In recent time, as the Chinese consumption level increases, the consumption quantity of high-value fruits, vegetables and seafood products have been increasing year by year. As a consequence, the traffic volume of refrigerated products also increases yearly and the popularization degree of the cold-chain transportation enhances. A low-temperature environment should be guaranteed during transportation, thus there is about 40% of diesel oil should be consumed by the refrigerating system and the cold-chain transportation becomes very costly. This study aimed to explore methods that could reduce the cost of transport packages of refrigerated products. On the basis of the heat transfer theory and the fluid mechanics theory, the heat exchanging process of corrugated cases during the operation of refrigerating system was analyzed, the heat transfer process of corrugated cases and refrigerator van was theoretically analyzed and the heat balance equation of corrugated cases was constructed.

W pracy przedstawiono wymagania jakim ma obowiązek sprostać kierowca i logistyk który zajmuje się transportem towarów. Do optymalnego wykorzystania czasu pracy kierowcy niezbędna jest właściwa logistyka przewozów. Aby procesy logistyczne przebiegały poprawnie niezbędna jest także wiedza spedytora o czasie pracy kierowców oraz o średnich prędkościach transportowych pojazdów ciężarowych. Ponadto spedytor musi doskonale się orientować w jaki sposób dokonywane są czynności przeładunkowe aby odpowiednio oszacować czas potrzebny na dostarczenie towarów.

The paper presents some requirements which have to be met by the driver and logistics manager responsible for the transport of goods. For the optimal utilization of the driver's working time it is necessary to have proper logistics of trucking. So as to have those logistics processes run smoothly, the forwarder must have knowledge about the driver's working time and about average transport speeds of the trucks used. Moreover, forwarder must be fully aware of freight handling procedures so as to properly estimate the time needed for the cargo delivery.

Increasing urbanization, lifestyle changes, decentralization of business activity and growing use of private vehicles (in conjunction with the failure of public transport) raises a number of negative phenomena, particularly in the urban areas. One of the most promising fields which seem to prevent this disasters is the introduction of underground freight transport, allowing the transport of goods (both to the city and from the city) by a system of tunnels and pipelines. The author browses solutions for underground urban transport, both implemented and planned. The article includes R & D centers engaged in the development of underground transport technology. Based on literature review and analysis the author assesses the prospects for the development of underground freight transport with particular emphasis on urban areas.
