SAFETY PROBLEMS AND GLOBAL COMFORT IN RAILWAYS OPERATIONAL MANAGMENT

In the planning process of a railway intervention and in its operational management, it needs to analyse carefully the relations between the different classes of variables constituting the complex system “vehicle-infrastructure-environment” to find the most suitable actions in optimisation the travelling comfort and safety, with respect for the ecosystem compatibilities. The problem can be tackled, in a systematic way, according to set theory and vector analysis, in a hyperspace Âd of d-dimension up to determining a characteristic global comfort vector that can be combined with each alternatives of intervention in the transport network examined. From this point of view, after the proper ach…
