The work of preparing International Standards is normally carried out through ISO technical committees. E
8、ach 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 Internati
9、onal 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 Standa
10、rds 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 subject

12、s In-vehicle navigation systems Communications message set requirements 1 Scope This International Standard specifies message content and format utilized by in-vehicle navigation systems. Its emphasis is on messages that are required to generate or enhance routing instructions. There is a particular
13、 focus on messages that would not necessarily be included in a more general traffic management message list. Although this International Standard emphasizes requirements for Locally Determined Route Guidance (LDRG) systems that utilize on-vehicle map databases, it also includes messages that would b
14、e utilized primarily by Centrally Determined Route Guidance (CDRG) systems and certain value-added messages. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 Locally Determined Route Guidance System LDRG system which provides a driver with ste
15、p-by-step driving instructions that are determined by an on-vehicle system NOTE The system typically consists of a display screen, a computer, routing and guidance software, a navigable map database, and positioning equipment to track the vehicles location as it proceeds along its path. 2.2 Centrall
16、y Determined Route Guidance System CDRG system which provides a driver with step-by-step driving instructions that are similar to those offered by a LDRG NOTE With a centrally determined system, the routing instructions are determined at an off-vehicle location and transmitted to the vehicle. 2.3 me

18、raphic areas 1)2.5 traffic message centre TMC centre that transmits (receives) messages to (from) the vehicle by any communication means other than short range, vehicle-to-roadside communications (beacons) NOTE The bulk of these messages are expected to be traffic related. 2.6 roadside beacon RS sho
19、rt-range vehicle-to-roadside communication device with the inherent location feature that if the vehicle is receiving the signal, then the vehicle has to be positioned in a specific, localized area 3 Message set: Contents and format The messages in this International Standard are divided into three
20、categories, as follows. Messages that are required by route guidance systems to determine their recommended routes on-board the vehicle (LOCALLY DETERMINED). These address a wide range of information such as traffic conditions, tolls, road construction and availability of parking. Messages that are
21、required by route guidance systems for which routes are determined off-board the vehicle (CENTRALLY DETERMINED). These primarily focus on requesting and transmitting routing information. VALUE-ADDED messages that could be displayed by an in-vehicle navigation system, routed through a system, or util
22、ized by a system in providing guidance. These include messages for communicating information regarding items such as emergencies, toll and fee payments, and ridesharing. Tables 1, 2 and 3 consist of message contents and formats for locally determined route guidance systems, centrally determined rout
23、e guidance systems, and value-added messages. The structure of the tables is as follows. Item number: The alphanumeric number assigned to a message by ISO/TC 204. This signifies the messages relative position in the list and its classification: L = LDRG; C = CDRG; V = value added Message: A brief de
24、scription of the message. Data flow: IN means flow into the vehicle (navigation system) from the infrastructure (communication device); OUT means flow to the infrastructure (communication device) from the vehicle (navigation system). See Figure 1. 1) ITS standards for location referencing are being
25、developed within both CEN/TC 278, SWG 7.3, and ISO/TC 204, SWG 3.3. Oak Ridge National Laboratories in the US are working on a standard location message protocol. Japan utilizes a standard referencing system devised by the Japan Kokudo-Chiri-In. The field size estimates for location references in th
26、is International Standard are based on preliminary drafts from these efforts.

Note that this International Standard uses the same data fields in a mod
