Unitary hybrid model of railway traffic

Abstract

The contribution deals with the methodology of building unitary hybrid simulation models reflecting railway traffic. Those models apply different level of abstraction (granularity) to diverse parts of a simulating system. Special attention is paid to different traffic models applied to microscopic and macroscopic elements of hybrid model. Because several different submodels coexist within a hybrid model, which are connected to different traffic indicators, it is necessary to solve the transformation of traffic flows on the interface of microscopic and macroscopic submodels.
