Architectures have been used as a part of the ITS implementation process for over 20 years. They provide stakeholders with a clear understanding of how ITS services are to be delivered so that informed decisions can be made as early as possible in the ITS implementation process. While the content, format, view points, and other details of architectures have evolved over time to better meet industry needs; this section provides an overview of the current best practices.
Reference architectures reflect the requirements set forth by the industry-wide stakeholder community.These architectures provide a relatively generic template that characterizes how ITS elements typically interact with one another to provide services that are widely deployed. At this level of abstraction,system elements are entirely conceptual – they describe types of elements that might be deployed.Because a reference architecture represents typical deployments, it is useful for identifying interfaces between system elements that can be standardized.
Planning architectures are intended to address stakeholder concerns in developing a long-term vision (e.g.5 to 20 years) of ItS deployments within a geographic area at a level that facilitates project planning. At this level of abstraction, the architecture identifies the specific system elements to be deployed and identifies which elements and ITS services are existing, if any, and which are merely planned. Ideally, the planning architecture should be used as the primary source for the deployment plans (e.g. timeframe) for each planned system element. Planning architectures should generally be derived from a reference architecture in order to benefit from the previous work and standardization,but the derivation process will typically omit some ITS services that are not envisioned for the region while perhaps also adding new ITS services that are specific to the region.
Deployment architectures are intended to address local stakeholder concerns related to a specific deployment project. At this level of abstraction, the architecture must identify the system elements that will be separately procured and identify how these system elements will interface with one another (ideally using some set of the standards created in response to the associated reference architecture). Deployment architectures should generally be derived from a planning architecture to provide consistency with the long-term vision but will generally only depict the subset of the planning architecture that is to be deployed as a part of the project.ISO 14813-5 pdf free.
