The evaluation of the "acoustic climate" near transport routes, using the numerical method is possible only when we know the values of the para¬meters describing single noise sources and those of the parameters connected with the attenuating properties of the area adjacent to the route. The paper presents a method for determining these parameters. Direct measurements of the equivalent level were also made. Good agreement between measurement results with values calculated according to the present analytical and theore¬tical method shows its correctness and thus its usefulness for the problem of shaping the acoustic environment near roads with freely flowing traffic.
