The article deals with research on the relationship between the performance of road and rail freight transport and transport infrastructure in EU countries. The authors of the article examined the relationship between transport performance and transport infrastructure by correlation and regression analyses. Verification of the statistical significance of the regression model was also performed. The main objective of the contribution is to find out what are the relationships and influences between transport infrastructure and development of transport performance. Research has shown that the strength of the relationship between transport infrastructure and transport performance is different for states. There are strong dependencies as well as strong independent relationships between the transport infrastructure and transport performance.

Many large cities in Europe are currently trying to reduce the amount of harmful substances for the residents. Road transport is also an important source of air pollution. One way to reduce pollutant production is to operate more environmentally friendly vehicles. The paper analyses data obtained during practical tests of a hybrid vehicle in urban traffic. The individual components of the exhaust gases are calculated in g/km and they are compared with the values for conventional vehicle propulsion. The data was obtained through a commercially available exhaust gas analyzer and a calculated amount of emissions produced from available data from the engine control unit. The results shown that using of this type of propulsion has its importance in cities with increased air pollution. During urban operation, the hybrid-powered vehicle was powered by an electric engine up to 67.70% (75.40% of the time). As a result of operating such a vehicle in the city, emissions of CO2, HC and NOx are significantly lower.

In 1956, there was an important step in international road freight transport. The CMR Convention, the main purpose of which was to unify the rules for the international transport of goods and thereby promote the development of international trade, was concluded. From a practical point of view, this is of great importance to both carriers and transporters. Similarly, this Convention describes the most important document for the carriage of goods and that is the consignment note CMR. In recent times, the term neutralization has been used in conjunction with this document in transport. We want to clarify the importance of this word in transport. The aim is also to find out to what extent carriers have real experience with CMR neutralization and when transporting what kind of goods the most frequent neutralization of documents is used. The purpose of this contribution is to explain what the term neutralization in transport means, because there is no legal regulation or norm to define it. This term is used mainly in chemistry. Furthermore, we would like to verify the hypothesis that the neutralization of consignment note CMR is actually used in international road freight transport and whether neutralization is only used for a particular type of goods, such as electronics. To verify the hypotheses we conducted a survey at the carriers.
