The paper deals with the possibility of energy consumption reduction in train traction. The mathematical model of train traction calculation is furnished and accommodated for purposes of definition of optimum journeys by the criterion of least energy consumption in given peripheral conditions i.e. within specified operation time and at highest allowed operation speeds. Based upon the model worked out the calculations have been completed on the example of one route section and different types, trains and train masses. The values of absolute and relative deviations in energy consumption have been obtained for different modes of operation and the most favorable methods of operation from the point of energy consumption have been established. In order to have certain optimum aspects of operation carried out in practice the paper puts forward suggestions for the elaboration and form of instructions for the operator. These instructions should for reasons of simplicity and easy reference contain graphical symbols and necessary operation information. It has been suggested to name the manual 'Operator's Information' while it would serve as recommended operation method to the driver. The paper lists all variants and forms of issuance of the proposed operator's information.

Over the last four years in the Republic of Croatia changes have taken place also in the segment of motorists training and licensing in an atmosphere of significant social, political and economic changes and wartime conditions. Regulations have undergone change in this segment insomuch that it has been structured on a marketing basis, training has been separated from licensing examinations, while the number of Driving Schools has tippled, and the segment has been given the required competitive atmosphere. From the aspect of training/licensing programs and management the segment has almost reached the level of same aspects in individual European countries. It is necessary to pass as soon as possible respective regulations for this segment coordinated with the new Road Traffic Safety Act and to structure the segment of motorists training and licensing in conformance with these regulations.

The paper deals with the quantities analysis of available data on the up-to-date trend of selected capacities of the telephone network for the Republic of Croatia. Based upon the developments in the preceding period (1973-1990) it has been shown that it is possible to complete the planning of the long-term demand for the main telephone lines, i.e. the incidence of MTLs/1 00 inhabitants by means of a logistic model application.

The Croatian Railways as a member of the International Railway Union (UIC) and an integral part of the European railway system of lines have both the right and obligation of taking part in the unified traffic policy of Europe with the ambition of all European nations drawing benefits from the prudently managed railway system through optimum solutions in order to enable each transport aspect, the railways in particular, the manifestation of its advantages. International operations of the railways become increasingly important with the growth of the internal European market. Considering the fact that the forthcoming period brings the promise of favourable time for a vigorous development of the railways, the Croatian Railways as a member of the UIC are faced with major assignments on the program of accommodation to the requirements of the EC, i.e. the European transport system. The Croatian Railways must also establish and evaluate the priorities of activities from engineering, technological, management and commercial aspect. These should be fully coordinated with the European ones with adequate application of information science i.e. computerization, and all other modern technologies. The execution of schedules should be impeccable, strictly eliminating all delays. Train operation speeds should be increased in freight transport with maximum introduction of unit trains.

The paper deals with a review of efficiency of ultra short- term and short-term weather forecasts designed for motor traffic. On the pattern of local forecasts for the region of the City of Zagreb in the winter season of 1992/1993 the authors perform the assessment of accuracy of predicted precipitation in general, snow, snowfall and new snow layer of 5 cm and more, glaze, and minimum and maximum air temperature. The assessment of weather conditions has been completed by method of alternation while the assessment of air temperature has been completed by statistic methods congruent with physical scale values. General efficiency of prediction of all mentioned weather aspects has been satisfactory, despite the fact that forecasts are still being made by subjective methods. More successful have been the forecasts referring to the absence of a phenomenon important for motor traffic than those referring to its presence. This comes as a result of the subjective element in provision of forecasts. Forecasters have consciously over-emphasized the possibility of presence of some adverse weather condition in order to avoid joint responsibility for consequences at the time of its occurrence without being predicted or announced. Nevertheless, forecasts have proven to be useful for more efficient and more economic operations of The Winter Road Service in the metropolitan area of Zagreb.

The paper deals with the results obtained from a survey of traffic-and-handicapped-persons relationship mounted in Zagreb in the spring of 1991. The poll involved 305 examinees - respondents with different degree for handicap and other features whose impact on the answers provided by the respondents was of particular interest to the examiners. The responses given refer us to the disappointment expressed about the attitude of the community towards handicapped persons and the existing level of accommodation of solutions in traffic to the needs of handicapped persons, and the controversial issue of access and availability of public transit/facilities. The respondents have also provided objections and suggestions for the resolution of their problems. A crucial role in the process of forming of attitudes and their articulation refers to the way of living and aspect of handicap.

The paper deals with the system of basic and specific body motor capacities with reference to rescue at sea by using the canon relation. The survey has been completed on the sample by using a set of variables and a series of tests of basic and specific body motor capacities and elements of rescue. The patter of variable intercorrelation has been analyzed. A relatively high degree of correlation of motor capacities and elements of rescue comes as a result of impacts of repetitive and explosive strength, speed of coordination, and ability of completing motor capacity related tasks.

Road infrastructure as an indispensable part of the community and economic life has a significant place in the area of a coordinated development of the process of simple and extended reproduction. This means that distortions in the segment of conceiving one consistent road infrastructure financing system procreate a variety of negative implications reflecting on the subsystem of road and overall economic system Thus the facilities of road infrastructure become an element of destabilization of the road system functioning as a subsystem of the economic life in Croatia maintaining with it a dynamic interactive relationship in the process of operation. The paper deals with the distortion of the financing system and the inevitability of its transformation within the scope of the restructuring of the Croatian economy. The basic prerequisite of the process of transformation rests in the rational functioning of the investment activity which should be complex, comprehensive and consistent, without any anemic, undeceive and declarative quality.
