The Applicability of 3D Model in Calculation of Road Traffic Noise Level

This paper describes the procedure of drafting 3D model of calculation of road traffic noise level on the basis of the data obtained by means of the detailed geodetic records of the existing situation made exactly for that purpose, as well as 3D model obtained on the basis of the existing digital maps and ortophoto records of the observed area with the data collected by the tour of the grounds. The paper presents the comparison of the results of these models and the results of field measurements on the example of Čavle settlement, situated on the section of Rijeka-Zagreb highway, as well as the commentary on the applicability of the described models in calculating road traffic noise levels.
