COMPARISON BETWEEN MEASURED TRAFFIC NOISE IN KLANG VALLEY, MALAYSIA AND EXISTING PREDICTION MODELS
Many road traffic noise models are available around the world. However, these models cannot be simply generalized because local conditions affecting such noise (e.g., vehicle type and weather) vary from one locality to another.

| Summary: | Many road traffic noise models are available around the world. However, these models cannot be
simply generalized because local conditions affecting such noise (e.g., vehicle type and weather) vary
from one locality to another. Two traffic noise models used in this study are the L10 Calculation of
Road Traffic Noise (CRTN) model and Traffic Noise Model of Ontario Ministry of Transportation.
Using regression analysis, it was found that the predicted traffic noise levels by the CRTN model gave
satisfactory correlation with the measured values (R2 of 0.7109). The Traffic Noise Model Of Ontario
Ministry Of Transportation overestimated traffic noise level by 3.46 dB(A) on average. This study
proves that the improved Ontario Ministry of Transportation Traffic Noise model is satisfactory in
predicting traffic noise in a city with high percentage of motorcycle usage. This study also implies that
CRTN model is a valid model in predicting traffic noise levels for a city with high rates of motorcycle
use such Klang Valley, Malaysia.
