ROAD TRAFFIC NOISE PREDICTION WITH THE CONSIDERATION OF THE RELATION BETWEEN TRAFFIC VOLUME AND VEHICLE SPEED
In the prediction of road traffic noise, the traffic volume (Q) and vehicle speed (V) are essential parameters for the calculation. These two parameters are highly correlated and the relationship between them is often expressed by so-called Q/C-V/Vd curve in traffic engineering. Based on this relationship, noise levels in LAeq were calculated for typical types of roads according to the road traffic noise prediction model "ASJ Model 1998" proposed by the Acoustical Society of Japan in 1998. As a result, it has been found that LAeq does not increase lineally with the increase of traffic volume and it has upper limits. The maximum value of LAeq is about 63 (1.2m high for the bank) - 80 (12 m high for the cut) dB for freeways with 6-lanes, about 78 dB (1.2m high) for urban flat roads with 4-lanes, and about 54 (with noise barrier of 1.5 m high) - 67 (without noise barrier) dB for access roads with 1-lane.
