Noise Pollution From Road Traffic in Urban Environment 785069

In the 1970's, the noise of road traffic was investigated in Budapest and in five rural towns /Gyðr, Szeged, Debrecen, Szombathely and Dunaujváros/ of Hungary. 650 measurements were made at 348 points of the towns. Relations among the equivalent A-weighted noise level and certain statistical levels were analyzed on grounds of the measurement results. The regional distribution and fluctuations in time of road traffic were evaluated.
In parallel to the measurements, also a census of road traffic was taken. Relations among the various characteristics of traffic noise and traffic density were analyzed by mathematical-statistical methods. In addition to the simple first-degree relation also the second-degree relations considered to be more precise were determined. The relations thus obtained could be used for forecasting the noise of road traffic.
The measurement results were compared with the data of similar investigations conducted in Budapest /1959/ and in Szeged /1961/. On grounds of the final results, trends of vitiation of the situation were pointed out
