Abstract
Implementing a Railways Operational Topology based on INSPIRE: An Interoperability Improvement with RINF

Co-Author: Jose Gomez Castano, Software developer at ADIF, Spain National Railways

To perform railways operations it is necessary to have the best network topology as possible. This has been traditionally created using a database with alphanumeric attributes, and every organization follow a different scheme to do it. The emergence of spatial databases allows incorporate geographic information, and Annex I to Directive INSPIRE, provides data models needed to enhance analysis capabilities, which improves performance and allows us the use of new tools based on spatial analysis. On the other hand the Register of Infrastructure (RINF) initiative, which consists of a register at European level of rail infrastructure also attempts to model a network topology, this alphanumerically, where the position of the elements are managed as a pair of numeric attribute. In this work an implementation of INSPIRE is developed, and this model allows to build a complete operational topology of the railways network with examples about how it is possible to perform daily operations. Several layers arise from this approach, to respond different needs as traffic planning and regulation, topology studies, speed restrictions impact on the traffic, interoperability with other OGC Services, etc. The model has the advantage of being interoperable and not subject to a specific organization exclusively. This approach allows an open access to the railways topology to a wide variety of companies, making a more competitive scenario where every one can provide its own experience. Furthermore a method of relationship between INSPIRE and RINF is shown, so that alphanumeric attributes can be used directly in the spatial analysis.
