NOTE 2 to entry Within many ITS reference architectures, physical objects are placed into one of five categories: centre, support, field, vehicle or traveller.
architecture view from the physical viewpoint
NOTE 1 to entry The term “deployment view” is sometimes used within the broader ICT community, but the term “physical view” is preferred to prevent confusion between the physical view of a reference architecture and any part of a deployment architecture.

[SOURCE: ISO/IEC/IEEE 42010:2011, 3.6]
with respect to process oriented decomposition, the Information Architecture defines the entities and the relationships of information (Data model) and the principal data constructs (see Process Oriented and Logical Architecture)
NOTE The Information Architecture is not specific to any location
architecture based on political or administrational infrastructure partitioning and its division of responsibilities (rather than functions)
<enterprise view> element that represents coordination between two enterprise objects
specific form of a system architecture for use as a tool in the initial stages of an ITS implementation; non specified system design for a family of functionally different ITS systems, interconnected to operate in consort; it is the non specified system design for a family of functionally different systems, interconnected to operate in harmony. An ITS architecture can be described from different viewpoints, and from multiple viewpoints by conceptual, logical and / or physical representations.
NOTE An ITS Architecture is not specific to any single location. Additional terms may be explicitly referenced in individual standards or references to the source definition explicitly provided.
a subsystem of a TICS system, assembly, or other major element of a system which does not have, by itself, independent operational functionality
framework that tells designers how elements of hardware and software are to operate in harmony using common protocols and air interface techniques (where applicable)
architecture viewpoint used to frame concerns related to all layers of the Open Systems Interconnection (OSI) stack and related management and security issues
architecture view from the communications viewpoint
NOTE 1 to entry Within ITS, the preferred model for describing the communications view is based on the ITS-S reference architecture.

installation capable of performing one or more ITS applications
NOTE 1 to entry An ITS deployment typically refers to the support, central and roadside ITS stations coupled with a tacit acknowledgement of the mobile ITS stations that will communicate with the support, central or roadside ITS stations.

NOTE 1 to entry Characteristics often include but are not limited to functional, performance and interface requirements.

viewpoint showing how the “building blocks” from the physical viewpoint (or the functional viewpoint) can be allocated to the different types of organisation (or organisations themselves if known) that will be involved with the ITS implementation
