COMPARISON OF NOISE EMISSION OF HCT AND CLASSIC VEHICLE COMBINATIONS FOR TIMBER TRANSPORTATION IN SWEDEN
Abstract
By means of a special simulation tool, the noise emission of a high-capacity heavy vehicle (11 axles) was compared to that of a classic heavy vehicle (a truck-dolly-semitrailer with 8 axles). The two cases are designated “Extended vehicle” versus “Classic vehicle” in this study, having total lengths of 34 and 25 m, respectively. The Classic vehicle represents the most common articulated heavy vehicle configuration for transport of timber and other goods in Sweden. Tyres were assumed to be typical of each axle and their noise emission values were taken from a recent study. Noise from the propulsion unit were assumed to just meet the present maximum legal levels. It was found that noise emission from the Extended vehicle is approx. 1.5 dB higher than for Classic vehicle, as max. A-weighted level per vehicle passage, but as the number of vehicles in traffic is lower for a certain transportation volume, the resulting road traffic noise exposure in terms of A-weighted equivalent level LAeq is similar. Consequently, noise emission is not a factor that gives either vehicle type a clear advantage over the other.
