According to experts, passenger and goods transport is essential for the economic growth and prosperity of each society. Every transport system burdens the environment, using the dedicated infrastructure and its resources. The contemporary means of transport use the environment to generate propulsion energy (directly in combustion engines or indirectly in electric power plants). Rail transport is considered to be environment-friendly owing to its low external costs, which include the costs of the consequences of discharging gases and/or dusts into the atmosphere. In the paper the method of research, which is characterized by a different ratio than in the observation of the subject to the phenomenon under consideration. Observing the studied phenomenon has not been changed. The aim of this research was to identify the components of rail transport costs borne by the orderer of a transport service and by the electric power plant supplying the railway with electricity, on the basis of a case study of the transport of aggregate. Calculations showed the share of such costs in transport costs (in the considered case) to be marginal. In the light of this finding the definition of external costs is critically evaluated..

The transportation activities realization in transportation system needs taking into consideration its environmental aspects. The rules of the environmental management, which have been functioned in society consciousness, accept the beginning of actions for identification of main environmental risks in form of so-called: significant environmental aspects. The recon character of the study cause the identification of various environmental aspects of air transportation and a comprehensive analysis of noise emission of air units powered by combustion engine is presented.

Development of civilization takes place mainly in a natural way in industrial clusters. That agglomerative network consisting in tying urbanised areas can be transformed with time, through functional connections, into metropolitan centres [1], which should provide with the efficient transport infrastructure. At the stage of planning-urban concept from the scope of communicative solutions, assumptions are referred to combine aspects of functional, technical, economic, and environmental. The organised transport is an only perspective way of transferring in large urbanized areas. Currently the predominant form of transport people and goods in the country is an individual using circular transport vehicles.
