Abstract

U ovom je radu na realnom primjeru urbane gradske cestovne prometnice prikazana ocjena učinkovitosti različitih mjera za smanjenja razina buke od cestovnog prometa. Za proračun razina buke odabrana je Masarykova ulica u gradu Zagrebu. Mjere koje su razmatrane su: prenamjena dijela ili cijele ulice u pješačku zonu, omogućavanje slobodnog prometnog toka noću, preusmjeravanje određenog postotka prometa u sporedne ulice te uvođenje zone „30 km/h“ – zajedničko korištenje kolnika za bicikliste i motorna vozila s ograničenjem brzine motornih vozila na 30 km/h. Proračun razina buke proveden je specijaliziranim računalnim programom LimA. Rezultati proračuna za određenu mjeru uspoređivani su s postojećim stanjem bučnosti. Kao najučinkovitija mjera za smanjenje razina buke pokazala se mjera prenamjene ulice u pješačku zonu. Mjera preusmjeravanja prometa pokazala je pozitivne rezultate smanjenja razina buke. Mjere omogućavanja slobodnog prometnog toka noću i uvođenje zone „30 km/h“ nisu pokazale pozitivne rezultate smanjenja razina buke od cestovnog prometa.

Abstract (english)

Assessment of noise mitigation measures in urban environments on example of urban agglomeration road is presented in this paper. Different measures are tested in Masarykova street in Zagreb. Tests are made by specialized software LimA. Tested measures are: turning street into pedestrian zone, free flow speed in night periods, traffic diversion from main road, and combined usage of pavement by cyclists and motor vehicles with maximum speed 30 km/h. The results are compared with egzisting noise levels. Two measures which showed positive results in mitigation of noise levels are turning street into pedestrian zone and traffic diversion from main road. Measures of free flow speed in night periods and combined usage of pavement by cyclists and motor vehicles aren't contributed to noise mitigation.
