CORRELATION OF RURAL HIGHWAY ROAD TRAFFIC NOISE WITH VEHICLE SPEED AND COMMERCIAL VEHICLE PERCENTAGES FOR THE DAY AND NIGHT TIME PERIODS

摘要

Road traffic noise and associated noise model predictions for rural highways are heavily influenced by the speed and number of commercial vehicles. It is in the public's interest to improve the accuracy of noise models to enable accurate representation of traffic noise impacts and design of appropriate noise mitigation treatment. A study has been carried out to measure road traffic noise simultaneously with traffic counts using commercially available noise and traffic count loggers. The correlation between traffic noise, vehicle type, variations between day and night and the effects of speed have been assessed at a rural location in South Australia. The correlations are presented for the purpose of gaining a better understanding of vehicle class noise emission values with respect to recognised noise models prediction for rural highways.
