conclusions that this route may be favorable for investors and economically profitable. Besides, it is socially necessary for low-income population groups having no their transport vehicles. The investigation novelty consists in the adaptation of a calculating-table method to rural routes. Conclusions: modern automobile passenger transportation company is impossible without efficient passenger transportation management; one of the main components in passenger transportation management is passenger service improvement, which can be achieved only by empiric investigations of passenger flows on the routes; at the proper selection of vehicles the analyzed car route can be commercially profitable and long-term that is ensured by a quantitative analysis of vehicles and specification of bus schedule taking into account the need of population in travels.

The capability of dissipating supercooled fogs by aircraft seeding has been recognized since Schaefer experimented in 1946. Except for some localized application of this weather control and some side effects of research aimed at precipitation increase, no organized program of airport weather improvement was established in the United States until 1963. Seeding of supercooled fogs by dry ice was organized during two winters for the purpose of increasing airline schedule reliability at airports subjected to this cold fog. Better than 80% success was attained by this method, resulting in the operation of approximately 200 scheduled flights which would otherwise have been canceled. Typical examples of visibility improvement after less than an hour of seeding are illustrated. The direct benefits resulting from these programs outweigh the costs significantly and suggest that similar fog dispersal operations should be expanded to other areas of the United States which are subjected to supercooled fogs.
