International audience; The aim of this study is to propose a method for the evaluation of railway passengers' comfort in relationship to temperature, noise, and vibration. Estimated the single comfort for every sensation considered, the global comfort is evaluated with the Hyper-Sphere Method proposed by Corriere & Lo Bosco [1]. The humanvehicle- infrastructure-environment variables which influence comfort are individuated. Thus their value and correspondent global comfort could be evaluated in management strategy or predicted in design problem. The results show how to construct the hyper-sphere in which the surface is representative of best possible condition for human comfort and the centre represents the minimum.
  • The results below are discovered through our pilot algorithms. Let us know how we are doing!
