    Opis:
    Nowadays, a high-quality road network is necessary for sustainable transport systems. A sharp rise in automation results in increased transport problems. The most serious problems include the traffic infrastructure congestion, congestion, and increased risk of a traffic accident and, of course, a negative impact on the environment. The mobility of inhabitants and the transport of goods are one of the key transport objectives. A junction still constitutes the most critical point on the road network. That is why crossing the road smoothly and safely makes a large difference for the vehicle. This article provides an analysis of the current state of the selected circular junction. On the basis of the conducted survey, new solutions for this junction were presented, which should prevent the traffic conditions from becoming obtrusive. The Aimsun microsimulation was performed for checking the new proposals.

    Opis:
    This article focuses on traffic modeling of intersections in Aimsun. The intersections studied are in Bratislava, the capital of Slovakia. Every year, the number of vehicles on roads increases and congestions are created. Individual intersections do not have unlimited capacity. Simulations help to predict possible future problems and thus the possibility to prevent them. Accordingly, at intersections on Vajnorská street, a traffic survey was carried out using video cameras. Then, simulations were carried out in Aimsun. The results are shown in the tables separately for each intersection along with the determined overall quality level of the intersection. In addition to the current situation, simulations were carried out for increased traffic by 10% and 20%, and overall quality levels were also determined. Finally, the results were evaluated and compared with each other. This article points out the importance of research into the permeability of important points of the road network: intersections. It is necessary to carry out capacity assessments when planning any construction that will affect traffic in each location.

    Opis:
    The European Union has an ambition to achieve zero road deaths by 2050. It is an ambitious target, but not an unachievable one. The installation of a front brake light, which provides information to other road users that the vehicle is braking, can help to achieve this goal. Today, this information is available to road users who can see the rear of the vehicle. Because the brake lights are located at the rear of the vehicle. The information that the vehicle is braking is also important when looking at the front of the vehicle. Whether it is other drivers or other road users such as pedestrians and cyclists. The aim of this paper is to conduct a research among professional road transport drivers what their opinion is about the front brake light. From their opinion, we will conclude whether such light has the potential to improve road safety or not.

    Opis:
    Nowadays, the issue of sustainable mobility is very resonant in the professional public. Main topic for discussion is a transport as a one of the biggest polluters in the world. Today's transport brings a number of benefits to society, but often it has a high price. This price is paid by wasted human lives and serious environmental damage. Therefore there is no wonder that a number of cities, municipalities and regions regard transport as the key to their development, but at the same time as a threat to the health of the population, their safety and quality of a whole life. The combination of public and shared transport is necessary for clean and smart mobility. Shared economy is a concept of social change in the 21st century. This paper is focused on above mentioned issues. It describes levels of the smart city concept and principles and forms of shared economy in transport and shared mobility.

    Opis:
    Research background: In determining the prices in road transport, carriers usually use the calculations based on a so-called routes utilisation coefficient, which allows the carrier to also take the possibility of the return rides without load into account. Currently, it is usually used as a constant from the interval from zero to one. Purpose of the article: Considering a different offer of return transport from individual European Union (EU) countries, it can be assumed that the routes utilisation coefficient should have different values because there is a varying level of non-zero probability that the vehicle will return without a load. This study therefore proposes a new approach to determining the value of this coefficient based on transport direction. The study also aims to identify clusters of EU countries, for which the common value of the coefficient should be set. Methods: The Analysis of Variance (ANOVA) test was used to verify the assumption of the differences among the means of transport offers. Cluster analysis was used to identify the aforementioned groups of countries. This analysis is based on real data on transport offers to Slovakia from 18 different EU countries. Findings & value added: The results of the analysis can also be used in other EU countries because if significant differences in transport offers to Slovakia exist in individual countries, there is a reasonable assumption that this conclusion will also be valid in other countries. The analysis demonstrated that it is more appropriate to use the routes utilisation coefficient with various values, dependent on the transport direction. For the transport companies, implementation of the obtained results into practice is beneficial to increase their competitiveness through the more precise setting of transport prices, but also to the optimisation of the transport price itself with regard to the expected costs.

    Opis:
    In the Slovak republic, there is an increase of building roundabouts in both urban and non-build-up areas. The construction of roundabouts in urban areas brings mainly calming of traffic intensity. A roundabout in non-build-up areas could be built only within certain conditions. In this paper, we have been studying a small roundabout location and its traffic characteristics in the city of Hlohovec. In some cases, a small roundabout could be very good solution for exceeded traffic flow capacity of signal controlled intersections as well as for intersections with a high number of traffic incidents. But in our case, a small roundabout is not suitable for such intensity of vehicles as we measured in transport survey. So we focused on other possibilities how to improve this current situation. We have decided to make a proposal of signal controlled intersection as well as a turbo roundabout and compare the results of traffic characteristics of each proposal. We have made several simulations of each variant of traffic situation, using transport-planning software Aimsun, and calculate average values of all recorded traffic characteristics. As inputs, we have used intensities and other basic data obtained from transport survey. Using simulations outputs of transport planning software, we have been able to compare a current state with signal controlled intersection and turbo roundabout. Traffic characteristics of turbo roundabout show significant improvements compare to signal controlled intersection, f.e. in delay time (more than 68%), travel time (more than 22%), number of stops (more than 73%). Turbo roundabout seems to be the best solution for traffic organising at this chosen intersection in the city of Hlohovec, regarding travel time, delays, number of stops and safety at all.
