Peter Faith *PASSENGER ROAD TRANSPORT TRENDS IN THESLOVAK REPUBLICThe article deals with the present trends in the passenger road transport in the Slovak Republic. It provides the characteristic of indicatorsof development phases of the passenger road transport trends. Existing increase of number of vehicles and individual road transport performancesshall bring unfavourable impacts on environment on the one hand and on the other hand, it shall be the source of the state budgetincome.Permanent conflict between individual road transport and mass passenger transport makes all administrative authorities to follow impactson the life of inhabitants in agglomerations with assumed higher concentration of inhabitants. Demand for passenger cars will be permanentand any decrease in the passenger road transport cannot be assumed. Therefore, it is necessary to show a permanent interest in this sphereof problems and deal with it on the highest possible level.1. IntroductionFollowing the Slovak Republic accession to the European structuresand gradual market economy development, markedly changeshave been accomplished including different social and populationimpacts.At present, passenger road transport trends in our country arenecessary to be studied in light of different aspects. On the onehand, existing increase of number of vehicles and individual roadtransport performances brings unfavourable impacts on environmentand on the other hand it represents an income to the statebudget from sale of fuels, vehicles and other items related to thepassenger road transport.A separate chapter includes building necessary transport areas,namely parking and lay-by areas, final building and maintaininggood conditions of all road categories.Most intensive passenger road transport development is evidentin areas with high density of population where it causes difficultiesin sustainable environment, i.e. it acts mainly as an unfavourablefactor.Permanent conflict between individual road transport and masspassenger transport makes all administrative bodies to followimpacts on the life of population in agglomerations with assumedhigher concentration of inhabitants. It is necessary to determinean effective co-operation rate between individual road transportand mass passenger transport which is impossible in number ofcases. Different measures, however, may be taken to influence efficientlymodal split, particularly in the event of travels for workpurposes, i. e. regularly repeated trips per day.All present impacts on passenger road transport developmentwhich included, for example, the energy crisis at the beginning ofseventies, the increase of fuel prices or cars didn’t cause anymarkedly deceleration of development of the said mode of passengertransport. This trend may be observed not only in the developedcountries where the degree of passenger road transport amounts toaround 2.5 inhabitants per one passenger car but also in lessdeveloped countries with the degree of passenger road transportamounting to around 5.5 inhabitants per one passenger car.2. Present passenger road transport trends in SlovakiaIssues concerning development and reach of reasonable saturationof individual transport needs of the population rank amongtopical issues, in particular, in relation to a living standard, the wayof living and environment. Relation to a passenger car and to thepassenger road transport trends in general represents an importantfactor. Opinions concerning passenger car have been different andreflect political and economic situation of the society.Slovakia during its independence period has failed to reachthe degree of passenger road transport of majority of Europeancountries and it even lacks behind the Visegrad Four Countries orsome Baltic Countries. At present, the degree of passenger roadtransport in Slovakia has amounted to about 4 inhabitants per onepassenger car which in the Czech Republic has amounted to 2.4inhabitants, in Hungary to 3.5 and in Poland to 3.1 inhabitantsper one passenger car [2].* Peter FaithDepartment of Road Transport, Faculty of Operation and Economic of Transport and Communications, University of Zilina, SlovakiaE-mail: Peter.Faith@fpedas.uniza.skCOMMUNICATIONS 3/2008 ●33
