Introduction In cooperative Intelligent Transport Systems (ITS), the Local Dynamic Map (LDM) is a key facility supporting various ITS applications by maintaining the informat
23、ion on objects influencing or being part of ITS. The Local Dynamic Map therefore is relevant to the development of technical standards and specifications in order to ensure deployment and interoperability of cooperative systems and services described in the ECs ICT Standardization Work Programme i.7
24、. The LDM is a facility within the ITS station facilities layer as defined in the ITS communication architecture given in EN 302 665 i.1. Cooperative Awareness Messages (CAMs) as defined in EN 302 637-2 4 and Decentralized Environmental Notification Messages (DENMs) as defined in EN 302 637-3 5 are
25、important sources of data for the LDM. Moreover the LDM will support the Basic Set of Applications (BSA) outlined in TS 102 637-1 i.2 by providing plausible authorized, area related information in a time relevant manner. The BSA provides the application specific requirements for the LDM. ETSI ETSI E
26、N 302 895 V1.1.1 (2014-09) 6The following applications from the BSA are considered: Driving assistance - Cooperative awareness. Driving assistance - Road Hazard Signalling (see TS 101 539-1 i.3). Speed management. Cooperative navigation Location based services. Community services. ITS station life c
27、ycle management. ETSI ETSI EN 302 895 V1.1.1 (2014-09) 71 Scope The present document defines functional behaviour associated with a Local Dynamic Map (LDM) for usage in an ITS station unit (ITS-SU). It specifies functions and interfaces supported by a LDM. These functions and interfaces provide secu
28、re access to the LDM to manage LDM data objects stored in a LDM. It defines LDM data objects for safety-related and Vehicle to Vehicle (V2V)-related applications. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

47、lity) and scalability. However, within communications systems such requirements are normally considered to be related to procurement and, consequently, are not specified in the present document. 5.2 The LDM within the ITS-S communication architecture The LDM collects, qualifies (ensures that it is v
48、alid and from an authorized source) and stores data received from other ITS-Ss. The LDM may also collect, qualify and store information from other sources such as traffic information providers, or from its own sensors and applications. As shown in Figure 1, the LDM receives data from other ITS-Ss th

Information is exchanged with other services or applications by invoking functions located at the FA-SAP as outlined in EN 302 665 i.1. Security and management permissions are provided by functions which are located at the SF-SAP and the MF-SAP respectively.
