Piggy back technology of freight rail transport has particularly been invigorated .by the second world energy crisis of 1978. For purposes of relieving individual road routes, better utilization of rail infrastructure, reasons of environmental protection, lower costs, higher speed and safety of transport, the EEC supports financially the development of this aspect of transport technology. This paper deals with the existing organization/management of piggy-back transport in Europe with particular reference to the indices of efficiency of the German Society for Transport of Road Vehicles by Rail entitled 'Kombiverkehr A. G.'. Through identification of the forwarding agent as the organizer of shipment and delivery of goods by this technology the author refers us to the indispensability of this legal entity which as an entrepreneur acts on behalf of the business organization on completion of transport to satisfaction of the party providing and the party using this type of transport service.

This paper deals with a major function of the road in populated areas with particular reference to the measures taken on abatement of traffic flows. Considering the fact that major part of the area designed for traffic in populated areas has been used for purposes of road traffic to disadvantage of pedestrians and cyclists, it is necessary to initiate activities on purposes of structuring of the road area and this by measures of abatement of traffic flows with the basic objective of humanization of traffic i.e. harmonization of community life and traffic in the urban area. This paper deals with some examples of listed measures with low, r:cdiwn and high funding requirements.

Traffic infrastructure makes an integral part of the traffic and economic system of a country. This fact sets for those who create the policy of investment into the facilities of traffic infrastructure the task to have it based upon scientific nations and a coordinated activity of all segments of economy. This paper deals with the impacts of investment activities in the area of traffic infrastructure upon a congruent development of the economic system. The accent has been placed upon respective investment activity whose decisions are based upon economy-aspected criteria i.e. upon a more expressed import of scientific methods and application of scientifically determined and verified methods for this type of investment activity.

This paper deals with calibration (structuring) of a stochastic disaggregate binary model of road use selection: the motorway of a parallel road option. The variables of the model are the length of the road used and differences in the time of journey on the motorway and parallel road. Considering the road user/Es manner of assessment of time savings, a time variable has been structured in two ways: in the shape of 'differences' (time of journey on the motorway- time of journey on the parallel road) i. e. the quotient (time of journey on the motorway /time of journey on the parallel road).

Traffic signs refer to a specific technique of controlling some human relations, conditions and behavior in traffic. In other spheres of community life, as to a degree in traffic, these relationships, conditions and behavior patterns are being regulated by legal rules (standards) being communicated descriptively. Therefore it is important to define the legal nature of traffic signs, their impacts as referring to the obligations and liabilities, as well as the differences and specific aspects with reference to traditional conventional legal rules and standards.

The development of the automobile industry has invigorated the development and advancement of the tire manufacturers. Considering the fact that the tire is a major factor of traffic safety it should be secured proper maintenance and inspection.

New transport technologies can be grouped with reference to their engineering and technological characteristics into different systems, sub-systems and segments. However, in this process of grouping i.e. defining the modalities and terms it is indispensable to reach a unique standardized definition in domestic and international relations in order to avoid diverse terms for one and the same sub-system. Thus in practice we meet different terms for new transport technologies: integrated transport, combined transport, means of modern transport technologies, integrated transport systems, new transport technologies, etc. Up to this point in time only multi-modal transport (MT) has been defined from engineering/technological, management and legal aspects by acceptance of the Convention on Multi-modal transport on the part of the United Nations (UN), UNCTAD, in the year 1980. As other modern transport systems have not been defined so far or standardized on the model of the MT the author in this paper advocates a uniform and unique name of Integrated Transport Systems for the following three basic systems: Integrated Transport, Multi-modal Transport, Combined Transport, while each and every of them keeps its sub-systems and segments as presented in Figure l . The definition has been dealt with through synthesis and analysis considering engineering and technological characteristics, their compatibility, incompatibility and other relevant factors.
