ITS can create clear benefits in terms of transport efficiency, sustainability, safety and security.To tak
22、e full advantage of the benefits that ICT-based systems and applications can bring to the transport sector, it is necessary to ensure interoperability among the different systems.Cooperative systems are ITS (Cooperative ITS) systems based on vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I,
23、I2V) and infrastructure-to-infrastructure (I2I) communications for the exchange of information. Cooperative systems have the potential to further increase the benefits of ITS services and applications.Cooperative ITS is a subset of the overall ITS that communicates and shares information between ITS
24、 stations to give advice or facilitate actions with the objective of improving safety, sustainability, efficiency and comfort beyond the scope of stand-alone systems.The European Commission issued Mandate M/453 6 7 to invite the European Standardization Organizations (ESOs) (CEN, CENELEC and ETSI) t
25、o prepare a coherent set of standards, specifications and guidelines to support the European Communitys wide implementation and deployment of Cooperative intelligent transport systems (Cooperative ITS).CEN and ETSI have formally accepted the Mandate and will develop standards (EN) and technical spec
26、ifications and guidelines requested as far as possible within the timescale required in the Mandate. (see Reference 7)Annex C of Reference 7 proposes a “List of minimum set of standards and allocation of responsibility between CEN and ETSI Mandate M/453”.ISO/TC 204 decided in 2009 to join CENs effor
27、ts and to create a new working group (WG 18) under the Vienna agreement. This Technical Report is considered by non-European NSOs as important enough to justify having it under ISO lead.Different ITS stations (vehicle, nomadic, roadside and central) exchange geographically located information, which
28、 is of importance for the different cooperative applications (standards to be developed under the responsibility of CEN and ISO).This Technical Report delivers information about the status at the time of publication of the Local Dynamic Map (LDM) concepts as they have been developed in the different

31、es according their priority to the data storage and retrieving the response; LDM SAPs/Data access interface for writing elements into and retrieving elements from the data storage; LDM Broker shared data management for multiple application access.All the data elements and their attributes put in and
32、 out the LDM have to comply with the definition given in the LDM Data dictionary.5.1.1 Data elements and protocolsThe input to the LDM may come from many sources likely using different protocols. Messages originating from vehicles, for instance CAM and DENM, use a highly condensed protocol format to
33、 keep channel blocking at a minimum. There is only a minimum of additional information contained in the message itself to decide on reliability and confidence. Other input sources are radio broadcasts (RDS, DAB, DVB, DMB) using, e.g. TMC or TPEG protocol, traffic centre using DATEX/DATEX2 or HTML-ba
34、sed application data exchange format and so on. If data from different sources addressing the same event have a contradicting meaning, the following additional decision-relevant information has to be considered to get the most accurate information: Who is the issuer of the information? How and when
35、was the information generated? What is the accuracy of the information? How was the information transmitted? Where and under which condition is the information valid?5.1.1.1 TPEG in detailDetailed information on TPEG is provided in 21.TPEG (Transport Protocol Experts Group) specifications9 offer a m
36、ethod for transmitting multimodal traffic and travel information, regardless of client type, location or required delivery channel (e.g. DAB, HD radio, Internet, DVB-x, DMB, GPRS, Wi-Fi ). Language independence has also been a prime principle in the design.5.1.1.1.1 How does TPEG work?In contrast to
37、 TMC (event-based road traffic information), TPEG refers to a whole set or toolkit of specifications, for offering a wider range of services to a wider range of users and devices.TPEG services are defined in a modular way and can therefore vary in a number of “directions”: application, e.g. Road Tra
38、ffic Messages, Public Transport Information or Parking Information. Each Application is uniquely identified by an Application ID (AID) that are allocated by the TPEG Application Working Group (TAWG) of TISA;4 ISO 2015 All rights reservedPD CEN ISO/TR 17424:2015 ISO/TR 17424:2015(E) transmission meth
39、od, e.g. DAB digital radio, DMB, Internet; location referencing method, e.g. table-based (using for example TMC location tables) or on-the-fly (using a method that gives a location reference that works with or without maps and does not require a look-up table to decode in the receiver); device, e.g.
40、 intended for vehicle navigation systems, Internet browsers or mobile devices; conditional access: whether data are sent for free or only to users/devices who have somehow established the right to receive it, e.g. by paying a subscription. Encryption of TPEG data are possible by means of Standardise
41、d Encryption Indicators, which are allocated by the TPEG Application Working Group (TAWG) of TISA.The term “profile” is used to define a combination of the above which, together, make up what one might think of as a single TPEG service. For example: displaying traffic incidents on a map graphic and
42、supporting re-routing or route optimization; displaying public transport status information on a cell phone screen.5.1.1.1.2 TPEG Service IDsAny TPEG-service is uniquely identified worldwide by a TPEG Service ID (SID) consisting of three elements called SID-A, SID-B, SID-C, as described in ISO/TS 18
43、234-2. TISA, as worldwide registrar for TPEG SID, is responsible for allocating and maintaining TPEG Service IDs in a Registry to ensure a worldwide unique identification of a TPEG service.Each TPEG Application is assigned a unique number called the Application Identifier (AID) which is standardized
44、 in ISO/TS 18234-1. An AID is defined whenever a new application is developed. The AIDs allocated at the time of publication of this Technical Report are the following (see Table 1):Table 1 TPEG AID tableAID Number (Hex) Application Abbreviated term0 Service and Network Information application SNI1

Wi
47、th the aim to support sustainable mobility in Europe, the European Commission has been supporting the development of information exchange mainly between the actors of the road traffic management domain for a number of years. In the road sector, the DATEX standard was developed for information exchan

At the time of publication of this Technica
49、l Report, the second generation DATEX II specification also pushes the door wide open for all actors in the traffic and travel information sector.Much investment has been made in Europe, both in traffic control and information centres over the last decade and also in a quantum shift in the monitoring of the trans-European transport network (TEN-T). This is in line with delivering the objectives of the EasyWay programme 17 for safer roads, reduced congestion and a better environment. Collecting information is
