The specification of the D

16、ecentralized Environmental Notification (DEN) basic service was initially developed in the European Car-to-Car Communication Consortium (C2C-CC) Manifesto i.2 and in C2C-CC Message description: Decentralized Environmental Notification Message i.3. The service was evaluated by several initiatives, su

17、ch as the C2C-CC demonstration in 2008, by ETSI Plugtest events and European projects including PRE-DRIVE C2X, DRIVE C2X, SafeSpot, CVIS, CoVeL, SCOREF, simTD, etc. These evaluation efforts have provided feedback to ETSI TC ITS. The present document replaces ETSI TS 102 637-3 i.16 in whole. It inclu

18、des improvements and enhancements of the DEN basic service specifications in ETSI TS 102 637-3 i.16 according to the feedback provided by the various initiatives.

21、.2 (2014-11) 8Introduction ITS use cases are distributed over multiple instances of ITS stations (ITS-S). ITS-Ss interact in the ITS networks to provide a large diversity of co-operating customer services that satisfy different types of functional and operational requirements. ETSI TC ITS has define

22、d a “Basic Set of Applications“ (BSA) in ETSI TR 102 638 i.1 that can be deployed within a three-year time frame after the completion of their standardization. In BSA, the Road Hazard Warning (RHW) application is composed of multiple use cases with the objective to improve road safety and traffic ef

23、ficiency using vehicle-to-vehicle and vehicle-to-infrastructure communication technologies. ETSI TC ITS defines the decentralized environmental notification (DEN) basic service that supports the RHW application. The DEN basic service is an application support facility provided by the facilities laye

24、r. It constructs, manages and processes the Decentralized Environmental Notification Message (DENM). The construction of a DENM is triggered by an ITS-S application. A DENM contains information related to a road hazard or an abnormal traffic conditions, such as its type and its position. The DEN bas

25、ic service delivers the DENM as payload to the ITS networking Communications Architecture“. 3 ETSI TS 102 636-3 (V1.1.1): “Intelligent Transport Systems (ITS); Vehicular Communications; GeoNetworking; Part 3: Network Architecture“. 4 ETSI EN 302 931 (V1.1.1): “Intelligent Transport Systems (ITS); Ve
