19、ial to the present document. Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport System (ITS). The present document is part 3 of a multi-part deliverable covering Intelligent Transport Systems (ITS); Vehicular Communications; Basic Set of Ap

20、plications, as identified below: Part 1: “Functional Requirements“; Part 2: “Specifications of Cooperative Awareness Basic Service“; Part 3: “Specifications of Decentralized Environmental Notification Basic Service“; Part 4: “Operational Requirements“. Introduction ITS use cases are distributed over

21、 multiple ITS stations. Co-operating ITS stations are interacting to provide a large diversity of customer services that satisfy different types of functional and operational requirements. ETSI TC ITS has defined a Basic Set of Applications (BSA) i.8 that can be deployed within a three-year time fra

22、me after the completion of their standardization. In this BSA, the Road Hazard Warning (RHW) application is composed of multiple use cases. ETSI TC ITS defines the decentralized environmental notification (DEN) basic service that supports the various RHW use cases. The specification of this basic se

23、rvice is the purpose of the present document. The RHW application is an active road safety application that is distributed among vehicles ITS station and roadside ITS stations. The application execution is achieved through direct V2V / I2V communications. Furthermore, this application broadcasts use

24、ful information that is related to road traffic conditions. Consequently, roadside ITS stations may collect the broadcasted information from vehicle ITS stations, process the information and forward the information to a central ITS station in order to improve the traffic efficiency and traffic manag

25、ement. In this case, the application execution can be achieved through V2V/I2V and/or other communications as defined in 6. ETSI ETSI TS 102 637-3 V1.1.1 (2010-09)61 Scope The present document provides the specification of the DEN basic service, which mainly supports the RHW application. More specif

26、ically, the present document specifies the semantics of the Decentralized Environmental Notification Message (DENM) and the DENM handling. A DENM transmission is triggered by a cooperative RHW use case to provide information about a specific driving environment event or traffic event to other ITS st

27、ations. The ITS station that receives the DENM is able to provide appropriate HMI information to the end user, who makes use of these information or takes actions in its driving and travelling. The concept of the DEN basic service is derived from the functional requirements of BSA as defined in i.4

28、and operational requirements of BSA as defined in i.5. Detailed specifications of the RHW use cases are out of scope of the present document. The present document is based on DENM specifications defined in i.1 and i.2. 2 References References are either specific (identified by date of publication an
