Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
TC204 Intelligent Transport Systems, WG8, Public Transport and Emergency Services, have been
discussing enhancement of surface public transport information provision to surface public transport
users including international travellers around the world by using ITS technology.
WG8, Public Transport and Emergency Services, have been trying to harmonize current surface public
transport information provision interface national and regional standards, mainly, the TRANSMODEL
standard developed by CEN and the TCIP standard developed by the American Public Transportation
Association in the USA. However, because these surface public transport information standards are
widely accepted and used for system implementation in their regions, there is no perceived need or
demand to harmonize them.
Because WG8’s responsibility is to make surface public transport more convenient by realizing stress-
free surface public transport user information provision, WG8 has reached the conclusion that it has
to establish one International Standard (but not a technical report which has no binding rules) which
is defining basic framework that will fit above current national and regional standards. The accepted
national and regional standards (at this point in time, TCIP and TRANSMODEL) will be allowed to define
the specific information interfaces such as data format, stop point numbering system, etc. that are
necessary to the implementation of surface public transport information systems.
This part of ISO 17185 will be beneficial for all ISO/CEN member countries, as well as non-ISO/CEN
member countries, because this part of ISO 17185 will be a valuable “text book” to detail basic framework,
as well as highlight and encourage use of currently available national and regional standards such as
TRANSMODEL, TCIP, and possibly others. The intention is that, by deploying these national and regional
standards by other countries or regions, duplication of cost and time is avoidable. For those countries
that do not have surface public transport information standards, this approach allows more rapid
development and deployment of public transport systems that enhance usability and convenience.
This part of ISO 17185 is specifically set at a higher level and not aiming to harmonize currently
available national and regional standards to allow the use of these robust standards which are set at
various levels (for example, implementation specifications versus application level standards) but which
also experience widespread acceptance in their regional standards. This part of ISO 17185 intends to
establish a basic solid foundation for surface public transport user information provision framework and
is specifically limited to this scope to avoid conflict with those currently available regional standards.
This part of ISO 17185 is intended to be fully consistent with those currently available national and
regional standards which might be related to international surface public transport. In fact, in the
case of international surface public transport, surface public transport operators already have
transport-related information systems. However, it is not often the case that surface public transport
users, including international travellers, are provided with static and real-time information including
bus/train/tram locations appropriately and timely. This part of ISO 17185, and its scope and approach,
will solve this issue by setting basic framework for surface public transport information provision while
embracing existing national and regional standards.
INTERNATIONAL STANDARD ISO 17185-1:2014(E)
Intelligent transport systems — Public transport user
information —
Part 1:
Standards framework for public information systems
1 Scope
This part of ISO 17185 defines the framework for the realization of efficient public transport user
information provision to surface public transport users including international worldwide travellers.
In the surface public transport user information provision area, a set of regional and national standards
have already been established by related regional and national standardizing bodies.
This part of ISO 17185 defines basic framework for user information provision for surface public
transport users, from the viewpoint that the surface public transport users should be provided with
proper static and real-time information when it is most desired and effective. In order to realize the
desirable information provision, surface public transport information has to be efficiently gathered,
processed, and provided to surface public transport users in an appropriate way by using currently
available regional standards.
This part of ISO 17185 does not aim to define a new part of ISO 17185 that supersedes current regional
and national standards related to surface public transport. It aims to define the basic framework of
surface public transport user information provision by esteeming existing regional standards and
wisely using them.
This part of ISO 17185 does not aim to define specific information interfaces such as data format or a
stop point numbering system. The currently available regional standards established by regional and
national groups are suggested to be applied in that scope.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
data
reinterpretable representation of information in a formalized manner suitable for communication,
interpretation, or processing
Note 1 to entry: Data can be processed by humans or by automatic means. [ISO/IEC 2382-1:1993, (01.01.02)]
Note 2 to entry: Adapted from ISO/IEC 15944.
3.2
database
collection of electronically stored descriptive records or content units (including facts, full texts,
pictures, and sound) with a common user interface and software for the retrieval and manipulation of

Note 1 to entry: The units or records are usually collected with a particular intent and are related to a defined
topic. A database can be issued on CD-ROM, diskette, or other direct-access method, or as a computer file accessed
through dial-up methods or through the Internet.
Note 2 to entry: Licensed databases are counted separately even if access to several licensed database products is
effected through the same interface.
Note 3 to entry: A common interface providing access to a packet of serials or digital documents, usually offered
by a publisher or vendor, is also to be counted as database. Additionally, the single serials or digital documents are
counted as serials or digital documents. [ISO 2789:2013, 2.3.10]
Note 4 to entry: Adapted from ISO 9707.
3.3
data model
graphical and/or lexical representation of data, specifying their properties, structure, and inter-
