Abstract

This paper consists of tree principal parts. The first part discusses the problem of safety of Slovak level crossings, seen through the statistic data, and explains distinctive features identified on the base of comparison with level crossings operated in other EU countries. The second part deals with knowledge-based approach applied to diagnostics of electronic/computer-based level crossing installations. In the last part the authors present their methodology which has been designed and which is to be applied to the level crossing systems of a particular producer and describe possible architectures of such a system.

Keywords: Level crossing, diagnostics, knowledge-based approach, safety, statistics.
