Use case / Anwendungsfall / Scénario d’utilisation

Railway Infrastructure Recording; Erfassung der Schieneninfrastruktur; nom descriptif en Francais

Description / Beschreibung / Description

There are several systems and projects that follow the aim to record and visualize railway infrastructure data in an economical, fast and accurate way. Information about the track geometry, topology and related infrastructure elements are dynamically recorded with a multi-sensor measurement unit and combined with image capturing. As a result the railway track will be visualized within a high resolution video based simulation. Further, measured data can be exported for utilization in other railway applications.

Data Flows and Interfaces / Datenflüsse und Schnittstellen / Flux de données et interfaces

Infrastructure data provided by the recording system include information about railway topology, track elements and operational elements of the railway network. All objects in the database are exported with a coordinate reference to further applications (e.g. simulators, onboard passenger information systems, timetable tools, construction planning).

Generic topology information (e.g. electrification, track classification, ocp attributes) can be imported from external sources, e.g. from a database provided by the infrastructure manager.

Characterizing Data / Charakterisierung der Daten / Caractérisation des données

This section serves to specify the required data regarding certain aspects.

How often do the data change (update)?

  • static (not changing)
  • yearly

How big are the data fragments to be exchanged (complexity)?

  • big (station/yard)
  • huge (region)
  • whole data set (network)

Which views are represented by the data (focus)?

  • Signaling
  • Geometry
  • Construction
  • Railway Operation
