A TICS architecture is a framework for TICS deployments. It is a high level description of the major elements and the interconnections among them. It provides the framework around which the interfaces, specifications and detailed TICS systems designs can be defined. A TICS Architecture is not a product design, nor a detailed specification for physical deployment, and it is not specific to any one location. The title 'Systems Architecture' is perhaps the closest general terminology, but that term is sometimes too specific to include the conceptual aspects included in the terminology 'TICS Architecture' and also often implies a location specific solution.

The purpose of a TICS Architecture is to maximise efficiency, interoperability and multimodality of multiple interacting TICS systems in a complex and developing sector.

• Terminology to be used when documenting or referencing aspects of architecture description in TICS standards.
• The form in which aspects of System Architecture are to be documented and described in TICS standards.

In compiling this part of ISO/TR 14813, the authors have assumed that contemporary systems engineering practices are used. Such practices are not defined within this part of ISO/TR 14813.
