This paper deals with the issues of road, railway, river and postal traffic in East Croatia. Its Introduction section makes a review of the pre-war condition of traffic infrastructure facilities in the national region of East Croatia, as making part of the European integration processes, while being at the same time significant for the Republic of Croatia in the service of development of the entire national region. The paper further discusses damages from wartime devastation and their adverse impacts as felt in discrupture of traffic flows. The author elaborates and gives recommendations on the course of actions on the reconstruction as needed for prompt operation of the traffic system, in conjunction with the programs of construction and development of traffic infrastructure facilities in the post-war period.

Market makes an indispensable element of the development of democratic states. In the EC the internal transport market has already been structured, however there are a variety of unresolved issued. The economies of the nations of Central and East Europe must necessarily undergo restructuring, within the scope of European integration processes which then particularly refers to traffic. This makes an absolute prerequisite for a more comprehensive arrangement of relationships with the EC and its member states in this segment.

This paper gives recommendations for the application of Pegasus numerical algorithm for establishing the parameters needed for the computation of average vehicle speeds on two- way roads. The tables made by worked out by means of this method enable the substitution of incorrect diagrams that have been used up to this point of time.

Exceptionally high incidence of road traffic accidents with casualties and fatalities as related to the actual traffic volumes occur during the night. However only some 25% of traffic (viewed on the average) happens in the night - time period. The paper deals with an analysis of a variety of available data on traffic accidents and their consequences (with particular reference to the metropolitan area of Zagreb) which serve the author to draw uncountable evidence that the hazards of nighttime driving surpass (excell) the hazards of daytime driving. Furthermore nighttime road traffic accidents are by their consequences of more severe nature than the daytime, while high-quality road lighting substantially reduces both the incidence of accidents and their adverse consequences.

Road infrastructure as an inseparable element of community life and economy takes major position in a harmonized development of the process of simple reproduction and extended reproduction. This means that distortions in the segment of conceiving one consistent road infrastructure financing system yield a variety of negative implications reflecting themselves upon the road traffic subsystem and overall economic system. In this the facilities of road infrastructure develop into an element of destabilization of normal traffic system functioning being itself a subsystem of the economic system of Croatia keeping with it a dynamic interaction in the process of operation. This paper deals with respective distortions in the financing system and the necessity of its transformation within the scope of restructuring the Croatian economy. A basic prerequisite of the restructuring process rests in rational functioning of the investment activity which should be complex, comprehensive, and consistent without even minimum traces of being anemic, wavering or declarative
