Design of railway network model reflecting data structure non-oriented graph using Oracle spatial database for simulation of traffic

Abstract

This article deals with the design of a multilayer railway network model reflecting data structure non-oriented graph. Attention is firstly paid to motivation for using the railway network model to identify the rolling stock position, further, to describe railway infrastructure, its appropriate data representation and defining abstraction of the model considered. Subsequently the article focuses on algorithms enabling to build a multilayer railway network model with the use of base data files. The designed model reflects the data structure non-oriented graph and is implemented directly in Oracle database with the use of the Oracle Spatial and Graph technology. In the conclusion of the article we focus on the use of the railway network model in the rolling stock localization segment using computer simulation.
