Sažetak
Although it is not a member of European Union, The Republic of Croatia has brought the regulation regarding the noise protection which has been harmonized with The European Directive 2002/49/EC. Technical committee within the Croatian Normization Institute has acquired more than a hundred European norms from this area. In spite of that the noise protection in urban regions of Croatia is carried out sporadically. Only in those areas along roads where the noise levels are extremely high and the objections of local residents directed to town authorities are frequently repeated for years. The situation is completely different in case of excessive noise levels of the inhabited areas along highways. Stock companies which manage highways follow the orientation of the Republic of Croatia to take special care of the environment, and, thus, of the noise protection. Approximately 10 years ago intensive road construction started in Croatia and so far 1062 kilometres of highways have been built. The solutions for the noise protection that have been planned in the project documentation, mostly walls, have been carried out. In this paper the procedure of predicting the noise level in the environment in the process of making project documentation has been described for the section of the highway Karlovac-Novigrad. The real situation in the environment regarding the noise caused by traffic was determined by field measurements five years after the section in question had been opened to traffic. The prediction of noise protection on the project level has been commented upon with regard to the present noise condition when the highway is in circulation. It has been pointed out that that the noise protection by walls is only one very important, but not sufficient measure, and that overall solution requires permanent monitoring, establishing the system of condition monitoring, analysis of effectiveness and the possibility of application of other primary and secondary protection measures.
