Overview and analysis of methods for assessing ride comfort on tram tracks

U radu je dan pregled metoda za ocjenjivanje udobnosti vožnje na tramvajskim kolosijecima. Tramvajski se sustavi u brojnim segmentima razlikuju od standardnih željezničkih sustava, pa se stoga standardi razvijeni za standardne željeznice trebaju analizirati i evaluirati. Opisuju se metode ekvivalentne razine vibracija, Sperlingovog indeksa udobnosti vožnje te niz metoda predloženih normom EN 12299. Metode se uspoređuju na dvije probne tramvajske dionice ukupne dužine 21 km. Predložene su i preporuke za mjerenje udobnosti vožnje na tramvajskim kolosijecima.An overview of methods for evaluating comfort on tram tracks is given in this paper. Tramway systems differ in many aspects from standard railway tracks and, therefore, standards developed for standard rail lines have to be analysed and evaluated. Equivalent level of vibrations, Sperling ride index, and several methods proposed in EN 12299 are described, and these methods are compared on two trial tram sections 21 km in total length. Conclusions and recommendations for measuring ride comfort on tram tracks are presented
