“…4 and 5. The Figures present the results of measurements of the maximum sound level LAFmax, and of the equivalent sound level LAeq, recorded in the entire frequency band at different car speeds [7]. The recorded values of the maximum sound level strongly depend on the car speed; on the cement concrete surface they reach values from 74.4 dB at a car speed of 52 kmh -1 , through 79.5 dB at 75 kmh -1 , up to 84.8 dB at 98 kmh -1 .…”

Abstract. The article aims to measure the intensity of the exterior noise of a vehicle in motion. It provides the results of the measurements of the external noise of selected vehicles in motion and the impact of selected factors on the sound level of driving. There are done two measurements in the paper. Results from the first one are comparing noise level of 9 passenger cars according to the Directive 71/157/EEC. The second one shows the road surface influence on the exterior noise of moving vehicle where the sound level was measured by a road whose surface was made of slightly degraded concrete, and at a different place of the same road, where the surface was renovated by applying asphalt mix onto it.

“…As also mentioned in the text above, disadvantage of vehicles with a combustion engine is that they produce pollutants in populated regions. However, their harmful effects can be eliminated by creating low-emission zones, by prohibiting heavy goods vehicles to enter densely populated areas and their further partial replacement with electric cars [28]. Electric cars are also producers of harmful emissions, even indirectly.…”

Road transport is showing growth in the period of globalization. Its task is to transport cargo as well as people to the required location within the shortest possible time and at the lowest price. Thus, road transport plays a crucial role in enabling the globalization to be developed and improved. However, the internal combustion engine hat prevail among the vehicles of freight and passenger transport are the producers of gaseous emissions from the exhaust gases. Many developed countries of the world has committed themselves, inter alia also trough the Paris Agreement, to reduce global warming, and thus to reduce the production of harmful gaseous emissions. The result is the endeavour to replace the internal combustion engine vehicles that burn carbon fuels with the vehicles powered by electric motors consuming electric energy. The reason of such trying claims that road transport using the internal combustion engine vehicles is environmentally aggressive, and the problem would not be solved by implementation of the vehicles with electric motors. Such claim is based on the fact that an electric car does not produce any of primary emissions. From an overall perspective, it is also necessary to take into account secondary emissions that are produced during the electric energy production by which is the vehicle with electric motor powered. The purpose of this article is to assume the possibility of reducing global pollution by replacing the internal combustion engine vehicles with the vehicles powered by electric motors in dependence with producing the emissions during the production of electric energy.

“…It should also be noted that there is a disproportion between the existing toll system, which is valid only on certain designated networks of roads in the Czech Republic, and the fee for the use of the railway route for railway transport, where the whole railway network of the is charged. High accident rate of road transport is another negative factor in goods transportation on the road [13][14][15][16][17].…”

The article deals with the transfer of freight from road freight to railway freight transport. In railway transport, individual wagons or groups of wagons with a maximum number of five are used. Combined transport is used for commodity flows. Goods are loaded in ISO 1 containers with an outer length of 20 or 40 feet. Special ramps allow goods to be transported from the ramp to the container and vice versa. The system can be used for storage device, distribution and logistics centres with railway connections to public railway transport.
