Foreword This Technical Report (TR) has been produced
18、by ETSI Technical Committee Intelligent Transport System (ITS). Introduction In co-operative Intelligent Transport Systems (ITS), the Local Dynamic Map (LDM) is a key facility element which supports various ITS applications by maintaining the information on objects influencing or being part of traff
19、ic. The Local Dynamic Map therefore is relevant to the development of technical standards and specifications in order to ensure deployment and interoperability of co-operative systems and services in the ECs 2009 ICT Standardisation Work Programme. The ITS architecture i.2 identifies the LDM to be a
20、 key function within the ITS station facilities layer. Co-operative Awareness Messages (CAMs) i.1 and Decentralized Environmental notification Messages (DENMs) i.6 are important sources of data for the LDM. Moreover, a Basic Set of Applications (BSA) i.3 is defined, which can be realistically deploy
21、ed in a time frame of about 3 years after the end of their standardization. This contains several classes of applications which make use of information stored in the LDM. These applications are: Driving assistance - Co-operative awareness. Driving assistance - Road Hazard Warning. Speed management.
22、Co-operative navigation Location based services. Communities services. ITS station life cycle management. ETSI ETSI TR 102 863 V1.1.1 (2011-06)61 Scope The present document provides guidance on Local Dynamic Map (LDM) standardization based upon an analysis of the needs for standards for Intelligent
23、Transport Systems (ITS). The objective of the present document is to identify and characterize the elements of the LDM to be standardized to ensure interoperability between distributed applications and to provide applications support. It is also to identify and characterize the interfaces between th
24、e LDM, the other facilities functions and the distributed application elements which need to be standardized. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
