One of the factors influencing the level of traffic noise is the type of vehicles moving on the roads. The paper presents comprehensive research, as conducted by the authors, which sought to assess the traffic noise level generated by different means of transport. A comparison is made between the noise generated by personal cars, a truck and different types of motorcycle. The maximum sound level and the equivalent sound level emitted by the investigated means of transport were analysed in the entire frequency band and in the individual 1/3 octave bands. Based on the research, conclusions have been formulated regarding the influence of the different types of means of transport and their speeds on traffic noise near a road, along with possible ways to reduce its level.

The value of aerodynamic drag is the largest, when a vehicle is moving with higher velocity. It seems that drag reduction is the most important step for reducing the fuel consumption of haulage trailer sets. Using aerodynamic trailer devices is one of many ways for reduction of fuel consumption. This paper deals with experimental measuring of the truck set model in a wind tunnel. The scale of the model was 1/24. Resultant values of the drag reduction for chosen aerodynamic devices are discussed at the end of the paper.

Wartość oporu aerodynamicznego jest największa gdy pojazd porusza się z większą prędkością. Wydaje się, że redukcja oporu jest najważniejszym krokiem do zmniejszenia zużycia paliwa zestawów transportowych zawierających naczepy. Zastosowanie wyposażenia aerodynamicznego naczep jest jednym z wielu sposobów na zmniejszenie zużycia paliwa. Niniejszy artykuł poświęcony jest eksperymentalnym pomiarom modelu zestawu ciągnika z naczepą w tunelu aerodynamicznym. Skala modelu wynosiła 1:24. Uzyskane wartości zmniejszenia oporu powietrza dla wybranych elementów wyposażenia aerodynamicznego omówiono w końcowej części pracy.

The purpose of this article is to present measures related to the load securing on European level. The road transport plays significant role in Europe. With the increasing volume of goods carried by road the number of vehicles are increasing and also the number of accidents involving trucks. The appropriate load securing increases the safety of road freight transport. European Best Practice Guidelines on Cargo Securing for Road Transport issued by European Commission are the first document on European level offering the load securing information. There is also a lack of load securing training for truck drivers in most of the EU member states. In most member states the load securing is not the part of the training to obtain truck driving licence. The directive 2003/59/EC on the initial qualification and periodic training of drivers of certain road vehicles for the carriage of goods or passengers shall improve the situation. The education of truck drivers from load securing began since September 2009. The standard EN 12195-1 offers calculation base to design load securing arrangements. There were cases when it has created unreasonable demands for load securing. The standard has been revised and finally published in May 2011. However, still the differences between the designs according to the EN 12195-1, methods using in Nordic countries, Germany and according to the IMO/ILO/UN ECE Guidelines on packing of cargo transport units exists. European Best Practice Guidelines on Cargo Securing for Road Transport are need to be revised to reflect the development in the area of load securing.
