The design of railway network infrastructure model for localization of rolling stock with utilization technology oracle spatial and dynamic database views

Abstract

In its first part, this article discusses various options for the localization of rolling stock, with an emphasis on regional lines. The following part focuses on the description of the three-layer rail network model design reflecting an undirected graph. The proposed model is used for simulation of rolling stock traffic and induction of various non-standard situations, detection of which could be used as a supplementary aid to dispatching traffic control. Further attention is aimed on optimizing search operations ORACLE database and designing of the optimization using dynamic views.
