A THEORETICAL STUDY ON ENVIRONMENTAL IMPACTS FROM URBAN ROAD NOISE FOR BUS PRIORITY

This paper studies the noise relationship between the automobile and the bus, so the theoretical model of road traffic noise is built for the urban bus transport, by which it is to academically prove, in the existing technology, the averaged noise of single bus can be equivalent to some qualities of automobiles and buses emission much more noise than the sum of the noise from automobiles. With the public transport system, a bus can has significantly less noise impact than the automobiles under the same capacity, including the role of rapid bus route. However, when the number of buses increased too much, the bus noise impact cannot be neglected and can be larger than the same capacity for the direct use of multiple automobiles.
