17、telligent Transport Systems (ITS) are systems to support transportation of goods and humans with information and communication technologies in order to efficiently and safely use the transport infrastructure and transport means (cars, trains, planes, ships). Elements of ITS are standardized in vario
18、us standardisation organisations, both on an international level at e.g. ISO TC204, and on regional levels, e.g. in Europe at ETSI TC ITS and at CEN TC278. The present document specifies the architecture of communications in ITS (ITSC) supporting a variety of existing and new access technologies and
19、 ITS applications. The term ITSC denotes communications protocols, related management and additional functionality. The present document is arranged as a tool-box, i.e. conformance with the present document does not require to implement the whole functionality illustrated and partly specified in the
20、 present document. ITSC is to a large extent independent from specific communication technologies and specific ITS applications. The ITSC architecture is intended to be an open systems architecture, i.e. an architecture that is open and not proprietary. Activities related to the scope of the present

Access to public and private (local) networks including the global Internet. Infrastructure and satellite broadcast. ETSI ETSI EN 302 665 V1.1.1 (2010-09) 71 Scope The present d
25、ocument specifies the global communication architecture of communications for Intelligent Transport Systems (ITSC). This version of the present document is dedicated to the road transport context. The present document on the ITSC architecture specifies mandatory and optional elements and interfaces
26、of ITSC. Some elements of ITS applications, especially those directly related to ITSC, are also considered.
