Abstract

Carrying capacity of railway networks: interaction of line and node models G. Malavasi, S. Ricci University of Rome "La Sapienza " - DITS - Transport Area Italy Abstract Effective and widely tested models for the direct evaluation of the residual carrying capacity of the railway networks and the definition of the most effective actions for the full exploitation of this capacity are not yet available. The proposed approach is based on synthetic, probabilistic and combinatory models for links and nodes, interacting each other, sensible to the performances of the signalling systems and not depending upon the timetable structure. Traditionally the link models require the knowledge of the train succession and the node models are based on the hypothesis of independence by the surrounding links. In the paper the limits of this independence are analysed and the effects of the interaction between the network elements (links and nodes) are formalised. The resulting model allows to evaluate th
