Use case / Anwendungsfall

Asset Status Representation for TMS

Description / Beschreibung

Traffic Management Systems (TMS) consider various sorts of input data for the calculation of the current traffic situation. One important input for TMS is the information about the railway infrastructure and its status. This comprises static information about the assets as well as dynamic information about the asset status.

Data Flows and Interfaces / DatenflĂĽsse und Schnittstellen

TMS receives static and dynamic data about the railway infrastructure from relevant databases under control of the infrastructure manager.

Characterizing Data / Charakterisierung der Daten

How often do the data change (update)?

The use case comprises static and dynamic (status) asset data. For infrastructure, the focus is only on static data.

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

  • Small (operational point)
  • Big (station/yard)
  • Whole data set (network)

Which views are represented by the data (focus)?

  • Construction: railway infrastructure elements along tracks
  • Operation: status of railway infrastructure elements

Which specific data do you expect to receive/send (elements)?
