DATEX II is the electronic language used in Europe for the exchange of traffic information and traffic data. The development of DATEX II was initiated in the early 90s because of the need to exchange information between traffic centers of motorway operators. Soon there was the need to open this information to service providers. DATEX I was somewhat too limited for this and used outdated technical concepts. Which is why DATEX II was developed in the early years of this millennium. By means of DATEX II, traffic information and traffic management information is distributed in a way that is not dependent on language and presentation format.
NeTEx (CEN TS 16614-1, 16614-2 og 16614-3) is a CEN-standard which defines the data format and description for public transport data exchanges. The standard is based on Transmodel (EN 12896), and the reference model for permanent objects required for access to public transport: IFOPT (Identification of Fixed Objects in Public Transport, EN 28701).
NeTEx supports the exchange of data necessary for stop place information, journey planning, and ticketing, and is divided into three main categories:
Network Topology (CEN TS 16614-1)
Scheduled Timetables Plan data (CEN TS 16614-2)
Fare Information (CEN TS 16614-3)
Telematics are the technologies used to transmit information over long distances. In rail, TAF and TAP systems comprise:
Telematics applications for Freight services (TAF): including information systems (real-time monitoring of freight and trains), marshalling and allocation systems, reservation, payment and invoicing systems, management of connections with other modes of transport and production of electronic accompanying documents.
Telematics Applications for Passenger services (TAP): including systems providing passengers with information before and during the journey, reservation and payment systems, luggage management and management of connections between trains and with other modes of transport.
