From page 30...
... Such calibration could facilitate using OBSI data in traffic noise prediction such as is done in the FHWA Traffic Noise Model. Suggested Research To enhance the results of this research the following topics are suggested for further research: • Investigations of the effects of temperature and wind conditions on OBSI measurement.
