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

Introduction
The ISO 18561 series is intended to facilitate the development, promotion and standardization of the
use of nomadic and portable devices to support intelligent transport systems (ITS) service provision
and multimedia use, such as passenger information, automotive information, driver advisory and
warning systems and entertainment system interfaces to ITS service providers and motor vehicle
communication networks.
This document provides the application and specification for standardizing transportation management
as a form of ITS in urban transportation networks to improve eco-mobility and sustainability. This
document fosters the introduction of multimedia and telematics nomadic devices in the public
transport and automotive world. These ITS technologies can increase operational efficiencies and
unlock enhanced transportation safety and eco-mobility applications.
Via nomadic devices, the urban mobility applications build on existing transportation planning
processes, including trip generation, trip distribution and modal choices with respect to extended
measures of effectiveness (MOE) in transportation models, such as time effectiveness, cost effectiveness
and green (eco)effectiveness.
In this document, the nomadic device is presented as a personal ITS station in order to communicate
with the other stations, including vehicle, roadway infrastructures and centres for defining the
requirements for interfaces between the stations in urban mobility applications to accommodate the
specific needs of eco-mobility in a smart city.

Part 1:
General requirements for data exchange between ITS
stations
1 Scope
This document gives guidelines for providing mobility information according to user preference on
demand, utilizing a variety of existing applications on nomadic devices related to different means of
transport. This document defines an integrated mobility information platform as a service methodology
to be integrated with a variety of mobile apps with respect to different transport modes.
This document defines the following urban mobility applications:
— guidance documents to facilitate the practical implementation of identified standards in the
transportation planning process, including related use cases;
— provision of urban mobility information integrated with a variety of mobile apps on nomadic devices
by multiple transport modes for collecting trip production and attraction data;
— modal choice data based on time effectiveness, cost effectiveness, and eco-effectiveness in the trip
distribution from origins to destinations.

4 Document overview and structure
The ISO 18561 series provides details of all documents and references required to support the
application of conventional transportation planning processes in transportation management with
respect to eco-effective measures to improve urban mobility by utilizing the data collected by NDs. The
ISO 18561 series is comprised of the following documents.
— Part 1 (this document): General requirements for data exchange between ITS stations
This part specifies the general requirements of data exchanges between ITS stations collected by
NDs in urban mobility applications based on the structure along with the use cases definition and
common set of resources (definitions, references) in green transportation management.
