In 2011, it was decided that the carrying public transport system in Bratislava would be tram transport. Today's transport system is based on radials, it was created as part of Bratislava's first comprehensive transport concept in the ?70s. One of the disadvantages of Bratislava's public transport system is the few tram lines in the city centre, which, with a large number of radials, causes vehicles from different radials to cluster together at dense and poorly spaced intervals. The disadvantage of the radial syst...

Climate change is a global problem with serious social, economic and distributional effects on the environment. It is one of the main current challenges for humanity. Changing climate conditions in the long term, as well as short-term fluctuations and non-standard variation of temperature characteristics, have a significant impact on the behavior of pavement structure. Since the end of the 19th century, average temperatures have risen to 0.6 -C. The article describes the results of measurements and evaluations of ...

Several types of transport integrates transit nodes. Transit nodes are located in built-up areas, inside cities or on the outskirts of cities, urban agglomerations. Transit nodes are an important part of public passenger transport. The article is about transit nodes on the regional railway line between Bratislava and Dunajska Streda. The transit nodes are the railway stations on this line. Intercepting parking lots are part of the transit nodes outside large cities. It is important to compare travel times from sou...

In addition to the traffic load, the temperature also has a significant effect on the course of stresses in cement concrete slabs. It is the load of temperature changes that is often underestimated. Recently, there have been significant changes in climatic conditions and increasingly frequent extremes (especially high temperatures in the summer months and extreme fluctuations during the day), which affect the behavior of road structures and the basic characteristics affecting the stress of cement concrete pavement...

Cement concrete pavements are very specific group of the road construction due to the different traffic loads and vary time difficulties in the course of maintenance and repairs. For the design of the planed repairs the increased requirements are imposed especially in the terms of repair life time cycle. The economical evaluation shall consider not only the value of the repair itself but also the cost connected with the diversion of air traffic during the execution of the maintenance and repairs. Therefore, is hig...

Environmental risk factors for environmental problems with physical, chemical and biological factors that cause or may cause health disorders as well as environmental degradation. One possible factor is noise. The World Health Organization (WHO) estimates that a target of 40% of the EU population is exposed to traffic noise of more than 55 dB and that more than 30% is exposed to levels of more than 55 dB at night. The issue of protection of the health of the population against the adverse effects of noise and vibr...

Recycling of asphalt is an important technological process applied worldwide. The strategy is to use as much milled, ripped or broke asphalt material into the new mixture. With the correct technological design, the maximum appreciation of this material is achieved. Due to the dominant use of asphalt mixtures in pavements, it is important to address the possibilities of their recycling. At present, a sufficient amount of reclaimed asphalt with good potential for further use is available in Slovakia. The problem is ...

The influence of the quality of life of urbanized areas in Slovakia is directly dependent on the development of transport. Both sites transport - transport infrastructure and transport services - are not only assessed in terms of the levels of traffic volumes or traffic flows on the urban road network. Recently, mobility and accessibility have been at the forefront as the main quality service of land use. On the other side, there is no uniform principle of their parameterization to determine the procedure for asse...

According to the sustainable mobility, there are many rules how to do best a moving the citizens in our cities. What is interesting that we do not have a classical ? technical rules how to reach the sustainability in transport. The big deal is coming from the NGO people, mainly. The politicians have open their arms for them and then defectively requires from professionals non-systematic solutions. In Bratislava, Capital of Slovakia, is like in other cities in Europe a huge development boom. Completely new down tow...

In Bratislava, Capital of Slovakia, there is a huge development boom on the edge of the Old City, where is risen up a new complex down town of the city. The territory specified on the edge of the first ring called Chalupkova Centre will have around 20 high-rises with different function and there will be more than 20,000 parking spaces. At present, the operation of the territory is at the border of the saturation flows. There will be a new bus station and begins to reflect on the new tram routes. The extensive trav...

There are many technologies in road construction to ensure the better parameters of materials, mainly strength and deformation parameters and in recent years are very interesting and necessary so called environmentally acceptable technologies. With the development in the field of asphalt pavements there are various types of organic or chemical additives applied. The main reason of this application is to reduce the temperature used for producing and especially for laying of asphalt mixture. Chemical additives are s...
