Foreword
The text of the International Standard from Technical Committee ISO/TC 204 "Transport information and control
systems" of the International Organization for Standardization (ISO) a European Standard by Technical Committee
CEN/TC 278, "Road transport and traffic telematics", the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by December 2003, and conflicting national standards shall be withdrawn at the latest
by December 2003.
This document supersedes ENV 12313-1:1998.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
INTRODUCTION
Traffic and traveller information may be disseminated through a number of services or means of communication,
covering static displays, inter-active terminals and in-vehicle equipment.
For all such services, the data to be disseminated and the message structure involved in the various interfaces
require clear definition and standard formats, in order to allow competitive products to operate with any received
data.
This standard focuses on the data specification for TTI messages, their network layer and their service layer, to be
conveyed by the RDS-TMC feature, specified in IEC 62106:2000. Other standards are being developed by CEN/TC
278 Working Group 4 to cover TTI messages that may be conveyed by other carriers.
The following terms should be noted, to enable the TTI information chain to be more fully understood.
Data Service Provider: An organisation that manages any data service, by gathering data, processing data and
selling the data service. A Data Service Provider then negotiates for the use of the necessary data bandwidth with a
Broadcaster and/or Transmission Operator. A Data Service Provider is responsible for the "quality" of data to his
customers and must provide suitable customer support. Editorial control over the data may be part of a "data bit-
rate contract" agreement (for example an RDS-TMC service may require the Broadcaster to apply some editorial
control, so that both RDS-TMC messages and other broadcast services, such as spoken or teletext traffic and
travel information, possibly derived from more than one source, are not contradictory).
Programme Service Provider: An organisation that manages and originates programming and associated data for
broadcast. This will often be carried out by a Broadcaster but allows for the subtle distinction, where a separate
company is commissioned to produce a programme, together with associated data, e.g. text of teachers’ notes for
an educational series.
Broadcaster: A traditionally incorporated organisation responsible for a continuous strand of programmes, their
quality and programme associated data, as well as responsible for overall co-ordination of "broadcast
transmissions" (often a Broadcaster is the licensee of a national regulator). A Broadcaster may also be a
Programme Service Provider and sometimes be a Data Service Provider.
Network Operator: An organisation contracted to supply both programme and data circuits interconnecting Data
Service Provider, Programme Service Provider, Broadcaster and Transmission Operator. According to the
connections, various protocols may be used, e.g. ALERT-C, EBU Universal Encoder Communications Protocol.
Transmission Operator: Organisation responsible for the actual transmission of the full broadcast signal including
the audio programme, programme associated data and data services. Normally a Transmission Operator is
contracted to perform the transmission task by a Broadcaster.
Broadcasters already provide valuable TTI services to motorists, in countries throughout Europe, using spoken
reports and teletext inform
