Description / Abstract:
This part of ISO 14813 provides a description of the primary
services that an ITS implementation can provide to ITS users. Those
services with a common purpose can be collected together in "‘ITS
service domains'" and within these there can be a number of "‘ITS
service groups'" for particular parts of the domain. This part of
ISO 14813 identifies thirteen service domains, within which
numerous groups are then defined.
In this version of this part of ISO 14813 an indication has been
provided to show the relationship of each service to
Cooperative-ITS. Cooperative-ITS provides services that have
previously been unavailable, notably those for ITS users who are on
the move. For many other services, Cooperative-ITS can actually be
seen as a "delivery mechanism" that can be used to enhance their
use and availability. Thus for some services, Cooperative-ITS is
essential, whilst for others it adds value. However for a small
number of services it is not relevant.
This part of ISO 14813 is intended for use by at least two
groups of people involved in the ITS sector. The first group is
those looking for ideas about the services that ITS implementations
can provide and the second is for those who are developing
standards.
For the first group, this part of ISO 14813 provides service
descriptions that can act as the catalyst for more detailed
descriptions. It is possible for the level of detail to differ from
one ITS implementation to another, depending on whether or not a
national ITS architecture is involved, and whether this
architecture is based directly on services, or on groups of
functions.
For standards developers, this part of ISO 14813 is applicable
to the working groups of ISO TC 204 and other Technical Committees
who are developing standards for the ITS sector and associated
sectors whose boundaries cross into the ITS sector (such as some
aspects of public transport (transit), plus inter-modal freight and
fleet management). This part of ISO 14813 is designed to provide
information and explanation of services that can form the basis and
reason for developing standards.
This part of ISO 14813 is in itself, by its nature, advisory and
informative. It is designed to assist the integration of services
into a cohesive reference architecture, plus interoperability and
the use of common data definitions. Specifically, services defined
within the service groups shall be the basis for definition of ‘use
cases', ‘user needs' or "user service requirements' depending on
the methodology being used to develop the resultant ITS
architecture functionality, along with definition of applicable
data within data dictionaries, as well as applicable communications
and data exchange standards.
