| 概要 |
Since the traffic behavior is heterogeneous and the number of motorcycle (MC) is dominant on the roads at Makassar City in Indonesia, to grasp the characteristic of the road traffic noise (RTN) such a...s the power level of the MC is needed when predicting the RTN at roadside areas in Makassar City. This paper shows the sound power level of the MC in Makassar City. The measurement of power level of MC is carried out at three roads in Makassar City. The peak level and the speed of vehicle ate measured to obtain the power level for MC. 425 data for MC with the dominant size of engine of 110cc and the speed between 20-40km/h are measured. The statistical analysis shows the power level has a good relationship with the speed. The results follow the trend of the power level in steady condition presented in the ASJ RTN-Model 2008 when the speed of vehicle is under 40 km/h. It coincides with the authors' previous research work. The prediction of the RTN by using the power level of motorcycle obtained in this paper provides more precise noise value.続きを見る
