The continuity of activity field during the crisis situations is a way, how to reduce activities which is harmless for the transport. The goal is ensure minimal demanded level of services performed in the transport branch. This minimal level for performing the transport services are necessary for train operating.

The article deals with the problem of electric power production in terms of environmental impact, in particular the energy efficiency of its production to utilize primary sources. The efficiency of its production directly depends on the composition of primary sources and technologies used. Difference in efficiency by converting various forms of energy into electrical power and their ratio in the use directly affect the resulting efficiency, production of emissions and thus the environmental impact. Electric traction, its production, is burdened less efficient than other types of tractions used in transport, but at the final reconciliation of their consumption in vehicles, this difference decreases or delays because the vehicles themselves work with different conversion efficiency of its traction on mechanical work, vehicle driving.

Users in transport, forwarding and logistics companies use the mobile technologies for connect to existing information systems. By solving the ERIC Mobile project, these services will also be available on mobile devices. The article is aimed at lancing the requirements of all types of customers for the ERIC Mobile app. After the basic characteristics of the mobile device, the operation systems, the application development typology, the authors focus on the developing application “ERIC Mobile”. The aim of the article is to provide relevant requirements for further research and development of the software application of the rail freight information centre in Europe for end users of mobile devices such as smartphones and tablets.

Transport is one of the human activities that increases the amount of greenhouse gases in the air. CO₂ is the main cause of global warming and contribute for around 80 % of all greenhouse gas emissions. The paper presents CO₂ production based on the amount of sold fuel in Slovakia and Slovenia. Based on the obtained data, the calculations about the production of CO₂ according to the type of fuel was made. The conducted research has focused on the issue of traffic congestion and to reduce CO₂ emissions by 15 % in total by 2030, as Slovakia and Slovenia concluded an agreement with other EU members in 2009. External costs calculation was made with average price of 1 tonne emission credit in 2016 and with presumed average price in 2019. The case study takes into account the consumption of the gasoline and diesel in transport throughout all Slovakia and in Slovenia.
