Noise Measurements for 24-hour periods were made at various microphone positions at six sites adjacent to existing roadways. Traffic volume and speed measurements were made simultaneously with noise measurements. The noise measurement sites were surveyed using standard surveying techniques to determine distances and elevations, relative to the roadway, of microphone positions and noise barriers for input into the Michigan Traffic Noise Prediction Program and the Transportation Systems Center Traffic Noise Prediction Program. Noise level predictions were made for each site using the two prediction programs. The measured and predicted noise levels were statistically compared to determine the accuracy of the programs. A method to produce corrections to predicted levels was developed and corrections for the six noise measurements sites were determined. /FHWA/
