The effect of tram track permanent way closure system on the level of noise

摘要

The paper deals with the analyses results of the noise level measurements carried out on the five different types of tram track permanent way closure while varying the following key parameters: load, speed and the type of the tram vehicle. The study involves the performance of the tram vehicles that are operating in the city of Zagreb. Measurement results were used for the choice of the system of the tram track permanent way closure. In addition to the noise level, the criteria included the economy of the performance and maintenance as well. The choice refers to the tram track closure system that is not separated from the road traffic, which means that the same traffic surface is shared by the road and tram vehicles. The next closure system proved to be optimal for the tram tracks in a separated lane.
