The European reference data model for public transport is an offer to public transport companies and other
providers of services related to the process of passenger transportation and information, to suppliers of
software products supporting these processes, and to consultants and other experts acting in the field of
public transport in the widest sense.
The reference data model can support the development of software applications, their interaction or
combination in an integrated information system, and the system¿s organisation and information management
which rules the utilisation of the existing telematics environment in a company (or group of companies)
running computer applications supporting the different functional areas of public transport.
Although primarily designed to document the information needs of a public transport company in a well
defined and structured way, the reference data model can also serve as a starting point and reference for the
definition of a database schema. A database schema is needed for the physical implementation of data
storage systems to be used by applications directly, or for exchange of data between applications via
interfaces. Apart from that, such a database will often additionally be used as a source of information for the
company management and/or as an information pool for all employees who may need access to the
information basis of the company.
Ein effizienter öffentlicher Personenverkehr sowie eine genaue Fahrgastinformation ist das Bestreben von Verkehrsunternehmen. Der Notwendigkeit der Integration verschiedener Informations- und Datensysteme wird durch die Ausarbeitung dieses Daten-Modelles für den öffentlichen Personenverkehr entsprechend Rechnung getragen. Das Daten-Modell ist als Hinweis auf der konzeptionellen Ebene aufzufassen und beschreibt folgende Bereiche: Fahrplan; Personaldisposition; Automatische Fahrzeugüberwachung (AVM); Fahrgastinformation; Fahrgeldeinhebung; Management Informations-Systeme (MIS). Ein Interface, das für Geodaten entwickelt wurde, ist ebenfalls beschrieben.
