Abstract：In order to effectively predict and evaluate the traffic noise distribution of Nanjing Olympic Sports Center around,the motor vehicle noise emission model prescribed in the national standard was localized corrected to fit for local road scene based on the measured traffic and noise data.The distributions of the traffic noise under different traffic control measures were simulated and evaluated.For Nanjing Olympic Sports Center,the influences of different traffic control measures on the noise distribution were calculated and analyzed by setting up 8 different traffic control measures.The results show that the flow limit,the speed limit and setting the control area all have the effect of noise reduction.But,the flow limit of large vehicles has lower effect.In addition,the integrated measures including flow limit,speed limit,setting the control area and flow limit of large vehicles can achieve a better effect of noise reduction.
