Author: Milan Dedík, Matúš Dlugoš, Jozef Gašparík, Vladimír Ľupták, Peter Blaho
Abstract: This paper is focused on analysis of the empirical models of transport planning in railway transport. At first are described general information and basic principles about known models. In the second chapter are mentioned current empirical models used in railways transport. There are explained methods of calculations for Nyvig and Lill´s gravitational model at all and introduced comparison of optimal values with actual values at chosen transport routes according to Lill´s model. The third chapter includes proposal of the extension the current Lill´s model including the practical application at the concrete chosen transport route.

Abstract: The report focuses on assessing the advantages and disadvantages of night distribution in selected European cities. The first chapter is focused on projects focused on night distribution of goods in the city centre. The second chapter deals with a more detailed analyses of night distribution in some countries of the European Union. It shows concrete example, a solution for night distribution, which can be applied to our Slovak cities. Even in Slovakia, it has to deal with the issue in view of the constantly increase the number and the duration of traffic accidents not only in Bratislava, but also in all regional cities.
Title of article: Modelling traffic conditions in the cadaster of Veľká Lomnica
Author: Matúš Korfant, Ján Palúch, Marián Gogola, Rafał Jurecki
Abstract: This article is focused on the analysis of the current traffic situation in the cadaster of Veľká Lomnica and suggestions for its improvement. The most important intersection of the road I/67 and II/540 is problematic where is also located the railway crossing with a light signalling device. As a basis for the traffic analysis was performed traffic survey at the four positions in the cadastral territory. Its analysis provides information about the current traffic intensity and is also the basis for the simulation of traffic in traffic -
Title of article: The impact of University of Žilina´s employees on regional development
Author: Lucia Možuchová, Lucia Gašperová, Mária Rostášová, Dorota Jelonek
Abstract: The university is an important part of the region's infrastructure and has the potential to initiate changes and transform the economy into a diverse range. The presence of a university in a host city or region has a strong impact on regional development. Universities are usually among the largest employers in the city. Their employees, students and visitors spend some of their finances in this city, which have an impact on local and regional economic development. The total size of the impact of university varies depending on the size of the university and the characteristics of the local and regional economy. The primary aim of the contribution is identification of the selected short-
Title of article: Driver salary identification by hypothesis testing
Author: Miloš Poliak, Patrícia Šimurková, Adela Poliaková, Marek Jaśkiewicz
Abstract: This paper outlines comparing two independent samples, particularly average driver salary in Slovakia and the other EU countries. Significant differences between salaries are pointed out through two examples dealing with hypothesis testing. For Western European Union countries, the level of salaries in road transport is higher in absolute terms compared to the salaries of drivers in the central and eastern parts of the European Union. Different salaries and requirements of wage regulations create a discriminatory environment among entrepreneurs however harmonization of salaries in the field of road transport is specific because carriers offer transport throughout the whole European Union market.
Title of article: The impact of roof box on fuel consumption
Author: František Synák, Vladimír Rievaj
Abstract: Passenger vehicles are major petroleum consumers and contributors of greenhouse gas and criteria pollutant emissions in many countries around the world. The amount of fuel consumed affects the environment, status of health of human population as well as financial costs that are associated with vehicle operation. The roof box is one of the often used vehicle attachments. The aim of the paper is to measure the increase of fuel consumption affected by an installed roof box. The impact of roof box on the increase of fuel consumption is measured at the speeds of 50 km.h-
