12、-,-,- ISO 15784-3:2008(E) iv ISO 2008 All rights reserved 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 committe
13、es. 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 Inte
14、rnational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International S
15、tandards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the su
16、bject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15784-3 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.

19、raffic management are varied because internationally there are many kinds of roadside modules for traffic management, such as signal controllers, dynamic message signs and vehicle detectors. In the development of standards for data exchanges between a traffic management centre and roadside modules u
20、sed for traffic management, ISO/TC 204/WG9 agreed that the concept of a single standard for all countries and devices might not be appropriate, but a set of standards for different types of roadside module might be more appropriate. As a result, ISO/TC 204/WG9 adopted the philosophy of producing pro
21、file documents to specify how data should be exchanged. In the development of this part of ISO 15784, reference was made to the existing standards about profiles, specifically NTCIP 8003 which is the US standard for a profile framework, and ISO/IEC TR 10000, which is a series of Technical Reports un
22、der the general title Information technology Framework and taxonomy of International Standardized Profiles. The purpose of a profile is to specify the use of one or more base standards to provide a requested function. Because there are multiple functional requirements to data exchange between a cent
23、re and the roadside modules, ISO 15784 defines multi-part profiles. This part of ISO 15784 defines only the application profile. End application data is defined in the data-registry. Each country should define lower layer profiles based on the internationally standardized protocols because each coun
24、try has its own circumstance on communication infrastructure.

26、erved 1 Intelligent transport systems (ITS) Data exchange involving roadside modules communication Part 3: Application profile-data exchange (AP-DATEX) 1 Scope The purpose of this part of ISO 15784 is to define an application profile referring ISO 14827 and other base standards. The application prof
27、ile specified in this part of ISO 15784 is used to exchange data and messages in the following cases. a) Between a traffic management centre and roadside modules for traffic management. b) Between roadside modules used for traffic management. The scope of this part of ISO 15784 does not include the
28、communication between roadside modules and in- vehicle units, in-vehicle communication, in-cabinet communication or motion video transmission from a camera or recorded media. 2 Normative references The following referenced documents are indispensable for the application of this document.
